Two TL flavors will be offered, confirming the preview report that ran on Autoblog in April. Honda doesn't announce powertrain specifics other than to confirm that the new TL will be available with Acura's SH-AWD system and also offer the marque's "most powerful engine ever." We assume that to mean the 300-horsepower 3.7L engine used in the RL and MDX will also be making an appearance in the TL. Based on what we were told back in April, look for a 280-horsepower 3.5L to serve as the base engine in the FWD car.Source; http://www.autoblog.com/2008/07/11/2009-acura-tl-shows-its-face-awd-confirmed/
