AUDI is to add a plug-in hybrid powertrain to its line up of Q3 SUV models as the German car maker goes about expanding its electrified range.

The new Q3 45 TFSI e will be available to order from spring next year in both standard and Sportback body styles and in four trim levels - Technik, S line, Black Edition and Vorsprung.

The Sportback range will start from the S line model upwards.

Both will have an electric only range of up to 31 miles and will be powered by a 1.4-litre petrol engine mated to an 85kW electric motor.

Together they develop 245ps giving the car a 0 to 60 acceleration time of 7.3 seconds and a maximum of 130mph.

Prices are still to be announced but Audi says the car can be recharged in three hours 45 minutes from a domestic supply.

Boot space is reduced at 380 litres with a maximum amount of space of 1,375 litres in the Q3 model and 1,250 litres in the Sportback - down from 530 litres minimum and 1,525 and 1,400 maximums in the non-hybrid versions.
