2020 SIlverado HD 6.6 Gas Review and Off Road Traction Test

We take the 2020 Chevy 2500 with the 6.6 V8 gas engine to the foothills for a brief review. Then we compared it to a 2017 GMC to see how the exteriors are different as far as bed size, cab size, and overall length.

Very thorough comparison. I own a 2020 and there were several moments where I was like "no way, i did not know that ". Well done.

Glad I was able to help! Thanks for watching!

Really nice to see a tried and true V8.This is a go to truck for most of the Class 1 Railroads.These trucks have at least 1000 lbs of equipment from day one.They get used 24/7.Impressive Trucks.Very reliable.

[@EngineAdventures]

I haven't heard much about this engine good or bad. I generally prefer gas engines because of the not tried and not true emissions systems on modern diesels. Thanks for sharing your experience with it!

[@damitbobby6677]

Those front ends are really growing on me

[@EngineAdventures]

I didn't like the first pictures of the truck when it was released, but when I see them in person they certainly aren't as bad as they appear in photos. The hood is high, which makes maneuvering in tight spaces a pain. After driving the truck for a week you start to get a feel for where the front end actually is, but it's not as easy as the Ram.

[@TomJonesGearGuy]

I just got one and when the pics of it first started coming out many people had their questions about the front but I liked it and I have been surprised how many people have come up to me to say how good looking the truck is. One thing not mentioned and it is what I hate about this truck, storage in the front of the cab. It has two glove boxes the bottom is good but the top one pretty much a waste it is so shallow should have just left it out. No storage in the jump set in the front, you have to upgrade to get it. So I tend to run them till they are dead. Traded in a 2001 2500HD with 315,000 miles on it. It was still running but trans and transfer were both leaking bad and just could not put the money into it anymore. What was nice was you had the little cubby space behind the rearview mirror, it had an ashtray that worked great for change, business cards and other little stuff and you had storage at the middle seat front. Losing all that hurt. Other than that I like it a lot, a solid truck.

[@MB.1111]

These things really have an industrial look to them...tough machines just like a truck should be. I'd definitely go for the duramax though.

[@EngineAdventures]

I wish they offered the gas with the 10 speed auto. When Ram switched from a 6 speed to an 8 speed in the 6.4 Hemi it made a huge difference. That said, how can you pass on a diesel with 910 lb-ft of torque?

[@jredd801]

I love this color scheme..

[@sheehy933]

Did you mention what tires come on it ? Seems like some better tires would improve initial grip to get it going.

[@EngineAdventures]

They were Goodyear Wrangler TrailRunner ATs. My testing is designed to test how the vehicles transfer power side to side and back to front, tires are irrelevant for what I'm going for. Yes better tires would make a difference in most of my tests, but they wont overcome a bad traction system. Overall the G80 does quite well, you just have to know how to work it. Chevy has one of the weakest brake limited slips on the market, which is good in a lot of scenarios but not good in others. Thanks for watching!

[@rook13pdx]

I'm wondering how long until the aftermarket gives us a built-to-fit electric fan kit. Seems like it would clear up A LOT of space under there, give a few extra HP, etc...

[@EngineAdventures]

I'm not sure what the current state of electric fans are, but in the past an engine driven fan provided more cooling more efficiently than electric. Electric fans require transferring engine power to the alternator, which charges the battery, which then runs an electric motor which turns the fan. Engine driven fans are direct to the fan. This is especially good for heavy haulers who will be needing constant cooling rather than intermittent.

[@speterbilt]

I love this truck. Dont need all that electronic crap. I'd put air lockers in with a cheap slide in camper.

[@EngineAdventures]

I'm conflicted on whether or not I like electronics. On one hand they do things that no purely mechanical system can, on the other hand how reliable and consistent are they? Thanks for watching and commenting!

[@dantimber]

Regarding the "lowered GVWR, 10,000 pound" option does that mean the rear leaf swings are actually lower capacity or is this just a legal designation? Would that offer a smoother ride for those who don't need higher load capacity?

[@EngineAdventures]

Great question! I don't know the answer.

Everything remains the same other than on paper what the truck can weigh, towing capacity remains the same

The G80 rear locker is an option on both 2wd and 4wd GM trucks. The system that brakes the spinning wheels is standard on all the trucks.

[@zachtremblay4618]

Whenever I see anyone pushing those mirrors in and out, they look like they’re going to fall right apart. Also, I can’t believe they didn’t put storage in the center armrest. That’s pretty ridiculous. Good looking truck though.

[@EngineAdventures]

This is a low end model, so that's why no center armrest storage, and the mirrors are actually quite sturdy and I had no issues with them fluttering at freeway speeds.

[@kenmic3661]

2021's center console actually opens on the custom

[@EngineAdventures]

Does it have storage top and bottom?

[@HTSS8]

Why is the center console not opening in this one? Just saw another video, it did, same Custom trim.

I think someone commented that the 2021 has the center console that opens.

[@HTSS8]

@@EngineAdventures Hmmm, seems pretty dumb, to then have manufacturing of 2 things exactly the same just one small difference and too keep up with tooling and logistics. Should have just did the first make.

[@EngineAdventures]

@@HTSS8 I agree, and I think they noticed that people want the extra space, so they made it standard. They make so many trucks that tooling costs are quickly recovered for these small savings. Otherwise there would only be 3 trim levels like there were on the past.

They were fine for me on this truck, I've had others that weren't up to par on other vehicles.

[@ncurc9766]

Would you prefer this or a 6.4 ram w/8 speed?

[@EngineAdventures]

Tough question, I did find the 6 speed lacking at some points, the 8 speed did much better with the two extra gears, and it seemed to always be in the right gear. I trust the GM 6 speed for longevity more than I do the Ram's 8 speed. As far as the engines go it's hard to say between the two, the Chevy might be a little better, but the Ford 7.3 was the best of the 3. I didn't like the 10 speed as much as the 8 speed though.

[@jc7435]

7.3 10spd w/ 4.30s!

[@EngineAdventures]

I love the 7.3, it's my favorite has engine. Ram's 8 speed shifts and just seems better than the Ford 10 speed though. Somehow GM makes the 10 speed integrate much better than Ford does.

[@clarencejohnson3197]

The GM 6speed transmission can handle up to a max horsepower of 700.

[@asherdie]

Auxiliary battery is optional

[@EngineAdventures]

I didn't know you could get two batteries in the gas versions. The diesels come with two.

[@slimtny]

Its funny on the diesel resale thing. The resale price difference is exactly the 10k or so you paid for the diesel over the gasser. So you're not gaining a higher value really.

[@EngineAdventures]

There are certainly tradeoffs for both!

[@vergilwarren2403]

where is the on road review

I had 3 trucks that week as I was leading a trailer towing safety and driving course. I only had a short time to film each truck and didn't get as much done on them as I would have liked.

[@TrueMagisterium]

Fake hood scoop on the gas engines? My diesel hood scoop is active.

[@EngineAdventures]

Yeah on the diesels it's functional, but not on the gas engines.

[@TrueMagisterium]

@@EngineAdventures I suppose the diesel wars had them hunting for extra power, but they could have easily incorporated it into the gas engine as well. It’s a shame they didn’t.

[@EngineAdventures]

I agree!

[@scz718645]

I think you meant EGR on the diesel

[@EngineAdventures]

EGR (exhaust gas recirculation) is also on many new gasoline engines to help reduce emissions. SCR (selective catalytic reduction) is the system that uses diesel exhaust fluid to reduce emissions. There is also the diesel particulate filter that catches soot, then burns it off in the regeneration process. The diesel exhaust system is complex and expensive.

[@scz718645]

@@EngineAdventures Iv never heard of DPF system called SGR.

[@EngineAdventures]

@@scz718645 they are separate systems, I might have to watch the video again to see what I said for sure, but I think I meant the DPF because a truck at my work was having problems with the DPF and it is only 3 years old with 30k miles.

[@EGGINFOOLS]

How childish

[@n.l.7308]

It's not worth it. With that mpg waste of money. Just buy the diesel.

[@EngineAdventures]

I thought so too, but when I ran the math it would take over 450k miles with the gas engine averaging 15 mpg and the diesel averaging 19 mpg and using mid grade gas and highway diesel based on current average prices in the US. There are definitely situations where a diesel makes more sense, but for most people it doesn't. If you add in resale values, yes diesel will get you more money back than the gas but not the original up front cost, and maintenance is typically more on a diesel. It's not as straight forward as it seems, as there are cases for both. Also, most people don't buy the most practical vehicle, they buy the one they want. It's hard to turn down 900+ ft-lbs of torque.

[@TomJonesGearGuy]

You do get the torque from the diesel but I look at my truck as 36 gal gas backup too. My back up cookstove can burn unleaded and my generator burns unleaded. When you go almost half the year in hurricane season you plan for the worst. Plus I have always run gas, can fix gas and no diesel stuff to deal with.

[@EGGINFOOLS]

People that say that never do the math

[@Cla55clown]

$10K premium for the diesel. Then you have the more expensive maintenance, the DEF, and much more expensive repairs when things go bad. Around here, diesel fuel carries a $1 premium/gal over regular unleaded. Add it all up and that's a HUGE price difference over the life of the truck. For what, a little better gas mileage and tow the trailer up the hill a couple minutes faster at lower revs?

[@RobertoHernandez-cd9bs]

Uh diesel is worse mpg !

[@chadhaire1711]

These MPG figures are bogus. Best you will ever see at 75 MPH in the 6.6 gas is 14, best on the 6.6 diesel is 17/18. You must be driving downhill.

[@EngineAdventures]

We drove to Vegas and back in a 2017 crew cab long bed GMC 3500 with the 6.6 diesel and averaged 17 mpg for the trip. Speed limits are 80 for most of the freeway portions and we had the cruise set to at least 83 if not more for most of the trip. That was round trip MPG and about 800 total miles. Only stopped for fuel once. We've seen just over 20 mpg on short trips at lower speeds, but it's hard to get exact mileage on those shorter ones because there is limited data and we typically don't top off before and after a short trip.

[@fit4ya1975]

I bought the Denali 2500 Duramax last week, took a 220 mile trip and best mpg was 23.2 on freeway at 77mph. Over all avg with some stop and go for that trip was 19.4. Not bad for a brand new truck.
