The new Astra GTC is very much inspired by the Opel GTC Paris Concept revealed last fall at the Mondial de l’Automobile. The compact and sporty five-seater with coupé appeal and dramatic proportions Astra GTC has a unique design which does not share any exterior element with other members of the Astra family, except for the outside rear view mirror housing and the rod antenna.
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.
The Astra GTC can be ordered immediately with a choice of four powertrains – one diesel and three gasoline units. More powertrains will be offered around the world premiere at the Frankfurt Motor Show. The sportiest versions including the future high-performance OPC will follow in 2012.
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 delivers up to 380 Nm of torque thanks to an overboost function and allows the 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 Astra GTC 2.0 CDTI can cover over 1,100 km.
Start/Stop is also standard with the two 1.4 turbo-compressed gasoline engines with 88 kW/120 hp and 103 kW/140 hp outputs. Both have a six-speed manual gearbox, deliver 200 Nm of torque and require 5.9 liters of fuel per 100 km (139 g/km CO2). The gasoline offer is currently topped by the 132 kW/180 hp 1.6 turbo with six-speed manual transmission, which has a top speed of 220 km/h.
The Astra GTC will have its world premiere at the 64th International Motor Show in Frankfurt am Main, September 15 – 25, 2011. Can be ordered as of June 7, 2011, Astra GTC 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).
