The tuners at Hartge have released a new aftermarket package for the BMW 6-Series GranCoupe 640i and 640d models. They have taken the 3.0-liter inline six cylinder engine found in the 640i and increased the power to 367 HP and 520 Nm of torque. The 640d 3.0-liter diesel powerplant now produces 362 horsepower to go along with the 730 newton meters or torque. All this extra power comes from the boost of airflow through the stainless steel exhaust system and ECU tuning.

Besides the performance modifications, the BMW 6-Series models can also receive new sport springs to lower the ride height between 20 mm and 30 mm. Some styling customization’s to the exterior consist of the emblems on the hood and rear trunk, while moving inside the car you will notice bespoke floor mats, new aluminum emblems and pedals. Hartge kept it classy with this BMW 6-Series GranCoupe tuning kit.
