The Porsche 910 was entered in mid 1966, starting with the 1966 European Hill Climb Championship from Sierre to Crans-Montana in Switzerland.

At the 1000 km Nürburgring in 1967, a fleet of six factory cars were entered in an attempt to score the first overall win in Porsche's home event.

In Le Mans, the new Porsche 907 "long tails" were already entered, finishing 5th in front of a 910 and two 906.

In hillclimbing, the career of the short and light open-top 910/8 "Bergspyder" version with its 8-cylinder continued, winning the 1967 and 1968 European championships.

At the hillclimb of Ollon-Villars, which counted towards the World Sportscar Championship in 1967, the 910 even scored a 1-2, with Gerhard Mitter and Rolf Stommelen beating Herbert Müller and his big V12-Ferrari P.
