The GTC will rival the likes of the Renault Megane Coupe and the Volkswagen Scirocco, with its three-door coupe layout, based on the five-door Astra. Every aspect of the GTC is said to have been re-engineered above the five-door model, except for the door handles.
The GTC will be available with four engines initially, including two versions of a 200Nm 1.4-litre turbocharged four-cylinder petrol engine (88kW/103kW), as well as a 1.6-litre turbocharged four-cylinder engine producing 132kW. A CDTI 2.0-litre turbodiesel version will offer 121kW and 380Nm.
Equipped with a six-speed manual transmission across the range, the GTC is being pitched as proper sports hatchback. It's 10mm lower than the standard five-door, 40mm wider at the front and 30mm wider at the rear. Combined with a newly developed HiPer strut front suspension and Watt’s link rear axle, Opel says it will provide "unmatched stability and handling precision".
Opel Design vice president, Mark Adams, said in a recent report,
"We wanted the Astra GTC to be the ultimate expression of Opel's design language ‘sculptural artistry meets German precision' and to embody our passion for the automobile."
The Opel GTC will be officially unveiled in the flesh at this year's Frankfurt Motor Show in September. It's anticipated to be a cracker of a car.
