Real World Hwy efficiency numbers

[Wannabeskibum]

So, for those lucky enough to already have a Gravity. If you have done any long-distance driving, would you mind posting efficiency maybe with tire size, speed, and weather if meaningful. I'm most interested in 80 mph in cold weather but being the middle of summer what can you do.

I'm also looking forward to cold weather efficiency numbers. A big part of the Gravity's appeal is a range rating big enough to still provide a great range after cold weather, a heavy foot, and a bit of battery degradation have all taken their toll. Maybe one of our Argentinian brethren will get a vehicle and report back.

So far my GDE gets 2.74 miles/kwh over 600 miles. In hot sun in south Florida about 95 degrees when driving. I have 22/23 wheels. Most of these miles were on the highway at 75-80mph. Not that impressive so far. They do say in the owners manual that it is not as efficient in the first 2000 miles. The GDE with these wheels is only anticipated to get 370 miles on a charge. I believe that a range of 370 for the GDE with the large wheels is a best case scenario driving like your grandmother. I am getting closer to 335 miles

And for fun I put the AI version of what I wrote: So far, my GDE has achieved an impressive 2.74 miles per kilowatt-hour (kWh) over a distance of 600 miles. During this journey, I drove in the scorching sun of south Florida, where the temperature reached a sweltering 95 degrees Fahrenheit. I’m equipped with 22/23 wheels, and most of these miles were covered on the highway at speeds ranging from 75 to 80 miles per hour. While this may not seem particularly impressive at first glance, it’s worth noting that the owner’s manual does mention that the GDE’s efficiency decreases in the initial 2000 miles. Considering these factors, the GDE with these wheels is only expected to provide a range of 370 miles on a single charge. In my opinion, this is a best-case scenario, assuming I drive in a leisurely manner similar to my grandmother. I’m currently getting closer to reaching a range of 335 miles.

Haa, I'm at 2.6 with the midsize wheels so...

How does the efficiency compare to your Rivian?

How does the efficiency compare to your Rivian?

No comparison. The Rivian is terrible for efficiency. Less than 1.9m/kwh. And the AC struggles. Putting xpel on the windows. The quad and the tires really kill efficiency. But it tows much easier than the Lucid.

After about 700 miles of driving, and LOT of thst show boating and goofing around, I'm at about 2.85 efficiency. Just completed a 200 mile trip that I've done a hundred times and in our other EVs, we'd get that trip done and need to charge relatively soon as they both had upper 200 mile range. The Gravity still had about 45% and another 150 miles or so of predicted range left. I was driving comfortably for me, mix of back roads and highway, doing 80+ on highway segments and moving along briskly where I could on side roads. Very hot in Alabama/Georgia where I was traveling thru, in the upper 90s most of the trip and some elevation changes, but nothing too severe. My GT has the mid size wheels and rated for 385 miles of range. If I settle down a bit, I'm pretty sure I could get that without too much trouble.

Definitely a comparison to be made. I have a lead foot and my lifetime efficiency over 20k miles is 2.5mi/kwh on gen 1 quad with 20’s on 275/60/20 AS tires.

I drove my Rivian from 100% to 0% twice. Just real world data from my life just going to work, errands on the weekends, visiting family etc. All purpose mode took 7 days to die and got me 292 miles. Conserve mode took 9 days to die and got me 343 miles.

Trying to understand your R1S data.....you have a Gen 2 R1S Quad, correct? Your metric of 1.9m/kWh is on highways? 75mph? Was the R1S "loaded" (ie.e, passengers and gears? Weather? Elevation change?

Your 2.74mi/kWh is under the same conditions?

My experience in my quad R1S is different. I routinely get about 2.15m/kwh. I am hoping Gravity is 3+. This is around town, normal temps, no major elevation, etc. If I go to the mountains in winter with my family, I am at 1.6.

I don’t drive like my mom either. I don’t launch at every light, but it’s enough to get my kids gripping the “oh sh-t” handles from time to time.

Gen2 quad with all terrain tires - worst case efficiency. And driving 200 miles from Orlando to Naples (super flat no elevation change. Sea level!). It was 100 degrees last weekend. Just 2 people. Driving in the early evening with so many bugs it felt like it was raining. The car is rated at 325 miles range with this setup. The drive was 75 mph or less. It’s not all highway.

The gravity has been back and forth from Naples to Miami. All flat terrain. I’m actually happy with the result for the gravity. Also just two adults.

Thanks for sharing your experience.

I have a 2022 AGT and a 2023 Gen1 RIS Quad. I travel 3-4X per year between Marin County CA and Phoenix AZ (I-10/I-5). I've driven both vehicles on this strech (~740 miles). The biggest elevation change on this route is the Tejon pass, ~4,100 ft. I don't drve aggressively, ~3-5 mph over the posted speed limit. Typically, I get ~2.4+mi/kWh on my R1S, in "conseerve" mode (FWD only). I don't have all-terrain tires. With the AGT, 19" wheels, I get ~3.5-3.6mi/kWh. I don't have a Gravity. My guess is, it will probably come in at ~ 2.8-3.0mi/kWh onn this route with my driving.

In city driving, I can get 2.8+mi/kWh on my R1S.

Recently, I drove my R1S on 7th St, south bound, from Glendale Ave. to McDowell Ave., approx 5 miles, crusing @ 35-40mph, I hit an amazing 5+mi/kWh in my R1S!

I guess that's not too bad. All Gravity's have the same 123 kWh battery, right? If the EPA is 370 on that config, that's 370 / 123 = 3.0 MPK (mi/kWh). That's 9% off, before it's broken in. I'll be happy if my 450 mile config gets 91% of EPA (409 miles) at 75-80 MPH.

That's a 1st leg (from 100%-10%) of 368 miles.
Successive legs (80%-10%) of 286 miles.

Only time I’ve come close to that is downhill out of the mountains!

The numbers being reported at ~75 mph are actually promising. The EPA test is a composite of 55% city driving with an average 48 mph speed and 45% highway at a constand 60 mph. Driving 75 mph is about 30% less efficient than 60 mph.
