First JLR mild hybrid on sale is 3.0-litre straight-six Ingenium petrol engine making 395bhp, and is only available in special edition trim
13 February 2019

Land Rover has added a new straight-six mild hybrid Ingenium petrol engine to the Range Rover Sport line-up, debuting first in a special edition model.

The Range Rover Sport HST, priced from £81,250, uses a 395bhp in-line six that replaces the old V6 petrol. It’s said to offer more performance and greater refinement, while at the same time improving fuel economy and emissions.

The unit features an electric supercharger, able to spool up to 120,000rpm in half a second to, the firm claims, “virtually eliminate” lag from the twin-scroll turbocharger. The motor itself produces 406lb ft of peak torque.

It’s also the first Jaguar Land Rover production model to on sale with a mild-hybrid system, as part of the firm’s plan to offer an electrified variant on every model launched from 2020. The recently revealed Evoque also features the tech, but it's not yet on sale.

The 48v system harvests energy through regenerative braking, storing it in a small battery that can offer electrical assistance when pulling away, while allowing longer stop/start activation.

The new engine makes the Range Rover Sport HST capable of 0-60mph in 5.9 seconds, while going on to a top speed of 140mph. Fuel economy is rated at 30.5mpg, with CO2 emissions of 213g/km, under the old NEDC measuring regime. 

Like the current range of four-cylinder Ingenium engines, the new straight-six has been designed and developed in-house and will be built at JLR’s Wolverhampton engine facility

The HST special edition also brings with it unique combinations of exterior and interior upgrades, including carbon fibre trim, red brake callipers, and ‘suede cloth’ detailing on the wheel and gear lever.

Sounds creamy but the fuel consumption sounds crummy. Nearest comparison is the 53 AMG mild hybrid which - on paper - seems a lot more efficient.

JLR’s engine tech is holding them back.

Scrap - You cannot comment on fuel economy until you have actually driven the vehicle and determined what the mpg really is, when you use it. I drove a manual BMW 118i recently for 700 miles. The trip computer said that the fuel economy was 42mpg. In reality it was 49. The majority of the mileage was on the motorway, at the legal limit or at 50mph in the roadworks, and on A roads. I hardly overtook anyone, and I used the eco-pro setting and the suggested gear at all times. I never used the A/C. I drove with no more than 1 passenger and not much luggage. The BMW is a small and relatively light vehicle, the engine is a new 1.5 3 cylinder petrol unit.  

Therefore if I could get 30mpg from a 3 litre petrol, much larger, much heavier, brick of a RR Sport, on the same journey, I would be very happy.

I meant to say, the BMW fuel economy was 39, not 49mpg

Seems low for a 118i. Getting almost that on much less favourable runs in a 228i

You're quibbling about 3 mpg difference...? I'd count that as a win.

Quite.

The WLTP economy figure is much closer to real world driving than the old NEDC figures - the drive cycle it uses is massively more aggressive.

Still however, the figures take into account all types of driving - the average being on the lighter side.

Aggressive drivers will never achieve the stated MPG figure, light-footed drivers who utilise the eco gear suggestions and drive at optimum speeds (50-60mph in top gear) will achieve, or improve on the stated figure.

The old supercharged V6 was 55bhp less powerful, barely capable of 28mpg, and emitted 243g/km of CO2 under the older, less stringent NEDC tests.

ON PAPER, not in reality.

I just want to congratulate JLR for finally getting the Ingenium six into production.  Great news, and well done to all involved!

 If your prepared to hand over £80K+ your not going to be that bothered about how far it goes on a Gallon, most are bought because your supposed to have one, because it’s supposed to be the best......
