Le Mans Trials

Porsche won the 4-hour race at Le Mans last year with the 911 Carrera 3-litre, but this year the debut of the version was less conspicuous, both cars retiring with mechanical failures. An Eberspacher/KKK version was less conspicuous, cars retiring with turbocharger boosting at 1.5 atmospheres virtually doubles the output of the production-based, 2,140-c.c. six-cylinder engine to 450 horsepower, but both cars had their engines over-revved by the drivers, with dire results. They will take part in all the European endurance races this year.
