I had 500e for about 8000 miles or 11 months.Interesting observation. Every road test I can find shows the Bolt about 2 seconds faster 0-60. If the 500e comes off the line harder, it must drop off rather quickly.
No need to apologize, it was an informative read, even for someone like me, whose gear head days are long gone. 😁I had 500e for about 8000 miles or 11 months.
Bolt is... I compare it a turbocharged engine powered car. There is always some turbo lag. That's what Bolt is.
500e - there is no power build up. You press the accelerator - it gives you all of it. Right away.
In Bolt - I can see that the moment I depress it, say at 60% travel, and power comes, gauge shows 45 kW and it building up to 110 kW and will keep it there. Sport mode will make this happen at a lower travel depth, but overall power build up is faster.
In 500e - I press it and expect 65 kW - it gets there within fraction of a second. I mean, literally - it is less than a second.
Comparing Bolt to 500e - the latter will have better jolt experience.
Now 0-60 - yes, 500e falls with power quite quickly. Till about 40-45 mph it has good pull. Anything above - still goes, but Bolt takes big advantage.
When I did (several...) hard pulls - 500e you feel 0-25 mph is quite strong, more torque is released at 25 mph so it gets even better, but once you pass 35 mph torques starts tapering off. Hence it does not feel so strong anymore.
Bolt, gives a little jolt (nothing like 500e) and starts pulling. About 30 mph more torque is released, and it keeps pulling, it keeps going. 40, 60, 80 - the power is still there...
Funny, Bolt feels like my Kia I had previously.
It was Forte5 SX equipped with 1.6 Turbo GDI. It was a tiny, but with a high torque engine. almost 200 lb*ft down from 1750 rpm. Man, it would eat tires.
But above 50 mph it felt somehow weak.
So I tuned it. I thought - well, why not... Supposedly 200 lb*ft became 250, 200 HP became 235-240.
But what mattered was when and how the torque and power were available.
The tuned version felt like Bolt comparing to 500e. It kept pulling past 60, 80, 100 (all mph). It felt unstoppable. I gave up at 110 mph as the turn was coming on the track. The straight was too short. Or so I thought.
So yes, Bolt is overall faster than 500e, but Fiat gives more fun.
I bet Chevy could do very same thing, but they programmed the controller to limit power.
Oh, how do I know about extra torque at those speeds?
One thing - the net. You can find how info on torque limitations in lower speeds for both.
Second - driving on wet.
I can start with pedal to the floor or maybe at 80%, have grip all the time until hitting 25 mph with Fiat or about 35 mph with Bolt when all of the sudden I start loosing grip.
Great indication of torque limitations...
sorry for long post
That might be, Mike.the Bolt has to be out-accelerating it before 30 MPH in order to make the same 0-30 time.
I'd never felt anything like it before, nor have I since. The '97 PbAs would jitter all over the lane if you didn't hold on to the steering wheel like your life depended on it. Mind you, it only did this if you put your foot into it. I put my foot into it A LOT!So, I pushed it several times, at different rates and loads.
No noticeable power change.
I could feel some power fluctuations, but those were grip and torque limiter related (I bet there is some limiter via software as I could feel more acceleration after 35 mph).
Other than that - nothing. I was at about 70% SOC, so enough juice.
It was cold, though, about 5-7 C (40 - 45 F?).
So GregBrew, you are saying EV-1 was even funnier than raw 500e? I never drove Tesla, so I cannot compare, but 500e feels more powerful than Bolt. Sure, above 40 mph Bolt gives more oomph. But from dead stop - it will not even spin tires. I can get some chirp at 30 mph, but dead stop.
TC on or off, Sport on or off - almost same take off.
It appears that they (GM) changed the ramp-up speed for maximum torque allowed from the motor, which reduced the torque steer at high accelerations from a stop or low speed. IIRC, the 0-60mph time was reduced a smidge in the '99 NiMHs as a result.Wait, they TONED DOWN the torque steer???
I did not complain.It always strikes me as funny when people complain about torque steer.
That's because the Bolt engineers minimized it by using equal length half-shafts. More Torque, less Torque steer, better engineering = better driveability 🙂I did not complain.
I found it very amusing and funny. I miss it in Bolt.
None of other cars I ever owned (majority of them FWD) had so much torque steer as Fiat.
The very first time I was a bit surprised how it pulled in a turn under load. But then it was pure fun!!!
The Bolt has equal length drive shafts FYI.

The axle stub that goes through the center of the armature is irrelevant as far as torque steer. The CV joints in the axles are in completely symmetrical positions side to side.
Just because you notice torque steer in all the Bolts you test doesn't mean it comes from where you think. The Bolt axle configuration is ideal for minimizing torque steer in a transverse mounted setup. The minimal effect caused by differences in torsional stiffness side to side as a result of the intermediate shaft are only transient and not at all what Bolt really suffers from. Torque steer can arise from many other things like scrub radius, alignment, road crowning, and poor traction from the OEM tires.I tried to edit my claim in time, hence the weird post, however since it's too late, I'll leave you with:
While batteries get a lot of attention, drive units in electric vehicles don't get as much love. Why? Because many think they're simple and all the same. An electric motor turns a reduction gear of some kind, which turns the CV axles, which turn the wheels and makes us go. It's just a few moving...cleantechnica.com
"One axle shaft is much longer than the other. While the CV shafts are of equal length, having uneven axle shafts like this does contribute to torque steer in unavoidable ways. In the Bolts I’ve tested, this is quite noticeable"
