At the 2008 Detroit Auto Show, Acura showed off a new 2.2-liter four-cylinder diesel engine and announced it would debut a production version in 2009. Informed speculation says that the oilburner would be equipped in the new TSX, a re-badged version of the European Honda Accord that currently offers the engine. Honda engineers have even presented documents outlining the new exhaust developed for the engine in the last two editions of the Society of Automotive Engineers World Congress.

Acura is in the middle of a total makeover, and while we've already seen the RL and TSX, the Japanese automaker's bread and butter TL has been out of the spotlight, until now. Spy photographers have snapped up a couple shots of the 2009 TL sans the requisite crazy patterns and without most bras, leaving some poorly fit panels to throw us off.
