Straddling the family- and upscale-sedan categories, the TSX is based on the smaller European-sold version of the Honda Accord. Modest power keeps it from being as exciting to drive as the best sports sedans, but agile handling and a slick manual gearbox help. Our major beef is the stiff ride. Fuel economy is good at 23 mpg with the smooth five-speed automatic, but the car requires premium fuel. Interior fit and finish are impressive, but the cabin is relatively snug. Controls are logically arranged, including the optional touchscreen navigation system. Stability control is standard, which is impressive for the time. Comprehensive standard equipment includes leather and a sunroof.
