We’ve been waiting for a long time to hear what the exact specifications for the new Mustang would be. Well now the wait is over, and we can finally examine just what kind of power the 2015 Mustang is going to pack. Ford is offering three different engine options for the Mustang, including four, six and eight cylinder configurations.
The standard engine configuration will be a 3.7 liter V6, producing 300 horsepower and 280 ft. lbs. of torque. This is a slight decrease over the current 305 horsepower six cylinder Mustang. Those with more to spend and more passion for driving fast will be availed the option to upgrade to the Mustang EcoBoost, which features a 2.3 liter turbocharged, four cylinder EcoBoost engine. The four cylinder EcoBoost produces 310 horsepower and 320 ft. lbs. of torque. Marketed as the Mustang EcoBoost, it will also be the first Mustang to be turbocharged since the 1986 Mustang SVO. Featuring an ‘upgrade’ to a smaller engine may seem somewhat counter-intuitive, but it constitutes Ford’s effort to promote its new, efficient EcoBoost line of engines. The EcoBoost four cylinder has undergone various improvements over the conventional design in order to withstand the additional stresses of such high power generation, including:
- Forged-steel crankshaft
- Piston-cooling jets
- Steel piston ring carriers
- Premium bearing materials
- Upgraded valve seat materials
- Forged-steel connecting rods
- High-pressure die-cast aluminum cylinder block with ladder-frame bearing caps
- Deep-sump, die-cast aluminum oil pan
The 5.0 liter Coyote V8 will be available in the Mustang GT, with a power output of 435 horsepower and 400 ft. lbs. of torque. Various upgrades have also gone into the 5.0 liter V8, including:
- Larger intake valves
- Larger exhaust valves
- Revised intake camshafts
- Revised exhaust camshafts
- Stiffer valve springs ensure valves close completely at high rpm
- New cylinder head casting – revised ports provide straighter path to the valves for less restrictive intake and exhaust flow; combustion chamber modifications accommodate larger valves
- Sinter forged connecting rods are lighter and more durable for high-rpm operation
- Redesigned piston tops – deeper cutouts clear the new larger valves
- Rebalanced forged crankshaft to support higher-rpm operation
Other new upgrades are common across the entire model range, including independent rear suspension, upgraded brakes, and a slightly redesigned exterior that aims to hearken back to the ‘fastback’ era of the late 1960s. For the V6 and EcoBoost, the brakes available are two piston front setups with 320 mm rotors, adjoining a single piston rear setup on 320 mm rotors. The Mustang GT comes equipped with a four piston front setup on 352 mm rotors, accompanying a single piston setup on 330 mm rotors in the rear. An additional performance pack adds a Brembo six piston setup on 380 mm front rotors, with the rear remaining unchanged. Weight varies, depending upon engine choice, but the range is between 3,500 lbs. for the EcoBoost and 3,700 lbs. for the GT; the lightest configuration is the EcoBoost with an automatic transmission, weighing in at 3,524 lbs. All three engine options are available with a six-speed manual or six-speed automatic transmission.
The 2015 Mustang will have a base price of just over $24,000, and we do not yet know the official release date. We also don’t have many details regarding the GT350 or any other Shelby badged or special edition models.
