Vehicle Overview
Redesigned last year, the sixth-generation 5 Series gained a longer wheelbase, better fuel efficiency and more conventional styling than its predecessor. Available in 528i, 535i and 550i trims, the five-seat 5 Series is offered with a twin-turbo V-8 (550i), a single-turbo six-cylinder (535i) and a new turbocharged 2.0-liter four-cylinder for the 528i, with an eight-speed automatic transmission available across the board. Competitors include the Mercedes-Benz E-Class, Audi A6 and Infiniti M.

High-tech options include BMW's Adaptive Drive system, a self-parking feature and lane departure and blind spot warning systems.

The 5 Series lineup includes the Gran Turismo, a tall hatchback built on the 7 Series sedan platform.

New for 2012
A turbocharged 2.0-liter four-cylinder replaces a normally aspirated 3.0-liter six-cylinder in the 528i and will likely show up in other BMWs as the automaker seeks to improve gas mileage. BMW's xDrive all-wheel-drive system, available last year on the 535i and 550i, is newly available for the 528i. The 528i and 535i also get standard stop-start technology in which the engine automatically turns off when the car is stopped and the driver's foot is on the brake pedal. The engine automatically restarts when the pedal is released.

Exterior
Sharing its platform with the recently redesigned 7 Series, the 5 Series' wheelbase was extended about 3 inches with the 2011 redesign. Up front, the car's signature kidney grilles sit lower and are upright. The previous 5 Series' eyebrow-laced headlights have been toned down; the eyebrows are still there, but they don't extend as far back toward the front wheels. Adaptive xenon headlights are optional on the 528i and standard elsewhere. The taillights employ three rows of LED lights, and BMW's Adaptive Brake Lights illuminate a larger section under hard braking. Exterior features include:

• 17-inch alloy wheels (528i)
• Available 18- and 19-inch rims
• Standard power sunroof, Standard heated side mirrors

Interior
Drawing cues from the 7 Series, the 5 Series' climate-control readouts use BMW's Black Panel technology to appear out of dark panels without the brightened look of traditional electroluminescent displays. Cupholders are located in the center console instead of flipping from the dashboard as on the previous generation. The optional navigation system includes a massive 10.2-inch center display with high-resolution. Without navigation, the display still sorts through various audio and setup menus, but it shrinks to a 7-inch display and 800-by-480 pixel resolution. Both setups incorporate BMW's iDrive system. Interior features include:

• 10-way power front seats, Automatic dual-zone air conditioning, Power tilt/telescoping steering column
• Optional head-up display
• Optional heated and ventilated front seats
• Optional 60/40-split folding backseat

Under the Hood
The 528i has a new 240-horsepower, turbocharged 2.0-liter four-cylinder for 2012. Meanwhile, the 535i retains a 300-hp, turbocharged 3.0-liter six-cylinder and the 550i has a twin-turbo 4.4-liter V-8 that makes 400 hp. All three use an eight-speed automatic transmission; the 535i and 550i also offer a six-speed manual. All three models are available with rear- or xDrive all-wheel drive.

BMW's Adaptive Drive system includes Active Roll Stabilization, which attempts to actively counter body roll, as well as an adaptive suspension and customizable settings for both the drivetrain and suspension. Mechanical features include:

• Optional Active Steering varies the steering ratio to render easier turning at low speeds and stable handling at high speeds
• Optional adaptive cruise control includes full stop-and-go capabilities to manage heavy traffic

Safety
Blind spot and lane departure warning systems are optional, as is adaptive cruise control with a collision warning system. Standard safety features include:

• Side curtain airbags, Side-impact airbags for the front seats
• Active front head restraints, Electronic stability system, Four-wheel-disc antilock brakes
