The 2009 Buick Lucerne sedan will join General Motors' industry-leading lineup of flex-fuel vehicles that can run on either ordinary gasoline or E85, or any combination of the two, GM Vice President of Environment, Energy and Safety Policy Beth Lowery said Thursday.

Buick will offer two new safety-enhancing technologies that could serve as an extra set of "eyes" for drivers, helping them to avoid a collision caused by an inadvertent lane change or by colliding with a vehicle in the side blind spot while changing lanes. The technologies will be available on all 2008 Buick Lucerne sedan models this summer.
