As the most powerful street-legal Ford ever built, the all-new Mustang Shelby GT500 harnesses world-class muscle and powertrain technologies to attain supercar levels of performance. Its first-in-class 7-speed dual-clutch transmission, race-bred control strategies and advanced drive modes deliver a car that performs unlike any other domestic sports coupe.
Its 760-horsepower 5.2-liter V8 engine is the most power- and torque-dense supercharged V8 in the world. With 625 ft.-lb. of torque funneled through a Tremec® TR-9070 DCT 7-speed dual-clutch transmission, the Shelby GT500 achieves a 0-100-0 in 10.6 seconds.
“The range of brute-force drag acceleration, seamless road shifts and amazingly smooth shifts on the track further highlights how the soul of the Shelby GT500 is elevated in our most advanced Mustang ever,” said Ed Krenz, Ford Performance chief program engineer. “Effortlessly handling the 760 horsepower is our segment-first Tremec dual-clutch transmission, with an advanced control system that enhances GT500’s five drive modes to deliver a driving experience once reserved only for exotic supercars.”
Applying 625 ft.-lb. of torque to the pavement effectively requires a transmission and driveline that can do more than just handle a massive amount of power. Ford Performance engineers collaborated with Tremec to design a gearbox that offers maximum driver control with stunningly fast shifting and greater performance across a wide spectrum of driving environments. The team’s “and” solution is the Tremec TR-9070 DCT 7-speed dual-clutch transmission.
“In many ways, this is like having two transmissions in one,” said Pat Morgan, Ford Performance powertrain manager. “On one hand, it enables performance at the outer reaches of straight-line quickness with minimal torque interruption, yet provides an incredible amount of finesse and control in track environments for maximum stability and predictability at the limits of lateral acceleration.
To firmly and smoothly deliver torque, the TR-9070 DCT dual-clutch transmission has a novel wet clutch system with five friction plates in the odd-gear pack for a total of 155 square inches of surface area. In the even-gear pack, six friction plates provide 136 square inches of surface area. Transmission fluid is applied to the clutch surfaces only during thermal events for optimal cooling and minimal parasitic loss. Seven non-sequential helical forward gears with advanced triple cone synchros are carefully matched to the engine’s torque curve and are pre-selected by an electrohydraulic shift mechanism using energy-efficient low-leak solenoids that can execute shifts as quick as 80 milliseconds in sport mode.
“Contrary to popular belief, fast shifts do not always equate to better road performance,” said Morgan. “In every driving situation, we emulated what professional drivers do, whether it’s a smooth, precise heel-and-toe shift of a professional track driver or a much more forceful powershift like drag racers. We’ve designed the perfect shift every time.”
The 2020 Shelby GT500 has five drive modes that further enhance the driver experience with a flick of the console mounted mode switch. It instantly changes the car’s personality from a moderated “normal” car to a “track” master with more aggressive throttle responsiveness and gear selections. The system changes nearly every aspect of the car’s behavior, including ride dampening, stability control, antilock brake modulation and steering feel – even the sound and instrument panel change.
- In normal mode: the system selects gears and shift timing for moderated, everyday driving and seamless shifting.
- In sport mode: shift character changes, slicing shift timing by roughly 20 percent while throttle tip-in is more responsive and rpm ranges extend longer into the maximum torque curve.
- In track or drag mode: further changes the shift characteristics to pure performance. Take the Shelby GT500 into a turn, however, and the transmission immediately adapts with smooth, quick and seamless shifts to ensure maximum lateral g cornering by minimizing driveline disturbances.
“Every aspect of the Shelby GT500 driving experience changes with the mode – be that the throttle responsiveness and snap of the shifts you feel in the seat of your pants, or the ‘pop and burble’ of the exhaust in performance modes. It’s a full multisensory visceral experience,” said Morgan.
As the greatest-ever Mustang performance lineup hits the streets, the 2020 Mustang Shelby GT350R picks up new performance tech and colors from its stablemates to make it more fun to drive on the track and off. Enhancing handling and steering responsiveness, Shelby GT350R refinements for 2020 include redesigned front suspension geometry with a redesigned high-trail steering knuckle leveraged from the all-new Shelby GT500. To elevate driver confidence and steering precision, a new steering rack and recalibrated electric power steering control is also added.
“It’s always been our plan to take the latest innovations from the GT500 program and strategically apply them across the Mustang lineup,” said Ed Krenz, Ford Performance chief program engineer. “These latest updates to the GT350R keep its performance competitive and on the top if its game, whether that’s on the track or on the street.”
GT350R continues to also deliver against aggressive targets for weight reduction with a rear seat delete and carbon fiber wheels. Exhaust resonators also have been removed for weight savings with the benefit of creating a sharper exhaust tone.
For customers seeking more comfort in their Shelby GT350R, Ford offers an available Technology Package with a 12-speaker B&O premium sound system, Blind Spot Information System with Cross-Traffic Alert, Cobra Puddle Lamps and voice-activated navigation.
Standing apart from GT350, GT350R features distinct design details. Exterior touches include red painted brake calipers, red pin striping at the edges of the optional over-the-top racing stripes and Shelby GT350R badging. Inside is high-contrast red stitching, Shelby GT350R badging and the D-shaped steering wheel fitted with a red center mark at the top.
