Sir Richard Branson doesn’t pull his punches. In a press conference to announce his Virgin Racing team’s link-up with DS Automobiles in Formula E, he declared that the all-electric racing series would “overtake Formula 1” in terms of popularity and significance in five years.

“In the next two or three years Formula E is going to grow as quickly as clean energy is in general. I think things are going to move that rapidly now,” he added.

He didn’t stop there, making the prediction that petrol engines will be nigh-on obsolete in road cars in the year 2035.

“I’m willing to bet that in 20 years from now there will only be battery-driven new cars being built,” he said.

“What goes on inside a petrol-driven engine is really complicated, out of date and polluting. It will disappear over the next 20 years.

“Battery-driven cars are the things of the future and companies that move in that area are the ones that are going to dominate the market place.

I disagree with Branson on both counts, and although his comments have generated plenty of headlines, it must be remembered that he isn’t an expert on the intricacies of the sport.

F1, despite having some work to do to improve the show for the fans, will not become obsolete in five years; there’s far too much money sloshing about in the sport for that to happen, and the organisation behind it is extremely well-established.

And 20 years in road car terms is perhaps three model cycles, during which petrol-powered engines will continue to get ever-more frugal, especially when combined with hybrid systems.

Although Branson’s pronouncements didn’t quite convince me, there’s no doubt they were well-meaning and not without merit.

Formula E has done many things right in its first season, which draws to a close in Battersea Park, south London, tomorrow.

It has proven that battery-powered single-seaters can race wheel-to-wheel, and attracted a pretty strong field of drivers to pilot them.
