Every since the Lexus GS first hit the scene, it has remained among the top mid-size luxury sedans. With the arrival of a new turbocharged four-cylinder engine, the GS can now return a pleasing 33 mpg. However, even the potent V-6 engine proves to be easy on gas. Lexus engineered the optional sports-tuned suspension to instantly adjust to imperfections in the pavement. In terms of styling, a spindle grille helps the GS to make a grand entrance. Featuring sportier exterior trim and a racy set of wheels, the F Sport package gives the GS a macho appearance. Pedestrian detection and automatic braking technology are also offered.
