I had the rare opportunity yesterday to take a ProMaster diesel 2500, Cargo Van, Long (159") WB high roof, 236" OAL for a lengthy spin courtesy of my neighbor whom is a senior engineer working on finalizing that very truck for production. I first seen this vehicle about a month ago in his driveway and was very intrigued by the shape and size. I have been in the market for a replacement of the ever so small 2500 express that I own. The diesel/auto manual is quite impressive. The first gear winds up quick but I have to say the overall speed was impressive but there was no load either. The ride was incredibly smooth and at 80mph it had not even began to labor the engine. The inside was crazy big and now I can't get one soon enough to replace the knee killer express I drive. The cab is very forward and that may take some getting used to for some coming from a van. The turning radius could not be better on a big van like this. I managed to turn 180 over 3.5 parking spaces between my drivers door. The diesels will not be available until march 2014. My neighbor claims there should be no problem getting 25mpg out of it with the 1500lbs of weight I would carry (mostly tools and none too heavy) My express under the drive I take every day yields about 14mpg at it best. I can't say enough good about this truck so far. I will be taking another trip soon. I can't wait to order my own.
