What is it
Vauxhall did pretty well out of the old three-door Astra. Its distinctive lines helped it take 20 per cent of all Astra sales and a full 40 per cent of that total were right-hand drive versions sold in the UK. No surprise, then, that Vauxhall is putting extra effort into the new Astra GTC to make sure that it builds on the British enthusiasm for the model.
Vauxhall says it’s aiming the GTC directly at the Renault Megane Coupe and the VW Scirocco. The entry-level 118bhp 1.4-litre turbocharged Sport model will cost £18,495, undercutting the base VW coupe by £1100. This model - the range-topping 178bhp petrol-engined version - comes in at £21,830, making it a direct rival in virtually every parameter for Renault’s Megane 180 GT Coupe.
The GTC shares nothing externally with its hatchback sister, save for the door handles. The wheelbase is also 10mm longer, it rides 15mm lower and the front and rear tracks have been widened by 40mm and 30mm, respectively. In the flesh, the GTC looks purposeful, particularly from behind, while being a much more polished piece of styling than its predecessor.
What’s it like?
Under the skin, the effort that’s gone into distinguishing the GTC in this market is impressive. At the rear is a modified version of GM’s clever compound crank axle and Watt’s link set-up. Vauxhall says it offers advantages over a multi-link set-up including straight-line stability, minimal lateral deflection in corners and greater compliance and ride comfort at the rear.
