Five-Point Inspection: 2013 BMW M6

1. Annoying Engine Stop-Start Feature

It has power, style and surprisingly good fuel economy. If you haven’t guessed it, the subject of AutoGuide.com’s Five-Point Inspection is the 2013 BMW M6.

In case you didn’t already know, the BMW M6 has one hell of a powerful engine to play with. Its twin-turbo 4.4-liter V8 makes 560 hp and 500 lb-ft of torque, all while singing up to a 7,200 rpm redline.

That is, if it ever gets there. Maxing first gear out on anything other than a highway on-ramp is grounds for jail time.

On the slower side of daily driving, you’re going to deal with BMW’s engine start-stop technology. Yes, it saves fuel. But it also means that jumping from a foot on the brake to the gas yields disappointing results.

The system is pretty good at starting the engine quickly, but there’s still a little lag time. It’s fun for the first day when the engine roars after every stop sign. Then it gets old faster than the M6 hits 60 mph…. which, by the way, takes just 4.1 seconds.
