Is it the 1980s again? First Mercedes-Benz returned to the inline-6 configuration with their M256 engine and now Land Rover are as well.
Their latest Range Rover Sport HST model will be the first to introduce this inline-6 petrol engine from the Ingenium family of motors. With its 400PS, 550Nm output, it’s expected to move the Range Rover Sport from 0-100km/g in just 6.2 seconds.
But it’s not just any old inline-6 engine. Just like the M256 by Mercedes-Benz, this Land Rover unit comes with an electric compressor and a mild-hybrid system to eliminate the disadvantages of the engine’s twin-scroll turbocharger.
Electric Supercharger
This electric compressor spools up from idle to 120,000rpm in half a second. Its main purpose is to eliminate turbo lag. It uses a direct connection to throttle input to work out when to engage.
Mild Hybrid System
Land Rover calls this their “Mild Hybrid Electric Vehicle” powertrain. It is used primarily to power the vehicle’s electronic systems and to help the car get moving from a standing start, where petrol is most inefficiently used.
The system recovers energy from braking and keeps it in a 48V battery. The system allows the car’s systems to function as though the engine is operational even when the Start-Stop system cuts it off.
