BMW F13 650i xDrive With Hartge Engine Upgrade Test Drive

Normally, Hartge is not only talking the talk but is also walking the walk. One of their latest upgrade kits is for the pre-July 2012 6 Series models, the 650i to be more precise.

The first model had the 4.4-liter N63 V8 engine under its bonnet and 'only' 407 HP and 600 Nm (442 lb-ft) of torque. The guys from Hartge upgraded this engine and took it up to 481 HP and 690 Nm (509 lb-ft) of torque.

With those new numbers, the 6er is completely transformed. In order to prove just how much faster the Hartge version is, they published a clip (as they always do) to showcase the more powerful Coupe.

The Hartge one accelerates from 80 to 200 km/h (50-124 mph) in 11.12 seconds, 3.47 seconds faster. That's around 44 meters further away than the standard version in a drag race.

However, meanwhile, in July 2012, BMW upgraded the 650i model and now it has 450 HP and 650 Nm (479 lb-ft) of torque. Those new numbers make it a lot quicker than the first version. Either way, Hartge did a great job, as usual.
