It is unlockable as a Hard-to-Find car:


The 1970 Porsche #3 917 LH is the third variation of the Porsche 917 to appear in the Forza series, following the 1971 Porsche #23 917/20 and 1973 Porsche 917/30 Can-Am Spyder.

This model is chassis number 917-043, which was raced by Martini International Racing at the 1970 24 Hours of Le Mans, where it has finished in second position after a 917 KH short-tail model. The car is currently on display at the Simeone Foundation Museum in Philadelphia, USA.

The Langheck (abbreviated as LH and German for long-tail) was designed as the low-drag model of the 917. Using a 4.9 liter flat-twelve engine mated to a five-speed manual transmission, the 1970 LH has reached almost 240 mph (386 km/h) during qualifying on the old Le Mans circuit,[1] although it can only hit 221 mph (356 km/h) as top speed on Forza Horizon 4.
