After having my leveling on the truck for a little over a month the truck was getting 16 mpg before the kit now after I installed it the truck went down to 14 mpg so I said the hell with this and I removed it and now with the same driving everyday both with and with out the kit the truck went back to 16 mpg with the kit removed. I filled up at the same station during this and the same driving was almost to the tee.

 

So with the truck front up in the air level with the rear it really put more wind drag on it which is expected and screwed with the aerodynamics, so iam just wondering if anyone else saw this. Yeah it looks good leveled but not at the cost of -2 mpg at 4 bucks a gallon. Mileage was hand calc.

I can't tell you what my mileage would be without the level and 305/50/20 AT tires (and front valance removed) since I only drove the truck a few days without these items. I can say that I get 14 combined MPG on a 6.2l and I tend to drive 20 over on the highway and 10 over in the city. I do try to acceralate to cruising speeds more gently then I used to (+1 MPG). I did try 2 weeks of very gentle accelation and only going 5 over on the highway...mileage jumped to 16 combined. I decided I'd rather enjoy driving the truck then try to save gas, so I'm back down to 14 now.

 

Sadly, 14mpg is the same MPG I getting on the SL65AMG I have in my garage (it's a 604hp/738lbft, 4300lb, 6.0L biturbo V12 roadster). If the 65 wasn't black, I'd buy keep it for myself. Very polically incorrect, very fun to drive once you figure out how to drive it and still get some traction (or keep the electronic nannys at bay).

 

Pretty soon, being able to afford to drive a PU or SUV will be sort of a status symbol of sorts (I said this to my GMC saleman in October and he thought I was joking).

Do you drive mostly city or highway? I would expect that kind of dropoff on the highway (well, maybe, that still seems extreme) but in the city I wouldn't expect to see much, if any, drop off.

I've been making jokes like this since the price of gas first went up.

I saw no change that I could really quantify when I go the leveling kit. Within a week or so of getting it installed, I did switch to Centerline wheels, which were just under HALF the weight of my stock 20's...did that absorb the possible loss? Who knows...

 

I get 17-18 on the highway, which is what I got new.

 

I still get 11 in town, nothing has changed.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      Interesting pivot.

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
