New Range Rover Sport HST Has A Straight-Six Mild Hybrid With 395hp

This is the new Range Rover Sport HST, the first production vehicle from Jaguar Land Rover to launch with a mild-hybrid powertrain.

Powering the Range Rover Sport HST is the all-new 3.0-liter inline-six cylinder gaasoline engine that boasts 395 hp and 405 lb-ft (550 Nm) of torque. The engine replaces the company’s V6 petrol and is special due to its implementation of an electric supercharger and a twin-scroll turbocharger.

Jaguar Land Rover says the electric supercharger is driven directly by an electric motor that can spool it up to 120,000 rpm in half a second. The presence of this electric supercharger is said to virtually eliminate all lag from the turbocharger. The new engine also reduces CO2 emissions over the petrol V6 by 12 per cent while cutting down on particulate emissions by 75 per cent.

In addition to the electric supercharger and efficient turbocharger, the Sport HST’s powertrain includes Continuous Variable Valve Lift (CVVL), a system that varies inlet valve timing and lift profile to improve efficiency. There is also a 48-volt system that can harvest energy on the move, provide torque assistance to the engine, and trigger the Start-Stop system.

The SUV has claimed fuel economy figures of 30.5 mpg (9.3 liters/100 km) combined and CO2 emissions of 213g/km.

“In-line six-cylinder engines are inherently better balanced than V6 designs and our all-new Ingenium unit builds on that promise to optimize efficiency in all operating conditions. Advanced features, including an electric supercharger, ensure distinctive Range Rover Sport performance and responses, while the intelligent MHEV system harvests energy to improve fuel economy and reduce emissions,” Jaguar Land Rover executive director of product engineering Nick Rogers said.

As for the Range Rover Sport HSE itself, it will be sold as a special edition and can be distinguished from other models with unique badging and carbon fiber trim across the exterior. Inside, Land Rover has equipped the vehicle with 16-way Dynamic front seats with red and black leather and satin chrome shift paddles. The vehicle also includes Advanced Cruise Control, High Speed Emergency Braking, and Land Rover’s Terrain Response 2.

The Range Rover Sport HST will set UK customers back £81,250 ($104,733). It remains to be seen if the car will be sold elsewhere.

    WOW what a wonderful surprise.


  • SteersUright

    I’d love to see Land Rover return to boxier, more safari-esque design, significantly improve reliability & build quality, and thrive. This is such a storied brand, it’d be a shame if they don’t make it over the years.

    • Astonman

      The Defender should do that for you. I love the looks of the line right now. My issue is the quality issue I keep reading about and have had friends deal with them. That issue is what’s holding me back.

      • Merc1

        Losing 4.4B last quarter they have to get the Defender right. I hope they do because Land Rover deserves to live because they are very unique in the market.


        • Astonman

          They took a write off of 4.4B but did not lose that much. Another person on this site explained it really well. Regardless of the amount, I hope the best for them also. In general I tend to hope the best for all brands. I’m a car enthusiast first and company guy second. There is enough business for everyone.

          Especially in a marketplace that is currently in love with Jeeps, Raptors, etc. How could they not see the potential?

      • SteersUright

        I certainly hope so but, it isnt looking promising. The spy shots and renderings are showing an ugly, theme park caricature of what the Defender should look like. Hopefully, I’m wrong and it looks properly tough when it comes out.
        Then again, I also think MB mostly got the new G-wagen wrong too. It looks like a Russian tuner version with its party-time LED strip headlights and the sheer amount of bling and disco lighting inside. To each their own…

        • Astonman

          I think they’re doing a fantastic job disguising the looks of the Defender. It is way too obvious that it looks like the old LR3 that it can can’t be true. It doesn’t make sense to design something new to look like something that was cancelled 2 years ago. You may not be happy with the final design but it won’t be anything like what you’re seeing now.

    • Merc1

      That about design is why the new Discovery isn’t having an easy time on the market. The neutered the design too much by making it all sleek and pretty vs the boxy, stepped roof of the previous model (LR4). They should have done something in between the old one and the what they have now.


      • SteersUright

        Thing is, it isnt pretty either. Its just bland. A Whirlpool refrigerator on wheels, particularly in white. The Range Rover is sleek and pretty, but still a bastardization of what any Land Rover ever was or should be. BMW had it right when they briefly owned the brand. They kept the tough, boxy, off-roader appearance while finally bringing the powertrains to modern standards. Too bad they ever sold it. Unlike Geely Motors with Volvo, Tata has no clue. Its quickly ruining Jaguar and Land Rover.

    love this.

    So what happened to P400e? This one has a bigger IC engine and the end result is less power and much less torque. I doupt it is much cheaper to produce with an electric supercharger so what is the point?
