The tC is powered by an all-new 180-hp 2.5-liter four-cylinder engine, paired with a six-speed manual transmission; a six-speed automatic with manual shift mode is optional, while a new electronic power-assist steering system contributes to increased fuel efficiency. It is offered in one well-equipped trim level, with features that include a panorama sunroof, 18-inch alloy wheels, air conditioning and cruise control, as well as power windows, mirrors and door locks. The tC's Pioneer audio system includes a 160-watt head unit, separate 140-watt two-channel amplifier, MP3 capability and direct iPod connectivity, along with a regular auxiliary jack for other types of portable music devices. Standard safety features include eight airbags, four-wheel anti-lock disc brakes with brake assist, tire pressure monitoring and a first aid kit. New for 2011, stability and traction control systems are now standard, along with a knee airbag for the front passenger as well as the driver. The Scion tC is completely redesigned for 2011, boasting a more powerful engine with improved fuel economy, new transmissions and enhanced safety equipment. A bolder, more aggressive exterior and upgraded cabin round out the changes for this model year.
