Gravity 75 mph Range

Being an EV owner since 2012, the rule of thumb for me when it comes to range is EPA range minus 30 miles and that’s the realistic range of the EV.
I would say EPA - 20% based on the Air. The AGT at 516 miles becomes 450. Then you are driving between 20-80% on a long drive so 60% of 450 becomes 270 miles or about 50% of the EPA range. Extrapolate to the Gravity and you will be charging every 225-250 miles. Of course, this is much better than any other EV SUV out there on the market.

This is a very rational response. I can't wait to see real world testing. @borski could do it if he had the time.
 
Anyone have experience with what the range hit is from putting roof rack bars on an EV? I recall early Gravity promo photos including a roof rack and a luggage pod. But I don't recall seeing any of that in this years promotional promos or vehicle reviews. Maybe they dropped the idea, because they figure interior cargo is so good that people won't need it?

I personally don't need a roof rack. But I'm still curious.
 
We don't need to guess now.

Gravity owners: what mi/kWh are you getting at 75 mph? I get 2.4 to 2.5 in my Rivian at that speed. The Gravity should do much better.
 
From some of the other threads looks like 2.6-2.7 on average

That seems low even with the larger wheels. I hope it turns out to be better than that. With the smallest wheels (I don't think any or many of those have been delivered yet) it should be much better than that.

The problem is 75mph range means three different things that are not 75mph range.
  1. Driving between 65mph and 75mph.
  2. Oscillating between 65mph and 85mph.
  3. Driving 85mph and looking down at speedometer annoyed when someone slows me down to 75mph.
This is why there is such a large variance in "75mph range"
I'm waiting for Out of Spec and Car and Driver numbers.
 
State of Charge has great range and charging tests too, his recent ones comparing the differences in the Maycan and Escalade IQ range tests doing 60 MPH vs 70 MPH gives a great look at how drastic an effect driving speed has on range. Really looking forward to him getting a Gravity to do a range test on.

He also has great reviews of home chargers if you haven't seen his channel.
 
Not the range test we're waiting for, but C&D published an interesting comparison of EV range at different speeds, with an Air as one of the test vehicles:

The results are not surprising, in spite of the fact that the Lucid Air probably has the lowest drag coefficient.

In particular, (from the C&D article):

The OOS 70 mph range test is good, but I especially like the 10% challenge. They test at 80 mph. The Gravity should do well in that test due to the charging speed.

Gravity will win the 10% challenge, provided there are plenty of 400kW charger en route! The stretch between Idaho and Ohio might be challeging!

It will be top 3, not sure it will beat Taycan and Air GT. Air added 216mi of EPA range in 15 minutes, Gravity adds 260mi (starting from 0% so might be a little less starting from 10%). I bet the Air gets much closer to EPA efficiency than the Gravity does at 80mph. It's going to be very close.

I thought it was very interesting that C&D basically accused Lucid of being overly aggressive in how they calculate the EPA numbers, thus resulting in the relatively low speed compared to the Kia. I'm not naive enough to think that the EPA number is a good way for consumers to compare vehicles, but obviously a lot of consumers do that, and even plenty of professional auto publications.

German automakers' cars tend to have similar EPA and real-world range figures. American and Japanese, not so much:
