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.
