Audi has revealed a new variant in the A3 range with the first saloon model.

The covers were taken off the A3 saloon, as well as a high-performance S3 version, at the New York Motor Show.

The new A3 Saloon range becomes available for UK ordering this summer, closely followed by the 300bhp all-wheel-drive S3 saloon.

The car has a sleeker profile than a traditional saloon, and Audi is hoping to compete with the new Mercedes-Benz CLA-Class for sales.

The A3 saloon is 150mm longer than the A3 Sportback and will be available initially with 140bhp 1.4 TFSI and 180bhp 1.8 TFSI petrol engines as well as a 150bhp 2.0 TDI diesel.

The 1.4-litre petrol has cylinder-on-demand technology and can run on two cylinders under light throttle loads or when coasting and offers CO2 emissions of 109g/km with fuel consumption of 60.1mpg on the combined cycle. The diesel has CO2 emissions of 108g/km and fuel consumption of 67.3mpg.

Full UK pricing and specification for all variants will be confirmed nearer to order books opening. The first A3 saloon models will reach UK customers in the autumn of 2013, and the first examples of the S3 saloon in early 2014.
