10 examples of technology going from the racetrack to the road

MONTEREY, CALIF.—Few car brands have managed to stake out the kind of mindshare occupied by Porsche. Celebrating its 75th anniversary this year, the company just held its seventh Rennsport Reunion, a car show crossed with a race meet at the Laguna Seca racetrack in Northern California. It drew a crowd of more than 90,000 Porschephiles at the end of September.

From its start in the aftermath of World War II, Porsche has concentrated on using clever engineering to make cars for people who like to drive. Much of that clever engineering was first proven at the racetrack before making the jump to something a bit more road-legal. And almost all of it was on display at Rennsport Reunion, from early engines with twin spark plugs and early experiments with aerodynamics through turbocharging, hybrids, and now extremely high-performance EVs.

The early days

The first Porsche-designed racing cars predate the family firm and date back to 1934 and the fearsome Auto Union V16. But the first factory-built Porsche racing car took five years to follow the company's first road car, which appeared in 1948. When Porsche started building 356s, customers started racing them in sprints, hill climbs, and long-distance races, complete with pleas to the factory to see if it couldn't deliver a little more power, particularly from American owners.
