Vauxhall Astra GTC

The third body style to come off the new Astra’s Delta platform (following the Hatch and last year’s Sports Tourer), the only elements the GTC shares with its siblings are door handles and the roof aerial – even the wheelbase and tracks are different. Brit, Mark Adams, Vauxhall’s Vice President of Design, has aimed to create a car that looks like it’s been plucked from the class above, with its low, wide stance and simple, yet rakish lines.

The HiPerStrut uses the existing attachment points from the regular Astra, and has a reduced kingpin inclination and a shorter spindle length. This reduces levels of torque-steer, improves grip – and therefore cornering power – while also enhancing steering precision and feedback.

At the front of the car, a centreline crease is complemented by slim, ‘eagle-eye’-style headlamps featuring wing-shaped daytime running light graphics. A chrome emblem bar running across the dramatic trapezoidal grille – mounted lower than on other Astras – completes the picture from the front.

The GTC’s rear treatment is equally dramatic. Its powerful shoulder section gives the car imposing proportions and a purposeful road presence. The line from the C-pillar wraps around the tail and the rear spoiler, which integrates with the roofline. LEDs – optional across the GTC range – highlight the stretched ‘wing’ motif created by the tail lamps.

The Astra GTC can be ordered with a choice of four engines – one diesel and three petrols.

With 165PS, the 2.0 CDTi is an upgraded version 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 excellent mid-range acceleration for the GTC, combined with a 0-62mph time of 8.9 seconds and a top speed of 130mph.

That torque also allows the GTC a relaxed cruising gait, meaning a combined 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 maximum torque of 200Nm delivered between 1850-4200rpm.

The most powerful engine in the range is the 1.6-litre Turbo, which produces 180PS and allows the GTC to hit a top speed of 132mph.
