The sport utility vehicle became an endangered species not long after fuel prices began to skyrocket. But while vehicle buyers changed their shopping habits, they didn't actually stray that far from the SUV formula. Many of today's hottest-selling vehicles are crossovers; essentially the same tall wagons as the SUV, but with a lighter unibody chassis.

Among other things, the CUV promised to deliver superior efficiency, and while some improvement has been evident, in many cases, the genre's fuel savings have failed to impress. A good case in point is the Ford Edge. When Ford's two-row CUV entered the market in 2007, it managed only 24 miles per gallon on the highway, and many buyers struggled to hit 20 mpg in mixed driving cycles. There were plenty of reasons for its unimpressive efficiency. Most crossovers remain substantially heavier than a comparable four-door sedan, and with plenty of frontal area, they don't exactly slice through the wind. But perhaps the biggest issue has been unevolved powertrains.

Ford thinks it has the answer to that problem in the form of its new EcoBoost 2.0-liter four-cylinder engine. Ford is using the compact, turbocharged mill in a variety of crossovers, including the 2012 Ford Edge, and we sampled a well-equipped Edge Limited to see how effective the Blue Oval's engine downsizing strategy is going.

Our Dark Blue Pearl Metallic tester in Limited trim carried a base price tag of $34,915 that rises to $35,910 by ticking the EcoBoost option box. Ford doesn't mess around when it comes to the Limited trim: Standard accoutrements include leather-trimmed and heated seats up front, a 10-way power driver's seat, dual-zone climate control, SYNC infotainment, a 390-watt Sony sound system, back-up sensors and a rear view camera.

Our Edge was also packed with some of Ford's top options, including the 2.0-liter EcoBoost upgrade, Ford's excellent navigation system ($795), and BLIS blind-spot detection ($485). This Edge Limited also included the Drivers Entry Package ($895), which adds remote start, push-button start and a power rear lift gate. Also making the scene was Ford's much-maligned MyFord Touch system – in this guise, it includes a pair of 4.2-inch LED screens in the gauge cluster and five-way steering wheel controls. With all options present and accounted for, our tester came in at $38,910.

The draw for this Edge Limited is the 2.0-liter EcoBoost four-cylinder engine, which is a $995 option compared to the capable and relatively efficient 3.5-liter V6. The extra coin will deliver 240 horsepower and 270 pound-feet of torque mated to a smooth-shifting six-speed automatic transmission. That isn't as much punch as the 285 horsepower 3.5-liter V6, but the real story comes with a twist – the turbo 2.0 boasts 17 more lb-ft than its bigger, naturally aspirated brother, and it arrives in full force at 3,000 rpm (the V6's torque doesn't max out until 4,000 revs).

That extra pull is evident from behind the leather-wrapped steering wheel. The EcoBoost four provides good straight-line acceleration, with a 0-60 time that we estimate to be just over seven seconds. The EcoBoost also weighs a bit less, tipping the scales at 3,998 pounds – 58 fewer pounds than a front-drive V6 model. With torque that comes on early in the revband, the EcoBoost feels even quicker than any instrumented testing might suggest – at least until hitting the freeway. When we tested the V6-equipped Edge about a year ago, passing acceleration felt a bit stronger at highway speeds. The boosted four-cylinder also doesn't sound quite as pleasant as the V6, but noise levels aren't obtrusive.
