BMW focused on on reducing weight, adding technology, and reducing cabin noise in the redesigned 2017 5 Series. The result is remarkably satisfying car, but one that is no longer the sporty choice of this class. Instead, it’s very plush, super quiet, finely crafted inside, frugal with fuel, and more user friendly. The all-wheel-drive 530i we tested rides comfortably and handles responsively. Its turbo four-cylinder had ample power and, paired with a smooth eight-speed automatic, delivered an impressive 26 mpg overall. The 540i uses a punchy 335-hp, 3.0-liter turbo six-cylinder that effortlessly delivers power. AWD is available, and standard on the V8-powered M550i. The 530e plug-in hybrid costs just $200 more than the 530i and can go a short distance on electric power alone. Optional active safety systems include forward-collision warning and lane-keep assist.
