Buick’s NAIAS Avenir concept has morphed into the production version of the all-new 2017 Buick LaCrosse, revealed for the first time in L.A. Due to begin arriving in early summer, the 2017 LaCrosse features a bold grille highlighted by a wing element that spreads out from Buick’s traditional tri-shield logo. Liberal application of high-strength steel has lightened the LaCrosse by 136 kg compared to the current model. Powering the LaCrosse is GM’s second-gen 3.6L V6 (305 hp / 268 lb-ft) mated to an eight-speed automatic transmission.
