Facelifted for 2011, the BMW X5 goes on sale in May 2010, with a couple of new engine options and updated exterior styling. Well-heeled dads who don't like to make frequent stops might consider the diesel version, the BMW X5 xDrive35d, an all-wheel-drive model with a 3.0-liter, six-cylinder, turbocharged diesel engine. It gets 26 mpg on the highway, about 24 percent better than the six-cylinder gasoline model. That gives the diesel a range of close to 600 miles between stops -- assuming your passengers can hold out that long.
