Land Rover’s large cars have all received makeovers for 2010. Range Rover was first in July with a supercharged 5.0 litre replacement for the 4.2 V8 petrol unit from Ford’s South Wales engine plant.

For September, the Range Rover Sport inherits the same Jaguar Land Rover 5.0-litre and similar interior and technology refinements. For the Discovery things go further and ‘3’ has become ‘4’.

Three key aspects, according to Land Rover, justify the new ‘name’: a TDV6 3.0 litre twin turbo diesel engine; improved on-road behaviour; fresh design features – inside and out.
