Frankfurt motor show: Audi S5 Sportback

Audi has officialy launched its new S5 Sportback at the Frankfurt motor show today.

The hot Audi S5 Sportback will enter production in Spring 2010, the company has confirmed.

Using the same 328bhp supercharged V6 as the S4 saloon, the S5 Sportback also gets quattro permanent four-wheel drive and a seven-speed twin-clutch S-tronic gearbox as standard.

Audi’s Sport differential, which actively distributes drive between the car's rear wheels, will be offered as an option.

Audi says the S5 Sportback should crack 62mph in 5.4sec, and go on to a governed 155mph maximum speed. It will be shown at next month’s Frankfurt motor show, enter production in spring 2010 and come to the UK next summer.

The S5 Sportback will share Audi’s Frankfurt motor show stand with two other production car debutants: a Euro6-compliant ‘clean diesel’ version of the A4 saloon, and a 103bhp 1.2-litre TFSI version of the A3 capable of 51.3mpg.

The ‘clean diesel’ A4 features a 3.0-litre V6 diesel motor with a revised common-rail injection system, new pressure sensors within the combustion chambers and a high-performance exhaust gas recirculation system which combine to make the combustion process more efficient.

It also has a DeNOX catalytic converter to reduce emissions of nitrogen oxides. It allows the A4 to return 42.2mpg on the combined cycle.

Audi’s 1.2-litre turbocharged A3 will trump the bigger A4 with its green credentials, however; it's capable of 51.3mpg, and emits just 127g/km of carbon dioxide.

Its downsized engine has direct injection as well as forced induction, and produces 103bhp and 129lb ft of torque between 1500rpm and 3500rpm.
