While Acura's TL has only been on sale since the 2009 model year, it appears Acura engineers are prepping an updated model.
The "Power Plenum" grille featured on the TL has been nothing short of controversial, and it appears that is where the bulk of the changes will occur on the updated TL. Given the instrumentation attached to this prototype, some modest powertrain updates may also be in the works.
Watch for the official debut sometime this fall.
