    Which is exactly what previous discussions have been about. If other FCA vehicles are criticized for not having enough power, the Wrangler will certainly be trounced for it.

    Norm was very critical of four cylinder powered Wrangler’s and he was right to do it.

    When I look at missteps regarding Wrangler (2 wheel drive versions) I try to look at them in a positive light.
    They are a source of used parts to keep your Wrangler running.
    Four cylinder JL's might be the same way.

    I do not have an issue with four cylinders. I have an issue with using an underpowered four cylinder whether it is gas or diesel.

    Nice job making lemonade though. :)

    Eight speeds, no waiting... if you shift quickly enough.

    They had slant sixes in class 8 trucks.

    It's all in the tuning — and if it's a mild hybrid, that will get the engine up to speed while the turbo spools.

    Chrysler used to be known for its “no waiting” powertrains. They went away from that for a while but I can hope.

    The 8 speed is the key to the puzzle for sure.

    And a wide-ratio manual option.

    With the second generation ZF 8HP there is a second gear set that is available.
    The new one is also used by Alfa Romeo Giulia and Stelvio.

    1 2 3 4 5 6 7 8 R
    4.714 3.143 2.106 1.667 1.285 1.000 0.839 0.667 3.300
    5.000 3.200 2.143 1.720 1.314 1.000 0.822 0.640 3.456

    A 4000 lb Wrangler with a 200-250 HP engine will offer the same acceleration as a 2000 lb car with a 100-125 HP engine. That's honestly pretty decent.

    The problem is historically Chrysler has saddled their larger 4 cylinder vehicles with trash transmissions and less than optimal gearing. A nice responsive transmission with low parasitic loss makes a huge difference on smaller engines.

    Well, it couldn't be any slower than the 4cyl I had in my TJ (120HP IIRC?), but then my TJ was much lighter too (around 3000lbs?). So I'm cautiously optimistic about the new 4cyl for Wrangler. I'd still probably opt for the larger 6 but you never know.

    There is much more to the equation than weight. Aerodynamics of most 2000lb cars are far superior to those of the box on wheels Wrangler, let alone the increase in rolling resistance and parasitic drivetrain loss.

    Agree that a modern transmission such as the ZF 8spd will make a huge difference.

    As an owner of multiple 4cyl Wranglers, I will say that the level of performance and acceleration of those models would not be acceptable in today's market.

    And no 2,000 lb car has anything resembling 32" tires.

    It takes a lot more torque to turn 32" tires. Let alone the 33" tires that reportedly will appear on JL.

    Asking for a friend... Could the 8 speed be tuned so it uses 2-8 under normal driving then use the low first gear when in low range on the transfer case?

    The 2.0 T Hurricane should be good in the Wrangler with the 8-speed.

    It will not behave like a Pentastar 3.6

    It will not behave like an EcoDiesel 3.0

    But it should be adequate. The selling point will be fuel-economy and not much more.

    Technically yes, it could start in 2nd gear and even start in 1st vhen needed, for example starting uphill.
    It is what is done in Jeep Renegade/ Compass Trailhawk with 9 speed automatic, in normal conditions starts in 2nd gear.

    That's a shame, because a lot of guys were hoping this would be like the Mustang turbo-4, where you can simply load a tune to the car and outrun the V8 models. A "tuner Jeep", if you will. Would have been a load of fun and a really popular option. But it's starting to sound like that's not the case. :( This is a fuel economy sales item only.

    Just know that tunes going that deep are getting harder and harder to crack. It will happen but not out of the gate.

    The auto magazines would absolutely destroy Chrysler for bringing out a vehicle that “underpowered”.

    JL is a brick with massive, heavy tires.

    I believe the 8 speed is already tuned that way when using “eco mode”.

    Many forget that the 2.0 has BSG system, it is a mild hybrid.

    This is from Continental, but almost all system from different suppliers work the same way.



    The electric motor allows powertrain engineers to have a wider election of turbochargers.
    Why? Because the electric motor allows to have additional torque (and power) at low rpm (an electric motor has maximum torque at 0 rpm).

    To add also that newer turbochargers with ball bearing have a lower response delay.
