Freshened audio systems that include steering-wheel controls mark the 2006 tC. This 2-dr hatchback coupe comes from Toyota's youth-oriented Scion division. It has a 160-hp 4-cyl engine and a 5-speed manual transmission or optional 4-speed automatic. Antilock 4-wheel disc brakes and a driver knee airbag are standard. An option includes front side airbags and curtain side airbags that cover both seating rows. Traction/antiskid control is unavailable. The tC's front-passenger seatback reclines to form a long surface in tandem with a split folding rear seat. Newly available are audio systems that connect with and can control digital media players. Dealer-installed options include 18-inch wheels and special trim items.
