To help combat turbo lag and provide better response, Land Rover fitted the powertrain with an electric supercharger than can spin up to 120,000 RPM in just half a second.
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.
Right now, Land Rover has only announced the Range Rover Sport HST for the UK, but it shouldn't be long before the company unveils the same trim for US-spec cars.
