Porsche 917 K (Classic)
The Porsche 917 K is one of the most iconic endurance racers ever built, a fearsome German prototype made famous by its dominant run in the early 1970s. The "K" stands for Kurzheck, or short-tail, the aerodynamic configuration that made the 917 much more stable and usable at speed on fast circuits like Le Mans.

In the Simulator Feel
The 917 K is a wild, lightweight, high-speed classic prototype that demands respect from the first lap. With very little mass and a huge amount of power, it feels explosive in a straight line and beautifully alive through fast corners — but it can also be nervous and unforgiving at the limit. Compared to the earlier long-tail versions, the Kurzheck is a bit more settled, yet it still has that raw, mechanical race-car character that makes vintage Porsche prototypes so rewarding to drive.
Engine & Sound: The flat-12 delivers a deep, angry howl that hardens into a piercing wail as the revs rise. Throttle response is immediate, and the engine loves being worked hard, building speed with a dramatic surge that feels mechanical and unfiltered. The soundtrack is a huge part of the experience — one of the great sounds in motorsport history.
Handling Characteristics:
Cornering: Fast and confident once loaded up, but it can feel twitchy on entry and very sensitive to steering inputs.
Traction: Powerful but tricky; the rear tires can step out quickly if you apply throttle too early or too abruptly.
Braking: Strong for the era, though nowhere near modern prototype levels — braking points need commitment and anticipation.
Top Speed: Excellent on long straights, with the short-tail body helping it remain competitive at high speed.
Driving Style Tip: Drive it with patience and rhythm. Keep your inputs smooth, avoid sudden weight transfers, and let the car settle before feeding in power. It shines on fast, flowing tracks where momentum matters more than aggression.
Livery & Aesthetics: The 917 K is pure motorsport legend — low, wide, and unmistakably beautiful in its short-tail form. Martini, Gulf, and factory Porsche liveries all look fantastic on it, and the tiny cockpit and exposed bodywork give it an authentic, old-school prototype presence.
Whether you're chasing vintage glory or simply want to experience one of the most famous endurance racers of all time, the Porsche 917 K is a thrilling classic that still feels special every time it hits the track.
