Land Rover Range Rover2011


A new, class-leading V8 diesel engine, new 8-speed transmission, two significant Terrain Response upgrades and subtle external styling all combine to ensure the 2011 Range Rover retains its crown as king of the luxury SUV segment.

The LR-TDV8 4.4-litre with parallel sequential turbocharging replaces the outstanding LR-TDV8 3.6-litre and is unique to the Land Rover Range Rover. An all-new 'super-diesel', the LR-TDV8 combines superior power and massive torque with unparalleled levels of refinement. Despite the extra performance, this sublime V8 engine is cleaner too, delivering even lower fuel consumption and CO2 emissions than its predecessor and meeting the stringent EU5 emissions standards. The headline news, though, is that the combined cycle fuel consumption of the new LR-TDV8 4.4-litre is just 30.1mpg, making this the first Land Rover Range Rover ever to better 30mpg.

With 313PS and 700Nm torque, the Range Rover's new powertrain matches power with conscience, reducing CO2 emissions by an impressive 14 percent. The new diesel engine is helped in this respect by its marriage to an impressive new, electronically controlled, ZF 8HP70, 8-speed automatic gearbox tuned by Land Rover engineers to combine silky smooth shifting with exceptionally rapid response and outstanding fuel economy.
Available only on 4.4-litre LR-TDV8 models, this 'smart' transmission integrates with the diesel engine to deliver the most efficient operating regime in all conditions. To reflect the performance of the new 4.4-litre LR-TDV8, diesel models are fitted with the same Brembo-based braking system fitted to the 5.0-litre LR-V8 supercharged model. Providing the immense stopping power required for only the highest performing vehicles, the system comprises 380mm ventilated front discs with unique, lightweight aluminium six-piston opposed action monoblock calipers. 365mm ventilated discs with single piston sliding calipers are fitted at the rear.

A new Exterior Design Pack option gives customers the chance to give their Land Rover Range Rover a more individual look and new colours and wheels have been added to the range.

e_TERRAIN TECHNOLOGIES for reduced emissions
e_TERRAIN TECHNOLOGIES are specifically designed to target emissions and improve efficiency of Land Rover vehicles, without compromising luxury, refinement or all-terrain capabilities.

The 2011 Range Rover gains the remarkably efficient 4.4-litre LR-TDV8 engine which realises a reduction in CO2 emissions of 14 percent from 294g/km to 253g/km compared to the outgoing 3.6-litre LR-TDV8 which it replaces. The new LR-TDV8 also complies with the latest EU5 emissions regulations which significantly reduces emissions of HC, CO2 and NOx.

Increasing the capacity by 22 percent over the 3.6-litre LR-TDV8 equates to a lower specific output than the smaller engine, significantly reducing emissions of engine-out NOx. The new ceramic glow plugs operate 250°C hotter than the previous steel units and are more durable. These factors make it possible to run the glow plugs for a longer period after start-up (100 seconds) and more frequently, improving efficiency and reducing emissions. The LR-V8 petrol was designed to deliver superior low-end torque from the outset and is packed with state-of-the-art efficiency features.

The new ZF 8HP70 8-speed transmission is tuned to take advantage of the LR-TDV8's low end torque with torque converter lock-up being selected as early as possible to reduce slip and energy loss. The wider ratio spread, tall overdriven top gear and the fact that no more than two internal clutches are open at any one time all contribute to improved fuel economy and emissions.

The Land Rover Range Rover's Intelligent Power Management System ensures the alternator is charging the battery (and drawing energy from the engine) at the most efficient times, such as when the vehicle is coasting rather than accelerating. The electrical system is scaled such that the battery only needs to be charged to 80 percent, reducing the workload on the alternator. It also moderates the charge rates in cold weather when the battery is less able to cope with high charge rates, increasing battery life for lower cost and environmental impact.

    * 4.4-litre LR-TDV8 engine technology
    * Engine optimised for maximum efficiency
    * Capacity increase of LR-TDV8 aids lower emissions
    * Ceramic glow plugs improve efficiency
    * Higher torque, tall gearing
    * Reduced torque converter slip on petrol and diesel
    * Transmission promotes fast engine warm-up
    * Intelligent Power System Management (IPSM) including smart regenerative charging

Despite these dramatic reductions, power and torque have soared, from 272PS and 640Nm, to 313PS at 3,750rpm and a staggering 700Nm torque at just 2,000rpm. More important is the way the power and torque interact with one another for impressive overall performance. Maximum torque is available from 1,500rpm to 3,000rpm but then maximum power kicks in from 3,250rpm to 4,000rpm producing a wall of performance from idle onwards. None of this has been achieved at the expense of refinement though and the 4.4-litre LR-TDV8's power delivery remains silky smooth and whisper quiet throughout the engine speed range.

Parallel sequential turbocharging - summary of advantages:
    * Most of the time only one turbocharger is in use (up to motorway cruising speeds and average acceleration). Because it is a medium, rather than large-sized turbo with variable geometry, response is excellent with no discernable lag.
    * Packaging is excellent, one turbo and manifold below each bank of cylinders.
    * The combination of two turbochargers makes it possible to optimise efficiency and performance at all times.
    * Because one turbocharger is in use most of the time, pumping losses are reduced.
    * More efficient than series turbocharger systems, whose smaller primary turbocharger increases pumping losses and fuel consumption through raised exhaust back pressure.

The third generation common rail fuel injection system mirrors that of the 3.0-litre LR-TDV6 operating at a pressure of up to 2,000bar. Eight-hole piezo injectors, (compared to seven hole in the 3.0-litre LR-TDV6) are further optimised for emissions and contribute to the engine's EU5 status and minimise noise. In the past, common rail fuel pumps were designed to over-supply the injector rails, the surplus being re-circulated back to the tank. This approach raised fuel temperature significantly and meant the fuel had to be cooled before being returned to the tank, wasting energy. The new system supplies fuel on demand, increasing efficiency and reducing the amount of cooling required.

The LR-TDV8's ancillary drive-belts have been reduced from seven ribs to six compared to the outgoing 3.6-litre LR-TDV8, making it possible to reduce the thickness of the pulleys, improving efficiency, saving weight and reducing the length of the engine by 4mm. The use of a stretch belt to drive the fan and a dynamic tensioner for the 6-rib alternator belt does away with any need for adjustment during servicing in both cases.

Smart charging improves efficiency
Clever energy management means no fuel is wasted in the production of energy for the Land Rover Range Rover's electrical systems. Land Rover's IPMS (Intelligent Power Management System) ensures the alternator does no more work - and the engine consumes no more fuel - than is strictly necessary. Rather than maintaining the battery charge state at an unnecessary 100 percent, IPMS aims to maintain the battery at 80 percent charge to avoid the alternator working harder than it needs to. The alternator is configured to charge wherever possible when the car is slowing (rather than when accelerating) recovering kinetic energy in the process. Charge rates from the powerful 220amp alternator (which replaces the 150amp unit of the 3.6-litre) are carefully moderated when cold to prolong battery life.

Safety first and foremost
The Land Rover Range Rover can be optionally equipped with a radar blind spot monitoring system to warn of vehicles and objects in the blind spot area. A Surround Camera system makes life much easier in car parks, as well as for towing and off-road manoeuvring and the patented 'reverse tow assist' provides screen-based guidelines to help with those difficult reversing-while-towing manoeuvres. Emergency Brake Assist and optional Adaptive Cruise Control complete the Land Rover Range Rover's package of active safety features.

Interiors offer unparalleled luxury
The Range Rover's European leather trim for headlining and door casings combined with sumptuous leather seat trim and upgraded waterfall lighting, cosset the occupants in luxury. The 12-inch TFT instrument display provides greater versatility than conventional instruments while the 8-inch Dual View infotainment screen displays a different image to driver and passenger. This means, for example, the driver can view the navigation display while the passenger watches a video.

Since MY2010, Land Rover Range Rover navigation systems have featured hard drive storage for mapping data so there's no need to buy DVDs, while 'towards guidance' supports the junction map and icon-based information with images of the actual road signage you see en-route. The portable Audio Interface supports connection to a wide range of audio storage devices including USB sticks and MP3 players. There's also a dedicated iPod connector port developed exclusively by Land Rover to prevent the iPod coming loose over the roughest terrain.

During MY2010, with chauffer-driven passengers in mind, the already incomparable level of exclusivity for rear seat passenger was further improved by the addition of optional, electronically-controlled, reclining rear seats. Operated by the passenger, the seats have internal heating and cooling functions as well as airline-style winged head restraints and four-way adjustable lumbar support.

The rear seat controls also include a facility for moving the front passenger seat forward to gain extended legroom when the front seat is unoccupied. The luxurious rear-seat passenger environment becomes even more opulent with the addition of laminated rear-door privacy glass which has the added benefit of reducing interior noise levels.

These exceptional levels of comfort are further enhanced when customers choose the option of a Logic 7, 1200W Harman Kardon High Dynamics Audio System. Widely acknowledged as one of the finest in-car audio systems in the world, the Logic 7 has 15 independent channels driving 19 premium quality speakers.
