Pick your high-tech, luxurious poison: efficiency or blinding quickness.
Price: Starts in the low $50,000s, but goes as high as you'd like
BMW's showed off its new 5er, which starts in the low $50,000s, and offers a hybrid (530e iPerformance) that can drive in pure electric mode. Should you be gripped more by the need for speed than for savings, the M550i xDrive is monumentally fast -- with 462hp and all-wheel drive, it'll beat a current-generation M5 off the light -- but it's, um, not priced in the $50,000 range. All of the 5-Series models offer BMW's latest safety features like Lane Change Assistant, which will actively steer you back when you try to change lanes without looking, and Active Cruise Control, which monitors the current speed limit and adjusts accordingly, within an acceptable range that you control (i.e., it will speed a little, if you say it's OK). On the inside, the revamped interior benefits from gesture control, which means you don't have to actually touch the dashboard to make adjustments.
