The 2013 Bentley Continental GT Speed is the updated GT range’s high-powered spawn and is officially the fastest ever vehicle from the company. The model is set to make its worldwide debut at the 2012 Goodwood Festival of Speed where the pre-production version of the model will be put through the paces in the infamous uphill climb by the driving trio of Derek Bell, Guy Smith and Juha Kankunnen. The first of the 2013 GT Speed cars will begin deliveries by October later this year.
