If you attended an IMSA race this year, you might have seen a pair of Shelby GT350Rs racing in the Continental Tire SportsCar Challenge. You definitely heard them—I can personally attest that their 5.2-liter flat-crank V8s made some of the loudest noises on the grid. Now, you can expect to see a lot more GT350Rs on track: Ford just introduced this new Shelby GT350-based GT4 race car.
Based on , the Ford Mustang GT4 made its official debut today at the SEMA Show. This Mustang racer was developed with Canadian engineering firm Multimatic, which ran the GT350R-C in IMSA last year and manufactures the road and race versions of the Ford GT.
The ready-to-race (and not-street-legal) Mustang GT4 shares its 5.2-liter flat-crank V8 with the Shelby GT350, but here, it's paired to a paddle-shift six-speed racing transmission. Suspension changes come courtesy of Multimatic, and include modified dampers, lower control arms, and rear stabilizer bars. Ford also added an FIA-compliant roll cage, 18x11-inch wheels, slick tires, and revised aerodynamics to turn the GT350R into a legitimate race car.
Thanks to new out-of-the-box racers like the Porsche Cayman GT4 Clubsport, McLaren 570 GT4, and the upcoming BMW M4 GT4, this entry-level sports car class has one of the most exciting grids in racing. The Mustang GT4 will certainly be a great addition to this field—and definitely a noisy one.
