These increases are mainly down to the addition of the supercharger, but a whole host of other engine upgrades feature, including an upgraded exhaust system and improved cooling and air intake systems.
The engine sends its power to the rear wheels through a six-speed manual transmission. A six-speed automatic is optional.
The new VXR8 GTS can sprint to 60mph in 4.2 seconds, and has a limited top speed of 155mph. That makes it significantly faster than the outgoing GTS, which managed the same sprint in 4.9 seconds.
Torque vectoring and Magnetic Ride Control (magnetically charged adaptive dampers) with three modes of stiffness — Touring, Sport and Track — feature.
Mounted behind the gearlever is a dial that allows the driver to control the various electronic systems via one of four settings: Touring, Sport, Performance and Track. The systems controlled by this include the ESC, launch control, traction control, exhaust sound, torque vectoring and electric power steering.
Vauxhall claims that these improvements “deliver greater body control, sharper handling, and a significantly more pliant ride quality” than the previous VXR8 GTS.
Forged aluminium six-piston calipers with two-piece discs provide the stopping power. The 20-inch alloy wheels are shod in 255/35 R20 Continental tyres up front, and 275/35 R20 tyres at the rear.
A host of safety and convenience tech is included as standard. Among the features is a Vauxhall first: a Forward Collision Alert system. This can brace the brakes when a collision is imminent and warn the driver audibly and visibly on the head-up display.
A facelift for the new VXR8 GTS includes a front end that’s designed to make the car look wider. The front grille is also new. A large diffuser with integrated quad exhausts is one of the standout features at the rear, alongside a spoiler.
Improvements to the interior include leather sports seats, a new centre console with integrated infotainment screen, a new instrument binnacle and new switchgear.
