Vauxhall explains unique Astra GTC

He said of the three-door coupe: “The GTC is recognisable as an Astra but every panel has been changed. The only common parts are the door handles and the roof aerial.”

The changes in the Vauxhall Astra GTC exterior are instantly noticeable and the car overall looks lower-slung than its Astra hatchback sibling.

Adams added: “If you look at a family, they don’t all look the same – they have similarities. And that’s what he is looking for at Vauxhall.”

The new Vauxhall Astra GTC is a three-door car capable of seating four. According to Adams, despite the coupe sloping roofline, he could easily fit in the back.

“I’m 6′ 4″,” he explained, “but I can still sit comfortably in the back.”

Designed as a competitor to the Volkswagen Scirocco, the GTC uses a choice of engines ranging from a 1.4-litre petrol in three power outputs to a range-topping 2.0-litre diesel option.

Prices for the new Vauxhall Astra GTC start from under £19,000, but the range-topping diesel adds another £4,500 to this price. However, this does put the Astra GTC below the Scirocco in terms of price.

Vauxhall hopes to sell 13,000 Vauxhall Astra GTCs in its first year once it goes on sale in November. This would boost Astra sales, which currently outstrip even the Ford Focus in the UK.
