Ford Mustang GT Convertible
Available for the 2010 Mustang are a 4.0-liter V-6 engine, which is rated at 210 horsepower and 240 pounds-feet of torque, and a 4.6-liter V-8 engine, which is rated at 315 horsepower and 325 pounds-feet of torque. Each is mated to five-speed manual or five-speed automatic transmissions. Horsepower gains on the V-8 are achieved by the cold-air induction system pioneered through Ford Racing Technology.
The intake is tucked behind the driver-side headlamp, mounted in an air box specific to the Mustang. Extensive sealing modifications ensure cold air from the front of the Mustang feed the engine. A true ram-air system offered on a base GT vehicle is a first for Mustang.
“That means more horsepower and more torque in all driving conditions,” Randle said. The redline for the V-8 is increased 250 rpm to 6,500, and revised calibration ensures the customer fully feels these changes. Both the V-6 and V-8 engines have larger exhaust tips, growing to 3 and 3 ½ inches, respectively, up ½ inch from the previous model. The V-8 exhaust features polished tips.
“The 2010 Mustang runs great on regular fuel, and that is where we quote our peak numbers, but we also have a great dual-adaptive knock calibration that allows the 2010 Mustang to run on regular fuel as well as premium fuel, and the system figures it out itself,” said powertrain supervisor Chris Roxin. “It also improves the torque of the engine in the low- to mid-rpm range.”
The powertrain feel also is enhanced by intake and exhaust sound tuning that delivers Mustang’s signature sound. “All the better to hear that famous Mustang roar that’s been inspiring customers for more than four decade,” Randle said.
