The Sprinter design is sold through several different brands; even Freightliner has a version in the US. M-B is a big name for truckers in Europe - but not the US, so the marketing identities handled differently. It's a Dodge Sprinter in the US.
I've also seen some mid-size Class C motorhomes based on the Sprinter, but Ford and GM still own most of that market.
Sorry, no diesel Chrysler Voyager available in the US.
When will the US finally get the good diesels?
