Mercedes 2.2L turbodiesel
Mercedes has been hard at work developing new versions of diesel engines to meet the Euro 5 emissions standards, due to take effect with the 2010 model year. The latest model is new 4 cylinder turbo diesel design called the 220 CDI that produces about 175 hp and 300 lb-ft. This engine will be available in the Mercedes C Class and E Class in late 2009, so taxis all over Europe will be using it.
It's likely that Chrysler will replace the 2.8L diesel sourced from VM Motori with this new 2.2L model for Chrysler products sold in Europe. These include the Chrysler van, the 300 sedan, and several Jeep models. So there's an outside chance that this new engine will appear as an option in Chrysler products sold in North America.
If it's true that the 3.0L V6 turbo diesel is too wide to fit easily in the Wrangler, then this four cylinder model is the engine we're likely to see in a JK. Hopefully it will be cheaper to buy, too.
