Audi RS3 tuned to 510 HP by B&B

German tuner B&B is adding some serious horses to the 2012 Audi RS3.

The first stage already represents a big jump for the turbocharged 2.5-liter five-cylinder engine with a standard output of 340 PS (250 kW / 335 hp) and 450 Nm (332 lb ft) of torque. B&B takes that up to 410 PS (302 kW / 404 bhp) and 560 Nm (413 lb-ft).

A modest bump follows with stage 2 which takes power to 425 PS (313 kW / 419 bhp) and 580 Nm (428 lb-ft). Then it's onto 450 PS (331 kW / 444 bhp) and 600 Nm (442 lb-ft).

Finally, for €15.950, comes 510 PS (375 kW / 503 bhp) and 680 Nm (501 lb-ft) achieved mainly by means of a larger turbocharger and a high-performance stainless-steel exhaust.

At 510 PS, the Audi RS3 does the 0 to 100 km/h sprint in just 3.5 seconds and can hit a top speed of 310 km/h (193 mph).

B&B also offers a new two-mode sport suspension (Comfort and Sport), a lowering by 20 mm, 19- or 20-inch wheels, and a high-performance brake system.
