Range Rover gets all-new straight-six mild hybrid diesel

Published: 15 July 2020

► New mild hybrid diesel added to 2021 range
► Straight-six Ingenium replaces old Ford V6
► Special editions added to the lineup

Land Rover’s luxurious Range Rover flagship receives a nip and tuck for 2021, which sees the arrival of the new straight-six Ingenium diesel to take over where the old Ford-sourced V6 and V8 diesels leave off. They come with a 48v mild hybrid system, and promise improved efficiency and refinement. 

The Range Rover lineup has also gains a new set of of special edition models. The Westminster Edition and SVAutobiography Dynamic Black add luxury, joining the very special Range Rover 50, produced to commemorate the half century of this influential off-roader.

New engine adds refinement and efficiency

The new 3.0-litre mild-hybrid diesel is an addition to the modular Ingeniun family. Like the 2021 Range Rover Sport it's offered with a choice of two power outputs in the UK. The D300 version delivers 296bhp, while the range-topping D350 model puts out 345bhp, joining the existing four-, six-, and V8-cylinder powered Rangies. The new D350 isn't lacking in power, delivering more than the old range-topping V8 diesel.

According to Land Rover the D300 Ingenium mild-hybrid diesel engine is considerably more economical than before, averaging upto 33mpg in WLTP testing, with the D350 variant almost matches it with a combined average of 30.8mpg. The 48v mild hybrid has a lower emissions figure than the old V8 – hardly surprising – with an improvement of 37g/km in CO2 output, falling to 238g/km.


It does leave us asking the question – where are the electric Range Rovers? Land Rover remains tight lipped on this one, refusing point blank even to hint about when they're coming. But with the Jaguar I-Pace flying the flag, it can't be long before the bigger selling Land Rover lineup is electrified.

In detail: tech details of the new JLR straight-six

The new 3.0-litre D300 and D350 have 48v mild hybrid tech, an electronic supercharger and is RDE2 certified giving a decent tax advantage for company users. Power outputs of the new mild hybrid Range Rover is between 296 and 345bhp (D300 and D350).

Performance for the entry-level D300 engine is improved over what came before. The Range Rover dispatches the 0–62mph dash in 7.4 seconds, and the D350 cuts that to 6.9 seconds – also an improvement.  

The full engine range now looks like this:

  • D300 296bhp, 3.0-litre six cylinder diesel MHEV
  • D350 345bhp 3.0-litre six-cylinder diesel MHEV
  • P400 390bhp, 3.0-litre six-cylinder MHEV
  • P400e 396bhp 2.0-litre four-cylinder PHEV
  • P525 517bhp 5.0-litre V8 Supercharged
  • P565 556bhp 5.0-litre V8 Supercharged

What about those new special editions?

The 2021 update isn't just about the introduction of a new engine. The Westminster editions and SVAutobiography Dynamic Black join the new Range Rover Fifty limited edition – widening the choice of the aging L405 Rangie.

The infotainment system gets a much-needed update, with Apple CarPlay and Android Auto as standard and passengers benefit from an all-new wifi hotspot set-up with support for up to eight devices. There's an upgraded cabin filtration system, which can clear the cabin of all particulates measuring less than 2.5 micrometres.
