Driver : Bob Wollek

The 911 GT1 EVO 98 was the car created by Porsche to compete in the GT1 category in 1998, at the Le Mans 24 Hours and in the FIA GT international championship. At the beginning, the GT1 were Grand Touring cars modified for competitions, but in the last years they got more and more similar to racing prototypes.

Porsche had already run in GT1 in earlier years, but the ‘98 car was a brand new model. This was the first car built by Porsche with a carbon composite monocoque chassis. It came equipped with front and rear double wishbone suspensions with pushrod, 18” wheels, carbon brake discs. Engine was a six-cylinder, flat, 3.2 litres twin turbo, 4 valves per cylinder, water-cooled, unit, with maximum torque of 630 Nm at 5000 rpm and maximum power of 550 hp at 7200 rpm. Six-speed gearbox type was sequential with triple disc carbon fibre clutch. Fuel tank capacity 100 litres.

The first complete new GT1 car got on the track for the shakedown in the late February, in Weissach, on the private Porsche test track, with expert Bob Wollek at the wheel.

In 1998, the FIA GT championship was dominated by Mercedes, but Porsche was able to win the Le Mans 24 Hours.
