My first 10,000 miles are done in my 2023 R1T Quad Motor Large Pack. It's a phenomenal vehicle. Best I've ever owned.

I averaged 2.03 mi/kWh per the trip meter over this 10k miles. Converting back to kWh/100 mi results in 49 kWh/100 miles. This exactly matches the EPA estimate. I made no efforts to conserve energy or drive conservatively. I drove it like anything else I own, most commonly in sport mode. I drove up to Lake Tahoe and back repeatedly and in rain, in snow, in cold, and in heat. I also did a lot of local 1-5 mile trips. Overall, this may be the first vehicle I've ever owned that actually met its EPA rating.

With that said, I'm not sure how 135 kWh battery pack / 49 kWh/100 miles = > 300 miles. Per my math, it's closer to 275 miles of range. This seems to be in line with that I actually got, but the in car displays and advertised mileage often exceeded 300 miles. Curious to see what everyone else has averaged over that many miles.

The new R1 v2 has also made me take another look at this information. I believe it's < 40 kWh/100 miles. if so, that's a > 20% efficiency improvement! That helps make the large pack reduction from 135 kWh to 109 kWh make sense. Range would be nearly identical for 39 kWh/100 miles consumption with 109 kWh battery vs. 49 kWh/100 miles with a 135 kWh battery.

Interesting. I’ve been able to realize EPA MPGs in my VW diesel, LEAF, Bolt, Pilot, Lexus, and Bronco. Are people not able to hit EPA normally?

I depends how you drive. As you know, speed kills efficiency in BEVs. So high speed highway driving will never meet EPA range estimates.

Tim, 2.03 mi/kWh x battery capacity at 100% is not EPA range, right? I think to meet EPA the efficiency needs to be much higher, closer to 3 mi/kWh.

We got 2.04 with over 30k. On our 2022 Quad. This includes thousands of miles of pulling our camper at 1.1-1.3 on 22” tires. Btw, we just traded for a PDM Max Pack. On a road trip currently. We got closed to 348 miles on the highway yesterday. Ideal conditions..82 degrees and ~76 mph.

Agree. The smaller EVs spoiled me. They have efficiencies in the 3-3.5 miles-kwhr. I think the EV9 is around 2.5. Yes, the 3 rows are huge and square so I get it, but just saying.

My diesel Passat back in the day was a beast. Nice drive and I could get 45mpg. Would go from SF to LA, drive around, and get back on one tank. And I drive fast as hell. Of course, there was diesel-gate and I was spewing 40x the NOx I thought I was, but…..lol

I'm over 2.5 in my T now that spring/summer are here, so in the ballpark of 352 stated. In the winter it's lower as it's cold, but preconditioning plugged in changes that dynamic impressively well.

My lifetime average across ~16,000 miles in my 2023 R1S (large/quad/20"AT) is currently at 2.35 mi/kWh, so I feel like 2.5+ should be doable on more efficient tires.

However, I'm mostly chiming into say I feel the same fondness about the VW Golf TDI that I drove back in the day - probably the most fun & economical vehicle under $100k MSRP that I've ever had, even if it was in fact destroying the world behind the scenes. 45-50 mpg on the highway and was as nimble as a Miata.
