No automaker has posted a larger fleet-wide gain in fuel economy in the past five years. According to the Environmental Protection Agency, Ford’s combined car and truck fuel economy has improved nearly 20 percent since 2004 – almost double the next closest competitor.

Additionally, Ford’s tailpipe CO₂ emissions are declining. Ford’s 2009 fleet-wide average is down approximately 9 percent from 2008.

On the heels of these achievements, Ford will introduce nine new or upgraded engines and six new transmissions in North America in 2010. This is part of a five-year effort to overhaul the entire global powertrain portfolio.

The push began in 2008 and continues through 2013 and includes 60 new or significantly upgraded engines, transmissions and transaxles globally over the five-year period.

In 2010, Ford will launch new engines and transmissions in Fiesta, Mustang, Super Duty and F-150. These new powertrains are expected to propel each vehicle to best-in-segment in fuel economy.

Fiesta’s Ti-VCT 1.6-liter engine and PowerShift dual-clutch transmission will deliver a projected 40 mpg on the highway, topping both Honda Fit and Toyota Yaris.

Mustang’s new Ti-VCT 305-horsepower, 3.7-liter V6 delivers the class-leading performance and projected fuel economy Mustang buyers expect. The 2011 Mustang V6 with six-speed automatic is projected to deliver 30 mpg on the highway. No other V6 powered sports coupe in the world delivers this level of performance and fuel economy, regardless of price. Click here to read more about the new Mustang V6.

Mustang GT gets a new 5.0-liter V8 that cranks out a 412 total horsepower and 390 lb.-ft. of torque, yet is projected to deliver 25 mpg on the highway – better than any competitor. For more information on the new 5.0-liter, click here.

Both versions of the Mustang get all new fuel-saving manual and automatic six-speed transmissions.

Spring also marks the arrival of an all-new Ford-designed-and-built Super Duty diesel truck engine. The 6.7-liter Power Stroke^® V8 turbocharged diesel powerhouse is expected to lead the class in fuel economy towing, hauling, horsepower and torque.

With its advanced emissions systems, the new 6.7-liter diesel engine also will run cleaner than the outgoing model. The 2011 Super Duty also gets a new 6.2-liter gasoline engine. You can read more details on this engine by clicking here.

Other new Ford powertrains coming in 2010 include an EcoBoost™ 3.5-liter V6 for the 2011 F-150. The EcoBoost 3.5-liter twin-turbocharged engine delivers the thrust and performance feel of a V8, with the fuel efficiency of a V6. Click here to read more about the Ford Ecoboost 3.5-liter V6.

By 2013, Ford plans to offer EcoBoost engines on 90 percent of its product lineup with annual volume of vehicles with EcoBoost at 1.3 million globally.

Toward the end of the year, a new 2.0-liter Ti-VCT four-cylinder for the next-generation Focus will mark the first introduction of a normally aspirated direct-injection engine to the Ford powertrain lineup. The all-new engine will launch on the 2012 Focus in North America.
