The Buick brand has been undergoing a transformation over the last few years, and they're counting on the LaCrosse sedan to revamp its image. To appeal to consumers looking for luxury, Buick even developed the Avenir, a new high-end version with more comprehensive equipment and a more meticulous interior finish. A 2.5-litre engine with a mild hybrid system delivers 194 hp and a fuel efficiency of 6.7 L/100 km on the highway, while a 310-hp V6 and all-wheel drive are also available.
