I find it interesting that the 5.3 is apparently way faster but the 6.2 got slower... GM still hasn't gotten their sh!t together.

I suspect the ten speed might slow it down a bit in certain circumstances. Certainly in theory it should smoke the K2. But Car & Driver tested a 19 HC 6.2 and it had the exact 0-60 (5.4) that the 2014 did with a 6 speed. Motorweek got a Denali to do it in 5.7. Both of these trucks had the 3.23 though. I believe some of the earlier tests of the K2 had a 3.42 read end. At any rate it’s still faster than a pickup needs to be. :cool:

 

Even the 2.7 is said to do 60 in 7 seconds. Not long ago that would have been the fastest truck since the Syclone or SRT Ram. Think we’re all getting spoiled.

I test drove a 2018 6.2 and the 2019 5.3 back to back and then swapped back again. The engines felt pretty much identical.

I know my 17 took 7-10,000 kms to feel like it was 6.2. Stepped on it one morning, couldn't stop grinning the rest of the day.

Glad you shared that. Hate to think they shaved 450 pounds, went to a 10 spd and got slower. That being said, I would have thought losing that much weight would have had more of an improvement with acceleration.

 

Anyone know the top speed of the 19's? Looks like it did the 1/4mile .1 quicker at 100mph. 100 the limit? Looks like the ecoboost goes 5.1 and 13.7. Unfortunate gm didn't update the engine a little bit...

Well, for what it’s worth, that’s the Raptor’s 3.5 in those C&D figures, not the standard 3.5 that 99% of F150s would have. You can only get it if you spend 70k on the Limited (or a Raptor). I think the 6.2 is a bit more reasonable as an LTZ 6.2 could be had for 20k less than the Limited. Plus, I think if the HC they tested had NHT, the margin would be even smaller.

Completely different engine tech, but its embarrassing that an engine with1.2 litres less displacement, isn't far behind. Guess gm should be thankful ford didn't make a new gen 6.2...

One of the most common comments I've heard about the 19's here is better throttle response. I'm waiting to see REAL empirical data on these trucks compared to the others brands and not SOTP or TFL mash ups.  There's been one legitimate tests with 19' crew 4x4's (professional drivers, data collecting) and the 6.2 beat an Ecoboost and destroyed a 5.7/3.92 Ram. In fact, I won't be surprised if the Ram 5.7 is more comparable to the 5.3.

Well, I can tell you now. Car and driver always has the fastest times for gm trucks... anywhere... Unless you count some guy driving down a hill with his g-tech; claiming 4.6 seconds 60mph. Motortrend always has the slowest times. I think everyone else just copies and pastes.

I’d say it is, much to FCA’s embarrassment. It’s 0-60 is only 2/10ths of a second faster than a 5.3 TrailBoss. And that’s with it’s 3.92 & 40 more horses against a lifted truck probably on Duratracs.

 

Why every magazine has given such slack to the Ram for its abysmal fuel economy and performance is baffling to me. That interior must really be great!

FWIW, I drove a 19 5.3 and right after a 19 6.2. The 5.3 had plenty of power but what stood out to me was how responsive the 6.2 was to throttle input. It didn’t matter how fast you were going - when you needed power in the 6.2, the transmission responded with the right downshifts and the right amount of power. Very linear. When I drove the 5.3 I noticed it was hesitant to kick down and when it did, it was too much all at once. Like 2 gears down and 100 hp in half a second. Day to day driving for most folks it is probably fine but I’m a bit of a tranny snob and I preferred the 6.2. My .02.

I’ll add to the above. HP and torque-wise, the 5.3 is more than adequate. Put that 10-speed tranny in the 5.3 and tuned like it is in the 6.2 would be a sweet combo.

Having test driven a 5.7 Hemi in the past week, I don't think it's much, if any quicker than the 2019 5.3 DFM engines. I'll admit I was impressed at first, having only driven my 18 5.3  but then I drove a 19 5.3 and all of a sudden that hemi wasn't so impressive anymore.

I wouldn’t be too sure. I read recently the collector car market is turning Asian. Maybe Ford had the right idea, turbo engines. The fast and furious crowd loves tuner turbo engines. Mustang and Camaro have turbo 4s now. Makes sense an Asian cars lover needs a full sized pick up they go turbo engine.

I'm a fan of the turbo Camaro, If this 2.7 makes it into them in the next couple of years I may buy one if the 1LE package is still offered.

They probably use the touch screen for, uh, special types of "entertainment"  :D :uhoh: :pimp:

      2027 GMC Sierra: Official Discussion

      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

      By davester · Posted

      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.
