Buick is looking to be cool again as it introduced the elegant-looking Avista sports coupe concept at an auto show in Detroit.<br />The Avista is a 2 + 2 coupe concept that runs a twin-turbo charged V-6, which can notch up 400 horsepower, thanks to an eight-speed auto transmission.<br />If this sounds familiar, it is because the Avista has adopted several design sensibilities from the Avenir, which Buick debuted in 2015 in Detroit.<br />"The Avista embodies the dynamic soul of Buick.<br />It is a modern expression of the brand's heritage of sophisticated performance, communicated with beautiful elegance," says Duncan Aldred, vice president of global Buick sales, service, and marketing.
