2013 Ford Mustang Shelby GT500 features clever variable-RPM launch control

When you've got the most powerful factory V8 in the world, even the best driver can struggle with getting that power to the pavement. The 662 horsepower and 631 pound-feet of torque the 2013 Ford Mustang Shelby GT500 is packing can easily turn its rear tires into expensive clouds of smoke. That's why the 2013 Ford Shelby GT500 is the first Shelby Mustang to be factory-equipped with launch control. "With so much more power and torque on tap from the new 5.8-liter V8," says SVT senior engineer John Pfeiffer, "launch control makes it easier for drivers to take advantage of the performance." What's different about the Shelby GT500s launch control is that drivers can engage it by just pressing a single button, and it's also capable of being fine-tuned for the best reesults.

Launch control is by now a familiar technology, with systems operating by holding engine RPM at a set point to help facilitate clean, repeatable launches. "Launch control is essentially a special mode of the traction control system that integrates the brake and engine management systems to keep the tires balanced on the peak of the mu-slip curve," explains SVT's Pfeiffer. In plain English, it's designed to send as much torque to the tires as they can handle. What's different about the system in the 2013 GT500 is its flexibility. "Most of our competitors' launch control systems have a fixed engine launch speed," says SVT Engineering supervisor Eddie Khan, but since "not every driver has the same style, and surface, tire, and climate conditions vary," he points out, "we've given Shelby GT500 drivers the ability to adjust the engine speed to achieve the best and most consistent performance."

Drivers can use TrackApps through the instrument cluster or tap a switch to the left of the instrument panel to enable the system. Through TrackApps, the engine launch rpm can be adjusted between 3,000 to 4,500 rpm with steps of 100 rpm. There are other tricks up the GT500s sleeve, too. Extinguish the traction control while using launch control and you'll get an rpm-only mode that keeps the brakes out of the picture to avoid sacrificing any possible speed. Launch control also works with the different stability control modes to allow some wheelspin when that's the fastest way out of the hole. "It's not as intrusive as some TC systems have been in the past," said SVTs Khan. "We'e given our drivers the ability to exert control over all the power and torque this Mustang can produce."

Would love to test this thing out. Holeshot on a live axle in my 03 Cobra was a pain. It's nice that they finally understand the original TC systems were pointless.
