This is the updated Range Rover, which goes on sale in September with a new V8 diesel engine, new eight-speed automatic gearbox, and additional driver aids.
The face-lifted car is the first Range Rover to achieve an average of more than 30mpg, although only just at 30.1mpg.
It's all thanks to the new eight-speed automatic transmission and 309bhp 4.4-litre twin-turbo V8 diesel engine, which replaces the 268bhp 3.6-litre engine and delivers nearly 5mpg more on average. Emissions also drop from 294g/km to 253g/km.
That doesn't mean a cut in company car tax, but it does mean slightly lower road tax, which falls from 435 to 425 (or from 1385 to 1175 in the first year with the new 'showroom tax').
Although it's more efficient, the new engine makes the Range Rover much quicker. With 41bhp more than the 3.6-litre engine, it cuts the 0-60mph time from 8.6 seconds to 7.5 seconds. Top speed increases from 125mph to 130mph.
The 5.0-litre supercharged V8 petrol engine is unchanged, although all cars get a pair of new 'Terrain Response' driver aids. Hill Start Assist keeps the brakes applied long enough for the driver to move to the accelerator pedal without the car rolling back, and Gradient Acceleration Control prevents the car speeding up on severe gradients even when Hill Descent Control isn't engaged.
