I bought a later model Mustang to replace my '07 GT. The new car is a white 2013 that I added blue LeMans stripes to shortly after it came home. This car has the 5.0 liter DOHC V8 with 420 hp/390 ft-lbs instead of the 3 valve 300 hp/325 ft-lb SOHC engine in the '07. And a 6 speed automatic transmission. A first for me in one of my “toy” cars.
I miss the manual a bit but the 6 speed auto is pretty darn good. The car gets better mileage and its faster! Ahhh, technology. The final drive is shorter at 3.15:1 compared to the 3.55:1 in the '07 but first gear is so high, the multiplication from 1st to final drive is the same as the '07. The 6th gear overdrive is similar to the old 5 speed manual’s overdrive so the engine is turning lower RPM at highway speeds.
