The base TSX comes with a 2.4L i-VTEC 4-cylinder engine that delivers 201 horsepower with either a 6-speed manual or 5-speed automatic transmission. The 280 horsepower 3.5L V6 engine and 5-speed automatic transmission returns for 2011. The automatic transmission includes SportShift manual override and steering wheel paddles. The car's sporty handling comes courtesy of a special suspension that utilizes dual-mode dampers. These dampers have the ability to change automatically given road and driving conditions. A new Sport Wagon TSX variant appears in 2011. Based on the 4-cylinder TSX sedan, the wagon brings the refinement, handling and subtle styling of the sedan, but adds 30 cubic feet of cargo in back. Standard equipment on all TSXes includes a power moonroof, xenon HID headlights, heated front seats, leather upholstery, automatic climate control, satellite radio and HandsFreeLink (Bluetooth) wireless connectivity. Safety equipment includes 4-wheel antilock brakes, Vehicle Stability Assist with traction control, a tire pressure monitoring system and front side-impact airbags, overhead curtain airbags and new active anti-whiplash front head restraints. The optional Technology Package, available on both the sedan and wagon models, includes a navigation system with voice activation and real-time traffic and weather, integrated rearview camera parking assist, a 10-speaker and a 415-watt surround-sound audio.
