The new Opel Astra GTC stands out with sharp design and driving capabilities. On the outside, sculpted shapes with precise accents add drama to clean, sweeping coupé lines. And on the road, all opel Astra GTC versions benefit from a premium front axle layout with HiPerStrut – High Performance Strut – that ideally combines with the clever Opel patented Watt’s link rear axle to provide unmatched stability and the sharpest driving precision.
The Opel Astra GTC mechatronic chassis features an exclusive, high-tech front suspension architecture, similar to the one of the Insignia OPC, that improves handling performance and provides the sharper steering demanding drivers expect in a sporty-looking car.
Compared to the five-door Astra, the ride height of the GTC is lowered by 15 mm while the basic dimensions of the chassis slightly increase. Due to extended control arms in the rear, the wheelbase grows by 10 mm, from 2,685 to 2,695 mm. Both tracks are wider, at 1,584 mm (+ 40 mm) in front and 1,588 mm (+ 30 mm) in the rear. This allows for the accommodation of sporty wheels with enhanced tire diameter, which improve both stability, road stance and visual impact.
All Opel Astra GTC versions are fitted with an extra feature, normally only available in high-end sports cars: front suspension with High Performance Strut (HiPerStrut). Compared to the standard McPherson suspension from the Astra, HiPerStrut has reduced kingpin inclination and offset and a shorter spindle length. This improves wheel guidance and grip, reduces torque steering reactions and increases cornering power, offering Astra GTC drivers the sporty, crisp feel they expect, with enhanced precision and feedback.
The Opel Astra GTC can be ordered immediately with a choice of four powertrains – one diesel and three gasoline units.
The upgraded 2.0 CDTI common-rail turbo diesel engine with output raised to 121 kW/165 hp is fitted with a diesel particulate filter and a six-speed manual transmission. Opel’s new Start/Stop technology which reduces fuel consumption in urban stop and go traffic is standard equipment. The 2.0 CDTI combines excellent performance with high efficiency. It delivers up to 380 Nm of torque thanks to an overboost function and allows the Opel Astra GTC to reach 100 km/h in 8.9 seconds. Top speed is 210 km/h. The combined fuel consumption does not exceed 4.9 liters of diesel per 100 km and CO2 emissions are 129 g/km. With its 56-liter fuel tank, the Opel Astra GTC 2.0 CDTI can cover over 1,100 km.
Four powertrains and two trim levels can be ordered as of June 7, 2011. Prices so far range from 21,750 euro (Astra GTC Enjoy 1.4 Turbo 88 kW/120 hp) to 27,855 euro (Astra GTC Sport 2.0 CDTI 121 kW/165 hp).
