The 2010 Buick LaCrosse is an interesting experiment in cross-cultural fertilization, having been designed by teams of engineers and stylists collaborating via computer from studios in Shanghai and Detroit. The LaCrosse boasts a sharp exterior design and an elegant interior, offering neat stitching on seat covers not usually associated with General Motors cars. The LaCrosse is powered by a V6 engine equipped with both direct injection and variable valve timing that increases fuel-efficiency.
