BMW 6 Series Tuning

Hartge shifts BMW 6 Series Cabrio into a higher gear

Hartge has been offering the 2012 BMW 6 Series Cabrio an aerodynamic kit since about the middle of last year. For 2012 however they’ve decided to add more.

Not more kits or more bits to the original kit, just more power underneath its sinuous looking body.

Each of the powerplants currently available under the bonnet of the 6 Series convertible can get a new exhaust and an ECU remap from Hartge.

The exhaust system is basically the same though its adapted between to fit either the V8 or I6 exhaust manifolds. It consists of a stainless steel ensemble with new cats, silencers and mufflers.

With the ECU remap things are a little different. Starting off with the BMW 640d Cabrio, the 3.0 liter twin turbocharged inline six gets the first call.

Power goes up from 313 horsepower to 362. The torque figure also grows up to 538 lb-ft of torque with most of it available as low as 1800 rpm.

The 3.0 liter inline six in the 640i Cabrio gets tuned up from 320 horsepower to 384 horsepower and 398 lb-ft of torque.

With the top of the line 650i Hartge pumps the 4.4 liter turbocharged V8 by the biggest amount.

Starting with 407 horsepower it now produces 490 hp and 530 lb-ft of torque. This version is available with either rear wheel drive or the xDrive option as well.

The original body kit and wheel options are still available. What isn’t available however is the pricing for any of these changes.

If you’re interested your only option is to contact Hartge themselves who’ll give you the final details on costs and availability.
