The awful sound in the video is just whatever electric drive train and gearbox Scout thew together for the prototype just to be able to move it around on it's own without having to push it everywhere for events. I honestly wouldn't be surprised if they had a small golf cart motor or something similar in it. It also definitely didn't actually have a harvester engine in that one even though it was the "Harvester" Traveler. I'm sure they have millions into the couple of prototypes they currently have (Scott even made a comment to Jay that it's probably the most expensive vehicle Jay has ever driven. And knowing what Jay's car collection is like and some of the vehicles he's driven Scout must have some serious money into those) so the goal is to keep costs down on them as much as possible. Eventually once the factory starts going online and they get close to being able to start production they will make a couple pre-production models with the actual drive train and E-beam axles in them. If those versions still sound like this one then I would worry, but for the one Jay drove around at 15mph on a tarmac, I wouldn't pay any attention to what it sounded like or even how it appeared to drive or handle. That's why Jay had to comment about a dozen times that it's just a prototype and not at all what the final product will sound like. The Harvester version should be as quiet as the full electric version and as quiet as any other electric vehicle on the market these days. The only real question is going to be what that little 4 cylinder is going to sound like when it kicks on and runs. Like Scott said in the video with it being so small and tucked away in the back the driver shouldn't even notice it running. However what he didn't mention was how it would sound to the rear seat passengers, people driving behind it or next to it with their windows down. That I'm sure will be a different story but will probably won't be any more noticeable than any other little 4 cylinder car out there on the road today.As a previous owner of a Lightning, I am totally on board for electric and the Harvester seems un-necessarily complicated for "peace of mind." It's not surprising at all that hanging a small four cylinder gas engine over the back axle will dramatically decrease towing performance. Couple all of that with the always present sound in the video? It will be interesting to see how many Harvester reservations convert to orders. Meanwhile, if you are realistic about how most of us use a vehicle, the electric does everything better silently. The 150 mile range quoted in the video was for the Harvester in "electric only" mode, not for the BEV.
