2013 Ford Shelby GT500 debuts with 200+ mph
The new 2013 Ford Shelby GT500 is one of those vehicles that everyone loves to read about, and a vehicle that anyone would love to get their hands on. In a new announcement yesterday on the 2013 Shelby GT500, Ford tells us that the car that is named after racing legend Carroll Shelby, will satisfy everyone from the road racer, weekend drag racer, and the everyday driver.
We’ve reported here that the 2013 Ford Shelby GT500 5.8-liter supercharged V8 engine will pump out 662 horsepower and 631 lb. ft. of torque. That makes the car the most powerful production V8 engine in North America. Ford tells us that the 662 horses will propel the coupe to track speeds of more than 200 mph. In order to accomplish the increases in horsepower and top speeds, Ford has looked at every part of the powertrain in order to make the V8 more powerful and also efficient.
Nearly every vehicle system has been upgraded
Everything has been updated on the coupe and convertible models starting with a larger and more efficient supercharger which forces more air into the 5.8-liter V8. The supercharger design spins faster, the inlet volume has been increased, and the boost has been cranked up from 9 to 14 psi. Ford uses a new Twin Vortices Series 2300 blower that creates 2.3 liters of displacement and is a unique design to the engine.
Other improvements include new cross-drilled block and heads, an all-forged engine rotating assembly, updated camshaft profiles, upgraded head gaskets, a new carbon fiber driveshaft and upgraded clutch, transmission and axle. And with all that extra heat generated from the new supercharger, Ford has to increase the cooling capacity with a new higher-efficiency intercooler to cool the air going in.
The driveshaft and clutch also had to be upgraded to handle all that extra torque. The GT500 now uses a new single-piece carbon fiber driveshaft that is lighter and stiffer than the old two piece steel design. The new dual-disc design clutch has increased torque and rpm capacity and has a greater resistance to burst under extreme track conditions.
The transmission wasn’t left untouched and gets upgraded gears, bearings and housing to also handle the increased torque. The final drive gear ratio has been changed to 3.31:1 and every gear besides fourth has been optimized to increase performance. The new engine also continues to be exempt from the gas-guzzler tax, delivering an estimated 15 mpg city, 24 mpg highway. Ford claims that it’s 5 mpg better than the 2012 Chevrolet Camaro ZL1.
