The 7-series comes in 740 and 750 models. The 740 sports BMW's 4.4-liter four-cam 32-valve V-8 engine. Horsepower is rated a robust 282. The 7-series is precisely the kind of car you want to put your family in. It feels as strong and safe as your average bank vault. With six air bags - and 2 more as options - in addition to traction and stability control systems, it seems unthinkable that a driver or passengers could get seriously injured in anything short of a freak accident or natural disaster - such as an airplane crashing on the car or the ground disappearing from underneath it.
