Thanks for the real data points! Unfortunately I don't think I ever figured out the original useable capacity when I 1st bought my car, also a 2014 w/o DCFC. I just got Torque Pro and the custom PID's figured out and it claims I have 16.2kWh total capacity. Which obviously doesn't agree with...

Lol, guess I'm hoping for my battery to fail harder. Also, FYI, I just read through my entire Owners Manual and Warranty books and there is no battery capacity specification anywhere...

The lack of concrete battery warranty data is annoying. i.e. 35% after 8 years of what original capacity? That should translate to a known fixed value which should be publicly acknowledged. The original marketing specs were for a 21kWh battery. If somehow, the "useable" is less (and...

Thanks for all the info. May I inquire where the "official" battery degradation warranty info is? 35% degradation in ~ 5 years seems pretty excessive, and had I understood that from the get-go I might have been less inclined to purchase the car outright...

I am the original owner of my 2014 Spark EV, bought in Oct 2013, just ticked over 40,000 miles. Just got back from a short trip and noticed the battery capacity is seemingly getting rather low. By my maths this equates to ~15.3kWh capacity. Time to get it checked at the dealer? What is the...

How are you guys determining maximum battery capacity?

I guess I should have noted that even pushing the Spark "almost" as hard as I could for a full practice session, I had no overheating or power reduction. So I guess it's got that on the Teslas ;p

Even though I've raced on Laguna Seca a number of times, I always find it helpful to brush up in a simulator before going out. iRacing is incredibly realistic and really helps to identify the proper lines.

Took my Spark EV to ReFuel. Unfortunately due to lack of decent charging options I was only able to run the 1st practice and the main TT. I also did a 1/2 dozen autocross sessions. Fortunately I also had a Palatov DP1e to drive :) Got a 2:11 for my TT time, beating out all but a Fiat500e (by a...

http://www.refuelraces.com/ Anyone gonna challenge me for fastest Spark lap times? :)

It's an annoying "pulsing" at a couple hertz as the car brakes the rear inside wheel to pull the nose around. Also the stabilitrack indicator flashes when active. It does work. But it's way over-active in this car, I suspect I have 50% "grip" left before it really needs to actuate this system...

So I commute in the Santa Cruz mountains on a daily basis and find the stabilitrak to be wildly over-sensitive. I probably trigger it 1/2 dozen time every trip. I am not pushing the car that hard. There is one corner in particular that seem to trigger it even at very mild speeds. I estimate less...

Hey TW, Heh, I disqualify your results on 2 counts. A. it's a leaf B. it's extrapolated. I could stand on the pedal for 5 seconds and extrapolate that out to some ungodly low M/kWh. I've been out at Refuel the last 3 years on Zero's and last time I also ran an electric kart @ 1:48! I doubt...

After a hard nights flogging in cold/crappy conditions I had a mere 62 miles faull charge range estimated this morning.

That's what I was saying. They are claiming 105kw "mechanical power" though they fail to state if that is at the motor shaft or what. So yeah, if they are getting 105kW at the motor shaft, or even better at the wheels, with 120kW input power that is 87.5% Total System Efficiency. Not too shabby...

Nice job antagonizing your range estimator :) I also want to autocross my Spark EV, how'd yours do? Figure out how to turn off the stability control or anything? Any mods? I will be entering the refuel TT at Laguna Seca with my Spark this year and I'd love to have this thing dialed in a bit...

Check this thread, I posted some data which lined up nicely with motorotrends review. http://mychevysparkev.com/forum/viewtopic.php?f=9&t=3563 To your other point. RPM and Torque are just components of Power. Gearing will get you any RPM or Torque value from any amount of power, but not vice...

EV power is almost always claimed as "BATTERY POWER". That is the power the battery is delivering. You will lose at least 10% of that in even the most efficient vehicles before it comes out at the contact patch of the tire. The spark motor is probably in the low 90% efficiency range, the...

Just curious who's got the lowest Fully Charged Range Estimate? I commute "very" aggressively, I have to, morning rush hour is like 80mph. I only have about 30 miles to work and I can re-charge there so I really put the hammer down ;p Combined with cold weather and associated climate control...

Just wanted to say GM has been very helpful. They sent out a service tech, he pulled some logs and then "reset" the car by unplugging the 12v battery for a minute or so. This fixed the issue and seems to have retained all my settings and such. So I'm not sure it's exactly "fixed" , but at least...
