Audi is aiming to have three electric car models by 2020 and for electric vehicles to account for 25-20% of its sales by 2025, according to a report in a German newspaper.

Audi chief Rupert Stadler told daily Heilbronner Stimme that Audi's offering of electric cars would also include small vehicles in the A-segment.

Reuters has reported that Audi's electric car strategy is part of an overhaul to strategy following the 'dieselgate' crisis for VW Group.

In a shift of strategy, the VW Group will focus more resources on electric cars, digital services and autonomous driving.

Audi also plans to set up a subsidiary, to be called SDS Company, to develop an autonomous car.

"This is about a robot car that may not even need a steering wheel or pedals, so it's ideal for urban traffic," Stadler said. He also said that Audi is still looking for joint venture partners who would help with the advanced technologies.

In return for stepping up its focus on electric vehicles, autonomous driving and digital services, Audi will seek to reduce complexity in other areas, Stadler told the newspaper.

"We have discussed what would happen if we dropped the two-door version of the A3. I think we would barely lose any customers. We'd rather invest the money that is freed up in new models and other derivatives," Stadler said.

VW Group set out a new long-term strategy last month, including a move towards greater electrification.The company said it plans 30 new e-vehicles by 2025, across the group's brands.
