MR Car Design decided that the already sporty Opel Insignia OPC could use a few enhancements in order to look even sleeker and become more potent in terms of total power and maximum torque.
That is why they fitted the car with a G-Ride air suspension and a set of Oxigin aluminium rims (8,5×20 at the front and 9,5×20 at the rear) which are wrapped in absolute adequate performance tires.
They have also optimised the software on the standard 325 HP and 435 Nm of torque engine, and fitted a new exhaust system that includes a race catalyst and a K&N air filter. As a result the MR Car Design Opel Insignia OPC has gained a total of 375 HP and 495 Nm of torque, which means it is now even better suite to face its rivals, the Audi S4 and the BMW 335i.
