Entrepreneurs Mark and Charlie want to build a new business selling electric Porsche 911s and they've asked Moggy to develop the prototype. Tasked with improving every aspect of the car – from handling to top-end speed – this is a mission Porsche-loving-Moggy is happy to take on. If he succeeds then there will be more 911 commissions to come. But converting an air-cooled petrol car, and maintaining the front to back weight balance, pushes the team to their limits. A track day test duel with a high performance petrol 911 awaits….. if the team can complete the car to a tight deadline.
