2021 JLU vs 2020 Grand Cherokee Acceleration

[Namakan]

I’m surprised by the difference in acceleration between my wife’s GC limited with 3.6 versus my 2021 JLU with 3.6 etorque. If I’m comparing things right they both have the same transmission and gear ratio. Similar curb weight and wheelbase as well. The GC feels so much quicker to 60 than the JLU. Is it just perception or am I correct?

Tires and software setting on the transmission would be different between the two vehicles.

Your Grand Cherokee has some curves and shapes that give it an advantage with aerodynamics, too. It's not a night and day difference, but it's definitely there.

There’s big differences in tire size, gearing, aerodynamics, who goes on top under the sheets, etc., etc.

Aerodynamics. Notice how most vehicles today are shaped the same and look nothing like a Wranglers boxiness? Less resistance gives better fuel economy and better acceleration. It’s partly why a Wrangler is loud and rides poorly on the highway.

I would suspect more of this due to programming, tires, and suspension. Your Wrangler isn’t made for clicking off quarter mile times.

From what I can tell the posted 0-60 times are the same for the GC and Wrangler with 3.6. Interesting.

Those numbers are interesting but not what I'm experiencing. There is no way my JLU is quicker to 60 than our GC. Thanks for the replies!

I have both and the GC feels faster. I wonder if they did the 0-60 in the eco mode and not the sport mode. There is a big difference in both. There is a noticeable difference between eco, regular, and sport. Acceleration feels the same in regular and sport but sport holds onto a gear longer (before up shift) than regular mode. Now having said the previous, I don't really know the acceleration of a stock wrangler as I've had the lift and 37's on it from the beginning ;-)

I agree with this. There is no way that the JLU (and especially my Rubicon) is anywhere near as quick as a JGC. In addition to what others mentioned, the Wrangler has a lot more unsprung weight.

I just came from a 3.6 GC to a 3.6 Rubicon. The Rubicon feels so much slower.

JL/JLU Sport is geared higher than the Rubicon so would accelerate slower.

I read this earlier, and just ran out to pick something up, I realized what the OP's mistake was.

You should have got the 2.0T, then there would be no 3.6 regrets

We’ve previously tested the Wrangler’s largely carryover 285-hp 3.6-liter V-6 and would go so far as to say that that Jeep is quick for a 4469-pound body-on-frame machine that appears to have been designed to help Richard Leakey hunt for Australopithecus remains. That one needed 6.8 seconds to get from zero to 60 mph. With the turbo four—closely related to the engine in the Alfa Romeo Giulia and Stelvio—the Wrangler is even quicker. Despite being slightly down on power compared with the six, it hits 60 in 6.5 seconds. It seems relevant to mention that the four is built in Termoli, Italy, and that Italians hate losing races.​
