Dodge 2010 Heavy Duty Ram picks up new looks along with increased towing capacity.

2010 RAM Crew Heavy Duty

Combining the best in pickup design features makes the Dodge Ram Heavy Duty an exceptional work and play pickup that will have the attention of contractors, hunters fishermen and anyone else who hauls and tow more passengers and bigger loads.

“This is the continuation of the reinvention of our Dodge Ram lineup,” says Fred Diaz, President and Chief Executive Officer–Dodge Ram Brand, Chrysler Group LLC.

“During the past 5 years, Dodge has gained market share in the heavy-duty pickup segment, and to stay on that track, Dodge Ram keeps innovating. Our new 2010 Dodge Ram 2500 and 3500 pickups will continue to build on our momentum.”

The refinements shown in the new 2500/3500 Crew Cab, which further roots Dodge as a major player in the rapidly growing four-door heavy-duty pickup market, make it significantly better than the Quad Cabs it replaces.

Dodge has offered four-door Quad Cab pickups for years. But the rear doors were more ¾-size than full. The new Crew Cab, which replaces the Quad Cab of old, has full-size doors along with a long list of refinements and new features owners who use their pickups for work and recreation will appreciate.

Ram Mega Cab owners get the added benefit of having reclining rear seats thanks to the nine-inch longer cab. Center seat position folds up in all models.


We took advantage of a special ride-and-drive opportunity in San Antonio, Texas, to see first-hand how the engineering and design changes come together in the 2010 Heavy Duty Rams. The fleet of upper trim level (SLT, Laramie, TRX) 2500/3500 Ram Crews we drove ranged from two-wheel-drive, Hemi-powered models to Cummins-powered 4×4 Duallys. We drove them empty and loaded, on road and off.

The Heavy Duty Rams are more refined and more capable than the models they replace. You notice the difference before you even open the doors.

The front bumpers are taller and more akin to those found on big rigs; the hoods are taller and have louvers running down each side of the center bulge; the tow hook openings are larger; the grille taller; the front fenders and headlights match those of the Ram 1500; and the Dually rear fenders are now one-piece, giving the big daddy of Dodge tow vehicles a more refined appearance.

Changes to the front bumper, hood, grille, front fenders, headlights and the Dually rear fenders give the big Dodge a more refined appearance.

Inside we found even more changes to our liking. Many of the nice creature comfort and convenience features introduced in the ’09 Ram 1500, such as the well-bolstered seats, multiple storage compartments, soft-feel interior coverings, and available two-tier center consol, have been adopted in the new Heavy Duty Crew Cabs.

The 2010 Ram Mega Cab further enhances comfort by adding another nine inches to the back of the cab. Such extra space adds more storage space along with extra leg room in the back to go with the reclining rear seats.


The feeling of richness fills your senses when you buckle into either of the higher-end Crew Cab or Mega Cab models. The seats were very supportive in the right places, and the armrests and dash no longer exuded the cheap, hard plastic feel so often found in many of today’s pickups.

The interior was nicely laid out with storage compartments and nooks everywhere, including a dual glovebox. Plug-ins for accessories, like the cell phone charger and laptop were in the right locations as was the 120V inverter plug on the dash. Cup and bottle holders were plentiful, dash easily read, and controls made for big hands. It’s a truck you feel good in because everything fits.

Use of fluid-filled cab mounts greatly reduce the road jitters felt by drivers of the older Heavy Duty Rams.

That feeling is further bolstered as the miles roll beneath the wheels. The new Crew is significantly smoother, quieter, and overall more comfortable than its heavy-duty predecessor. There’s very little noise or vibration intruding into the cab.

Stronger front axle u-joints and re-turning of the 4x4 front suspension has increased front Gross Axle Weight Ratings on Cummins models by 600 pounds. Note exhaust brake is standard item as well.

The big Dodge’s refined ride quality is due in part to the nicer seats and reduction of wind noise though the small body styling changes and improved sound insulation between cab and engine compartment.

But it’s the fine-tuning of the connection between the cab and chassis with fluid-filled mounts and suspension components that significantly reduced the jitters and shakes felt in the old Quad Cabs—especially driving unloaded.


Heavy Duty Rams come standard with the 5.7L Hemi delivering 383 horsepower and 400 pound-feet of torque behind a heavy-duty five-speed automatic. But the majority of HD Ram buyers opt for the Cummins package ($7,500) with its 6.7L Turbo Diesel backed with either the standard six-speed manual or six-speed automatic.

The Cummins six generates 350 horses at 3,000rpm and a trailer-slinging 650 pound-feet of torque at 1,500rpm. Furthermore, Dodge says the 6.7L Cummins surpasses 2010 emissions requirements in all 50 states, has an oil change interval of 7,500 miles,  and a life-to-major overhaul interval of 350,000 miles, or more than 100,000 miles more than its closest competitor.

The engine’s low-end toque is massive and whether empty or loaded, the truck moves out quite briskly with no sense of turbo lag. It’s also quite content at freeway speeds; we found ourselves watching the speedometer a lot to keep from rolling along well above the posted speed limits.

Both 2500 and 3500 Rams can tow up to 5,000 pounds on the Class IV receiver hitch, which is standard on the truck. When properly equipped with a gooseneck, which Mopar offers as a dealer-installed accessory, the new Ram Crew 2500 2WD can tow trailers up to 13,450 pounds and payloads up to 3,160 pounds. (The 4×4 models lose about 700 pounds capacity across the board because of the added drivetrain components.)

If greater load-moving capacity is needed, the 2WD Cummins-powered 3500 Dually Crew Cab is king of the four-door parking lot with a maximum towing capacity of 17,150 pounds and a payload of 4,280 pounds in the 2WD ST (base-model.) All Cummins models come with a factory integrated exhaust brake, too.


From our initial driving impressions Dodge has proven a lot of small changes add up to a big difference, and in doing so the 2010 Ram Crew Cabs have set a new bar for overall performance and comfort in the heavy-duty pickup segment.

“We went all over the country to learn how people really use their heavy-duty trucks at work and play,” Diaz told us during the driving session. “We did our research with a cross-functional team, and what we learned, we brought to the process of creating the all-new 2010 Dodge Ram 2500 and 3500 Heavy Duty pickups.”

As for pricing, Dodge is pushing hard to make the new Crew Cab offerings quite attractive: The base model ST 4×2 is $1,970 less than the 2009 model it replaces, and the 4×4 models $40 less.

So across the board it seems you’ll be able to get into a 2010 Dodge Ram Crew Cab for less than a comparable 2009 Quad Cab—and reap all the benefits that come as a result the new Crew’s refinements.


2011 Ford SuperDuty gets an all-new powertrain.

Ford-Built PowerStroke

2011 Ford SuperDuty gets an all-new powertrain

Most of us wouldn't thrash our $60,000 pickups with off-road use, but at Truck Test Digest we want to make sure they are capable of handling some tough conditions.

Long has the battle raged over the merits of Cummins, Duramax and PowerStroke. That’s why the all-new, Ford built diesel is big news, especially to the Ford faithful.

When Bruce Smith and I test drove the new 2011 Super Duty in the desert hills of Arizona we were fortunate to have along on the drive Adam Gryglak, Ford’s lead diesel engineering manager. As many of you know, Ford’s Power Stroke engine was previously built by Navistar/International. No longer.  The all-new 6.7-liter Power Stroke V-8 turbocharged diesel was engineered, tested and built by Gryglak’s team at Ford.  The new engine puts out 735 ft.-lb. of torque and 390 hp. All while getting better fuel economy, being B20 compatible and meeting stringent new emissions standards.

All-new Ford-built PowerStroke

“Five years ago,” said Gryglak, “we started this new engine design literally with one single cylinder and worked our way out from there.” This fresh start resulted in some noticeably different design features, which produced the results the team wanted in power, quietness, durability and low emissions.

Common rail injector assemblies are located on the outside of the heads for easy maintenance access.

One of the most striking design elements is the inboard exhaust and outboard intake architecture. The cylinders were turned around so the exhaust runs down the middle of the V and the injectors are on the outside of the heads. This design reduces overall exhaust system volume, which leads to better throttle response.  The reduction in exhaust system surface area also minimizes heat transfer to the engine compartment and improves NVH (noise, vibration and harshness).

Other design features added to the improved NVH including new engine mounts, additional firewall sound deadening materials and five injection events per cylinder per cycle. “When the main injection occurs, we can mitigate NVH because we have a slower ignition process,” said Gryglak. “When the fuel burns, it doesn’t burn with a traditional pop or bang.”

The eight-hole piezo injectors are part of a high-pressure fuel system that injects fuel at more than 29,000 psi for optimum power and fuel efficiency.

Fuel efficiency is also helped by the light weight compacted graphite iron (CGI) engine block, which is stronger than cast iron. Ford has been using CGI in engine blocks in other products around the world for several years.

Another power-to-weight advantage is the DualBoost turbocharger design that allows the single turbo unit to deliver the benefits of a twin-turbocharger system in a smaller, more efficient package, combining the quick response of a small turbocharger and the power-building volume of a large turbocharger in one unit.

The exhaust gases that power the turbocharger are subjected to an array of technologies to comply with the 2010 federal emissions standards including the reduction of oxides of nitrogen (NOx). The exhaust aftertreatment system looks like a multi-stage rocket.

The system, in fact, has multiple stages. The first stage includes a diesel oxidation catalyst (DOC), which converts hydrocarbons into water and carbon dioxide. Next the exhaust gas is dosed with a urea solution that Ford calls diesel exhaust fluid (DEF). A tank of DEF lasts about 7,500 miles. The heated DEF splits into ammonia and carbon dioxide. The ammonia reacts with NOx to produce inert nitrogen and water.

Stage three of the rocket-resembling aftertreatment system is the diesel particulate filter (DPF) which traps soot, which is periodically burned away.

NOx is also reduced when the system runs the EGR through a two-step process utilizing separate cooling sources. Cooler EGR means more of it can be utilized.

Ford's new diesel is backed up by an all-new 6R140 heavy-duty TorqShift six-speed automatic transmission.

The diesel is backed up by an all-new 6R140 heavy-duty TorqShift six-speed automatic transmission. The new tranny’s torque multiplier provides better off-the-line performance. Long-travel, high-capacity turbine damper allows the torque converter to handle the torsional force of the new, Power Stroke. The damper also allows the powertrain to lug down to 900 rpm while still locked up, which allows the engine to run at a lower rpm for better fuel economy.

Drivers can select the manual function by pulling the shift lever into “M” and using the lever-mounted toggle switch to select gears. The display shows the selected gear and the control system will lock the torque converter and hold that gear for a full manual transmission feel.

The new TorqShift also features a PTO output gear, which is linked through the torque converter to the engine crankshaft so the power is available any time the engine is running. The PTO allows the transmission to power auxiliary equipment such as snowplows, aerial lifts, tow truck lifts, cement mixers or dump trucks. It can power other equipment via drive shaft or hydraulic pump.

I’m always impressed by the capability of the Super Duties when I test them on the off-road course. Tons of low-end torque makes for great crawling.  A new e-locker provides added traction in those twisted off-camber situations. A new hill start assist applies brake to prevent rollback and the hill descent control worked smoothly without all of the ABS noise and grinding experienced with similar systems.

The Super Duty really shines as a tow vehicle.  The new diesel provides more towing torque and the tranny will help control rpm and provide drive train longevity with excellent lockup for towing. The new transmission also provides a new tow/haul mode with engine exhaust braking.

The 2011 Super Duty is a great tow vehicle.

Ford continues to offer its integrated trailer brake controller, power folding and power telescoping mirrors and adds trailer sway control, which integrates AdvanceTrac® and Roll Stability Control™ as standard on all single rear wheel configurations.  Trailer Sway Control candetect yaw motion in the truck caused by trailer sway and applies precise braking or reduces engine torque to reduce trailer sway.

Also available for towing is a factory-installed and warranted fifth wheel and gooseneck substructure directly attached to the frame.  When your toys have been getting the best of your tow vehicle it may be time to step up to the new Super Duty.

Tech Savy

The all-new Super Duty is available with a 4.2-inch LCD screen that offers important information related to fuel economy and towing performance. The menu is navigated through a five-way button on the steering wheel.

“Our research told us that Super Duty customers use their vehicle as a mobile office every day to get the job done, and they want technology that will help them be more productive,” said Dante Williams, applications engineer.

“Our new LCD productivity screen helps them manage their trucks and their work for the benefit of their customers through more visual data, text data and displays,” Williams said. “The information is more complete and more detailed, but presented in an engaging, easy-to-use manner.”

The new LCD is positioned between the tachometer and speedometer, and the familiar Built Ford Tough “slam” greets the driver at key-on. Here are the six base menu options, each of which can be customized by the truck owner:


1. Gauge mode

  • Graphical compass display can be configured to rotate directions
  • Actual temperature of the oil and transmission (gas engine); turbo boost gauge for diesels


2. Trip computer

  • Information on two trips available
  • Trip time and mileage
  • Gallons of fuel used and miles per gallon


3. Fuel economy

  • Fuel history can be broken down to three time periods
  • Five resets are available to track fuel history
  • Fuel economy displays miles to empty, as well as average and instantaneous mpg


4. Truck applications: Engaging off-road mode; towing functionality

  • Off-road screen allows customers to see the lateral, vertical and turning radius of their maneuvers
  • Customers can access information about various features, depending on the model, such as Electronic Locking Differential, Hill Descent Control™, 4×4 system and traction control to help make informed decisions on what technologies might be of use in a given situation
  • Trailer tow customers can:
    • Name and change a trailer, allowing customers to track mileage and store gain settings via the Trailer Brake Controller on the instrument panel
    • Delete trailers
    • Access information on features such as Trailer Brake Controller or Tow Haul
    • Choose the type of trailer connected and go through a connection checklist – conventional, fifth wheel and gooseneck options are supported
    • Three distinct checklists can be accessed, and include:
    • Ball coupler connected and locked?
    • Tongue jack raised?
    • Mirrors adjusted?
    • Electrical wiring connected?
    • Lights functioning correctly (running lights, left/right turn and brake lights)?
    • TBC (Trailer Brake Controller) gain setting adjusted?
    • Wheel chocks removed?
    • Safety chains connected?


“The checklist can be especially helpful to a novice tower,” said Williams. “The screen takes customers through the process, so no matter what sort of connection they are using, they can tow with greater confidence.”



5. Settings

  • Turn features on or off
  • Change duration of lamps
  • Change compass zone
  • Change operating condition for maintenance schedules
  • Set oil life percentage


6. Information

  • The MyKey™ feature allows the owner to set driver preferences
  • The System Check screen displays information such as oil life, engine hours, engine idle hours and open doors
  • Warnings, such as “left rear door ajar,” can be displayed graphically
  • All-new messages and warnings include Trailer Sway Control, Hill Descent Control, tire pressure monitoring system and diesel-specific messages

All-New Gas Engine

An all-new 6.2-liter V-8 gasoline engine is standard on the 2011 Ford F-Series Super Duty.  The new engine delivers 405 ft.-lb. of torque (at 4,500 rpm) and 385 horsepower (at 5,500 rpm) on regular gasoline, which is an increase of 40 ft.-lb. of torque and 85 horsepower over the current 5.4-liter V-8.

“Our all-new 6.2-liter V-8 engine uses race-proven components and technology that have been optimized for the high performance and efficiency that our Super Duty customers demand,” said Mike Harrison, Ford V-8 engine programs manager. “It delivers not only significantly better torque and horsepower than current heavy-duty gas engines, but also improved fuel economy.”

Nearly all the components of the 2011 Super Duty 6.2-liter V-8 are shared with the 6.2-liter V-8 engine found in the 2010 F-150 SVT Raptor, a purpose-built, high-performance off-road truck versatile enough to take on the most challenging desert adventures as well as the everyday commute. In November 2008, the 6.2-liter Raptor R not only survived the grueling Baja 1000, it earned a podium finish.

Core to the improvements is the adoption of an all-new engine architecture with increased bore spacing that allows better engine “breathing” in both the intake and exhaust for more power and more overall efficiency.

The new gas engine runs on regular-grade gasoline, E85 or any blend in between.

Design features of the new 6.2-liter V-8 engine:

  • Large bore, shorter stroke: This approach to creating power has its roots in Ford racing engines from the past. The large bore (102 millimeters) allows for larger intake and exhaust valves for improved engine breathing, and the short stroke (95 millimeters) allows higher engine speed for increased horsepower. Still, peak horsepower is generated at a relatively modest 5,500 rpm.
  • SOHC valvetrain with roller-rocker shafts: The single overhead camshaft (SOHC) per cylinder head design results in a stiff valvetrain that allows optimized camshaft lift profiles and helps produce great low-speed torque. The roller-rocker shafts allow valve angles to be splayed, resulting in optimized intake and exhaust port layout for better breathing.
  • Dual-equal variable cam timing: Intake and exhaust valve opening and closing events are phased at the same time to optimize fuel economy and performance throughout the engine speed range and throttle positions.
  • Two spark plugs per cylinder: Because of the large bore size, two spark plugs per cylinder are used to more efficiently burn the fuel-air mixture in the combustion chamber, enabling better fuel economy and increased engine torque. The twin plugs also help the engine maintain a smooth, stable idle.
  • Dual knock sensors: A knock sensor on each bank of cylinders of the V-8 engine allows the spark timing of each cylinder to be individually optimized real-time, throughout the engine speed range. The system continuously monitors engine performance and applies this real-time learning to optimize timing via an adaptive algorithm.
  • Better engine crankcase breathing and efficiency: Significant development work and computer-aided engineering optimized the cylinder block for more efficient airflow in the crankcase as the pistons move up and down in the bores, resulting in improved torque at higher engine speeds. Piston-cooling jets squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions. The cooling jets also allow for a higher compression ratio for better engine efficiency and faster engine oil warm-up on cold starts, also improving fuel economy.

2008 Land Rover Sport

Land Rover Sport Packs Serious Performance in a SUV

by Keith Burton

Building on Britain’s distinguished history of sporting cars and surefooted off-roaders, the Range Rover Sport is the SUV engineered for anyone serious about expeditious driving.  Our tester was the supercharged version of the Range Rover Sport, and we have to recommend this engine with this premium version.

A naturally aspirated version with 300 horsepower is available, but the 390 horsepower supercharged version is just too much fun not to have.

Along with the engine, the Range Rover’s Dynamic Response suspension system, which is standard on the Supercharged edition is terrific.

Here’s a large, heavy SUV that has flat cornering, tight body control, and sharp steering response.  Powerful Brembo front disc brakes fill out the performance end , the special brakes are included in the Dynamic Response Package, and provide amazing stopping power and a nice feel to the foot.

Land Rover’s exclusive Terrain Response system provides the Range Rover Sport with remarkable off-road capability.  Add a long list of premium cabin features and the result is an SUV with a major accent on sport.

Improvements for the 2008 model year include:

  •  New power-folding exterior mirrors.
  • An eight-way power seat in the front-passenger position.
  • A new, power tilt and telescope steering wheel adjuster.
  • A tray with a rubber mat bottom surface located in front of the navigation screen.
  • New finish for areas of the center stack, console, and glove box release.
  • Leather door inserts are improved on the HSE.

On the Supercharged version, interior trim is now straight-grained walnut. Dark Zebrano trim is a no-cost option.

HSE models equipped with the optional Luxury package also have Straight-Grained Walnut trim with Dark Zebrano available as a free alternative.


Land Rover’s Integrated Body-frame construction marries a hydroformed-steel ladder frame to a highly rigid monocoque body.

The benefits are exemplary collision performance, efficient packaging, the stiff platform needed for superior handling and maneuverability, and a composed cabin environment.  Miniature dampers between the frame and body at mounting points and a tuned mass damper located at each corner of the vehicle help block the transmission of noise, vibration, and road harshness into the passenger cabin.

The Range Rover Sport uses high-tensile-strength boron steel to reinforce the roof pillars, magnesium in the front crumple zone, and aluminum for the hood.

A single-piece tailgate with a separate hinged glass not only provides convenient access to the cargo hold, it also trims aerodynamic drag.  Exterior steel panels are zinc coated on both sides for corrosion protection. Static glazing is bonded in place to contribute to the body’s structural rigidity.


Common traits shared by the Supercharged and naturally aspirated V8s that power the Range Rover Sports are aluminum block-and-head construction, chain-driven double overhead camshafts, and four-valve combustion chambers.

The 4.4-liter 32-valve naturally aspirated V8 features electronically-controlled infinitely-variable intake and exhaust timing and electronic throttle actuation.  Peak outputs are 300 bhp at 5,500 rpm and 315 lb.-ft. of torque at 4,000 rpm.

The 4.2-liter 32-valve supercharged and intercooled V8 uses thicker-walled cylinder liners for extra block rigidity, necessitating a slightly smaller bore dimension.  A belt-driven Eaton supercharger delivers a maximum 11.6-psi of boost pressure.

Twin air-to-coolant heat exchangers cool the pressurized intake charge en route to the cylinders.  The Supercharged V8 delivers a hearty 390 bhp at 5,750 rpm and 410 lb.-ft. of torque at a useful 3,500 rpm.

The Range Rover Sport uses a ZF electronically controlled six-speed automatic transmission that offers three modes – automatic, sport, and CommandShift (manual).  When the console-mounted lever is moved to its CommandShift gate, gear changes can be selected manually.

This is handy to match engine and road speeds during aggressive braking; a downshift is also beneficial to help power smartly out of a bend. Selecting the Sport mode provides a more responsive automatic shift program which allows the engine to rev high before an upshift. Downshifts are also more aggressive.

The Range Rover Sport’s two-speed transfer case features an electronically controlled, infinitely variable locking center differential that automatically distributes the available torque to both drive axles.

Shifting between low and high ranges is possible without stopping. A fully locked mode is available for severe off-road use.  An electronically actuated infinitely variable rear differential lock can be selected from the optional equipment list.


The Range Rover Sport’s performs on the road like an expensive sport sedan. This is remarkable considering its off road capabilities. Convincing an SUV to behave well both at higher speeds on paved roadways and while traversing challenging off-road terrain is no mean feat. The key components to do all this are:

An independent double-wishbone suspension system at each corner

High-capacity monotube dampers for consistent control of wheel and body motion

Electronically regulated air springs that provide automatic load leveling and three selectable ride heights—access (for entry), standard, and off-road; cross linking the air springs makes the best use of the long travel suspension system

Land Rover’s Dynamic Response system combined with Brembo® front brakes is standard on the Supercharged model and available on the HSE. Active anti-roll bars balance handling and manage body roll on-road. Relaxing the bars during off-road excursions provides the extra wheel articulation needed to maintain a secure footing

Speed-sensitive, variable-ratio ZF power rack-and-pinion steering for excellent feedback and optimum directional control

Cast aluminum-alloy wheels for low unsprung weight and excellent dispersal of braking heat

Wide, low-profile radial tires compounded for optimum performance both on- and off-road; the Range Rover Sport HSE is fitted with 255/50R-19 tires while the Supercharged edition is fitted with 275/40R-20 tires.

To match stopping power with acceleration and speed, four-piston front brake calipers supplied by Brembo are standard on the Supercharged edition and optional (in the Dynamic Response Package) in the HSE.  The parking brake is electronically applied by simply pulling a small console lever.

Bosch-supplied electronic controls deliver a full suite of stability and traction benefits including emergency brake assist (EBA) for maximum retardation when needed to help avoid an accident; ABS to curtail wheel lock during aggressive braking as well on slippery off-road terrain; dynamic stability control (DSC) to maintain guidance authority during extreme maneuvers; active roll mitigation (ARM) to slow the vehicle in a tight bend when the vehicle senses overly aggressive driving; electronic brake force distribution (EBD) to make balanced use of the stopping traction available at all four wheels regardless of how the vehicle is loaded; four-wheel electronic traction control (4ETC); and hill descent control (HDC) to creep controllably down steep grades.

The Range Rover Sport is no slouch off-road, it is one of the best out there if you can afford the potential damage to this premium SUV.  The Range Rover’s

Terrain Response System that takes the chore out of programming multiple systems for optimum performance. Setting a console knob in one of five available positions adjusts throttle response, optimizes the transmission’s gear changes, positions the air suspension at the appropriate ride height, and sets the center and rear differentials (when so equipped) in a mode right for the terrain.  DSC, 4ETC, ABS, and HDC functions are also altered by each Terrain Response setting.

The five available modes are general, grass/gravel/snow, mud and ruts, sand, and rock crawl.


An extensive array of premium features is provided to insure that long hours behind the wheel of Land Rover’s sport tourer are wholly satisfying to the most demanding driver.  Both front bucket seats are eight-way power adjustable and ergonomically designed for lasting comfort.  Firm bolsters and high-grip seating surfaces are provided to support occupants during the inevitable aggressive driving stints.  The cockpit array consists of a highly legible instrument cluster and a broad center stack rising out of a high console to locate all controls within easy reach.

The automatic climate control system provides independent settings for two distinct zones.  Heated front and rear seats are standard in the Supercharged edition and optional in the HSE.  A power sunroof is standard in both models.

The programmable key fob commands the air suspension to facilitate easy entry.  Adaptive cruise control that senses and adjusts to traffic in the lane ahead is available in the Supercharged model. A personal telephone integration system that uses Bluetooth technology to accommodate the owner’s mobile phone in a console cradle is standard in both models. A Park Distance Control system that senses objects both in the driver’s blind spots is standard.

Acknowledging that superb audio entertainment is an essential, not a luxury, both Range Rover Sport models are fitted with a harman/kardon LOGIC7 550-watt sound system armed with a 12-channel amplifier playing through 14 speakers.

AM/FM stereo, CD via a six-disc in-dash changer, and auxiliary-input (MP3) source material are efficiently orchestrated into a full surround-sound audio experience.  Steering wheel controls command volume, station and CD track selection. SIRIUS digital audio reception is standard in the Supercharged edition and optional in HSE (subscription is not included).  A rear-seat entertainment package consisting of two front headrest displays, a six-disc DVD changer, a remote control device and a touchscreen interface is an available option.

A DVD-based GPS navigation system with multiple state-of-the-art features is included to assure that every Range Rover Sport adventure has a successful ending.  Commands can be entered either by touching the seven-inch LCD screen or by voice.

The 4×4 Information screen presents the current settings of the Terrain Response™ system, the orientation and vertical position of the front wheels, the suspension setting, gear selected and transfer case range.  Navigation is provided during both on- and off-road excursions.

The Range Rover Sport HSE is available in eight exterior colors. Six colors are offered for the Range Rover Sport Supercharged. Three seat and two carpet colors are available in several attractive combinations.
