The National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) haven't crash tested the 2014 BMW 4-Series yet. Though it's related to the 3-Series, which earned a Top Safety Pick award from the IIHS, it's not clear how much of the 4-Series' crash structure is common to the sedan--or if it will share the 3er's "marginal" score on the IIHS' new small-overlap crash test.
The 4-Series' standard safety equipment includes a full suite of airbags, stability and traction control, adaptive brake lights, and anti-lock brakes. The 4-Series also includes an Automatic Collision Notification system that relays to emergency responders detailed information on the type of accident and likely level of trauma. Bluetooth is standard, too, but a rearview camera is an option on the more basic models--even though they're priced above $42,000.
Add-ons that can crank up the 4-Series' safety margins--and its sticker price--include a rearview camera and park distance sensors; a surround-view camera system with a top view and a bird's-eye view of obstacles approaching at low speeds; and full-LED headlamps with automatic high beams. Optional blind-spot monitors are coupled with a lane-departure warning system include a camera-based collision-warning system with braking capability. Active cruise control is also offered, and it has the ability to stop the car, and to restart and carry a slow pace with traffic. Parking assist is a feature we'd pass on; the novelty of letting the car parallel-park itself wears off after a few demonstrations to friends.
We'll update this section when crash-test results are published.
