Volkswagen is adding a new range-topping R version to the Touareg line-up, featuring a plug-in hybrid powertrain.

The brand says it can cover “typical commuter distances” with zero-emissions, thanks to a 14.1kWh battery.

A gearbox-mounted electric motor combines with the car’s turbocharged V6 petrol engine to produce a maximum output of 462PS and 700Nm. Power from either the engine, electric motor or both can be directed to the wheels rapidly, via an eight-speed automatic transmission.

The car can reach speeds in excess of 85mph using just the electric motor, which feeds power to all four wheels.

Whenever route guidance is active in the navigation system, the battery manager predictively takes into account road and topographical data to ensure the set battery energy is available when the driver reaches their destination. During this process, battery use is adapted on the basis of the route data in order to achieve an optimum electric range.

Joining the flagship R line-up, the new Touareg R benefits from a sporty makeover with more aggressive bumpers and 20-inch alloy wheels.

Fuel economy, pricing and CO2 emissions have not been confirmed, but it’s likely the Touareg R will be the most company car tax efficient model in the range.

The powertrain is borrowed from the Porsche Cayenne E-hybrid, which offers the same power output. That car emits 70g/km of CO2 and manages 70mpg.

The Touareg is also available with a V6 TSI, V6 TDI and V8 TDI.
