Ford Explorer

From Ford press: The 2011 Explorer with V6 power is expected to deliver more than 20 percent better fuel economy than the 2010 model, shattering conventional expectations for SUV fuel efficiency. When equipped with the available 2.0-liter EcoBoost I-4 engine, Explorer fuel economy is expected to improve by more than 30 percent and exceed the 2010 Honda Pilot and 2010 Toyota Highlander V6.

Chief Nameplate Engineer Jim Holland said the team targeted two key objectives when developing the 2011 Ford Explorer. “It had to look modern and contemporary – inside and out – yet be instantly recognizable as an Explorer,” said Holland. “Next, the new Explorer needed to deliver the fuel economy today’s customers want, combined with the performance, capability and empowerment they expect from an SUV.”

Weight reduction is a key element in improving Explorer fuel efficiency. While adding significant content to the vehicle, engineers were able to reduce total vehicle weight by almost 100 pounds through the use of lighter materials such as an aluminum hood. Explorer weight loss is even more impressive, as the latest versions of Honda Pilot and Toyota 4Runner have added pounds versus previous models.

Explorer’s available advanced 2.0-liter EcoBoost I-4 delivers the power of a normally aspirated V6 without compromising four-cylinder fuel economy. Aimed at the SUV buyer whose top priority is fuel economy, this turbocharged and intercooled I-4 engine delivers a projected 237 horsepower at 5,500 rpm and 250 lb.-ft. of torque from 1,700 through 4,000 rpm. The EcoBoost employs direct injection of gasoline, Ti-VCT, direct-acting mechanical bucket (DAMB) valve lifters and four valves per cylinder.

Explorer’s standard powertrain combines front-wheel drive with a 3.5-liter Ti-VCT V6 engine, delivering an estimated 290 horsepower and 255 lb.-ft. of torque. Ti-VCT allows individually optimized camshaft timing of valve opening and closing events to improve mechanical efficiency while delivering increased power and reducing part-throttle emissions.

Mated to a six-speed automatic transmission, this powerful, flexible and efficient V6 is projected to deliver more than 20 percent better fuel economy versus the previous Explorer V6 model.

Explorer’s variable-displacement air-conditioning compressor provides a fuel economy benefit with less drag and smoother transition for improved driveability. Each Explorer engine is paired with a unique six-speed automatic transmission, combining lowered initial gears for improved off-the-line acceleration and higher gearing for improved efficiency at lower engine rpm when cruising.

Explorer V6 models are available with an intelligent 4WD system that adds terrain management. Situation-selectable, this powertrain advancement takes the guesswork out of 4WD range choice.
