THE MEZGER ENGINE
All Porsche 911s have had flat-six overhead-camshaft engines. But within that format, there have been many different designs, none more revered than the so-called ‘Mezger’ engine found in the back of the GT3 RS and many other 911s. It’s named after its creator, renowned Porsche engineer Hans Mezger.
Mezger did many engines for Porsche, including the 1.5-litre flat-eight that took Porsche’s only Formula 1 win (the 1962 French Grand Prix), the 1200bhp 5.4-litre flat-12 in Porsche’s all-conquering 917/30 Can-am car and the Porsche TAG Turbo engine that won three F1 world championships for Mclaren between 1984 and 1986.
In fact, Mezger was involved in almost all iterations of the flat-six up until water cooling was introduced in 1998, but the point is that while all other 911s then adopted the new and what would turn out to be sometimes troublesome engine, all the 911 Turbos and all the Gt-series cars stuck with the Mezger design right up to the 991-series. Why? Because it was a known quantity, had won Le Mans in the Porsche 911 GT1-98 in 1998 and was almost unbreakable. The fact that it sounded simply incredible, too, was merely the icing on the cake.
Mezger 3.8 in the back of this GT3 RS puts out 444bhp and revs to 8500rpm
