Audi is adding a plug-in hybrid powertrain to its A8 luxury saloon, as part of the brand’s new range of low-emission electrified vehicles.

The A8 60 TFSI e is the third new plug-in hybrid model to go one sale, following the recent launch of the Q5 TFSI e and A7 Sportback TFSI e. By next year there will be a strong line-up of models to utilise the technology, including the A3 and A6.

Being the flagship of the line-up, the A8 packs a significant punch thanks to a 3.0-litre turbocharged V6 petrol engine. With the addition of an electric motor, the powertrain delivers 449PS and 700Nm.

The car is able to over almost 29 miles (WLTP) on electric power when fully charged and the hybrid system helps reduce CO2 output to between 57 and 61g/km.

A 14.1kWh battery is positioned under the boot floor and allows the A8 to travel at up to 83mph in EV mode.

The A8 plug-in hybrid will be available in standard or long wheelbase and all versions get Quattro all-wheel-drive.

Pricing data is yet to be published, but should be available before the end of the year when the car officially goes on sale. First deliveries for both variants will commence soon after in early 2020.

 “A luxury car is not only defined by the quality of its materials and finish – a sense of calm, comfort and serenity is also integral to the overall experience,” said Andrew Doyle, director of Audi UK. “Which is why, with its near-silent, emissions-free driving mode, the A8 TFSI e raises the bar even higher in terms of refinement, even by the exceptional standards already set by the more familiar versions. It is a highly appropriate new addition to the A8 model line which makes perfect sense whichever way you look at it.”
