Safety
The BMW 650i has not been crash-tested by the National Highway Traffic Safety Administration and Insurance Institute for Highway Safety. Neither organization typically tests low-volume cars with sticker prices this high.
The 650i comes with seat-mounted side airbags. Because it's a convertible, there are no roof-mounted side curtain airbags. You can see all the standard safety features here.
It also comes with an emergency telematics service — like GM's OnStar — called BMW Assist. It includes four years of collision notification, emergency request, roadside assistance and stolen vehicle recovery.
