It's still more than a year until the next-gen BMW M3 will go on sale as a 2009 model. But AutoWeek's profiling the latest in M-Power. We're still buzzing from the sharp kack! of the M3 Concept's high-revving, 4.0-liter V8, as the prototype was rolled into the Geneva show's kleig lights. Now, AW consolidates the details of BMW's new V10 on the half-shell. It produces 420 hp and a relatively light 295 lb-ft of torque at 3900 rpm. Redline is 8400 rpm, which can be goosed by a six-speed manual. Is it all just overkill, or will the M3 be a fitting downline to BMW's touring-car racers? We'll know next year. – Mike Spinelli
