The Ford Mustang Shelby GT350 and GT350R will push out 526 hp and 429 lb-ft of torque.
The American automaker’s latest sports car is powered by a 5.2-liter V8 engine equipped with a flat-plane crankshaft and both models will have the same engine output, although the GT350R will boast a better power-to-weight ratio since it’ll tip the scales 130 lbs less than the standard GT350. With 526 hp, that means the Shelby GT350 and GT350R will push 102 hp-per-liter, making it the most power-dense and most powerful naturally aspirated road-going engine ever in Ford’s history. In addition, the 5.2-liter flat-plane V8 is also the highest-revving production V8 in the American automaker’s history with a redline of 8,250 RPM.
Peak torque will come in at 4,750 RPM while peak horsepower is at 7,500 RPM. According to Ford, the engine produces 90 percent of its peak torque from approximately 3,450 RPM through 7,000 RPM, giving it a racetrack-friendly spread of nearly 3,000 RPM between its torque and horsepower peaks.
“The Shelby GT350 program began with a clear objective – create the most balanced, nimble and exhilarating production Mustang yet,” said Jamal Hameedi, Ford Performance chief engineer. “Every change we made to this car was driven by the functional requirements of a powerful, responsive powerplant. The high-revving, naturally aspirated 5.2-litre flat-plane V8 delivers on every target we set – high horsepower, broad torque curve, aggressive throttle response and light weight.”
