BMW isn't taking any chances with its reputation for dynamics with the 7 Series Active Hybrid. To its 449-hp and 479-lb-ft 4.4-liter twin turbo V8 heart it adds a 60-pound, 35-cell lithium-ion battery in the boot. The battery doesn't take too much away from the trunk since it replaces the rear-seat air-conditioning unit from the standard 7.
The battery boosts maximum torque to 516 lb-ft when everything is really humming, and that gets the huge-ish hybrid to 60 in 4.9 seconds rowing through the eight-speed automatic. The battery, a judicious foot, and hybrid stalwarts like brake energy regeneration can get you 25 mpg. Until Brad and Angelina finish with their Hydrogen 7, this is your best bet for a caring Bavarian luxo-barge.
