Last week, BMWBLOG headed over to Munich, Germany, to test drive and review the new BMW M4 Convertible. Our full review can be found here. While putting the M4 Convertible through its paces on curvy roads and on the Autobahn, we decided to see if we can reach its top electronically-limited speed.

The video below gives you a look at the tachometer showing the 270 km/h mark, about 10 km/h lower than the advertised top speed which usually tends to be slightly lower. To capture the exhaust sound, we used another GoPro camera placed right above the exhaust tips.

The 2015 BMW M4 Convertible is powered by a twin-turbo 3.0-liter inline-six which makes 425 hp and 406 lb-ft. That’s barely up from the last-gen M3′s peak 414 hp, but up significantly in the torque department.


We’ve also added some of our driving notes to accompany the footage, so click play below.
