2009 BMW 335i vs 2010 Audi S4 - Automobile Magazine

Nearly a year after its debut in Europe, the new Audi S4 has finally come to North America, and more so than ever, this new S4 should be cause for trepidation at BMW. The all-wheel-drive system now sends a majority of the thrust to the rear wheels and also can actively apportion torque across the rear axle. That pricing move, in particular, has allowed Audi to realign the members of the A4/S4 lineup as they face off against the genre-defining BMW 3-series. The rather milquetoast A4 V-6 is gone, so while the A4 2. 0T pairs off against the 328i, the S4 now matches up against the turbocharged 335i. The old eight-cylinder S4 and RS4 previously bracketed the BMW M3, but for now Audi is leaving that... But the V-8 always did feel like overkill here, and we're certainly happy with the 37-pound weight loss and the dramatic increase in fuel economy, which goes from 13 mpg in the city and 20 on the highway to 18/27 (18/28 with S tronic), which also... Both cars are bristling with everyday, usable power, and our testing had the Audi and the BMW neck-and-neck from 0 to 60 mph (5. 2 and 5. 1 seconds, respectively) and even on to 100 mph (at 12. 6 and 12. 7 seconds).
