The Acura TL sedan has been treated to over 500 improvements for the 2002 model year, including an edgier front-end appearance. Less obvious are the myriad refinements, such as aerodynamic side mirrors, improved brake feel, reduced road noise, and enhanced radio reception. Standard creature comforts have expanded to include six-disc in-dash CD changer, seat memory, auto-up driver*s window, tilt headrests, and 0.8-g-capable cupholder. Best news is the addition of a Type-S model with 260-horsepower, sporty suspension, and minor styling differentiation.
