The Audi A3 Sportback has been on sale for a while now and the Audi A5 Sportback is due to hit Audi dealerships in September, but sales have already begun, for Audi contract hire and Audi Leasing options contact Audi Nationwide.

The Audi A5 Sportback joins the Coupé and Cabriolets models to complete the Audi A5 family, for now. Could we see an Audi A5 Avant in years to come? I believe that is a question not even Audi has an answer too.

So for now, let’s have a closer look of what the Audi A5 Sportback has to offer. First, all six engines are highly efficient direct injection and are equipped with Audi’s exclusive energy recuperation system, this combination helps all 6 engines comply with the Euro 5 emissions standards which could save you money with your company car tax. Out of the 6 engines available, only the 2.0 TDI and the 2.0 FSI come with Audi Start/Stop technology.

As mentioned above, the Audi A5 Sportback reinforces Audi’s leadership in innovative automotive design. With a combination of elegance with flowing stretched lines and progressive styling the A5 Sportback impose a powerful figure on the road.

Fourtitude describes the Audi A5 Sportback with perfection:

“A five-door model with the long, flowing rear end unites the best of various vehicle genres: the emotion and elegance of a coupe, the comfort of a sedan and the practicality of a station wagon.”

The model is based on the A5 coupe, but has a more practical five-door body. Audi says it’s ‘as emotional and elegant as a coupe, as comfortable as a sedan and as practical as an Avant’.

It has a coupe-style roofline and rear end design, but Audi promises a 480-litre boot and 980 litres of load space with the rear seats folded, according to What Car?

Despite a lower height than the A4 saloon, Audi says the A5 Sportback has comparable head- and legroom.

Five engines will be on offer from launch: 2.0 TFSI and 3.2 V6 petrols and 2.0 TDI, 2.7 TDI and 3.0 V6 TDI diesels.

The 3.2 and 3.0 TDI V6s both come with four-wheel drive and the 2.0 TDI has a stop-start system to save fuel.

A further entry-level model will follow in 2010.

The new 5-door coupe will debut at the Frankfurt Motor Show and be available from September 2009.
