Caranddriver sources say that Ford will drop a nuclear bomb in the horsepower war, as output for the most powerful Mustang would be as high as 620 horsepower. The boost comes from increasing the GT500’s current powerplant from 5.4-liters to 5.8-liters for the 2013 model year. This will be a swap of superchargers, with Ford ditching the current Eaton unit for the same TVS unit found under the hood of the ZL1.
The 2011 Ford Mustang Shelby GT500 is powered by an all-new aluminum-block 5.4-liter supercharged V-8 engine, which produces 550 horsepower and 510 ft.-lb. of torque, a 10 horsepower increase versus the 2010 model. The new mill is also some 102 lbs (46 kg) lighter than its predecessor, delivering a better power-to-weight ratio, improved fuel economy, acceleration, handling and steering precision.
The current GT500 deals with the sprint to 60 mph in 4.1 seconds and does the deals with the quarter-mile in 12.4.
Given that added power, the GT500’s 0-60 run could dip into the high 3-second range, with a 12-second quarter mile sprint. Flat out the GT500 should be traveling in excess of 190mph (306 km/h). That is one fast pony!
Some changes to the body will also be made, including the addition of LED running lights, and tail lights. Unfortunately, the live rear axle isn’t going away, so this sounds like a very wild car.
