Ford is using the 2008 Detroit Auto Show to kick off the transition of a significant portion of their engine lineup to what they are calling EcoBoost technology. EcoBoost consists of smaller displacement engines with direct fuel injection and turbocharging (GDTI) to provide a fuel economy boost without any loss of performance. Ford first showed the idea in the 2007 Lincoln MKR concept when it was called Twin-Force. The Twin-Force name has been set aside in favor of one that emphasizes the efficiency aspects of the technology. Thanks to the combination of small low-inertia turbos, the direct injection and variable valve timing, the new engines should have no lag and a much fatter, flatter torque curve.

The first EcoBoost engine out of the gate is the 340hp 3.5L V-6, This will be the optional engine in the Lincoln MKS starting in 2009 in place of a V-8. Besides having higher specific efficiency than a larger normally aspirated engine, the smaller EcoBoost units also save weight and size. The 3.5L saves over 150 lbs. compared to the 4.6L V-8 also helping contribute to fuel efficiency savings of up to 20%. Following the MKS with EcoBoost will be the Ford Flex and the new Explorer based on the Explorer America concept. The new SUV is expected to use GDTI engines exclusively, with a 275hp 2.0L four as the base engine and the 3.5L six as the option. Ford is by no means the first to do this, with Volkswagen pushing the tech for several years already on their TSI and TFSI engines. aMazda and GM also use the same principle. Ford really wants to make it mainstream, however, with over half a million EcoBoost engines annually within five years. Read more about EcoBoost over at AutoblogGreen.

FORD TO EQUIP HALF A MILLION VEHICLES WITH ECOBOOST ENGINE TECHNOLOGY FOR UP TO 20% BETTER FUEL ECONOMY


DETROIT, Jan. 6, 2008 – Ford Motor Company is introducing a new engine technology called EcoBoost that will deliver up to 20 percent better fuel economy on half a million Ford, Lincoln and Mercury vehicles annually in North America during the next five years.

The EcoBoost family of 4-cylinder and 6-cylinder engines features turbocharging and direct injection technology. Compared with more expensive hybrids and diesel engines, EcoBoost builds upon today's affordable gasoline engine and improves it, providing more customers with a way to improve fuel economy and emissions without compromising driving performance.

"EcoBoost is meaningful because it can be applied across a wide variety of engine types in a range of vehicles, from small cars to large trucks – and it's affordable," said Derrick Kuzak, Ford's group vice president of Global Product Development.

"Compared with the current cost of diesel and hybrid technologies, customers can expect to recoup their initial investment in a 4-cylinder EcoBoost engine through fuel savings in approximately 30 months. A diesel will take an average of seven and one-half years, while the cost of a hybrid will take nearly 12 years to recoup – given equivalent miles driven per year and fuel costs," he said.

Ford will introduce EcoBoost on the new Lincoln MKS flagship in 2009, followed by the Ford Flex and other vehicles. By 2013, Ford will have more than half a million EcoBoost-powered vehicles on the road annually in North America.

In 2009, Ford first will introduce EcoBoost on the Lincoln MKS featuring a 3.5-liter twin-turbocharged V-6. It will produce the power and torque of a V-8 engine with the fuel efficiency of a V-6. In fact, with an estimated 340-horsepower and more than 340 lb.-ft. of torque, the Lincoln MKS will be the most powerful and fuel-efficient all-wheel-drive luxury sedan in the market.

More With Less
EcoBoost's combination of direct injection and turbocharging mitigates the traditional disadvantages of downsizing and boosting 4- and 6-cylinder engines, giving customers both superior performance as well as fuel economy.

With direct injection, fuel is injected into each cylinder of an engine in small, precise amounts. Compared to conventional port injection, direct injection produces a cooler, denser charge, delivering higher fuel economy and performance.

When combined with modern-day turbocharging – which uses waste energy from the exhaust gas to drive the turbine – direct injection provides the best of both worlds: the responsiveness of a larger-displacement engine with fewer trips to the gas pump.

Ford's 3.5-liter EcoBoost V-6, for example, can deliver upwards of 340-plus lb.-ft. of torque across a wide engine range – 2,000 to 5,000 rpm versus 270 to 310 lb.-ft of torque for a conventional naturally aspirated 4.6-liter V-8 over the same speed range. At the same time, this V-6 gives customers an approximate 2 mpg improvement and emits up to 15 percent fewer CO2 emissions to the environment.

Direct injection coupled with turbocharging allows for the downsizing of engines that deliver improved torque and performance. A small 4-cylinder EcoBoost engine has the capability of producing more torque than a larger 4-cylinder engine – nearly an entire liter larger in displacement – with better fuel efficiency.

The real-world fuel economy benefit is consistent no matter the drive cycle, meaning the engine is efficient in the city as well as on the highway – unlike hybrids, which are most efficient in stop-and-go traffic. In addition, customers who tow and haul – and have long turned to more expensive diesel powertrains for their superior towing capabilities – can find the engine performance they need from an EcoBoost powertrain.

EcoBoost – combined with multi-speed transmissions, advanced electric power steering, weight reductions and aerodynamic improvements – is part of Ford Motor Company's strategy to deliver sustainable, quality vehicles that customers want and value. Additional hybrid offerings and diesel engines are planned for light-duty vehicles.

Longer term, Ford plans to remain aggressive in the development of plug-in hybrids and hydrogen fuel cell-powered vehicles.

"We know that what will make the biggest difference is applying the right technology on volume vehicles that customers really want and value and can afford," said Kuzak. "EcoBoost puts an affordable technology within reach for millions of customers, and Ford's systems approach adds up to a big idea that differentiates Ford's sustainability strategy in the market."
