At this year's annual Wörthersee Tour tuning event in Austria, Audi will unveil the A3 Clubsport Quattro concept, based on the S3 sedan and powered by a 2.5-liter turbocharged inline-five over the usual 2.0-liter turbo four. The result is 525 horsepower and 442 pound-feet of torque, good enough for a 0 to 62 mph sprint time of just 3.6 seconds and a top speed of 190 mph. Those figures are achieved in part by a larger turbocharger as well as an upgraded intercooler, with the power boost going through Audi's quattro all-wheel drive system and a seven-speed S tronic gearbox equipped with launch control. Additionally, there's a re-tuned suspension and carbon-ceramic brakes within 21-inch wheels. Check out detailed looks below.
