I was hustling along a two - lane hilly road and thought I was doing about 70 mph but looked down to discover that the needle was hovering at the 100 - mph mark.
I used our turbocharged Sonata for a 150 - mile round trip through the Detroit metro area, driving it on surfaces ranging from narrow, highly crowned, hilly gravel roads; to suburban four - lane boulevards; to crowded urban freeways.
