Audi is sending the third generation of the S3 onto the streets with a newly developed engine that generates 221 kilowatts of power. The two-door compact can zoom from 0 to 100 kilometers an hour in just 4.8 seconds. With fuel mileage of 6.9 liters per 100 kilometers for the automatic and 7 liters for the manual transmission, the new engine is much more fuel-efficient than its predecessor.
