Audi has introduced its ultra-efficient FSI petrol engine in entry-level models in the A6 range.

The A6 2.0 T FSI saloon is available to order for £24,340 and the Avant for £25,910 on-the-road. Deliveries begin in July.

Each variant is powered by the first four-cylinder petrol engine in the A6 range, the 2.0 T FSI providing a 0-62mph time of 8.4 secs (Avant 8.7 secs), max speed 141mph (Avant 138mph), a combined mpg of 34.4 and carbon dioxide emissions of 197g/km.

Audi describes the FSI-powered models as the ‘most cost-effective petrol executive model in the premium sector’.

The cars are available in SE and sporting S line trim.
