Powering the GTC is a modified version of the current Vectra OPC’s 2.8L V6 turbo sending up to 300hp through all four wheels via a six-speed manual transmission. The claimed 0-100km/h figure is a brief 6 seconds, while top speed is electronically limited to 250km/h.
The interior features electronic gizmos such as park-assist, a hard-disc for navigation and audio, and finally, an automatic parking brake that activates depending on vehicle speed.
