A completely new tuning kit for the BMW 5-Series GT has been released by the guys at Hamann. Carrying both technical and visual modifications, the most notable changes were made under the hood to the 530 diesel engine. Raising the numbers from 245 hp and 540 Nm of torque, the sport SUV now carries 275 hp and 620 Nm of torque. Hamann was able to accomplish this by tuning the Motronic engine management system to deliver more fuel and air. Now the exterior styling is what really enhanced the look of the BMW 5-Series GT.
