Living in a state that has speed limits up to 85 MPH EPA estimates are useless. If you are not driving at least 90-95 MPH , you will get ran off the road. Everyone does at least 10 over. They need to test them like they are used, at true highway speeds.

I think exactly one road in the country has a speed limit that high.

Let’s bring this thread back with some other test data. TFL did their test with the 2.7 turbo 4x4. Not only did the truck get 24.2 MPG @70 mph, but the DIC was nearly spot on. These were the numbers I was hoping for to make the 2.7 a sensible option. The Car & Driver thing was not making me feel to positive about the engine.

 

The thinner air in Colorado gave the Turbo engine some advantage over the Ram, but that Rebel did terrible by anyone’s measure. Complete embarrassment. 16.8 :nono:!!!

I think that the four-banger is more suitable for shorter trips, city driving and even more real world-ish various speeds.

And, I have to find the highway in North America where I could drive 75mph continuously.

The four-banger will find it's place. Owners who don't need bragging rights but enjoy having a big car to get the kids to soccer, the groceries on the way back and pick up the new couch from IKEA on the weekend.

 

so long

I've been waiting on the 2.7L to finally get to dealers, and am finally going to go drive one tonight. If all pans out, I will probably be ordering a loaded RST double cab with the 2.7 in a few hours.

 

I may be odd, but I hate the sound of a V8 or V6, and I am tired of waiting on the Duramax. I'm upgrading from my tuned 2015 Colorado 2.5/6MT which does a great job towing my boat and other toys, so I have no worries about the 2.7 having enough power for my needs, particularly with the diesel-like torque curve. Fuel economy has not been part of the decision in any case (my Colorado rarely makes it out of the mid teens as it is), but I was a bit shocked to see their test results - until I saw the speeds they were testing it at.

Tfl did another test and mpg came up 1 for the rebel still not great. But also factor in height weight , v8 and gearing of rebel , altitude for na engine and its easy to see why the Chevy won. still 24 mpg is impressive. Now let’s see rebel vs trail boss at same time tested

At least GM is giving more engine options. If I was looking for a reg cab truck and my choice was a V-6 with split fire or a turbo 4, I'm going 4. Then I would be looking for a tune.

For me it came down to not wanting to wait any longer. Particularly given the delay in certification of the Diesel due to the Government shutdown, God knows how long it will be.

Wonder how much of an up charge the diesel and 10 speed will be.

Will be interesting to see the diesel numbers. My stepdad has a ram eco diesel and I’m always blown away at his mpg numbers. The other side of that is that the eco-diesels are a coin toss on whether you get a good one.

I drove it last night (and based by how hard it’s been to find one, pretty sure I’m one of the first non-media with some seat time). It had 226 miles on it and was averaging 23.6 according to the DIC. 

 

It’ll move with authority, and it definitely has no problem loading about and riding a wave of boost and torque without seeming like it is working. Definitely will be fine for towing my ~4,000-5,000lb toys without issue. 

 

It definitely sounds like a big bore 4 cylinder, which I can see some people being turned off by. It sounds mechanical and the turbo is audible - but does not rumble at all (my beef with a V8). To be honest, the whole truck seemed louder than my 2015 Colorado, but I suppose I’m being nit picky. 

 

I think ill I’ll be dusting off the checkbook on Saturday and joining the Silverado family with one. Yay to 8 week order waits ?

I thought I read that the turbo 4 can also drop 2 cylinders but that may not be from an official source so take with a grain of salt.

I currently drive a car with a 2.4L NA I4 and I love the exhaust note, though my valves are a bit noisy. 

The small engine in my wife's Corolla is not more fuel efficient when I drive it because I'm impatient with the shitty 4AT and the lack of torque compared to my car and end up flooring it a lot.

Yeah, the 2.7 has AFM. 

 

Seems to tow like a champ, even at it’s limit. But it was certainly guzzling the gas.

I was really glad to see this today, and to see how well it did. 

 

I am hoping to get my order number tomorrow so the ball will be rolling. I signed my lease for the summer at the boat yard as well today - so it looks like I’m going to have a couple more tows with the Colorado under my belt this year since the Silverado won’t be here until after the start of the season. I am really curious to see how it does in comparison to my Colorado (which is an admirable champ even though my tow weight is slightly higher than its rating).

      You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.

      It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is.

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.
