I LOVE it! THIS is the kind of truck I'd be looking at to replace my 1998 Ford Ranger.

Here is what could be potential deal-breakers:

- Lack of a mobile app. Minimalist design is great, but I still want an app to manage charging and be alerted to any vehicle issues.

- Lack of good charge management and battery conditioning. Either that, or a cheap and easy to replace battery pack. I'd really like both!

- Comparable hauling and towing capacity to the 1998 Ford Ranger. Those numbers aren't exactly impressive, but I do use the truck as a truck, and I occasionally need the hauling capacity (weight).

- Bucket seats. I need a bench seat so I can take my wife and dog. Think weekend glamping trips. Picture 8 shows a bucket seat. It doesn't look like that would work.

If anyone from Slate is reading this, this is how I'm looking at this truck. FYI, I'll be comparing this to the Ford Maverick.

Noooooooooo! No apps, please! Finally a car not tethered to and dependent on your phone, and we already have our first request to app-ify it!

EDIT: Ughhh, according to the video that another user posted, it looks like there's an app, and yes, "updates" go through it :(

Yes to a simple battery system!

Yes!

Yes, definitely. It being a 2 seater is kind of a deal breaker for families. You really want a bench seat to at least stick a small child between the driver and passenger. Back in the day, we'd stuff 3 kids between two adults, but these days the Safety People would have a heart attack just thinking about that.

The article mentions an SUV upgrade kit that will bolt onto the back of the truck. Ugh, OK I guess. Sad that that's the way it will probably have to go.

But you realize this will make cold-weather range suck and on-the-road charging suck, right?

Preheating the battery and cabin on "shore power" is something EV buyers just expect at this point because that can consume 2-3kWh of energy (equivalent to 6-10 miles or 10-16 km). That's almost 10% of Slate's range (see below).

Preheating the battery about 10-15 minutes before you arrive at a supercharger is another expected feature. It can increase charge acceptance rate by over 50% (reduce charge time by 1/3).

The 150 mile range is extremely optimistic given the size of the battery and shape of the truck. With just 5% top and bottom buffers, you'd need to achieve over 3.1 miles/kWh... which is the consumption expected of a small aerodynamic sedan. I would bet real money that highway range (at 75 mph) for the small battery is less than 120 miles from 100% to 0.

Highway speeds are worst case scenario so maybe you're right but I doubt it.

Your charge rate acceptance number is surprising to me, I've never seen anything like this in my years of experience designing EV batteries. Preconditioning helps extreme fast charging but isn't necessary for 1-2 C charges at all unless it's very cold out.

There's some caveats to this depending on the exact chemistry but if anything the newer semi solid state NMC cells are even less dependent on this and can charge down to -20C.
