Despite those incremental improvements, the centerpiece of the 2011 Mustang is obviously the 24-valve Duratec V6, and it includes Twin Independent Variable Camshaft Timing (Ti-VCT) and polished buckets and roller finger followers in the direct-acting mechanical bucket valvetrain, among other features. Ford officials promise that V6 buyers won't miss the roar of the V8's extra cylinders thanks to a retuned air intake and throaty standard dual exhaust. At the sneak-peek event for this new Mustang motor, Autoblog had the chance to hear the new engine fire up and rev – and it indeed sounds sporty and purposeful. To be fair, however, we only heard the powertrain briefly in an enclosed space (a large development garage on Ford's Dearborn campus), so we'll have to wait until it's out in the open and we're behind the wheel to really get a feel for the 3.7's aural character. Other noteworthy features of the drivetrain include a deep-sump aluminum oil pan that enables less-frequent 10,000-mile oil change intervals and a 7,000-RPM redline.
On the transmission front, Ford has fitted a new six-speed 6R60 automatic (with a special hill assist mode that reduces gear hunting) that allows for the 30 MPG highway bogey, as well as 19 MPG in the urban cycle (a 25 percent improvement over the 2010's 16 mpg city / 24 mpg highway figures). Prefer to shift for yourself? Expect fuel economy to suffer an iota for your enjoyment, with numbers for the six-speed manual falling to 18/29 (2010 MY: 18/26).
Naturally, with an all-new powertrain and its differing weight properties, Ford's engineers also had to turn their attention to the suspension. To that end, the 2011 V6 gets new damper and spring rates, a different rear lower control arm, and stiffer stabilizer bar bushings
