Jeep’s new inline 6

[Billabob]

Looks like Jeep just dropped a new Inline 6. A liter less and 400 horsepower more than us. Any thoughts?

My first thought is a Twin turbo set up on a 4.0 would be awesome! It kinda bums me out that it's going to replace the hemi. The thought of a turbo let alone 2 on a DD scares me. They don't seem to have the reliability needed for a DD from what I have seen of factory turbos. But a straight six in a jeep is always cool.

great on paper

 

it´s been currently made in saltillo? a few hours from where i live

Meh. Its just Peugeot pushing its euro agenda in the US.

Is there supposed to be an engine underneath all that plumbing and hardware?

They have to in order to meet the EPA guidelines for fuel economy.

Has the EPA really gotten that bad? Ugh.

Not to get political, I'm a Canadian so your politics are your politics, but the previous admin rolled things back a bunch to support certain industries and the consumer as a whole.  The new admin then brought back in the targets from the admin before the previous one, plus added an adjustment to them for the 4 "lost years."

 

This means that FCA, Ford, and GM, who build a lot of pickups and SUVs that get less than stellar fuel economy, and now absolutely scrambling to come up with ways to meet the fleet average requirement set by the EPA.  GM will pump out econobox cars and some electric vehicles, Ford is likely going to hit it out of the park with their electric F-150 sales along with a fleet of econobox cars/the Mach-E, and FCA...  Well, FCA is going to do what they can to improve their existing product line, because they aren't in a great place.  I do have to give it to FCA for still offering Hellcats and other neat things to the masses, but government regulation is ultimately going to put an end to that.  Their only super high mileage weapon that is selling is the Wrangler 4xE, which is honestly a terrible product that takes advantage of the poor wording of the legislation, but they're not going to make or sell enough of them to fix their problem.

 

I embrace change.  My next MJ build will be electric.  But that's a ways out, I need enough market uptake to be able to buy the components for cheap enough.  The good news is I work super slow so my current build won't be done anytime soon.

An electric comanche would be stellar, but dang that would require a ton of work. Ideally, the under bed space would be ideal, but that X frame box construction would pose a pretty significant problem.

I do like that ford is offering their electric motor from the F150 lightning as a crate motor.

The major hurdle here is the missing letter!

Here's to 'maNche-9000

Nice that they're offering it, but I don't know if it's a good enough deal to go that route.

 

Honestly the electric vehicles seem easy, as long as you're willing to accept marginal results.  You could do a simple DC motor conversion and use Leaf or Bolt batteries and be into it for only $5000~ max.  A Matzilla controller will do that and you're pretty reliable with not much else save an electric vacuum and P/S pump.  Put the battery in the box and you don't even have to modify it, totally hack but it gets you going.

 

If you want something better you're really stuck as far as what way to go. Tesla drive units are made for a car, period.  I don't know what they're planning to do in the truck, or if it actually will ever hit the market, but if they're using the same basic drive units then it's worthless.  Everything else is far enough behind in power that you might as well just buy an actual race/performance motor, like a Hyper-9 or whatever, and buy or build the adapter.  That's all assuming you want a 4wd truck, otherwise just use a Tesla rear drive unit and the horrible Tesla IRS, it will work.

 

My tentative "plan" if I was to go electric in an MJ would be a battery box where the gas tank is, and another on the other side, and one where the spare tire goes.  There's enough cubes there to get you maybe 150 miles of range, given how bad aero and rolling resistance would be.  If you want more it's going to get a lot harder.

 

But like I said, that's a long time down the road.  So I'm not thinking about it too much because everything will change in the next few years.

First, depends on how the two turbos are used. On some applications, they are to keep the compression ratio the same, through out the rpm range. That is mainly for emissions. Also, fuel economy with power is also doable. Its good to see some company(ies) still investing in gas motors.

I envision an electric MJ would have the motor in the trans tunnel, bolted direct to the transfer case, with the battery packs under the hood. But of course that would require an adequate motor for single-speed operation. The Magna electric drive axle also looks like a pretty good option, and I’m sure more will become available in the next bunch of years. 
I suppose if you really wanted the Tesla drive unit you could always stick it in the middle and drive an axle off each end of it, so long as full-time AWD is alright.

Direct mounting the motor to the tcase is difficult for use in a truck, as a truck.  Most of the motors don't have a great efficiency curve for it and want to run at too high of RPM, at least of the AC motors.  DC tend to prefer the lower RPMs, but won't have the jam to be useful in a truck without gear reduction, and then don't make enough top end to run highway speeds if you run the tcase in low range.  Guys do it, but the results are meh.  Plus DC is only good if you're really trying to do a cheap build, as you can't use it for regen/engine braking.  Keeping the transmission, even if you only ever use 2 or 3 gears, seems to just work out a lot better with most of the motors on the market.  A smaller/lighter 3spd tranny from an older jeep/truck might be ideal, but I didn't do any numbers on it.  You're kinda stuck in you don't want to have a clutch, but you do sort of need one to shift because the rotating mass of the motor is really hard on synchros without one.  It's been done both ways, but nothing seems ideal.

 

Finding high enough gears for your axles is what limits turning the Tesla drive units sideways and using them that way.  If it's a crawler it works fine, but way too low for street use.  Lots of smaller buggies were built using FWD car engine/transaxle sets configured that way.   You can pull the Tesla drive units apart and use the motors/inverter without the rest of it, but I've not seen any that were done to a standard that was capable of being suitable for daily use.  Honestly if the Tesla drive units had multiple gears they probably would be a bunch more efficient, and I'm curious what they will do in the "Cybertruck" POS they're going to maybe start delivering in 2130.

 

Really it's a case of just waiting to see what government subsidies develop and using whatever works and becomes cheap.

dirty comanche, you seem pretty knowledgable on the ev conversion subject. do you have a good link for leaf or bolt batteires?

Nothing currently I don't think, because I haven't been looking.  But www.diyelectriccar.com often has stuff come up for sale in their classifieds.  EVWest sometimes will sell things like that too.  And you can watch for them with the wreckers using whatever for that (carpart.com I think is a big one).
