Chevy passed out a 2019 Silverado information book to journalists during this week's media drive. I'm working on scanning the entire thing and sharing it here. There's a lot of information packed into this flip book. I thought the most interesting was the engine line up and an AFM vs DFM diagram. This is the best comparison blowout diagram I've seen so far. Here's the four pages related to the engines.
Zane Merva Executive Editor, GM-Trucks.com 6/29/2018 Even with an all new dynamic fuel management system, the 2019 Silverado equipped with a 5.3L or 6.2L engine won't see any better fuel economy then their 2018 predecessor. Today Chevrolet released more information on what the 2019 Silverado will cost and what fuel economy we'll see. Here's the new chart.. 2019 CHEVROLET SILVERADO CAPABILITIES 4.3L V-6 w/AFM (6-spd.) 5.3L V-8 w/AFM (6-spd.) 2.7L I-4 Turbo w/AFM (8-spd.) 5.3L V-8 w/DFM (8-spd.) 6.2L V-8 w/DFM (10-spd.) 3.0L I-6 Turbo-Diesel (10-spd.) Horsepower 285 355 310 355 420 TBA Torque 305 383 348 383 460 TBA Max towing 8,000 11,000 7,200 11,600 12,200 TBA Max payload 2,500 2,430 2,280 2,190 2,100 TBA EPA-estimates (city/hwy/comb) N/A N/A N/A 17/23/19 16/20/17 N/A From these official figures, a 2019 Silverado with the 5.3L is rated 17 MPG City , 23 MPG Highway and 19 MPG Combined. The 2019 6.2L is rated at 16 MPG City, 20 MPG Highway, and 17 MPG Combined. Chevy does not specificy if these numbers are for 2 or 4 wheel drive, so we can only guess. If it's 2WD, then the 5.3L gains 1MPG in the City but stays flat in the Highway and Combined ratings compared to 2018 figures. The 6.2L also gains 1MPG in the city but loses 1MPG in the Highway rating. The Combined rating stays flat. So, where is the big benefit to DFM? Is GM's new fancy technology going to wow in real world driving or just with fancy words? We'll find out soon when we take delivery of our 2019 Long Term Silverado LTZ in a few weeks. See Also:
