TFLTruck tests 2017 Chevy 3500

The timing on those tests would have merit if there wasn't traffic, or if they went full throttle all the way. But there is traffic, and they don't go full throttle. Given that, the times don't mean much of anything. With an equal load I would expect the Duramax to be the fastest followed by the Powerstroke and then the Cummins. In the real world they're all plenty fast and powerful, though - it literally wasn't something I even considered when I evaluated the three.
