Gas mileage

[irishwake63]

I get great mileage in my 22 just horrible when towing my last 3 trucks generally got about 11 mpg when towing the same trailer (camper) and this one gets about 7-8

The real reason for the Hurricane isn't CAFE like some think, joining Stellantis with their large portfolio of more efficient small engines fixed that. FIAT-Chrysler no longer needed to buy carbon credits from Tesla after Stellantis merger/purchase.

I'm pretty sure that's not how it works. There are different CAFE standards for different categories of vehicles. Merging with FIAT may have helped them meet standards for small passenger cars, but it did not help them achieve the 39 MPG average required for light duty trucks.

Just because they are not buying carbon credits does not mean they are not paying EPA fines. According to this story, only 2/3rds of Stellantis budget what went to excess emissions costs were covered through Tesla carbon credits. CAFE fines are expected to cost Stellantis $3 billion in the next 8 years or so.

The fines Stellantis paid are due to previous years overages, I don't remember how many model years, but it could have been prior to the merger.

But good point on CAFE, though when discussing the reason for the Hurricane with the head engineer, he stated the big reason was half the emission of the Hemi, which is the reason why GM had to redesign their 5.3L and 6.2L going forward, not CAFE specific but Emissions.

When you consider the Hurricane only gets about 1mpg overall improvement, while have 50% less emissions, you can see what they were going for with this motor. Clearly Emissions over CAFE.

I'm actually surprised the Hemi lasted as long as it did. I think when they first started selling it they had difficulty meeting emission standards so had to add a second spark plug to fire on the exhaust stroke to ignite unburnt fuel from the compression stroke.

It's a dinosaur these days for sure. I think CAFE however is based as the corporate fleet in light duty, up to 8,500 lbs, so the 1500 should be in that grouping, but honestly not sure.

I'm not sure about the exact weight but the CAFE standards are somewhat complex. The 1500 and passenger cars fall under the general category "light duty vehicles" but under that there are specific standards for "passenger cars" and separate standards for "light trucks". For light trucks there are even different standard for 2 vs 4 wheel drive. It's more complex than I care to really examine in detail, but I gathered they use the higher category (light duty vehicles) corporate average to determine compliance then if not compliant issue fines based on the lower level category standards.

Good info, I'll wade into it sometime

Just got back from my annual Christmas trip to Texas from Arizona. Averaged 17mpg. Had one tank that got 18. I'm guessing highway milage differs state to state. Texas has 85 mph speed limits on a lot of roads. You know what that means.....90 mph Then you go to California and it's 55 and 60. I can see why I used a bit more over in Texas. Still telling neighbors it gets 23.

Haven't towed with it yet, but almost two years driving now and the worst I've gotten is 16.6 (back and forth to work 5 1/2 miles each way) and the best was 22.7 (highway). Pretty satisfied compared to my prior vehicle (Tahoe) which was about 13 and 18.

Since I've had the RAM and back in a V8 truck for 3 months now, I don't even have a radio. I have 16mpg because it's fun and I love the drive. All I hear is the engine and I love it. I disable the noise cancelling in the cab because it was creating all sorts of weird noises to compensate for what it thought it should cancel out and now it's just flawless growl, and no, the cab is not filled with excess exterior noise either. Not that I notice or ever have in any (good condition) vehicle. $30 or so for a plug in to the amp and it was noticeable on the first drive.

When I wanna jam, I still do (read that again in a Forrest Gump voice). But it's so rare. I love hearing everything else. And I'm proud of my 16 MPG because that's moderate for how I feel on the roads now days... Lucky I'm not getting 3 MPG and I will also shamelessly admit that yes, that was me flexing my loud pipes as I passed your slow self

JK I'm a mostly responsible driver (on public roads) but seriously way too many crappy ones out there and now I have loud pipes so yea I'm gonna use em, suck it. Glad to be that "typical RAM owner" vs. the ones making assumptions and not paying attention to the road.

Can you tell why I bought the truck? If I could afford a TRX it would be a no brainer to me, and I'd true dual it.

22 model 1500 5.7 Limited. Computer says:
Summer highway 285x45x22, 22mpg. Winter, same tire size with studs 19mpg. In city and other driving 14-17mpg. "Higway" speedlimit mostly 50mph though. I found that 53 mph is best speed for good fuel economy.

I have resigned myself to the fact I own a petrol thirsty girl, I just let her drink what and how much she wants! Lol
