Ford F-150 Ecoboost

Ford hit a milestone with its F-150 pickup last month. According to PickupTrucks.com, the Blue Oval sold more trucks with V6 engines than V8 mills. Forty-one percent of F-150 sales left the lot with the company's 3.5-liter Ecoboost six-pot under the hood. That number is up four percentage points compared to last month.

Additionally, the base, naturally-aspirated 3.7-liter V6 engine took home a 14 percent slice of the total mix, bringing the grand V6 total to 55 percent of all F-150 sales. The news comes as little surprise to anyone who's spent time in the full-size truck.

The twin-turbocharged, direct-injected 3.5-liter EcoBoost V6 engine provides more power and better fuel economy than the 5.0-liter V8 alternative. While it carries a $750 premium over the larger displacement engine, buyers are keenly aware of just how much a few extra mpgs can save at the pump. As PickupTrucks.com points out, fuel prices are currently a dollar higher right now than they were at the same point last year.
