There aren't many people who would consider the current 394bhp Audi RS3 to be lacking in the power department.
ABT Sportsline certainly thought so, because they've just introduced a 'ABT Power S' upgrade that boosts the 2.5-litre turbocharged five-output cylinder's to 454 horsepower and 398 pound-feet of torque.
ABT claims that the software patch reduces the 0-62mph time from 3.8 to 3.6 seconds, yet despite being on winter tyres, we were able to match that time with a stock RS3.
Consider how fast the ABT will be in the real world.
Oh, and the German tuner will also enhance the RS3's electronically regulated top speed if you get your chequebook out.
Over 300kph (186mph) is reportedly attainable.
