For 2009, the 2010 model year Fusion and Milan will offer Ford's all-new Duratec 2.5-liter I-4, producing 175 horsepower; an enhanced 3.0-liter V-6 with 19 more horsepower than its predecessor; and a 3.5-liter V-6 that pumps out 263 horsepower on the Fusion Sport model.
The 2.5-liter I-4
First launched on the fuel-economy segment leader 2009 Ford Escape, Ford's all-new Duratec 2.5-liter I-4 gives the 2010 Fusion 175 horsepower and 172 lb.-ft. of torque, 14 more horsepower and 16 more lb.-ft. of torque than the preceding year's 2.3-liter engine.
The 2.5-liter uses intake variable cam timing (iVCT) technology to optimize valve timing, creating a broad torque curve that helps deliver increased power along with improved efficiency.
The powertrain also incorporates electronic throttle control (ETC), dual-mode crankshaft damping, new intake and exhaust manifolds, and a new underbody-only catalyst, which refine performance and contribute to greater fuel efficiency.
The 3.0-liter V-6
The improved 3.0-liter V-6 available on the 2010 Fusion delivers 19 more horsepower and 23 more lb.-ft. of torque for a total of 240 horsepower and 228 lb.-ft. of torque.
The 3.0-liter features a new air induction system and ETC as well as an industry-first Cam Torque Actuated (CTA) iVCT technology that uses available camshaft torsional energy rather than pressurized oil to phase the camshafts. This allows for a smaller displacement oil pump versus traditional hydraulic VCT systems for improved fuel economy.
"With this technology, we are taking energy that is in your engine today – energy that was previously wasted – and using it to make an engine more efficient," said Steve Wilkie, supervisor of Cam Drive/VCT Design. "The cam torque actuated technology is a significant player in the 3.0-liter's ability to provide customers fuel economy and performance."
This innovative method uses torsional energy to move the camshafts similar to the way a hydraulic ratchet works. The system takes oil from one side of the phaser and channels it to the other side, rather than draining one side and filling the other as with a traditional hydraulic system. This allows the CTA system to work more efficiently at all engine speeds and it requires a smaller oil pump, which equates to lower parasitic energy loss.
CTA reduces oil pump flow requirements by approximately 25 percent, producing a fuel economy benefit up to 0.4 percent. In addition, the CTA-based system responds more quickly than a traditional hydraulic oil actuated VCT system, improving tip-in performance feel and contributing to horsepower gains.
The 3.0-liter is also flex-fuel capable and can run on E85, helping Ford deliver on a pledge made to double annual production of vehicles capable of running on renewable fuels by 2010.
The 3.5-liter V-6
The award-winning Duratec 3.5-liter V-6 joins the Fusion lineup for 2010, powering the Sport model with a beefy 263 horsepower and 249 lb.-ft. of torque.
The 3.5-liter uses a compact, lightweight dual-overhead cam valvetrain for peak power and smooth operation at high RPMs. This engine also incorporates intake variable cam timing to optimize valve timing for a smooth idle and an impressive broad torque curve with good power. A high 10.3:1 compression ratio and aluminum cylinder heads designed for high airflow and optimized combustion help complete the package, supporting the engine's ability to deliver great performance and fuel economy, along with low emissions.
