New Opel Insignia SuperSport chassis now in more variants

  • Forward wheel drive Insignias get ride and handling enhancing SuperSport chassis
  • Two more Insignia powertrains available with chassis package
  • HiPerStruts, Brembo brakes and OPC level tuning are included

    Opel is for the first time making its high performance SuperSport chassis available in its forward wheel drive mid-size Insignia cars. Two gasoline and diesel powered Insignias with forward wheel drive (FWD) will now benefit from a chassis package that consists of HiPerStruts (High Performance Struts), Brembo brakes and is tuned in line with OPC (Opel Performance Center) settings. This chassis combination was previously only available in the sporty Insignia OPC model and every other all wheel drive Insignia variant, which are always equipped with traction and stability enhancing electronically controlled Limited Slip Differentials (e-LSD) to distribute torque as required. Now the chassis can also be ordered in combination with the FWD variants of the 2.0 CDTI 118 kW/160 hp diesel and the 2.0 l turbocharged gasoline engine with 162 kW/220 hp. Together with the FlexRide system which offers three modes (Standard, Tour and Sport), adapting the car’s damping, as well as its steering and throttle parameters at the push of a button, the SuperSport chassis option costs 2,930 euro (rrp. Germany including VAT).

    The SuperSport chassis package benefits from HiPerStruts (High Performance Struts) on the front suspension, which are combined with highly effective Brembo brakes. These brakes consist of large, 355 x 32 mm, cross drilled discs, four piston, high strength aluminum calipers and high performance brake pads. Specially developed Co-Cast floating discs consist of a cast iron brake rotor and an aluminum disc bell.

    The HiPerStrut suspension which was first used in the high performance Insignia OPC marks a significant evolution of the regular Insignia’s MacPherson strut front suspension. It improves grip in wet or dry conditions and allows more power to be applied during cornering.

    While the suspension uses the same fixing points as in other Insignias, the kingpin inclination angle has been reduced from 13 to 9 degrees, therefore shortening the spindle length by 23 millimetres to 44 millimetres. Each of these reductions allows drivers to better exploit the Insignia power potential. The reduced kingpin angle means less camber loss, which allows the front tires to retain more contact with the road during cornering, therefore delaying the onset of understeer. The shorter spindle length significantly reduces torque steer reactions and improves resistance to steering kickback through rutted bends.
