The main reason diesels aren't offered here (gov't bee essence aside) is that Americans haven't demanded ANY kind of high MPG cars until now. So only now are manufacturers (VW and M-B aside) considering offering diesels, but now they are having trouble meeting stricter emissions regs.
For instant higher MPGs, the no-brainer would be to offer smaller gas engines in the existing lineup, but this hasn't even happened here. Consider the Camry, Accord, and Altima: Even though each company makes nice small engines, the smallest available engine is a 2.4 or 2.5 liter. In Europe, one can get a 1.6 liter gas engine in an Audi A4 (along with 3 diesel options - doh!), for example, and most other mid-sized cars are also available with small engines, gas and diesel.
The simple truth is that the average American car buyer simply doesn't care enough about fuel economy yet. (And those few who do are forced to get a hybrid or a subcompact.) Gas prices just aren't high enough! Yesterday, they said on Marketplace that the adjusted price of gas in the US is the same as it was in 1982.
By the way, I noticed you can get a new M-B M-class (SUV) diesel now, along with the E-class.
