The Ferrari is a stock car but it is not average 458. This is the Speciale model which as we saw in a race against a tuned 997.2 Turbo and a standard 458 Italia it is pretty damn fast. The speciale gets a power boost to 597 horsepower and about 90 pounds shaved off of it for a curb weight in the 32XX pound range. Combine that with a dual clutch transmission and power sent to the rear wheels and it makes for a very quick car from a roll.
Even though the Golf has the power and torque advantage the Ferrari has the weight, shift speed, and aerodynamic advantages. This makes for a great race that is basically door to door with a slight edge to the Ferrari up top.
