New Audi RS5 Coupe Officially Revealed, Powered by a 450HP 4.2-liter V8

After the online leakage of the Audi RS5 Coupe brochure this past weekend, there was no point in holding back anymore, so the German automaker came out with an official release on its Geneva-bound BMW M3 fighter.

Developed by Audi's quattro GmbH division, the RS5 Coupe makes use of a revised version of the firm's 4.2-liter naturally aspirated V8 engine found in the previous RS4 and the current R8 Coupe.

In the RS5, the tweaked V8 engine delivers a maximum output of 450-horsepower at 8,250 rpm and 430Nm (317.15 lb-ft) of peak torque between 4,000 and 6,000 rpm. Power is transferred to all four wheels through a standard seven-speed dual-clutch S tronic transmission and a center differential in the quattro drivetrain.

With this configuration, the 4.2 FSI propels the coupe's 1,725 kg or 3,803 pounds from zero to 100km/h (62mph) in 4.6 seconds and on to an electronically governed top speed of 250 km/h or 155. Upon request, Audi can increase the top speed to 280 km/h or 174mph.

Not that it concerns your average RS5 driver, but Audi says that its hot coupe averages 10.8 liters of fuel per 100 kilometers or the US equivalent of 21.8 mpg.

It is worth mentioning that the RS5 comes equipped with a next generation quattro permanent all-wheel drive system that incorporates a self-locking crown-gear center differential which operates in conjunction with electronic torque vectoring.

Under normal conditions, the upgraded quattro system splits the power 40:60 front to rear but if necessary, up to 70 percent can flow to the front or as much as 85 percent toward the tail end.

The RS5 gets a revised suspension with the car sitting 20mm (0.79 inches) lower than a standard A5 and 19-inch alloy wheels with 265/35 tires or optionally, 20-inch rims and 275/30 rubber.

It also features a more powerful braking system with 365 millimeters (14.37 inches) ventilated discs at the front axle (380mm ceramic carbon-fiber brake discs up front are offered as an option) and an electronic stabilization program (ESP) that integrates a sport mode and can be switched off entirely.

To differentiate it from the S5 Coupe with its 354HP 4.2-liter V8, Audi gave the RS5 a special exterior treatment that includes a new single-frame grille with honeycomb inserts, a redesigned front bumper with oversized air inlets at each corner and silver splitter, plus flared fenders that hark back to the original quattro model.

At the back, there's a new rear bumper that houses a diffuser and two large oval-shaped exhaust pipes plus a hidden boot lid spoiler that automatically extends at a speed of 120 km/h (75 mph) and retracts at 80 km/h (50 mph).

Interior upgrades over the standard A5 Coupe's include a pair of sport seats, a sport steering wheel with perforated leather, red needles on the gauges and decorative inlays made of carbon fiber.

Optionally, buyers can trim the interior with decorative inlays in a dark, stainless-steel mesh look, while there's also a Carbon design package for the engine compartment and, for the vehicle body, there are styling packages in black or matt aluminum look.

The RS5 will go on sale in Europe this Spring with a base price of around €77,700.
