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

Wow that's a pretty insane drop. Almost makes you wonder if it would be worth it to have road tires for driving around and swap to AT when you are going to do trails and stuff.

Off Highway Vehicle enthusiast used to do just that. Some still do.

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.

I don't know much about gasoline powered generators but this info from Copilot AI FYI:

In Extended Range Electric Vehicles (EREVs), the internal combustion engine (ICE) primarily acts as a generator to recharge the battery rather than directly powering the vehicle. This setup subjects the ICE to different types of stress compared to traditional vehicles:

1. Load Variability: The engine operates at varying loads depending on the battery's state of charge and the vehicle's power demands. This can lead to fluctuating stress levels on the engine components.

2. Efficiency Focus: Since the engine's main role is to generate electricity, it typically runs at a more consistent and efficient range, reducing wear and tear associated with stop-and-go driving.

3. Temperature Management: The engine may experience different thermal stresses due to its intermittent operation and the need to maintain optimal temperatures for efficient electricity generation.

Overall, the ICE in an EREV tends to have a more stable and efficient operating environment, which can potentially lead to longer engine life and reduced maintenance compared to traditional ICEs.
