A new three-cylinder petrol engine has joined the updated Audi A1 range, bringing emissions for the petrol model below 100g/km for the first time.

The 95PS turbocharged three-cylinder petrol engine effectively replaces the 89PS 1.2-litre four-cylinder engine available in the A1 since launch. 

A seven-speed S tronic twin-clutch transmission is also available.

The new engine can return up to 67.3mpg in the A1 when linked to the standard manual gearbox, or 64.2mpg in conjunction with the S tronic transmission, equating to CO2 figures of 97g/km and 102g/km respectively. These figures apply regardless of the body style chosen.

The new three-cylinder petrol engine is available in conjunction with either SE or Sport specification, both options including alloy wheels, remote central locking, air conditioning, electric front windows and mirrors and a six-speaker single CD audio system with auxiliary iPod connection linked to a 6.5-inch retractable display.

A secondary collision brake assist system, which can initiate automatic braking to reduce the risks of skidding and additional collisions during an accident, also now forms part of the standard equipment list.

The model starts from £14,315.
