Range Rover Sport review: P400 HST kinda-hybrid driven

# data.attributes.metatag[].attributes.content
Range Rover Sport HST? What’s that, a detuned SVR?In a way, yes. It probably is best thought of as a stepping stone between the P400e plug-in hybrid and the full fat 575bhp supercharged V8 SVR. The HST has an eye on both sides. On one side, 395bhp from a turbocharged 3.0-litre, and on the other a 48-volt mild-hybrid system.Can you plug it in?

which uses a 2.0-litre four-cylinder Ingenium petrol engine mated to a 141bhp electric motor that takes power from a 13.1kwh battery. It can drive exclusively on electric and has lovely low CO2 emissions. It’s the Range Rover Sport for the concerned urbanite. The HST can’t be plugged in nor run exclusively on electric power.Does it feel electric at all?It feels… different. Here’s what’s going on: the engine is a brand new 3.0-litre straight six Ingenium that has quite a lot in common with the four-cylinder in the P400e. I know

Although 2,310kg doesn’t sound so much in the era of electric cars, when smaller Audi e-trons and Merc EQCs are nearly 2,500kg.

Really rather pleasant. It’s smooth and makes a lovely noise. Not nearly as obnoxious as the bellowing SVR, but a more inwardly focused growl that you’ll notice and appreciate.

Way better than an SVR. Miles and miles. An SVR typically does about 17mpg, whereas the HST manages 27mpg. That might not sound great, but when we ran a Discovery 5 TDV6 a couple of years back, that would barely scrape 30mpg, so the fact a 395bhp petrol is in that ballpark shows the technology works. In my head a 395bhp six-cylinder turbo would be doing 22-23mpg, and this was 5mpg better – so pretty encouraging.

The new WLTP fuel consumption claim is 27.4mpg, but as yet there are no WLTP CO2 figures – instead the old NEDC cycle is 213g/km. Expect that to climb to around 225-230g/km.

Is there anything else new or interesting about the P400 HST?

At the moment it’s only available to special order, which is Range Rover’s way of saying the HST is a toe-in-the-water. The image is more angled to SVR than PHEV: there’s carbonfibre trim on the bonnet, grille, vents and tailgate, plus red brake calipers (although you can choose to have these grey instead).

There are five exterior colours (black, white, silver, red and grey), a choice of two different alloys, while inside there’s a suedecloth steering wheel and gear lever plus other bits of badging and trim to fit the sporting brief. The seats are 16-way adjustable, but overall a bit firmly padded.

And what does it cost?

It’s £81,250. Which puts it on a par with the mid-spec P400e, proving that they’re aimed at very different customers. Personally I rather like this as a package. It’s far less brash than an SVR, feels like a more intelligent, educated choice that doesn’t sacrifice drivability, but does appear to get some fuel economy gains.
