The new Audi A3 now offers a reworked 1.2-litre TFSI engine with 105 PS and 57.6 mpg capability.

Helped by Audi ultra-lightweight construction technology, the all-new A3 equipped with this engine can cover up to six more miles per gallon than its predecessor, regardless of whether it is equipped with the six-speed manual gearbox or optional seven-speed S tronic twin-clutch transmission.

The six-speed manual version reaches 62 mph from rest 0.7 seconds quicker than its predecessor at 10.3 seconds without compromising efficiency - CO2 output is now 13g/km less than before at 114 g/km.

The efficiency savings have been achieved thanks to a start-stop system and energy recuperation, as well as numerous optimisation measures.

Customers can choose the A3 1.2 TFSI in SE, Sport and S line specification.

Standard equipment common to all includes alloy wheels, air conditioning or climate control, the Audi Music Interface (AMI) linked to an electrically retracting colour MMI display screen, Bluetooth connectivity, a Driver's Information System and preparation for SD card-based satellite navigation.

Sport models include larger alloy wheels, front sports seats, sports suspension, the Audi drive select adaptive dynamics system, additional aluminium interior elements and chrome body detailing.

The highest specification S line models benefit from 18-inch partly polished alloy wheels, Xenon Plus headlights with LED-daytime running lights, Biathlon cloth and leather upholstery with S line embossing and contrasting silver stitching, matt brushed aluminium inlays and a flat-bottomed S line steering wheel.

Prices start from £17,905 OTR for the A3 1.2 TFSI with six-speed manual transmission in SE specification and rise to £22,760 OTR for the range-topping S line model with optional S tronic twin-clutch transmission.

Ordering is possible now for three-door versions, and will become available for five-door Sportback versions in the summer.

First deliveries of three-door versions will begin in May.
