LRX - Concept Car
Land Rover reveals an exciting vision of its future with the LRX concept – a bold evolution of Land Rover design that signals the brand’s shift into new areas of the market, while remaining true to its core values. As the company prepares to celebrate its 60th anniversary during 2008, the three-door LRX, with its more compact size, lighter weight and sustainability-focused technologies, clearly addresses the needs of a changing world and offers the potential of 120 g/km CO2 emissions.
COMPACT AND PREMIUM
LRX is described as a cross-coupé and dramatically extends the scope of what Land Rover represents. Though 149 mm (5.9 in) shorter than the Freelander 2 / LR2 and 205 mm lower, LRX was conceived as a premium car, designed to appeal to new customers in the luxury and executive sector – those who want many of the benefits of a 4x4 and the presence of a larger vehicle, but in a more compact package.
Its compact size is one of its greatest assets, which will appeal to anyone who wants the versatile ability of an agile 4x4 with the cachet of the Land Rover name. In addition, its lower weight and the reduced aerodynamic drag resulting from the smaller frontal area would help give significant gains in fuel efficiency and reduced CO2 emissions.
HIGHLY EFFICIENT POWERTRAIN
LRX is conceived as a highly fuel-efficient, 2.0-litre, turbodiesel hybrid, capable of running on bio-diesel. In combination with other Land Rover technologies, this powertrain could reduce fuel consumption by as much as 30% compared with other 4x4s of comparable size, and reduce emissions to approximately 120 g/km.
LRX’s improved efficiencies are the result of advanced mechanical and electrical energy-saving elements, which are combined to achieve cumulative gains in many areas.
The concept’s integrated Electric Rear Axle Drive (ERAD) is particularly significant in Land Rover terms as it would allow LRX to use electric drive alone at lower speeds while retaining full (even improved) 4x4 ability in tough conditions. Unlike the hybrid technology used by some 4x4 rivals, Land Rover’s unique solution retains mechanical drive to all four wheels.
Off-road, the ERAD would provide additional torque only when it is needed, and with maximum electrical torque from standstill, this solution offers even better low-speed control and enhanced pull-away on difficult surfaces (such as packed snow or wet grass) or when towing.
On the road, the ERAD would allow low-speed traffic creep up to 20 mph (32 km/h) on electric power alone, with the Integrated Starter-Generator (ISG) function re-starting the engine automatically when needed. The electric drive would then continue to assist the mechanical drive until the engine is running in its most efficient range, benefiting both fuel consumption and CO2 emissions.
The ISG would also stop the engine automatically when the vehicle halts in traffic, so the engine does not idle needlessly, and restart it quickly and smoothly as required.
The electrical drive system uses power stored in a dedicated high-voltage, high-capacity, lithium-ion battery pack, independent of the normal 12-volt battery. This is charged by a regenerative braking energy system, also working through the ERAD.
SUSTAINABLE PRODUCT DESIGN
The exposed structures of the seats, roof and instrument panel are just one novel approach that Land Rover’s designers have taken to reduce vehicle weight. Another example is replacing the glass for the side windows and roof with polycarbonate from SABIC Innovative Plastics, which is around 40% lighter. The polycarbonate also blocks virtually all UV light (protecting interior materials from fading), while special nano-technology within the material reduces infra-red transmission, helping to keep the interior cool.
Even the choice of premium-quality trim materials reflects Land Rover’s deep thinking about sustainability, with vegetable-tanned leather (chromium-free, so better for recycling), extensive use of aluminium (both lightweight and readily recyclable) and carpeting made of felt from sustainable sources. And the luxurious, vanilla-coloured ‘fine suede’ on the door inserts and headliner is a 100% recycled material made from used plastic bottles and fibres.
“We are determined to make sustainability a key element in our future product design and the way we do business, while still creating vehicles that have a strong emotional appeal as well as fulfilling people’s practical needs,” says Phil Popham. “No single technology delivers all the answers to whole-life sustainability, but the LRX concept brings together some of the ideas for the future that interest us, integrating them into a car that we believe represents an exciting way forward for Land Rover.”
