Vehicle Overview

Buick brings back one of its well-known nameplates — Regal — for its new entry-luxury midsize sedan. Based on the Opel Insignia from Europe, the Regal has a striking resemblance to that model. It's offered with a choice of four-cylinder engines, one of which is turbocharged, and it hits dealerships in the second quarter of 2010. Competitors include the Volkswagen Passat and Acura TSX.
