Acura's largest car gets a makeover for 2009. No, the RL still doesn't have a V8, but it does get a bigger V6 (3.7 liters and 300 horsepower) coupled to a standard all-wheel-drive system. The exterior has been updated and the interior gets a once-over, with more room for back seat passengers and -- I'm quoting from the press release -- "easier-to-use front seat belts".
