If Porsche is proof that motorsport improves the breed, then its output of racing cars last year suggests a very healthy company indeed.

In 2016, Porsche delivered an astonishing 600 racing cars, which its boss of GT and motorsport, Frank Walliser, reckons makes Porsche the biggest builder of race cars in the world.

Dallara, for example, might argue the point, but for a company whose main business is road cars, 600 race cars is a massive number.

There’s also a direct link from the racing car department to road cars, Walliser said. For example, when the 919 World Endurance Championship team is wound down at the end of this year, its 200 engineers will be redeployed inside Porsche. “We’ll keep the people, yes,” he told Autocar at the Frankfurt motor show.
