R2 - Real world 259 mile round trip efficiency results

[SANZC02]

Charged my R2 to 100% and headed out to the desert to see what traveling in the real world would be like in the R2.

It was a hot day when I left it was 89 degrees, 35 miles in I was in triple digits, it stayed in triple digits for most of the drive dropping under 100 for the last 20 miles. Out of the 259 miles 200 was in triple digits much over 108 and topped out at 117. I did spot check the battery and motor temps, apologies for no pictures but I never saw the motors go past the halfway mark on the lines when I checked. Highest battery temp I saw was 119.

The HVAC system worked well. It was a cloudless day so 100% sun and we got on the road at 11 am and was back just before 4:30 pm. While driving had no issues maintaining a comfortable interior, used manual, temp was set at 67 and fan mostly on number 3, we did use the seat coolers as well. We did stop for lunch before the return trip. It was full sun and 115 degrees, so it did get warm in the cabin, we lowered the windows, put the fan on high for the first couple of miles to the freeway, on the freeway rolled up the windows and the cabin was comfortable within 5 minutes, set the fan back to 3 and we were good for the ride home.

Now for the drive. Used conserve for the entire drive, at 100% it estimated 334 miles.

The drive was 252.9 miles, all was highway except for 9 miles. If anyone is familiar with SoCal freeways were 405/55/91/60/10. Drive was North Orange County to the Coachella Valley and back. Arrived back with 10% with an estimated 32 miles of range left. That could get me around 285 miles in normal highway driving.

I was using Universal Hands Free for much of the trip. I make this drive frequently so it was a good test for me. Compared to highway assist on my G1 R1S there were a few places where lanes split or construction corrected lines where the R1S struggles, the R2 handled those places very well. By the time we returned home I was left with a very positive feeling towards UHF, will be curious where they take it from here.

The car was comfortable and quiet, we used the soft suspension setting in conserve, it smoothed out expansion strips but still held the road well. Based on this test (no charging today) I think it will be a decent road trip vehicle for us. I was hoping for a 2.8 m/kWh average, it ended up at 3.2 which is almost 1 full mile better than the 2.25 I usually see in the R1S.

this was the destination total at the turn around

Good to hear from a different range run. Dropping to a slower speed really helped add some range. I could live with that amount, sure I live in an 80 mph highway limit but it's also fairly open and it's possible to slow down if needed without causing too much hazard.

Yeah we've all heard it. The R2 is a box and is going to struggle pushing against the airflow when speed increases...

Interesting data point but noticed a relatively low speed (certainly not a 70mph test!)

You can never go by average speed on the screen. If you stop at all it counts that as 0mph and drastically brings it down, same as stop and go traffic. Tom mentioned this in his test too. The avg speed is usually higher then shown bc of this. Great test and info either way!

Not every test needs to be 70mph. There are plenty of mountain roads near me that are 55 mph with 30 mph turns. You're not going to average high speeds on those.

The first part of the trip out had a higher average speed and a better m/kWh.

It was over 110 out there, The 8 miles driving around there and the high temps hurt the average speed as well as the m/kWh with the BMS maintaining the systems. I usually park in a garage out there but was running errands so the vehicle was baking in the sun.

Many of my trips average in the mid 50s low 60s by the time I get home. These are a couple of R1S trips.

Considering temps, your HVAC settings etc - that's impressive IMO. Thanks for sharing this.

It's nice to get some real-world California data this early. I feel better about the range given the distance you covered while pushing the HVAC in triple digit heat. My usage will probably be very similar (but hopefully a tad cooler outside!).

Can you tell us exactly what speeds you were driving at?

Sure. In those conditions my Gen 1 Quad gets 330+ miles despite only EPA rated for 275. But we need a bit more info about what these test conditions actually were

I understand being at zero and it’s affects, this also occurred on the OoS tests and their average speed was still around 68 mph due to distance.

Agree not every test needs to be 70 which is why OoS did multiple speed tests. 70 though is one of the more common as people travel along the interstates (if not faster).

Pretty sure this poster was doing at least 70 on highways in SoCal. 405, 10, etc. it’s pretty maddening to do much less. But in real world driving, even traveling 75-80 on highways, nearly NEVER results in an average speed of 75-80 over 1-2 hours.. and certainly not with any traffic, interchanges, small stops etc.. so in a real world simulation an “avg” from a point A to point B over 121 miles, sure the avg was 62.

And total trip included whatever at start or at destination most likely city and urban driving conditions which were stop start, and more regen. but all of which pull down avg.

I’d be interested to know from the OP what was their MAX speed at any point, 405, 10, 55 whatever they took and for longer 10-20 min sections of the driving on those roads, certainly coming down into the desert from Cabazon what were they doing on the 10 heading east.?

This is a real life test and exactly a route I use. Very useful data points
