The 911 nameplate has been the mainstay of Porsche since its inception and the German automaker is riding a wave of enthusiasm after unleashing the most powerful 911 of all time: the new GT2 RS. Weissach decided to have some fun with its new supercar and unleashed it on ice with another special vehicle.
Porsche’s been killing it recently with its videos and the one below sees the 911 GT2 RS drift on a frozen lake alongside a classic 911 S/T rally car. The lake is at St. Moritz in Switzerland and it’s the perfect backdrop for the two high-performance machines.
The track-focused 911 uses a 3.8-liter twin-turbocharged flat-six that generates 690 horsepower and 553 pound-feet of torque. All of that power goes, in true Widowmaker fashion, to the rear wheels, which sounds like a recipe for disaster on the ice, but with a good set of winter tires it works out.
While most cars would be overshadowed by the GT2 RS, the classic 911 S/T rally car is a unique beast in its own right. In 1971, rules for the European GT racing series changed, allowing Porsche to increase the bore, but not the stroke, of its 2.2-liter engine.
The result was a 2,380 cc engine that had Biral cylinder liners, a bore of 87.5 mm, and a 66 mm stroke. The following year (1972), Porsche placed the 190-horsepower engine into the 911 S. With more experience on the track, the engineers fitted the engine with Nikasil liners and Mahle pistons, and increased bore to 86.7 mm. This gave the engine a larger capacity of 2,492 cc and a staggering (for the time) 270 hp.
Once again, the updated engine, which was labeled as a 2.5-liter, found its way into the 911 S. The racing-inspired S, when equipped with the M491 option and 2.5-liter engine became known as the 911 S/T, but its official designation was the 911 S 2.5.
The 911 S/T is a rare vehicle. Approximately 21 units of the car were made and two rally cars were produced as well. Seeing some of Porsche’s race-ready 911s pulling off some drifts at the same time is definitely worth four minutes of your time, don’t you think?
