The hottest version yet of the current Vauxhall Insignia, the 252bhp GSi, has been launched at the Frankfurt motor show.
The car is powered by a 2.0-liter four-cylinder turbo petrol engine that generates 295lb ft and is mated to a new eight-speed automatic transmission gearbox with paddle shifters.
Vauxhall says that the car can lap the NÃ¼rburgring Nordschleife faster than the previous-generation Flagship of the range topping VXR model, in spite of giving 69bhp.
It is said that the reason for the fast pace is the car’s improved agility, helped by the new Flagship of 160 kg lighter kerbweight and new four-wheel-drive system that offers a pair of vectors in the back.
The transmission line is used a GKN Twinster dual-clutch differential (such as the Ford Focus RS and the Range Rover Evoque) to power the rear wheels, the split torque independently to improve traction. In the front, the power is distributed via a more conventional electronic differential lock, which mimics a mechanical diff by braking the wheels experiencing slippage.
The Coach shows the system in a GKN test mule is based on the previous-generation Insignia VXR last year.
The GSi also uses adaptive dampers that come as a part of its mechatronics system chassis Flexride. The technology that continuously adapts damping rates, and also allows adjustments for steering and throttle and gearbox responses.
Four driving modes are included: Standard, Tour and Sport, as well as a Competition mode, which reduces the interference of the car’s electronic stability control. Double tap the button to turn off completely.
The GSi gets four-pot Brembo brakes and 18-inch wheels (20s are optional). It also has the tailored, leather-trimmed sports seats, a leather-wrapped steering wheel and metal pedals.
After the GSi of the launch, Vauxhall will add a diesel variant, although it is yet to reveal more details for the car.
