Since it is based on the platform for the Opel/Vauxhall Astra, the GTC Paris concept gives a strong hint of how the production three-door Astra could look. With the Astra Sports Tourer making its Paris debut too, the three-door plugs one of the few remaining gaps in the model range for General Motors’ popular C-segment model in Europe.
The GTC Paris is the work of the Opel/Vauxhall design team based in Russelsheim, Germany, under Vice President Mark Adams.
“As we move our brand forward, for us it was really important to really make an ultimate statement around this very expressive, very sculptural form,” Exterior Design Director for Opel/Vauxhall Malcolm Ward told AEI.
“There’s a lot of sculpture in the body, very strong shoulders at the rear and two or three really nice lines—the blade feature in the door, it goes from the A-pillar back down again; it does the exact opposite of the Astra, but you can see a similar execution on the Meriva or the Insignia. So you can see a lot of our brand DNA, but a lot more extreme," said Ward. "When you look over the rear, there’s this really nice feature line that grows out of the door handle instead of shooting all over the car that just makes the whole car, through the door, a lot rounder and softer, and that gives it a very different character.”
The GTC Paris measures 4460 mm (175.6-in) long and was designed to seat five. Although it shares many Astra parts, Opel/Vauxhall claims the chassis was designed for the car. It carries a revised version of Opel/Vauxhall’s Flexride adaptive damping system, used with the compound crank/Watts linkage rear suspension from the Astra.
The car is powered by a 290-hp (216-kW), 2.0-L turbocharged gasoline engine with a twin-scroll turbocharger and direct fuel injection. Cam-phasing variable valve timing is used for both cams. Twin balancer shafts and automatic engine stop/start are also featured. Power is fed through a six-speed gearbox to the front wheels and is regulated by a traction control system.
