I’m back building best-in-class Mustangs again and it feels great! The 2013-2014 GT-4 Series is the fourth generation of high-performance Kenny Brown Mustangs, whose DNA goes all the way back to the 1986-1987 Saleen-R race cars I engineered, built and directed to win four National Championships in endurance sports car racing.

The latest S-197 Mustang with the awesome 5.0L Coyote engine has given me an outstanding platform to work my magic. This past season we have spent time at a variety of tracks around the country and burning up the highways developing, testing and validating the different components and packages for my 2013-2014 GT-4 Series Mustangs.

The GT4 nomenclature comes from my racing roots, and the GT-4 class in international FIA sports car racing designates production-based cars modified for racing that retain the original OEM architecture. In the case of the GT4 Series Mustangs, we retain the OEM architecture, but in my typical fashion make significant upgrades and improvements to offer the best driving and performing cars you will ever experience.

Yes, a super-fast, supercharged GT4-Sa Mustang with an Automatic. Until now all supercharged Kenny Brown Mustangs have come only with manual transmissions. But the new 6-speed automatic transmission in the 2014 Mustangs has changed the equation, and Kenny’s thinking, providing you all the excitement with just two pedals.

The GT4-S automatic Mustang is designed primarily as a wicked fast street car, but it feels right at home on the track. With a healthy 610 supercharged horsepower and all the carefully selected equipment that makes it a dream to drive.

The automatic combined with traction control make it a brilliantly quick, yet amazingly civil car just driving around town. This is the kind of Mustang that you can seriously spank a Viper with at the toll booth grand prix - with a cup of coffee in your hand.

If you're feeling really sporty, click the traction control into Sport Mode, drop the shifter into Select, and unleash the beast. The SelectShift lets you select gears up and down manually with a touch of a button, and the traction control in Sport Mode gives you tire smoking capability, but you better be hanging on to the steering wheel and forget the coffee because this speed monster demands respect.
