I bought the 2018 4x4 Silverado crew cab with eassist. I have mixed feelings. I’m not really sure how the eassist helps with power or torque. The auto stop/start feature is nice if you live in an area where you’re waiting at traffic lights frequently. Kinda sucks if you live where you’re not in traffic much. Seems like it should have at least 3 seconds or more before it shuts off? It’s ridiculous to shut off when you’re just stopping at a four way stop etc. I think the auto start/stop on eassist is better than other brands that use the starter. It just instantly whirs back on.
I do believe eassist helps mileage. I currently got 21.5 mpg on a road trip with a couple hundred pounds of stuff in the bed and I actually checked it at the pump, not relying on the computer which always says you’re getting better mpg than actual. I did notice on a trip when towing my small camp trailer I was getting 13 mpg. I towed the same trailer on the same route in my 2015 Yukon and it only got 9 mpg. Yukon has the same gen 5.3. The option to jumpstart yourself is pretty cool. Except my trailer light was left on and totally drained my battery, if your battery is completely dead you can’t access the info screen to activate the jumpstart feature. I do notice that the 8speed transmission is very clunky, bumpy and shifts rough, but I’ve read that it’s like that in a lot of the trucks without the eassist. Another thing is that I don’t notice it as much when truck goes to v4 mode...I don’t get the lagging sound and lugging like in my Yukon and the regular Silverado I test drove. GM says the eassist helps the truck to stay in V4 mode longer. Only time will tell...not sure what it’s going to be like when the batteries or other components need service or replacing? Probably expensive??
Check out the MPG ratings...kinda strange that it gets less MPG than the standard 5.3 with the 6 speed...but it gets better than the standard 5.3 with the 8 speed.
If I could go back I probably wouldn’t have got the eassist.
Not sure if it’s worth it since I’m not seeing a significant fuel mileage increase. I do have to say that it tows amazing and hwy driving is amazing as well. Driving around town...not so nice. Clunky, surging, shifting hard and rough. Engine shutting off when stopped for a second.
