Ford Motor Company set veils off of their 2016 Shelby GT350 recently. The car, powered by Ford’s 5.2L flat-plane crankshaft V8 engine, is the most powerful engine ever built by Ford. The car has two variants with this engine, Ford Shelby GT350 Mustang and Shelby GT350R Mustang.

The muscle’s engine is wild, making 526 horsepower at 7,500 rpm, 429 pounds-feet of torque at 4,750 rpm and also this is the highest revving engine, redlining at a whopping 8,250 rpm. Transferring all this power to the wheels is the Ford’s six-speed manual transmission. The engine lacks the Ford’s Ecoboost technology though.

“The high-revving, naturally aspirated 5.2-liter flat-plane V-8 delivers on every target we set — high horsepower, broad torque curve, aggressive throttle response and lightweight,” said Jamal Hameedi, chief engineer, Ford Performance. He continued “Every change we made to this car was driven by the functional requirements of a powerful, responsive powerplant.”

Not only this is the most powerful naturally aspired engine by Ford, but it’s also the most efficient, in terms of specific output. It makes 102 horsepower per liter of displacement without the need of supercharging or turbocharging. The cylinder exhaust pulse separation has also been improved with the use of flat-plane crankshaft engine, thus improving engine’s breathing and efficiency. It also has a slightly over square bore and stroke of 94×93 millimeters, which helps in the better air intake and complete combustion of the gas.

In the battle of Mighty Muscles, horsepower isn’t the only thing that matters, lighter the car will be, less horsepower it’ll need. Ford kept the thing very well in their minds, and kept the load off the car. It is also the lightest of all the Mustangs that Ford produced. Comparing it with its rival, the Chevrolet Camaro ZL1, which features a 580-horsepower supercharged 6.2-liter V-8 engine, which wins in terms of horsepower here. The big daddy in the game is Dodge Challenger Hellcat, featured in the latest Fast and the Furious movie, which churns out 707 horsepower from its gigantic V8.

The GT350 and GT350R Mustangs will go on sale in the coming fall, Ford said in a statement. They also announced limiting of the existing 2015 Mustangs to 100 and 37 cars of GT350s and GT350Rs respectively.
