It has been many an automotive enthusiast’s dream to tear down a windy back road in a track-only racecar. Very few will ever have the money or resources to road-prep an open wheel racer, but for the rest of us, there is this on-board footage of a Formula-style racecar blasting down a mountain road.
It's an age-old question: What's better, a tuned car or a car that comes from the factory with a ton of power? That debate will never be settled, but the professional hoons at Autocar added fuel to the fire by lining up two very unlikely opponents.
In one corner, we have the McLaren 12C (remember, they dropped the MP4) sporting a twin-turbo 3.8-liter V8 with 616 horsepower.
In the other corner, you have the Fensport Toyota GT86 Turbo with 335 horsepower. Autocar's Steve Sutcliffe tests both the street legal and more powerful racing-only "R" version, and then has the latter square off against the McLaren.
The McLaren is quicker in a straight line, but the Toyota ends up much faster in the corners. I won't spoil the ending for you, but it's a fun matchup.
If you still think that aerodynamics don’t matter, check out the extreme, where Cd is optimized at the expense of downforce, causing this Mercedes at Le Mans, and this Porsche at Road Atlanta, to become airborn!
