The Insignia GSi is the fastest and most expensive version of Vauxhall saloon, but that doesn’t mean it can’t be improved.

Looks-wise, the Insignia GSi gains an updated front end consisting of a new radiator grille with stainless steel or carbon fiber trim as well as a number of new carbon elements.

Seen from the side, the Insignia GSi reveals new 20-inch alloys available in two designs: Heli Star and Evo Star. To improve road-holding, the vehicle now sits 30mm closer to the ground.

There are no photos of the interior yet, but the irmscher says the sport package brings stainless steel door sills with Irmscher lettering as well as high-quality leather seats.

As for performance upgrades, Irmscher says they are already developing a pack for the 2.0-liter turbocharged engine. The company will boost the maximum output to around 280 horsepower, up from 256. A small bump, but welcome nonetheless.

The tuning house’s upgrades for the Insignia GSi can be purchased individually or as a complete package.
