It’s been four years since the fourth-gen ‘new’ Range Rover was revealed. Now, the all-aluminium stalwart of off-road luxury has been fettled for 2017 to keep it feeling fresh.

The big news is a new model, the ‘SVAutobiography Dynamic’. It’s the most powerful Range Rover ever thanks to the addition of the raucous 542bhp, 5.0-litre supercharged V8 petrol engine connected to ZF’s eight-speed automatic ‘box, as seen (and heard) in the Range Rover SVR and Jaguar’s F-Type.

With all that power and 502lb-ft of torque on tap, the near two and a half tonne SUV will go from 0-60mph in 5.1 seconds and on to a top speed of 140mph.

The SVA D (yes, this new nomenclature is getting rather confusing) is only available in standard wheelbase, unlike the bigger, more expensive and luxurious Range Rover SVAutobiography where 80 per cent of buyers have opted for long-wheelbase spec. However, this one is meant to be racier. Hence the ‘Dynamic’ part of the name.

How do you add dynamism? With the help of JLR’s skunkworks SVO division that’s tweaked the suspension with revised knuckles, links, springs and dampers while also chopping the ride height down by 8mm. They’ve also added ‘Dynamic Response’, a clever system that reduces cumbersome body roll by controlling the front and rear axles separately and monitoring how the car is reacting to driver inputs and changes in the road surface to beef up the suspension when needed to be more agile.

Oh, and the Brembo brake calipers can now be painted red for the first time. That’ll definitely chop your lap times down dramatically.

Aside from the side vents, grille, front bumper, and Range Rover badging being finished in a dark ‘Graphite Atlas’ grey and some bazooka quad pipes, visually there’s no difference to a normal Range Rover. There is however, some new tech. There’s a semi-autonomous driving mode and the adaptive cruise control now can recognise traffic signs, and slows your speed down automatically through that zone.

There’s also launch control, but not as you know it. It’s a ‘Low traction launch’ and probably the slowest launch control in the world that helps get you out of boggy or slippery situations by managing the torque more effectively than simply mashing down your right foot.

If the big V8 is too much for you, Range Rover now has another engine option – the 3.0-litre supercharged V6 engine from the F-Type. With 340 bhp and 332 lb-ft, it’ll see the 0-60 mph sprint off in 7.1 seconds. We’re just crossing our fingers it sounds as good as it does in the F-Type.

It’ll cost £132,800 when it goes on sale later this winter – which is nearly double the base TDV6 Rangie and puts it in the firing line of the Porsche Cayenne Turbo S. Your choice?
