The new 3.0-litre turbocharged straight-six petrol unit, which will be replacing the venerable 3.0-litre supercharged V6 in Australia's Range Rover line-up, comes paired with a mild hybrid setup that utilises a 48-volt electrical system. The latter supplies power to an electric supercharger which supplements the engine’s twin-scroll turbocharger as well as an electric motor that provides torque-assist for the engine.
According to Land Rover, the electric supercharger is able to deliver an immediate boost by spooling up to 65000rpm in half a second, reducing turbocharger lag and improving engine response.
“The otherwise wasted energy (in braking) is used to power the electric supercharger, which enhances the vehicle’s capability by enhancing the torque curve at low engine speeds for greater responses,” executive director of Product Engineering at Jaguar Land Rover, Nick Rogers, said.
The Australian market will be receiving the full-blown 294kW/550Nm iteration of the Ingenium straight-six engine, 14kW/90Nm more than its supercharged V6 predecessor. The new engine is able to charge from 0-100km/h in 6.3sec whist delivering an NEDC combined claimed fuel consumption figure of 9.3L/100km. That’s a second quicker and nearly 2L/100km more frugal than what the supercharged V6 managed.

Land Rover has also updated the 2020 Range Rover’s list of standard features with the addition of a Sign Post Dimming feature that identifies road signs and controls individual LEDs in the headlight to reduce glare to the driver. A new Smartphone Pack that enables Apple CarPlay and Android Auto mobile device mirroring is also offered.
Australian specifications and pricing for the 2020 Range Rover will be confirmed later this month with deliveries expected to begin in October this year.
