Whitley, UK, February 20 2013 - The
highly-acclaimed all-new Range Rover is offering customers
increased powertrain choice with the introduction of the advanced
new LR-V6 supercharged petrol engine.
The state-of-the-art 250kW 3.0-litre V6 supercharged combines
effortless performance and exceptional refinement with enhanced
fuel efficiency, and provides an attractive new engine choice for
key global markets which favour smaller capacity petrol
engines.
"The all-new Range Rover has received a tremendous reception in
the marketplace, and this exciting new V6 supercharged engine will
broaden its appeal still further," said John Edwards, Land Rover
Global Brand Director. "It combines the desirability of the world's
finest luxury SUV, with the enhanced sustainability offered by this
advanced downsized petrol engine."
The engine's advanced supercharged design is ideally suited to
the all-new Range Rover, delivering smooth, seamless performance
with generous torque throughout the rev range.
Paired with the slick and responsive eight-speed automatic
transmission, the 3.0-litre V6 supercharged offers drivers an
effortless and confident drive, reaching 100kph from rest in just
7.4 seconds.
With CO2 emissions the LR-V6 supercharged achieves a 15 percent
reduction over the 5.0-litre LR-V8 naturally aspirated.
From the outset, the new engine has been engineered to support
the Range Rover's full breadth of capability, including extreme
off-road tilt angles up to 45 degrees, wading depth of 900mm and
towing weight up to 3,500kg.
The LR-V6 engine is now available to order in key markets
worldwide, with customer deliveries scheduled to commence in the
third quarter of this year.
State-of-the-art V6 engine design
The 3.0-litre LR-V6 supercharged petrol engine has been
developed by Land Rover powertrain experts from the award-winning
5.0-litre LR-V8 unit which has successfully powered the previous
generation of Range Rover models.
The 3.0 V6 supercharged shares many of the V8's key technologies
including direct injection, variable valve timing and aluminium
construction. It offers comparable levels of refinement and
driveability to the naturally-aspirated version of the V8 engine,
but with greater specific output and efficiency courtesy of
supercharging technology.
Land Rover engineers are established leaders in the field of
high-efficiency supercharger systems, following their experience
with the supercharged 5.0-litre LR-V8 engine.
"This new V6 draws upon the advanced technology of our V8 design
to create a highly efficient, downsized power unit," said Ron Lee,
Director of Powertrain Engineering, Land Rover. "Supercharging has
enabled us to deliver the effortless, refined performance which has
become a distinguishing character of Range Rover engines."
With a peak output of 250kW at 6,500rpm, the 3.0-litre LR-V6
supercharged has been developed to offer exceptionally strong
torque throughout the engine speed range, producing maximum torque
of 450Nm between 3,500 and 5,000rpm.
The new quad-cam V6 shares its all-aluminium construction with
the V8, with the lightweight die-cast block supplemented with
cross-bolted main bearing caps to increase rigidity and therefore
refinement. The four-valve cylinder heads are constructed of
recycled aluminium.
The valves themselves are subject to control by a dual
independent variable cam timing (DIVCT) system which is activated
by the positive and negative torques generated by the movement of
the intake and exhaust valves. This variable timing system features
actuation rates of more than 150 degrees per second throughout the
rev range, to optimise power, torque and economy at all engine
speeds.
This responsive and uninterrupted power delivery is made
possible through the use of spray-guided direct injection (SGDI)
which delivers precisely measured quantities of fuel directly into
the centre of the combustion chambers at pressures of up to 150bar.
The fuel is delivered several times during each combustion cycle,
creating a more homogenous air-fuel mixture for cleaner and more
efficient combustion.
To further maximise combustion efficiency, the LR-V6
supercharged features spark plugs which are precisely oriented both
in relation to the injector and within the combustion chamber. The
compression ratio is also raised from 9.5:1 in the supercharged V8
to 10.5:1, further improving fuel economy and reducing
emissions.
Key to this engine's high-specific output and efficiency is the
latest-generation Roots-type twin vortex supercharger which is
mounted in the 'V' of the engine. A water-cooled intercooler
reduces the temperature of the intake air to optimise power and
efficiency. New to the 3.0 V6 supercharged is that the supercharger
boost control is electronically supervised by new Bosch engine
management software, offering efficiency gains of up to 20
percent.
In creating the new 3.0 V6 supercharged engine, Land Rover
engineers devised an innovative system of counter-rotating front
and rear balancer weights which lend it the same smoothness and
refinement characteristics as its larger V8 brother.
The LR-V6 supercharged has a unique pressure die-cast oil pan
which features a deeper profile and revised oil pick-up pipework to
accommodate extreme tilting angles of up to 45 degrees
fore/aft.
In addition, to cater for the all-new Range Rover's 900mm wading
depth, the V6 engine's belt drives are waterproofed, as are the
alternator, air conditioning compressor, power steering pump and
starter motor.
The 3.0 V6 supercharged powertrain is paired with the
eight-speed ZF 8HP70 automatic transmission, with a large spread of
ratios which allows the engine's prodigious power to be fully
exploited while optimising economy and emissions.
