The outstanding 183kW 3.0-litre LR-SDV6 and entry level 155kW
3.0-litre LR-TDV6 diesels will now power the Discovery 4 with the
ZF 8HP70 8-speed automatic transmission, producing CO2 emissions of
just 230g/km and 224g/km respectively, whilst the 276kW 5.0-litre
LR-V8 naturally aspirated petrol engine is powered with the
ultra-refined ZF 6HP28 6-speed automatic transmission.
"The Discovery 4 continues to win awards for its
unrivalled versatility and breadth of capability, accommodating up
to seven passengers in comfort whatever the terrain. For 2013, the
breadth of choice gets better, with equipment upgrades and our new
Black Design Packs enhancing the key design attributes that our
customers identify with today. As the ultimate all-purpose vehicle,
the Discovery 4 is now more compelling than ever before,"
said John Edwards, Land Rover Global Brand Director.
New exterior & interior colours
On the outside, five new body colour choices are available on the
Discovery 4 at 2013 model year: Havana, Barolo Black, Barossa,
Mariana Black and Causeway Grey. The HSE derivative also offers a
new, 19-inch 7-spoke alloy wheel in Bright Silver finish.
There's broader customer choice on the inside as well, with two
new interior colours and two new trim finishers. Arabica seats with
Nutmeg stitching and Ivory seats with Ivory stitching are both now
available in Windsor premium leather. A new Grand Ivory Lacquer
veneer provides a striking and contemporary contrast with Ebony
facia and door casings, whilst new Gloss Black switch finishers on
the steering wheel have been added to the Grand Black Lacquer
veneer feature. Cosmic Grey interior finishers are also introduced
as a new option.
Infotainment system enhanced
For 2012, the audio system electrical architecture was upgraded to
the latest MOST Gen 2.1. This system has now evolved and for 2013
model year the radio has been upgraded to the latest generation
DAB+ and DMB-A broadcast formats and a new digital TV tuner has
been introduced across all derivatives, capable of receiving MPEG4
digital streams.
In line with the improvements introduced in 2012, the entry
level audio is an 8-speaker system with colour display and options
for Bluetooth, and USB/iPod connectivity; the High-line Harman
Kardon System has 11-speakers and an output of 380W, whilst the
Premium Harman Kardon LOGIC 7 system has 17 speakers and delivers
an amazing 825W.
Touch screen is available independently of the navigation system
and Rear Seat Entertainment (RSE) is equipped with a single slot
DVD drive in the audio head unit so the disc can be conveniently
loaded from inside the cabin.
The rear seat audio system incorporates WhiteFireTM cordless
headphones, and can also be controlled by wireless remote control.
The system supports connectivity with games consoles and video
playback of MP4 files stored on USB. The phonebook stores several
thousand entries, whilst the TFT Message Centre interface displays
audio, phone and navigational information.
Efficient, powerful and refined 3.0-litre
diesels
The tremendously responsive 3.0-litre sequential turbo diesel
engines come in two versions, 183kW and 155kW, producing 230g/km
and 224g/km CO2 respectively. The 3.0-litre 155kW engine replaces
the outgoing 2.7-litre V6 for the 2013 model year. Its superior
fuel economy reduces CO2 emissions from 244g/km for the 2.7-litre,
to 230g/km.
These diesel engines are equipped with the same parallel
sequential turbocharging system and third generation common rail
fuel injection system. Throttle response is staggering with maximum
torque available from only 2,000rpm. The 3.0-litre diesel can
significantly outperform its rivals by delivering 500Nm in only 500
milliseconds from idle.When it was introduced at 2010 model 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.
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. This is more efficient
than series turbocharging systems where the smaller primary turbo
increases energy losses.
The third generation common rail fuel injection system operates
at 2,000bar, the piezo injectors minimising 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 energy in the process. All diesel models
are now fitted with a DPF and have an advanced EGR system to reduce
NOx.
ZF 8HP70 automatic gearbox
Introduced on the new diesel derivatives, the remarkable ZF 8HP70
transmission delivers unrivalled response for driving pleasure
while driving fuel consumption and CO2 emissions down to an
all-time low. Eight speeds provide closer ratios and a greater
overall ratio spread, while the higher overdrive ratio compliments
the huge torque of the 3.0 LR-SDV6, reducing fuel consumption and
CO2 emissions. Efficiency is further improved by the internal
mechanical layout of the 8HP70 which means that no more than two
internal clutches are open at any one time.
The 8HP70 is packed with energy saving features. The hydraulic
actuating system is more efficient too, the hydraulic pump drawing
less energy from the engine. The torque converter is calibrated to
lock-up at lower speeds and operating temperature, reducing fuel
consumption and once again taking advantage of the 3.0-litre diesel
engine's immense low-end torque.
Transmission Idle Control seamlessly and transparently selects
neutral when the car is stationary and the engine idling in drive,
reducing drag on the engine and saving fuel. In hot conditions it
selects a lower gear to run the engine and air conditioning pump
faster to cool down the cabin quickly. In cold conditions it runs
the engine faster to reduce warm-up time and emissions.
The 8HP70 offers performance benefits too. Taking just 200
milliseconds to complete the entire shift event, the 8HP70 gears
change with an imperceptible interruption of torque for smoothness
equalling that of a dual-clutch transmission, while providing a
more sophisticated driving experience. The 8HP70 matches the engine
speed to its turbine speed in anticipation of oncoming downshifts
for an absolutely smooth transition from one ratio to the next.
Closer ratios also contribute to making individual shifts
smoother.
Driver Type Detection monitors driver inputs and the car's
systems to optimise the response of the gearbox to the driver's
style, while Curve Detection makes sure the gearbox avoids unwanted
upshifts and holds on to the same gear when taking a sequence of
bends. The gearbox also monitors the driver's use of the brake
together with the rate of deceleration to set up the correct gear
for entry and exit to the corner. The 8HP70 does not have to change
to a lower gear sequentially and can skip up to six ratios if
necessary, for much faster response when preparing to overtake.
Driver controls include steering wheel paddles as standard
enabling the driver to take control of gear shifting manually. The
rotary switch selects park, reverse, neutral, drive or sport modes,
the last of these optimising the gearbox response times for maximum
acceleration, improved response and sharper upshifts.
Advanced V8 engine combines high performance with
efficiency
The astonishing 5.0 LR-V8 naturally aspirated engine is a
lightweight aluminium alloy engine which is both super-efficient
and compliant with the stringent US ULEV2 and European EU5
emissions regulations.
The 5.0 LR-V8 produces 276kW and 510Nm torque with low CO2
emissions of 328g/km. One of the secrets of the V8's efficiency is
the centrally-mounted, multi-hole, spray-guided fuel injection
system delivering 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 number of clever 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. Cam profile
switching (CPS) selects either a profile suitable for low speed
running or another which gives increased lift for high performance.
This provides the Discovery 4 with exceptional low-end torque to
negotiate demanding terrain and allows it to become fleet of foot
when conditions allow.
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 is 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.
Superb 6-speed automatic transmission
The LR-V8 drives through the ultra-refined ZF 6HP28 6-speed
automatic transmission. Its characteristics have been optimized by
Land Rover engineers to provide the same class-leading response,
with rapid and refined shifts. The superior power and torque
characteristics of the engine make it possible to actuate the
transmission's lock-up clutches much earlier in each gear, reducing
slip through the hydraulic torque converter, optimizing both fuel
consumption and CO2 emissions.
On- and off-road breadth of capability
The Discovery 4 suspension system is widely acknowledged as being
the most versatile ever developed for both on-road and off-road
use. A variable ratio steering rack gives greater stability during
high speed cruising and increased sensitivity at acute steering
angles. Powerful brakes comprise twin-piston sliding callipers with
360mm ventilated discs at the front and single piston with 350mm
ventilated discs at the rear. The understeer control system
intervenes by automatically slowing the vehicle to bring it back
under driver control.
Land Rover's acclaimed Terrain Response® system
includes a setting for general driving; grass, gravel, snow; mud
and ruts; sand; and rock crawl. Two additional features were added
in 2011: Hill Start Assist which automatically retains the
driver-generated brake pressure when the driver's foot moves from
brake to throttle without the car rolling backwards; and Gradient
Acceleration Control, 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.
e_TERRAIN TECHNOLOGIES boost economy and lower CO2
emissions
The new Discovery 4 is packed with features aimed at reducing fuel
consumption and reducing CO2 emissions. Both the 183kW and 155kW
versions of the 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 LR-V8's high pressure, spray guided direct injection system
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.
Engines have also been optimised for low-end torque as well as
economy, making it possible to activate the lock-up clutch of the
automatic transmissions 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 Discovery incorporates several other energy saving features
too. At standstill, the idle speed of the 3.0 LR-TDV6 is a low
710rpm and the LR-V8, 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.
