2012 Ford Econoline 350 w/ 5.4 = 10.9s 0-60 as verified by my telephone. Econ - ~14mpg as tested
2008 Chevrolet Express 2500 w/5.3 AWD = 10.3s 0-60 as verified the same way. Econ - 18.8mpg mixed
Neither van had wheel spin.
On that note,
2007 Chevrolet Express 3500 w/6.6 LMM sans exhaust + EFI Live = 6.4s 0-60 with near-death experience wheelspin and no brake boosting. Econ - ~20ish?
