The 2014 X5's three engine choices provide varying degrees of power and efficiency. Even a "base" X5 with the turbocharged inline-6 is a quick beast, launching the midsize utility vehicle...
... to 60 mph in the 6-second range. Choose the thunderous, thirsty V8 with its 445 horsepower and nearly $70,000 price, and you're looking at sub-5 seconds. Our pick, however, is BMW's turbodiesel 6-cylinder. It offers a fine balance of power and fuel economy, and only costs $1,500 more than a comparable gasoline-powered version. Whichever X5 you choose, you'll be treated to a larger utility vehicle that feels more like a sports sedan
. The X5 is one of the few SUVs that's fun to fling around corners, though it's less adept on tougher off-road trails. It can climb snow-covered roads without drama, but steep off-road inclines are not its forte, as we discovered after brushing its lower lip at a Canadian off-road track.
