The carmaker's most potent production car has recently been released in the form of the Vauxhall VXR8 Bathurst S which comes with 552 hp generated by the merger of a Walkinshaw Performance 122 supercharger and the newest Corvette-derived 6.2-liter LS3 V8 engine. This excessive power is 20bhp over the previous generation VXR8 and 127bhp over the present normally ventilated car.
Torque is also enhanced by 127lb-ft making the total 527lb-ft. The Barthurst S receives more rigid height-adaptable springs and customized, individually adaptable coil-over dampers. Standard stopping power comes from six-pot brake calipers and four-pot calipers for both front and rear, respectively.
The feature that gets most interest in the VXR8 Barthurst S is what the carmaker calls the "Bi-modal exhaust" which also comes with the non-supercharged variant.
The system, which is 2.5 inches in diameter, allows two settings: 92 dbA for street driving and 102 dbA for optimum. The VXR8 Barthurst S is priced beginning at ₤44,995, while the exhaust with dual audio settings comes at ₤1,600.
