This is it, folks: the Ford Shelby GT350R Mustang is officially here. Hide your kids, hide your wife, and put the Chevrolet Camaro Z/28 on notice because Ford's biggest, baddest track-ready, street legal Mustang is here. Revealed today in Ford's own turf in Detroit at the North American International Auto Show, this latest generation of one of the most iconic muscle cars is every bit what we thought it would be when it was first previewed back in November. Although we knew back in 2014 that the GT350R would produce over 500 horsepower and 400 lb-ft of torque via Ford's first-ever production 5.2 liter dual-overhead-cam V8, knowing it’s finally officially here makes it so much more exciting. All told, this is the most powerful naturally aspirated engine that Ford has ever produced--one that they've paired with a specially tuned suspension, new antiroll bars, a lower ride height, and a massive hood vent. The GT350R even lost more than 130 pounds since the Shelby GT350 Track Pack model, with features such as the air conditioning, stereo, rear seats, carpet, and emergency tire equipment removed. However, for customers looking to ride in comfort, all of these features and more are available in an optional package. Visually, the GT305R is also a jaw-dropper, arriving with all of the distinct muscle car edge mixed with nice touches: contrast stitching, racing stripes, carbon fiber, and a new aero kit. The only bad news comes in the fact that it will be a limited production run, available only in the US and Canada later this year.
