    Do you consider the Mach-E an SUV?

    and always loved the P1800. The Saint, and up the street where I grew up.

    Do you consider the Mach-E an SUV?

    thanks! But thought the conversion of of a 4 door Model 3 to a wagon was referred to as a shooting brake?

    Do you consider the Mach-E an SUV?

    or a shooting brake. UK. I don’t know or understand the origin

    Do you consider the Mach-E an SUV?

    it’s not longer. Longer wheel base, yes.

    Unlocking extra 3 kWh for early Mach-E's

    Here is an early estimate of capacity and buffers before we had real data from vehicles. https://www.macheforum.com/site/threads/mach-e-extended-range-battery-buffers-and-dcfc-limits.2431/ the charge curve estimate was pretty optimistic :/

    Unlocking extra 3 kWh for early Mach-E's

    So I think I am agreeing with you ;)

    Unlocking extra 3 kWh for early Mach-E's

    The ER battery has 288 Ah total charge capacity. At a nominal voltage of 342 V, that is 98.7 kWh of total energy capacity. as delivered, 2021 ER had 88 kWh of useable energy with the rest of the capacity used as buffers at the top and bottom of the battery charge, imposed by software on the...

    Calibration change info in EPA 2023 certification docs

    These docs from https://dis.epa.gov/otaqpub/ (which I have posted about in the past but not recently) often contain quite a bit of information, and are somewhat hard to decode and understand. As is often done, the (zero emissions) certification of newer models is based on the testing of previous...

    Flooded EV Catches Fire

    Much higher electrical conductivity compared to fresh water.

    Anyone familiar with the i3?

    The REx i3 did not have a heat pump due to the fuel tank but the BEV versions did have a heat pump.

    Anyone familiar with the i3?

    I am not as familiar with the Bolt as I am with the i3. The Bolt has much more range but is also much more of an economy car - which is good for costs and service. If you have an opportunity to test drive an i3, I would recommend it! The Bolt is probably a more practical lower cost option, but...

    Anyone familiar with the i3?

    I got a 2014 i3 (first year) in 2015 with 1100 miles on it. I had the range extender REx model, and used that on occasion, since the EV range was about 70 highway miles. My son in Flagstaff took this over after I got my job 1 MME AWD ER in 2021. The early models had 60 Ah battery, about 18 kWh...

    Darren Palmer: 5-second limit on full power acceleration will be "changed"

    and the GTPE has higher torque but the same power as GT from higher maximum inverter output current (below motor base speed), and not any higher maximum battery current.

    Darren Palmer: 5-second limit on full power acceleration will be "changed"

    Remy hvh motor plots! see this for results from a pretty simple accel model https://www.macheforum.com/site/threads/mach-e-gt-acceleration-modeling-shows-possible-performance-capability-of-the-gt.9599/

    Who builds the EV Motors?

    As stated on BorgWarner site quoted earlier, BW makes the case/casting and the gearing for the rear and front GT, others make the motor and the inverter. I think the MME motors are made by LG, and the inverters come from Hitachi. Doesn’t really matter, it’s all typical automotive supply chain...

    Gas for emergency?

    The idea is not new. GM EV1 ~1997.

    🔥 PSA: AVOID 14-50 extensions! What you need to know.

    It’s not about inductance - the cable is generating heat from resistance and current flow. It’s about surface area and convection to air. there are plenty of pictures of extension cords melting when coiled up.

    Peeking in the electronic brain of the Mach-e: How does energy flow?

    Great data! The motor power and torque specs are the motor mechanical output, that then goes into the gear reduction, differential, axles to the tires. These data line up pretty well with my initial acceleration model - see...
