The Porsche 911, produced since 1963, has been known for being a high performance two-door, 2+2 sports car. With a rear mounted six cylinder, Porsche has been very consistent from the first 911 models all the way through the current models. At the very top end of the 911 spectrum lie the GT3 and GT3 RS. This 2015 911 (991) GT3 houses a 3.8L flat-six pushing out 475hp at 8,250rpm. Shifts are deadly quick like the M4 DCT with the use of the Porsche Doppelkupplung (PDK) double clutch gearbox. Don’t mess with these track ready cars. Fitted with a roll cage, quick acceleration, and rear steering, expect to put up a tough fight.
