A new 211PS version of the 3.0 LR‑TDV6 diesel will join the
existing 245PS engine in 2011, further enhancing the appeal of the
iconic Range Rover Sport. All diesel models are equipped with
Diesel Particulate Filters (DPF) as standard and all meet Euro 5
emissions making them among the cleanest diesel engines on the
market. The powertrain line‑up is completed by the fabulous 5.0
LR‑V8 supercharged as before, offering a combination of supreme
power and sublime refinement.
A new Limited Edition has also been added to the range as an
alternative to the sumptuously appointed Autobiography Sport. The
Limited Edition includes a set of unique interiors, finishes and
detailing not available as separate options, while the main range
also gains three new colours. The outstanding dynamics of the Range
Rover Sport are also improved by the addition of two new Terrain
Response features, Hill Start Assist and Gradient Acceleration
Control. "The Range Rover Sport already represents the last word in
high performance SUVs and we've made sure it retains that
reputation by adding a new 3.0 LR‑TDV6 diesel engine version, a
stunning new Limited Edition and further Terrain Response
enhancements providing even greater security for drivers,"
said Phil Popham, Managing Director.
New version of the 3.0 LR‑TDV6 joins Range Rover Sport range for
2011
A new entry level version of the EU5 3.0 LR‑TDV6 is being
introduced for 2011, making Land Rover's latest V6 diesel engine
technology available to a greater number of Range Rover Sport
customers. The new 3.0 LR‑TDV6 delivers 211PS at 4,000rpm and 520Nm
torque at 2,000rpm while achieving the same high levels of
refinement and response as the more powerful 245PS version. The 3.6
LR‑TDV8 has been discontinued.
The engine is equipped with the same parallel sequential
turbocharging system and third generation common rail fuel
injection system as the existing 245PS version. Throttle response
is staggering with maximum torque available from only 2,000rpm. The
new 3.0‑litre diesel can significantly out perform its rivals by
delivering 500Nm in only 500 milliseconds from idle. This means
drivers have instantaneous access to 83 percent of maximum torque.
When it was introduced last year, the parallel sequential
turbocharging system was the first of its kind to be fitted to a
V‑engine anywhere in the world. The twin turbochargers work
sequentially to provide best in class torque at low speeds and pack
a huge punch at high speeds.
Driving a turbocharger requires pressure from the exhaust,
creating pumping losses in the engine and increasing fuel
consumption. To minimise this effect, valves isolate the secondary
turbocharger both from the exhaust stream and the engine inlet
tract when it is not required. A balance pipe connecting the two
manifolds allows the gas from both manifolds to feed through the
primary turbocharger. A variable geometry, medium‑sized
turbocharger is in use most of the time during average acceleration
and up to motorway cruising speeds and performs with no discernible
lag. It is a more efficient system than series turbocharging in
which the smaller primary turbo increases pumping losses.
The 3.0‑litre LR‑TDV6 set new standards of refinement and fuel
economy when it was announced last year, with its third generation
common rail fuel injection system. Operating at 2,000bar, the piezo
injectors are designed to minimise noise while optimising
combustion. The system operates in 'metering mode' supplying just
the right amount of fuel to the injectors rather than returning it
to the tank and wasting pumping energy in the process. All diesel
models are now fitted with a DPF and have an advanced EGR system to
reduce NOx. "The new version of the 3.0 LR‑TDV6 will further
enhance the Range Rover Sport offering greater choice within the
range than ever before. Needless to say, both diesel engines
deliver the kind of stunning performance Range Rover Sport
customers have come to expect," said Paul Walker, Chief Programme
Engineer.
5.0 LR‑V8 supercharged engine continues to lead the pack
Land Rover's remarkable 5.0 LR‑V8 supercharged petrol engine
continues to head the Range Rover Sport powertrain range in 2011.
Developing 510PS and 625Nm torque it set new standards in petrol
engine design when it was introduced last year, packed as it is
with innovation design features aimed at boosting both performance
and economy. Despite its supreme levels of power and torque, the
LR‑V8 supercharged meets EU5 and has impressively low CO2 emissions
of 348g/km.
A centrally‑mounted, multi‑hole, spray‑guided fuel injection
system delivers fuel at a pressure of up to 2175psi (150bar)
directly to each cylinder. The injectors are positioned to deliver
fuel precisely to the centre of the combustion chamber for maximum
air‑fuel mixing and accurate combustion control. The charge cooling
effects of the direct injection system allow a high compression
ratio of 11.5:1 which further improves engine efficiency. During
the engine warm‑up phase, the combustion system employs multiple
injection mode strategies to deliver 50 percent more heat for fast
catalyst warm‑up and substantially reduced emissions.
A sixth‑generation, twin‑vortex system (TVS) supercharger feeds
air through twin intercoolers, water‑cooled by their own discrete
cooling circuit. The high‑helix rotor design improves the
supercharger's thermodynamic efficiency and does away with
traditional supercharger whine, making it almost inaudible. Air is
delivered through twin air boxes, which reduce flow loss and are
highly efficient. Mechanically, the new supercharger and its
intercoolers are neatly packaged in the V of the engine, helping
reduce engine height.
A number of other design features include the industry‑first,
torque‑actuated variable camshaft timing on all four cams. Unlike
conventional systems which rely on oil pressure, these are actuated
by the positive and negative torques generated by the opening and
closing of the valves, reducing energy consumption. Torque and
power is also optimised by a variable inlet manifold which changes
the length of its eight inlet tracts.
The manifold switches between a 680mm inlet tract to provide high
torque at low revs and a 350mm inlet path allowing maximum power at
high revs. The precise position is optimised throughout the rev
range at all times. The engine also features a unique reverse flow
cooling system where coolant passes through the cylinder heads
before the block. This allows the heads to remain cooler and the
knock threshold pushed further back for greater efficiency.
An oil to water heat exchanger also transfers heat from the
coolant to the engine oil. These features promote faster engine
warm‑up for reduced emissions and enables the cabin to warm‑up
faster too. Frictional losses have been reduced by the use of
Diamond‑Like Carbon Coating (DLC) on some components, an
intelligent oil pump pressure relief valve (PRV) to optimise oil
pressure and the use of lower viscosity 5W‑20 oil further reduces
parasitic losses without compromising durability. "The LR‑V8
supercharged engine has become a benchmark since it was introduced
last year, thanks to its huge power, torque and extremely high
efficiency. For an SUV where performance really matters, it is
simply without peer and an ideal power unit for the Range Rover
Sport," said Nick Rogers, Director of Range Rover Programmes.
6‑speed automatic transmission ‑ responsive and refined
Both the petrol and diesel engines are equipped with the
ultra‑refined ZF HP28 6‑speed automatic transmission. Its
characteristics have been optimised by Land Rover engineers to
provide the same class‑leading response and rapid, refined shifts
on all engines. Their superior power and torque characteristics
make it possible to actuate the transmission's lock‑up clutches
much earlier in each gear, reducing slip through the hydraulic
torque converter for optimum fuel consumption and CO2
emissions.
Advanced chassis, brakes and suspension
The Range Rover Sport 5.0 LR‑V8 Supercharged petrol and 245PS 3.0
LR‑TDV6 only, are equipped with the Adaptive Dynamics system which
operates in conjunction with the existing Dynamic Response system.
With Adaptive Dynamics, DampTronic Valve Technology™ replaces
conventional dampers and monitors damper pressure 500 times a
second, continuously adapting to surface conditions and driving
style thanks to an active valve technology. The chassis is
complemented by high performance braking systems which include
four‑piston opposed calliper front disc brakes on the diesel models
and lightweight aluminium, six‑piston Brembo callipers for the
supercharged models. A variable ratio steering rack improves
stability in high speed cruising and increases driver involvement
on twisting roads. The high performance character of the Range
Rover Sport chassis is further emphasised by the Roll Stability
Control system which responds to steering inputs from the driver
and intervenes by braking individual wheels if the possibility of a
rollover is detected.
Off‑road ability even further improved for 2011
When it comes to off‑road ability, Land Rover vehicles are
acknowledged as setting the standards for others to follow. For
2011, there are two additional functions, Hill Start Assist and
Gradient Acceleration Control.
Hill Start Assist retains the initial driver‑generated brake
pressure, long enough for the foot to move from brake pedal to
throttle without the car rolling backwards. The brake is released
after a sufficient time has elapsed or when the engine is supplying
enough torque to move the car up the hill. Hill Start Assist is
always available, not selectable and neither is its operation
indicated to the driver.
Gradient Acceleration Control is designed to provide safety cover
on severe gradients when the driver does not have Hill Descent
Control engaged. By pressurising the brake system, Gradient
Acceleration Control slows the car to a limit determined by the
throttle position when the car is descending the slope in the
driver's intended direction of travel. This includes descending the
slope forwards in drive, or rearwards in reverse. Otherwise (such
as descending while facing up the gradient with Drive selected)
Gradient Acceleration Control restricts speed to 5km/h (3.1mph) for
up to 20 seconds, allowing the driver to regain proper control.
"These new features enhance the outstanding ability of the Range
Rover Sport off‑road while continuing to deliver an intoxicating
driving experience on‑road. They also deliver an added layer of
safety and support to drivers who want to discover what their
vehicle is really capable of," said Nick Veale, Vehicle Engineering
Manager.
A new Limited Edition and three new colours
A new Limited Edition joins the Range Rover Sport line‑up for 2011
in addition to the Autobiography Sport which continues unchanged
for 2011. Available on the 3.0 TDV6 HSE and 5.0 V8 HSE derivatives,
the Range Rover Sport LE is sumptuously equipped with three unique
interior colourways which can be matched with three exterior
colours, Fuji White, Nara Bronze and Santorini Black. The LE is
distinguished from other models by a distinctive grille design with
an Oberon surround, gloss black mesh and noble plate frame. The
design of the side vents echoes this detailing with noble plate
logo, gloss black mesh and Oberon frame. LE models are also fitted
with distinctive 20 inch 5‑spoke Diamond Turned alloy wheels.
Luxury Pack
An optional Luxury Pack is also available on the 3.0 TDV6 HSE
bringing equipment levels close to that of Supercharged models. The
pack includes contrast stitching on selected upholstery, Titan
grille and vents, 20‑inch alloy wheels, Premium ICE, extended
leather pack, HSE Luxury badge, heated steering wheel and adaptive
cruise control.
e_TERRAIN TECHNOLOGIES boost economy and lower CO2 emissions
The new Range Rover Sport is laden with features aimed at reducing
both fuel consumption and CO2 emissions. Both the 245PS and 211PS
versions of the LR‑TDV6 3.0 Sequential Turbo Diesel engine are
designed to deliver class‑leading fuel economy and improved low‑end
torque.
The parallel sequential turbocharging system of the 3.0‑litre
diesel makes use of its larger, primary turbo most of the time. The
smaller secondary turbo remains dormant when higher power is not
required, reducing pumping losses and consequently, fuel
consumption. The highly efficient, third generation common rail
injection system with piezo injectors and fuel metering, also makes
a substantial contribution to fuel economy.
The high pressure, spray guided direct injection system of the 5.0
LR‑V8 supercharged optimises combustion while the variable camshaft
timing system, camshaft profile switching and variable inlet
manifold all join forces to ensure the engine is optimised for fuel
efficiency throughout the range. Thanks to the advanced cooling
system, faster warm‑up also improves fuel economy as do the low
friction design features.
All engines have been optimised for low‑end torque as well as
economy, making it possible to activate the lock‑up clutch of the
ZF HP28 automatic transmission at lower speed. This reduces 'slip'
in the hydraulic torque converter improving both fuel consumption
and CO2 emissions. The higher torque at lower rpm also enables
longer gearing for more economical cruising.
The Range Rover Sport incorporates several other energy saving
features too. At standstill, the idle speed of the 3.0 LR‑TDV6 is a
low 710rpm and the 5.0 LR‑V8 supercharged, 700rpm, using the
minimum of fuel without compromising refinement. An Intelligent
Power Management System includes Smart Regenerative Charging, so
whenever possible the alternator charges the battery when it is
most economical to do so, such as when the car is coasting rather
than accelerating.
Aerodynamic features at the front end such as the lower chin
spoiler and front wheel deflectors help to reduce drag by
increasing underfloor airflow. The air conditioning pump is
driven through a clutch which disengages when the air conditioning
is not in use reducing parasitic losses and delivering improvements
in fuel consumption and CO2 emissions.
