Acura's best-selling car is redesigned for 2004 with new styling, more power, and more standard safety features. The TL is based on the platform of the Accord sedan from parent-company Honda, but is more luxurious and more expensive. The '04 TL has virtually the same wheelbase as its 1999-2003 predecessor, but overall length is shorter by 6.3 inches. Interior dimensions change little. The sole engine is a 3.2-liter V6 with 270 hp. A 5-speed automatic transmission with manual shift gate returns. Replacing the sporty Type-S model is a 6-speed manual-transmission TL version with a firmer suspension than automatic-transmission models, plus Brembo-brand front brakes and a limited-slip differential. Manual versions are available with high-performance tires vs. the standard all-season treads. All TLs come with ABS, 17-inch wheels, and an antiskid system. Front side airbags are standard and are joined for '04 by head-protecting curtain side airbags. Leather upholstery with heated front seats, aluminum interior trim, and a sunroof are standard. So is satellite radio and a new audio system with an in-dash changer that plays CDs and DVD-Audio discs. Other new features include Acura's HandsFreeLink, which employs the audio system as a hands-free, wireless link to cell phones. A navigation system with voice command is optional. OnStar assistance is no longer available.
