When it comes to fuel economy you’ll do better with the diesels than the petrols. Official figures say you’ll get up to 33mpg from the entry-level D300, while the P400 petrol engine promises up to 26.7mpg.
If you embrace the powerful performance models, then that figure will drop; the 565hp P565 promises just 18.9mpg. Versions like the SV Autobiography range, are powered by a supercharged, 5.0-litre V8 engine with 565hp so fuel economy is traded of for power.
All that said, you could get excellent fuel economy from the P400e plug-in hybrid, as long as your journeys are mainly short and done on battery power alone. The official figure claims up to 84.8mpg, but to achieve such a return from the Range Rover then you’d need to regularly charge it and do most of your journeys on electric power alone.
