The Vauxhall Astra GTC can be prearranged with a choice of four engines – one diesel and three petrols. With 165PS, the 2.0 CDTi is an upgraded account of the diesel that’s fitted to some models in the Insignia and Astra ranges. All engines have a diesel particulate filter, six-speed transmission and Start/Stop as standard, maximising economy and performance. Delivering 380Nm of torque (including overboost function) the 2.0 CDTi engine provides outstanding mid-range acceleration for the GTC, mutual with a 0-62mph time of 8.9 seconds and a top speed of 130mph.
That torque also allows the Vauxhall Astra GTC a relaxed cruising gait, meaning a mutual mpg of 57.6mpg and C02 emissions of just 129g/km. It also gives drivers a range potential in excess of 700 miles.
Start/Stop and a six-speed gearbox are also standard on both versions of the 1.4-litre Turbo petrol engine. With either 120PS or 140PS, the 1.4T achieves a combined 47.9mpg and 139g/km of C02 emissions, yet each still delivers crisp performance with utmost torque of 200Nm delivered between 1850-4200rpm.
The most powerful engine in the choice is the 1.6-litre Turbo, which produces 180PS and allows the GTC to hit a top speed of 132mph.
The Vauxhall Astra GTC series starts at £18,495 for the 120PS Sport 1.4 Turbo and extends to £22,430 for the 165PS SRi 2.0 CDTi.
