Ford has officially announced that it will debut an all-new V6 engine for the 2011 Mustang at the LA Auto Show later this week. The new engine is smaller, displacing just 3.7-liters compared to the old 4.0-liter mill, but power is up significantly. In fact, power is way up with the new motor getting a bump from 210-hp to 305-hp! Torque is up too, by 40 ticks to 280 ft-lbs. Full power comes on at 6500 rpm with full torque at 4250 rpm. Plus, Ford says the new engine will deliver 19/30 mpg (city/highway) with a six-speed automatic or 18/29 mpg with a six-speed manual. Yup, finally a six-speed for the Mustang.

And as though all this we’re good enough, the all-aluminum block weighs less than the old 4.0-liter engine.

To achieve all these improvements, the motor uses Ford’s Twin Independent Variable Camshaft Timing (Ti-VCT). Essentially, this is the same engine that Ford first used in the Lincoln MKS.

Perhaps most importantly, however, is the fact that this new engine trumps that found in the new Camaro – by 1-hp. That certainly isn’t much, but by being able to make the claim is certain to help Ford win back some sales from Chevy. And in Ford’s smaller and lighter package, performance will no doubt put the Mustang ahead of the Camaro.

As exciting as this new V6 engine news is, we are still awaiting confirmation from Ford on an all-new 400-plus horsepower 5.0-liter V8 engine for the Mustang GT. Be sure to follow AutoGuide’s live LA Auto Show coverage starting December 2nd.

TWIN INDEPENDENT VARIABLE CAMSHAFT TIMING (TI-VCT) HELPS MAKE 2011 FORD MUSTANG V-6 A TRUE THOROUGHBRED

  • Ti-VCT technology key to Mustang’s new 3.7-liter V-6 engine’s flexibility, delivering 305 horsepower and a projected 30 mpg highway with six-speed automatic transmission – no other vehicle in the industry can beat that combination
  • Variable camshaft timing uses oil pressure to adjust valve opening and closing events, providing improved off-the-line acceleration over non-VCT equipped engines
  • Variable valve overlap from Ti-VCT provides better fuel economy and emissions, along with optimized cold-start operation vs. conventional engines

DEARBORN, Mich., Nov. 30, 2009 – The heart of every Mustang is its engine, and beneath the hood of the new 2011 Ford Mustang V-6 beats a technological tour de force. Displacing 3.7 liters, the dual-overhead-camshaft (DOHC) 24-valve V-6 uses Ford’s Twin Independent Variable Camshaft Timing (Ti-VCT) to produce 305 horsepower and 280 ft.-lb. of torque and is projected to deliver up to 30 mpg highway – a combination unbeaten by any other vehicle in the industry.

Customer benefits of Ti-VCT include extremely precise variable control of “valve overlap,” or the window of time in which both the intake and exhaust valves in the engine are open simultaneously.

“This overlap control via Ti-VCT helps us eliminate compromises in the induction and exhaust systems,” said Jim Mazuchowski, Ford manager of V-6 powertrain operations. “Drivers are going to notice improved low-speed torque and increased fuel economy and peak horsepower. Plus, there are benefits they won’t notice, too, such as reduced emissions overall, especially at part-throttle.”

The flexibility allowed by Ti-VCT means Mustang V-6 customers will experience:

  • Better off-the-line launch feel, with plenty of the low-end “grunt” for which Mustang is famous. Ti-VCT can deliver up to a 5 percent improvement in low-end torque and a 7 percent improvement in peak power versus non-Ti-VCT-equipped engines.
  • Improved fuel economy at all engine speeds resulting in projected 19 mpg city/30 highway with six-speed automatic transmission; 18 mpg city/29 highway with six-speed manual transmission. Ti-VCT alone can account for up to a 4.5 percent fuel economy improvement over non-VCT-equipped engines.
  • Lower emissions, with better control of NOx and HC throughout the range of engine operating speeds, reducing atmospheric pollution.

How the technology works
As a DOHC design, the 3.7-liter V-6 uses two camshafts per cylinder bank – one to open the intake valves and one to open the exhaust valves. Traditionally, camshafts only have been able to open the valves at a fixed point defined during engine design and manufacturing. But with modern variable cam timing systems, the camshafts can be rotated slightly relative to their initial position, allowing the cam timing to be “advanced” or “retarded.”

Ti-VCT takes this technology and applies it to both the intake and exhaust camshafts of its DOHC design, using electronic solenoid valves to direct high-pressure oil to control vanes in each of the camshaft sprocket housings. By using one valve per camshaft, controlled by the Electronic Control Module (ECM), each intake and exhaust cam can be advanced or retarded independently of the other as engine operating conditions change, providing an exceptional degree of valve timing control.

The new 3.7-liter engine for the 2011 Mustang V-6 will be built at Ford’s recently retooled Cleveland Engine Plant No. 1.

    WOW,that is REAL NICE! way to go ford!!!!

    its about time … this is exactly what competition does, it brings out higher quality cars for about the same price as before. when the camaro left the market it was bad because there was no competition. at first it was fun to beat civics at the stop light but after a while it got boring … now stop lights will be interesting again …

    Whats really amazing about the 2012 Mustang, 6 speed manual, 3.7liter engine. I bought the grabber blue base Mustang and you have to get in this car and drive it to understand the amazing feeling of the power, performance and ride. Extremely quick and agile in traffic. I can drive in 6th gear at 40mph at 1K rpm. Never had any car including a camaro which would do that. The mpg is terribly underestimated, at 60mph Ive averaged 37.8 mpg, at 70mph 34.7 mpg. But there is one universal truth, if you put your foot in it and require instant power you wont get high mpg no matter what. I get equivalent mpg in the Mustang as my wifes classical malibu which has a 4 cylinder 2.2 liter motor. The mustang is an excellent car and the 3.7 Liter has plenty of power for anyone. At 2K rpm and in 6gh gear Im moving about 90MPH, the engine isnt even beginning to strain. I havent had a ford for thirty years but take it from me the new 2012 ford line is exceptional including the Mustang. Dont buy a Mustang if you dont want to feel spoiled.
