They are joined by the latest addition to the GTC range, the 195PS BiTurbo diesel model.

The revised styling by VP of Design Mark Adams gives the cars a more bold and aggressive appearance. Both body styles get a new front grille, with repositioned logo-bar in the upper section and a re-styled lower section too. New front indicator lamps and a new design of fog lamp (where fitted) complete the front-end revisions. The rear of both models has also been refreshed, with new rear-panel styling complemented by a chrome lower moulding.

The Astra GTC 2.0 CDTi BiTurbo, will become the most powerful non-VXR model in the range, producing 195PS and 400Nm of torque. And while the extra power and torque give it a healthy lift in performance with 0-60mph arriving in just 7.8 seconds and a top speed of 139mph, the BiTurbo still achieves a combined 53.3mpg and CO2 emissions of 139g/km. All BiTurbos receive Vauxhalls Start/Stop system as standard.

Uniquely in this class, the GTC uses a sequential turbocharging system, with the smaller turbo accelerating quickly at lower speeds to eliminate lag, providing 350Nm of torque from just 1500rpm. In the mid-range, both turbochargers work together providing maximum torque of 400Nm between 1750-2500rpm.
