Another nice review of our latest favorite, the Audi S4.

However - and this is where Audi's engineers have demonstrated their genius once again - this downsizing has not only caught the zeitgeist by improving fuel economy and emissions, but it has also resulted in a car that will meet the challenge of the BMW 335i and Mercedes-Benz C350 head-on.

The S4 is also an attractive proposition for anyone who fancies a car with a bit of performance on tap, but doesn't want to attract too much attention - especially in the even more unassuming Avant form.
