2011 Ford Mustang



The 2011 Ford Mustang puts 305 high-performance horses in the hands of V-6 coupe buyers with a new all-aluminum double-overhead-camshaft (DOHC) engine that delivers 31 mpg on the highway with a six-speed automatic transmission.

The all-new six-speed automatic is joined by a six-speed manual transmission for the shift-it-yourself crowd, while handling and cornering is bolstered by the addition of Electric Power Assist Steering (EPAS) and a host of suspension improvements.

“This car marks a new era for Mustang,” said David Pericak, Mustang chief nameplate engineer. “We’re adding technology and fuel economy to Mustang’s legendary reputation for handling and roadholding; it’s really going to attract a whole new group of Mustang buyers.”

New all-aluminum 3.7-liter V-6

For 2011, Mustang’s new 3.7-liter Duratec 24-valve V-6 uses advanced engineering to deliver its power and economy: Twin Independent Variable Camshaft Timing (Ti-VCT) adjusts the valvetrain in microseconds. Aluminum construction means light weight. It’s an engine designed to crank out torque down low, rev to 7,000 rpm and deliver the mechanical music sports coupe lovers crave everywhere in between.

“This new V-6 engine really speaks to what Mustang is all about,” said Barb Samardzich, Ford vice president of Global Powertrain Engineering. “It produces power everywhere in the rev range and loves to be pushed hard. The Duratec 3.7-liter builds on our promise to use advanced technology to deliver both power and fuel economy.”

The high output is due largely to Ti-VCT, which allows variable control of valve operation across the rev range. The variable cams operate on a Direct Acting Mechanical Bucket (DAMB) valvetrain using polished buckets to reduce friction. The end result is as much as a 3 percent improvement in fuel economy and a 10 percent improvement in power output versus traditional engines without these advanced features.

Ti-VCT is complemented by specially tuned composite upper and lower intake manifolds for efficient air delivery and lighter weight. Ignition power is delivered by a high-energy coil-on-plug design, while piston-cooling jets and a lightweight die-cast aluminum cylinder block improve the durability and efficiency of the 3.7-liter V-6 design.

A die-cast aluminum deep-sump oil pan provides 10,000-mile oil change intervals, saving drivers money on maintenance and resulting in less waste in oil disposal.

Engineers also worked to ensure aggressive, high-performance sounds come from the new engine, from intake to exhaust. Not only does the retuned air intake system minimize losses, it also provides the driver with a satisfying intake rush on hard acceleration. The all-new dual exhaust system is mellow at idle but opens up with a howl at full-tilt, letting Mustang drivers know they’re behind the wheel of a world-class sports coupe.
