This is a head-to-head battle we've been waiting to see: BMW's new M3 versus a Dinan-tuned 335i coupe. But we're only going to talk numbers and let the video tell the tale.

The BMW 335i has proven itself as a credible player in the sports coupe segment, particularly with a tweaked ECU to extract maximum output from its twin-turbo'd 3.0-liter inline-six. Dinan announced its Stage 3 package a few months back, which includes a fully-adjustable suspension and a handful of engine mods that bring output up to 406 hp and a kidney-punishing 460 lb.-ft. of torque (at 4,300 RPM). But it doesn't come cheap. All the necessary Dinan kit to get it up to Stage 3 spec (and get that nifty badge on the boot) costs around $14,000. But compared to the $71,000 $56,500 (no mark-up, no oxygen) base price of the new M3, it's still a steal. While the M3 has the peak horsepower advantage, you can't ignore the allure of the Dinan 335i's torque and lower curb weight. Will it be enough to match the M3? Hit the jump to find out.
