2016 Duramax vs 2002 Duramax Mashup

To determine fuel used by clicking off waiting 30 seconds then squeeze/click is a joke.

Thanks for posting!

Yep I thought the results were interesting.

Cool comparison but would have rather seen them run at 65mph with both in 5th.

They're wrong about why the '16 got worse mileage. Has nothing to do with the higher output OR weight since combined weights were identical. Its ALL about the emissions components... Delete the '16 to let it breathe and it would have probably gotten close to 12mpg. They also failed to say (if they even knew...) if the '16 did a regen cycle in that 100mi loop which would have significantly changed the numbers.

FWIW the MPG readout on the '16 is about as far off on the high side as my 2012.

Makes me miss my 02 dmax Silverado. New trucks are soooo quiet though.
