  Im 6 months into ownership of my Equinox EV RS AWD.  I absolutely love the vehicle AND Super Cruise as well.  When I see the collective experience of these engineers, and the thoughtfulness they put into the machines they craft, I have even more confidence in the new GM.  Well done!  And thanks for even coming on to talk about the processes and logic behind the design decisions.  Happy customer right here!

  Yes, GM made with it&apos;s Bolt allready a very efficient e-motor (IPVMsynRM), in particular in the low load and low rpm. Another point which I can tell you from my own experiences with my Bolt EV. Don&apos;t put so much big heavy tires and rims on them if it is not needed. I can tell you to change for the 2017 Bolt to go to 15 inch rims, steel rims. There is about 4-5 mm between the brakes and rims, but you don&apos;t need a lot of air for cooling, because I am using only regen to stop. I only use brakes for emergency, which never happened over the last 4 years driving the Bolt! I made the tires less wide, increasing safety and improving resistance against water aquaplaning, and also increasing efficiency. Everytime the car hits water puddles it is costing energy, and with less wide tires you will pass water puddles with much more easy and using less energy. Cast aluminium rims get easy scratched by curb stones, and any scratch is a mechanical notch leading to loss of strenght of steel structure. Increasing side wall by rubber tires you get better safety, and there is no loss of strength touching scratching curb stones or pot holes. (note, you need good maintenance and proper cleaning brake disc surface, I do that with wd40 and abrasive spounce 3M. and keep all the rubbers there well lubricated as well with silicone).<br><br>I choosed Goodyear Vector 4 Seasons Gen 3 size 195/65R15, on steel rims: 15 inch, 5x105, 6,00J&quot;; ET 39; bore 56.6 mm. With this ET the tires are less sticking out of the side plane, not negative influencing drag coefficient. I keep the tires at 2.6 bar pressure, cold tire pressure, it will give good comfort at bumpy roads. The rounded end part at the tires are also increasing drag coefficient.<br>I am getting 500 km range in summer at 22 Celcius with no wind and not using any heating/airconditioning out of the original 58 kWh battery.<br><br>Just done a trip now of 130 km through the province at speeds around 70 - 80 km/h and consumed 10.8 kWh/100km, with steering wheel heating and chair heating on, but the cabin heater off. Good comfort and it is outside 12 Celcius.<br><br>The tire changes is very important because now if I am not cruising faster the 90 km/h my efficiency is the same or better than Tesla Model 3 from 2017-2019. I hope you can improve also on better tires at new cars.<br><br>It is very important too for the battery. My Bolt EV does not have DCFC. I learned allready earlier that Fast Charging is wearing out the High Voltage battery too much, which I can confirm. I keep the battery around 50% when I am only driving short trips in the city. When I am driving longer I charge up to 70% or 75%. Only when I am driving long distance I charge up to 90 or even 100% but plan the departure. It doesn&apos;t stay at full charge for long time. All this practice is leading to less battery degradation. When I am doing long trips, I drive constant speed of 85 km/h with the trucks, and occasionally increase to 90 km/h just to repositioning the car for other traffic. There are no high loads to the motor and battery, and I get a very good data input for HV Battery degradation testing measurements. The car is 8 years old, but still got 54 kWh (winter measurement) 58 kWh (summer measurement) capacity remaining. In winter, pre-heating the car with power from the grid before departure will give at temperatures around 1-3 Celcius, and using heating comfort, a total range capacity of 350-365 km. Getting high efficiency is very important to get to destination without DCFC.<br><br>All EV cars using DCFC have some degree of battery degradation. I just learned that cooling into a HV battery on a 2019 Tesla Model 3 learned to created condensation moist inside the battery. That moist cannot go anywhere, and will corrode battery cells. And there you go, that is you battery degradation. You must replace battery cells. Since I don&apos;t use fast charging, the Bolt battery get not cooled and there is no condensation inside, because the termal system is only heating in winter, during charging and when the car is plugged in the power grid prior to departure, to heat up the car and cabin. In full summer I have seen temperatures around 42 C inside the motor compartment, while the car was parked at a very hot sunny location, and still the battery was not cooling. It learned that the temperature inside the battery was around 32C and the car liked it. My efficiency when driving was also great that day. I just hope you take such factors in review.

  As the proud owner of an Equinox EV, I&apos;m happy to hear from the engineers who designed what I believe is an outstanding powertrain. When I first test-drove the Equinox late last year, I was impressed - here is a vehicle that is quiet and powerful. I was made an offer I couldn&apos;t refuse in July of this year, and have been absolutely thrilled since. Well done and thank you!

  You conveniently forget to mention that the BYD engine is from 2013 and the Chevy&apos;s is from 2025. Your comparison is really fair, you are very fair.

  Kudos to the engineering team at GM on this very complex interdisciplinary development work. &nbsp;I used to work as an engineer for an automotive supplier, and I was always impressed by the level of rigor that GM demanded in the development process. &nbsp;I have 20K miles on my 2025 Equinox EV, and I really like the vehicle. &nbsp;I also like never having to go to a gas station in the dead of winter or having to think about oil changes 😊

  Brilliant! purchased my 2025 EQEV LT1 10months ago and i&apos;m very satisfied with it. Thanks GM and Munro.

  Taken delivery of a new 2026 Cadillac Optiq 700E4. GM and specifically Cadillac engineers re-did the powertrain on the Optiq for 2026, where the old 2025 Optiq shared the same same Equinox EV AWD setup as shown here, the new one gets a &quot;larger&quot; PMSM motor derived from the Lyriq &amp; Vistiq and the new 440hp &amp; 498lb/ft torque absolutely makes it fly. Kudos to the GM engineers for this brilliant engineering and at a price tag that is FAR less than the German &amp; Korean competitors.

  Thanks to all this informative and critics reviews, I bought what they recommend 30k equinox EV LT That was a bargain for all they offer, same batteries, and same powertrain. Than the other more expensive variance (Cadillacs and Hondas) for only half of the price . Thanks, Monroe
