The Audi A1 and Audi A3 are now available with a 1.4-litre petrol engine that features cylinder-on-demand fuel-saving technology.

The 138bhp four-cylinder petrol engine deactivates two cylinders (when driving under light loads, such as periods of motorway cruising) to improve fuel economy. It is the same engine as in the Volkswagen Golf.

It is available in the A1, A1 Sportback, A3 and A3 Sportback. The A1 models come with a seven-speed S tronic semi-automatic transmission and the A3 models get a six-speed manual.

The A1 gets from 0-62mph in 7.9 seconds, while the A1 Sportback takes 8.0 seconds. The A3 completes the 0-62mph dash in 8.3 seconds, with the Sportback marginally slower at 8.4 seconds. All cars have a top speed of 132mph.

Average economy for the A1 and A1 Sportback in Sport trim is 60.1mpg, with CO2 emissions of 109g/km. S line and Black Editions of the A1 Sportback return average economy of 57.6mpg and CO2 emissions of 113g/km.

The A3 does 60.1mpg and emits 109g/km of CO2, while the Sportback does 58.9mpg with emissions of 112g/km.
