Don't confuse the new Euro-styled Transit van -- the big brother in a growing family of commercial vans from Ford -- with the smaller Transit Connect Wagon and Transit Connect Van. The larger Transit van marks the official end of the Econoline, a Ford nameplate marketed since 1961. By the end of the year, Ford plans to be churning out thousands of Transit vans at a renovated Kansas City plant. Ford will offer a standard 3.7-liter V-6 engine, the same 3.5-liter EcoBoost engine used in the Ford F-150, and an all new 3.2-liter Power Stroke Diesel. Ford says the smaller gas and diesel engines will deliver a 25 percent improvement in fuel economy. A kit for compressed natural gas will also be offered.
