Title: "Classic" SR vs New SR battery and range
Post by: domingo3 on April 22, 2023, 06:28:11 AM

The original SR with a 14.4 kWh pack claims a range of 90 miles at 70 MPH. The new SR with 15.6 kWh pack claims 84 miles at 70 MPH. I know the new platform is bigger/heavier - is that the full reason that the range claim has dropped while the capacity increased, or did Zero decide to be less optimistic? Is the battery chemistry the same between the two battery packs?  Anyone know if the cell voltage at 100% SOC on the 14.4 battery corresponds to 100% of the 15.6, "110%" of the 17.3 or something else?

What else am I missing for an apples to apples comparison of the battery and range?

Thank you.

Same reason the SR/S didn't have the range of the original SR (or the S with the 14.4kWh battery).  Heavier wheels and fatter tires create much more rolling resistance than the smaller wheels and skinnier tires of the older model.
