Audi RS3 is rumored to be unveiled at this year's Frankfurt auto Show. The source of the rumor says someone from inside Audi says the new RS3 will debut at the German show. Apparently, the new Audi RS3 will be powered by the same engine as the new TT-RS which has a 2.5 liter turbocharged engine. If this is true, the Audi RS3 will develop around 340 hp and 450 Nm of torque. coupled with the company quattro all wheel drive system, the Audi RS3 is set to do some serious damage.
Other sources say the Audi RS3 could come with a 350 hp or a 400 hp engine, but this puts it dangerously close to the R8 in terms of performance. So, a 400 hp version Audi RS3 is highly unlikely.
