New HST version mixes 394 bhp and improved economy. but everything's relative.


Range Rover retrieves its HST trim from the fine china cabinet when it wants to introduce something special.

These performance-boosting technologies work alongside a new Mild Hybrid Electric Vehicle (MHEV) powertrain that is underpinned by the new engine, bringing enhanced efficiency to the range with fuel economy of 9.3 litre/100km.

This allows the system to harvest energy through regenerative braking and store it in a 48V battery for later use, such as when pulling away from a standing start. In addition to providing juice for the electric supercharger, it uses an electric motor to harvest energy under braking, and it should increase the amount of time the stop-start system can stay activated.

The new engine features a combination of an electric supercharger to deliver immediate response supported by a twin scroll turbocharger and Continuous Variable Valve Lift, which boosts power and help the engine to breathe with maximum efficiency.

In total, the system produces 394 bhp, allowing the big 4x4 to sprint from 0-60 miles per hour in less than six seconds and hit a top speed of 140 miles per hour. Throwing a 48-volt mild hybrid in there, too, that's what. It doesn't sound like much of an improvement, but bear in mind that this engine's predecessor - a supercharged V6 from the Jaguar F-Type - was only capable of 26.9 mpg and 243 g/km on the now-defunct and less stringent NEDC economy test. And that's despite the V6 having less power.

The new 3.0-liter turbocharged inline-6 replaces the dated supercharged 3.0-liter V-6 and is part of the Ingenium family of engines The supercharged V-6 suffers from numerous inefficiencies, including the fact that it is actually a V-8 that simply doesn't use two cylinders.

Like every other Range Rover, it's not exactly hard to look at.

Land Rover on Wednesday unveiled the Range Rover Sport HST, a special edition with a new member of Jaguar Land Rover's Ingenium engine family.

Inside, the 16-way Dynamic front seats feature an updated colour pattern with suedecloth detailing on the steering wheel and gear lever, Satin Chrome gear shift paddles and an HST badged facia.
