German luxury car maker has a lot to show at the 2013 North American International Automobile Show, the company has put a total three vehicles at its display- 2014 Audi R8, Audi RS5 Cabriolet and the all new RS 7 Sportback. Audi RS 7 Sportback will be launched in the UK in the latter part of 2013 and to compete against the recently unveiled BMW M6 Gran-Coupe.
The all new RS7 Sportback houses the similar 4.0-litre, V8 biturbo petrol engine with cylinder-on-demand technology that does its duty to the brand new RS6 Avant, unveiled recently. It churns out the maximum of 552bhp at 5700rpm with the top speed of 205kmph, and the best part with this engine is its competency to increase the speed on demand to 280kmph or 304kmph.
It also employs advanced cylinder-on-demand technology to ensure that economy holds true to Audi efficiency ambitions, with up to 10.20kmpl possible despite the ferocious pace. Available to order in the summer of 2013 priced in the region of £84,000 OTR, and due in the UK towards the end of the year, the RS 7 Sportback shares its 4.0-litre V8 TFSI engine with the recently announced RS 6 Avant.
This means that with the help of its two turbochargers formidable peak power of 552bhp arrives between 5,700 and 6,700rpm, and peak torque of 700Nm is constantly available between 1,750 and 5,500rpm. The two large twin-scroll turbochargers located, along with the intercooler, inside the ‘V’ of the cylinder banks, produce up to 1.2 bar of boost pressure, helping to generate incredible accelerative force.
The RS-specific engine management and unthrottled intake system also contribute to the engine’s dramatic response, and this is delivered with all the charisma expected of a V8. Switchable flaps in the exhaust system can make the sound even fuller at the touch of a button, and customers seeking an even more dramatic drive can choose a sports exhaust system from the options list.
