NEW SCION "TC"CUSTOMIZEDAs for what's new, the engine is now a "2.5-liter I-4", up from 2.4 liters. Power is up as well. The new tC ships with a respectable 180 horsepower and 173 pound-feet of torque. That's plus 19 ponies and 11 pound feet. The suspension is now "sport tuned" and the power steering is electronic, which Scion assured us better allows the engineers to dial in more steering feel. Uh-huh.The new tC also gets better gas mileage than the previous car (no word yet on exactly how much better) and comes with two new transmissions. There's a six-speed AUTOMATIC that features sequential-shift (Scion-speak for a manual shift mode) as well asa six-speed manual that promises more refined shifting than the old five-speed. Other goodies include 18-inch wheels and larger tires, bigger brake rotors (Scion claimed 16-inch rotors front and back during the press conference, but that's... insane) and a flat-bottom steering wheel.
