2011 Mustang Engine Information – 227 cubic inch V6 (3.7L Ford Duratec V6)
The Duratec V6
In 2011, the 3.7 Cyclone V6 became a standard engine in the Ford Mustang replacing the 4.0L Cologne V6. It was commonly known and marketed as the 3.7L Duratec V6. The 3.7L Duratec has a cast aluminum alloy cylinder block with contemporary architecture. It has a removable rear main seal cover plate and a structural rear sump cast aluminum oil pan. All Cyclone engines have the same 86.6 mm (3.41 in) stroke. The additional displacement comes from an increased bore size by 3.0 mm comparing to the 3.5-liter version.
The base engine offered in 2011 was the new 3.7 liter DOHC V6 engine. It was rated at 305 hp @ 6,500 RPM and /280 lb/ft of torque @ 4,250 RPM. The ultra modern, 3.7 liter V6 was a big upgrade in every way, replacing the aging 4.0 liter Cologne overhead-cam V6 that could trace its lineage all the way back to 1962. The engine had all-aluminum construction, dual-overhead cams with twin independent variable camshaft timing (Ti-VCT), 4-valves per cylinder and a tuned X-pipe dual exhaust the Cyclone V-6 in Mustang tune boasts an unbelievable 305-horsepower and 280 pound-feet of stump pulling torque.
To put this into perspective these numbers are comparable to V-8 powered GT Mustangs from the recent past and very close to the power ratings of Cobra’s from a decade earlier! Even more impressive is that a Mustang powered by the Cyclone V-6 could achieve phenomenal fuel economy when driven responsibly. It was very possible for the owner of a 2011 V-6 Mustang to achieve over 30-miles per gallon of gasoline while cruising out on the open road. Given the power output this is simply remarkable. Not only was this V-6 powerful and economical, it was incredibly refined, so much so it was also installed in high-end Lincolns, quite impressive.
With a new engine under the hood came a pair of all-new transmissions. Standard fair was a slick shifting Getrag MT82 six-speed manual that replaced the old five-cog unit. Optional was Ford’s extremely pleasant 6R60 six-speed automatic that could run through the gears quickly and smoothly. Unfortunately a manual mode with paddle shifters wasn’t offered with the automatic which would have been a nice addition in combination with the Cyclone V-6’s fun, rev-happy demeanor.
