BMW 3 Series: The recently redesigned "3er" sedan boasts an amazingly strong and efficient turbocharged inline-4 in 328i trim, and you can also get a formidable turbocharged inline-6 in the 335i. Cadillac ATS: Is there a new champion athlete in this segment? Cadillac thinks so with its Nurburgring-tuned ATS, and having driven it ourselves, we're tempted to agree. But as an all-around package, the A4 still gives the Caddy a run for its money. Mercedes-Benz C-Class: The C250 sedan's turbocharged 1.8-liter inline-4 actually makes the A4's engine feel powerful, but the Mercedes also offers muscular V6 power if you want more urge.
