Porsche 917 AKA The Car That Killed Can-Am Racing

In the hearts and minds of many, the Porsche 917 represented the pinnacle of Porsche's motorsports history and it is considered to be one of the most extreme road race cars ever created, even after almost four decades of being in retirement.

Despite its poor performance during its initial developmental period, the 917 soon reigned victorious after its debut on the racing circuits, earning 1st overall wins at both of the 24 Hours of Le Mans in 1970 and 1971. Later in 1972-73, the revised 917s dominated the Can-Am series in a similar fashion and became widely known as "The Car That Killed Can-Am-Racing".

In its most aggressive trim, with the aid of its twin-turbochargers force feeding air into twelve horizontally opposed cylinders at the stratospheric boost pressure of 39 psi, the 917 can produce upwards of 1,500 horsepower. With this amount of power, the 917 can accelerate to 60 miles per hour at 1.9 seconds from a standstill and has a top speed of 257 mph. Such numbers still commands nothing but awe and utmost respect to this very day.

However, as we all know, power isn't everything. Alot of drivers have had difficulty harnessing its power and have described the driving experience as fightentning due to primitive aerodynamics.
