FASTER, more economical and better equipped, the second generation of Audi's sleek RS 5 Coupe has been given its world premiere at the Geneva International Motor Show.

When it hits British roads in the summer it will come with cutting-edge driver assistance and connectivity systems and a brand new 450PS, 2.9 litre V6 bi-turbo engine which gives the new model a sub-four second 0-60mph sprint time and a top speed of 155mph.

And if that's not quick enough for you, the car's max speed can be increased to 174mph with an optional dynamic package.

According to official figures, the V6 biturbo is capable of up to 32.5mpg on the combined cycle, emitting 197grams of CO per km - an efficiency gain of 17 percent over the previous model.

Another factor in the greater efficiency of the new RS 5 Coupé is its significantly lower weight. It tips the scales at 1,655 kilograms - a significant 60 kilos less than before.

The power unit is mated to an eight-speed tiptronic transmission with optimised shift times. Audi's quattro permanent all-wheel drive system comes as standard.

An updated five-link suspension is used on the front axle while, at the rear, a five-link system replaces the trapezoidal-link suspension used on the previous model. Although the latest RS 5 Coupé sits much lower than the standard production Coupe, Audi says that comfort is significantly improved.

Buyers can opt for RS sport suspension with Dynamic Ride Control (DRC), ceramic brakes and dynamic steering with RS-specific tuning for an even more exhilarating drive.

The up-scale interior is bathed in black and comes lavishly appointed with leather sport seats and a flat-bottomed RS multifunction sport steering wheel.

A comprehensive range of infotainment choices is on offer along with other high-end technologies including a head-up display and as many as 30 driver assistance systems to enhance safety, comfort and efficiency.

According to the company: "The intelligent interplay between these systems represents another step on the road to piloted driving."
