4-Cylinder Harvester EREV engine confirmed by CEO Scott! + 0-60mph, range, payload, towing specs discussions

[Ajangel]

This had great info, now we can start filling up some of the blanks.
I wonder what 4 cylinder engine they'll use.

Yeah, wondering the same here.

Most 4's are inline and are fairly tall. The proposed space seems short and wide.

A boxer seems like the logical choice. Unless the 4's in question can lay on their side. But that would seem to require a rework of the pan, oil pickup, etc.

Personally, I would love to see a modern boxer used here. The 718 Boxster's engine would be a powerful and efficient option.

It would also ease my mind about the long-term durability of the EREV's ICE. ?

Thanks for the updates @timmyhil ?

Yes! Thanks!

Holy shit. At 53 minutes he says the range extender and fuel tank are upgradeable - bigger tank, more power on the range extender (more range or power).

Can’t tell if he’s talking about aftermarket upgrades, or Scout offering different options for harvester engine/tank down the road but either way !!!

That is interesting...

If buyers can decide EV range and gas range that really will be something.

They may have to remove the turbo to simplify things, specially the cooling aspect of it.

Just out of Warranty I don't want to be dealing with a replacement turbocharger expense.
Honda is using an electric supercharger on some compact engines with great success.

Well hopefully they have these variants produced and (insert favorite social media car reviewer) are able to drive, test, and let us know what we’re ordering before we commit to picking our colors. I’m going to hit snooze and catch a few more years of sleep and wake up when this is sorted out.

Candy Apple Green would be nice, but unlikely. Looks good on the new Mini Coopers.
We do want to see our color choice on the vehicle before we order.

Ok… I’ll admit it - I’m confused and this is kind of off track: Is the Harvester 4 cylinder engine intended to (only) trickle charge the battery (similar to the BMW i3, i.e., an onboard generator) or will it be connected to the drive train and become the primary energy source once the battery has been diminished?

Not connected to the drive train via transmission, but supposedly enough power to keep you going while towing - not a trickle charge but a full generator.

Thought that was the design but needed to check - Thanks for clearing that up (time for another coffee)!!!

I'm hoping they can keep the engine naturally aspirated. And not rely on the high horsepower part of the power curve. As the engine will last a lot longer (and run cooler) if they do. ?

Well shoot! While 0-60 times are often dismissed as not important, it is a measuring stick to comparing vehicles. Scout said sub 3 second, right? Now it’s 3.5 and a second more in Harvester? Larger Rivian R1 and smaller R2 are better and already out or coming next year so even more disappointing to wait two more years for something that will be even less stellar. So what do we have left to hope for? That it’ll look like and have the quality of these prototypes? If not, then Rivian will be the Acura to this Honda, Xfinity to this Nissan, you get it.

Seriously bummed.

As the owner of a 4 sec 0-60 car, I understand how seldom you can truly utilize this level of power and quickness. Not to mention the suspension and brakes needed to safely control all of it. If Scout can produce a real world 5.5 sec 0-60 vehicle I will be MORE than satisfied. That's absolutely plenty of speed for an offroad oriented vehicle. Give me max range over more speed any day. The larger fuel tank option could be yet another game changer for Scout. So far these guys are checking all my boxes, just hope the production version delivers!

Keep in mind that non-LFP battery BEVs are best operated between 80-20% charge. The occasional 100% charge for roadtrips and the like when you really need the extra range is of course possible. But this means that for the Harvester version you’re really looking at more like a 90mi daily usable range. Not good.

If its cheaper chemistry and less dense, then it is likely LFP for the Harvester. It would be illogical for them to go with NMC for the Harvester since its a low range of 150 miles, people will want/need to charge it to 100% more often. Very, very unlikely its going to be NMC.
