It's hard to determine where to put this, auto industry news or alternative fuel news.
Mercedes sprinter offering the 2.1L crd to US market.
The 3.0Lcrd 188hp 325lb-ft will still be available with 6sp auto, but the 2.1L 161hp 265lb-ft 1400-2400 rpm 7sp auto will be new to the line up.
Promaster with the I-4 3.0Lcrd will have it's hands full competing with MB. Let alone the Ram C/V.
Unless the Ram C/V / caravan/ town & country comes out with a 2.0L-2.2L crd + 8sp there doesn't seem to be much hope for this model other than people do not need a huge Sprinter.
The Sprinter article in autoblog also talks about a supercharged I-4 gas motor and CNG briefly. But no details.
Truck trend article
points out the 2.1L crd puts out more than the older 5cyl 2.7L crd. Plus the fuel mileage is suppose to be around 37mpg ish for the 8600 GVWR sprinter.
Plus they spill that the I-4 supercharged motor is a small 1.8L 156hp unit. 6sp manual or 7sp auto.
Sprinter also is lowered to ease loading & climbing in the cab, lower drag = better fuel economy.
