The 3.0-liter straight six cylinder gasoline engine, which will debut on the Range Rover Sport, is available in 360PS and 400PS versions with torque capability of up to 495 and 550 N·m, is more responsive and better balanced than the outgoing V6 gasoline engine. Rover says that the supercharger can spool fully in 0.5 seconds.

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 power is stored in a 48V battery and can then be used to improve the engine's efficiency when it is under load, such as when pulling away from traffic lights.

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.

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.

The manufacturing giant said the "mild" hybrid electric engine system will help reduce emissions as well as optimise performance and fuel economy.

This is the latest step Land Rover has taken towards meeting its commitment of offering an electrified option on all new models from 2020.

Unlike the inline-4, the new inline-6 features a 48-volt electrical system that gathers energy during braking.

Nick Rogers, executive director of product engineering at Jaguar Land Rover, said the new engine would also be more refined than the old V6 thanks to its in-line layout.

Buyers of the Range Rover Sport HST will also get a carbon-fiber trimmed exterior, red brake calipers, special badges, and updated color patterns for the interior. There's a choice of five exterior colours, too, including Santorini Black, Fuji White, Indus Silver, Firenze Red and Carpathian Grey. Satin Chrome gear shift paddles flank a steering wheel trimmed in suede and HST badges are also present inside.

Safety enhancements include Advanced Cruise control with steer assist and Stop & Go.
