Rivian R3 profile image

Electric truck and SUV manufacturer Rivian announced their new R2 SUV today, but surprised everyone with a smaller R3 version as well. I love smaller cars and I’ve been waiting for new smaller EVs to hit the market, hopefully at a lower price point. The R3 looks adorable and it reminds me of a VW Rabbit, which I used to drive.1 But Rivian didn’t publish any specs so it’s hard to gauge how big R3 is.

Thankfully, they provided high res imagery and it’s easy to see the tire details — Pirelli Scorpion MS 235/55 R20. So based on a 20-inch rim size, and with a nice profile shot,2 it’s possible to estimate the size with a little bit of simple math.

These numbers are rough, obviously. But here’s what I got:

Rivian 3
Length: 149 in.
Height: 55 in.
Wheelbase: 102 in.

That length looks a little short, but as you can tell from the picture, there is very little overhang in front or behind the wheels. For a point of reference, I compared those numbers with the specs of another EV model that I like a lot:

2024 Hyundai IONIQ 5
Length: 182.5 in.
Height: 63 in.
Wheelbase: 118.1 in

The Rivian R3 looks to be a good bit smaller than the IONIQ 5 in all dimensions. In fact, the R3 looks closest to the size of a four-door gas-powered Mini Cooper:

2024 Mini Cooper Four-Door
Length: 158.5 in.
Height: 56.1 in.
Wheelbase: 101.1 in

Of course, there are lots of caveats to this comparison. My numbers are rough, the car is a prototype, and things can change as the car moves to production. Who knows when it will be available to purchase, but I’m excited about the Rivian R3. I’m not in the market right now, but my next car purchase will be an EV. That size is actually perfect for what I want – a small EV to commute back and forth to work. Now we’ll see where the price falls.3
