Re: Build Thread: Performance e-Golf

Sorry for the lack of replies here guys. Our shop has been pretty stacked and getting my own car worked on is a cobbler's shoes scenario I'm afraid. Springs are here, waiting to go in and the Revozport Aerokit from the E-Trophy cars is on the way.

One update on range and performance. If I'm in the right conditions, some traffic, being somewhat conscious of range, I can still average 4.5m/kwh and get over 80 miles out of a charge which is what the car was doing long term before I modified it. However the faster I drive, the more the range diminishes, I'd imagine the relative effects from the extra rolling resistance, like aero drag, are much greater with speed.

Has anyone tried this chip? I might check it out

If that still doesn't do it for you, try better pads.
I agree, I drive spiritedly, but try to focus on balance so don't get into a ton of heavy braking scenarios. That said, if I've ever had a panic brake situation, I haven't had an issue and the extra grip from the tires definitely helps on both braking and acceleration.

The thing to remember when you go to bigger brakes (and wheels) is your adding unsprung rotational mass, which is the worst weight you can add for performance and likely has an even bigger impact on EV Range. You might get better braking, but you'll lose acceleration. If you can accomplish the brake feel you are looking for with pads, skip the big rotors and calipers.

I am now on Egolf #2 (2019) with the same issues and wishes (but more power, noticeably more, yeah 2019)...


...Have we got all the numbers posted here in a convenient format ? Stock wheel alone, stock + ecopia ?
Your 17x8 et35 Advanti DST Storm wheel alone, plus tire ?
The other poster 16" ?

Did you guys notice range loss only ? or did you maintain the same weight per corner (wheel + tire) and therefore presumably maintain the same acceleration (or, egads, improve?) ?
Cost of said combo ?
Man, now that I know the 2019 has more power and the're taking $10k+ off the sticker price, I might have to switch gears and get a new one for this build!

I haven't weighed new and old wheel/tire combos, but I want to say the Advantis are somewhere around 18.5lbs, not the lightest in that size, but light for the money. Tires are listed as 21lbs. Seat of the pants I'd say acceleration is better.

Total cost shipped from tirerack was $1,241.07, but I have a wholesale account so add maybe 10-15% to that for retail.

Ok, so I did my own experiment... My goal was to a) get rid of the Godawful stock wheels b) go 17 or 18 to get some turn in with less flex in the sidewall c) Have better braking, especially on wet surfaces or painted surfaces than the stock ecrapia, d) make the car look a little nicer.

I installed the lightest 18" for a GTI that I could find, Enkei TFR or something - 18" per corner, unlike the stock GTI wheels which are a gut busting 25 lbs on average...

Then I made a small mistake in installing "slightly less sticky than race tires" Pilot sport AS3 on it.. I think I should have gone with something way less sticky and with a higher wear rating.... To sort of replicate the ecopia a little in terms of rolling resistance, but I'm an old dog and I always go for old tricks, I.e. sticky tires - they save your ass once, they paid for themselves... Wish there were eco tires in 225/45/18

Results so far:
- The car feels great. GTI like in transitions, less understeer pushing on on-ramps, better body control...
- The braking is excellent now... So is the looks (to my eyes)
- The acceleration is preserved: So at low speed, the light wheel + heavier tire yields about the same combo of rotational mass and unsprung weight as the Astana+ecopia, so the car STILL scoots at traffic lights...
- However, on the freeway, the grippier tire resistance and size wreaks havoc on my range. I thought I'd mitigate that with the light wheels and it did, for acceleration, not for resistance... I've lost 15% range so far... I'll have better numbers by week's end when I can replicate the exact commute.

I should say I do not care or iota about the range loss, it was expected... On my previous Egolf (2016_ I put in sticky tires on the stock wheels and lost 10-15% range already, and some responsiveness on take off... so I'm not surprised here, the light wheel combo helped preserve responsiveness but I'm still eating humble pie on range. Don't care ;-) But it's good info, I think.. Seems like non-green tire kills range way more than tire size in the end.

I wonder what that 15 to 20% loss of range does to the warranty on your battery. VW would probably void it, cause it beats the sh i t 20% more than your already spirited driving does. Kind of like a power user with an Apple I-Phone that wonders why their smart phone battery is dead in 18 months.

You asked the same question when I put sticky tires on the 2016. There were zero issues under warranty and zero issues upon return, and the car was accepted with the replacement non-eco tires... The person who took the car back told me they did not care what tire was on the car as long as it was the same size and with tread, said ecopias are good for range but not a requirement.

So as far as I know VW doesn't care. I imagine if you thought you were getting a battery warranty issue, you couldd reinstall the stock wheels/tires and look innocent - they have no way of telling what wheel/rubber you run, lower range could be ascribed to a heavy foot or usage of all the doodads (wipers, heated seats, etc)...

You do know VW puts a black box in every one of their vehicles. Pretty much logs everything you do, parameter wise.

No I don't know about the black box but I'll tell you it is impossible for a black box to know I changed from a 16" wheel to a 18" wheel, there's no sensor attached to the wheel, best it can do is measure effort at the motor (which can be attributed to stickier rubber) or do a wheel rotation vs speed measurement which only gives them a wheel+ tire diameter (which is damn near identical overall), again at best they can guess you may have changed tires at some point , if they cared... The dealership made clear to me they don't give a fig.

Anyway it's all moot because it's relatively insignificant per my latest checks...

So my average miles per kw for the past 2000 miles on the craptastic 16" astanas+ecopias was 3.6 (I bet some of you just choked at that). That's using the car "normally", AC, heat, defrost, seat warmers, and driving like I stole it, with steep hills too.

My morning commute is faster and cold (early AM, 80+ freeway, then emptier city, heater, defroster, heated seats on) = 3.0 mi per kw
My return commute is slower and busier, but no AC in general: 3.8 mi/kw
My new commute average is now 3.3 overall, vs the 3.6 before... So the loss is actually less than 10% which IMO is minimal vs the benefits in handling overall. I really think the lightweight wheels helped a lot - people who just plugged GTI wheels (25lbs each) reported more losses.

What is obvious is that the bigger tire footprint + non aero wheels are at more of a disadvantage at freeway speeds than at slower speeds... So if you do 80 miles of FWY per day you are looking closer to a 20% loss with 18" wheels... If you do city only probably less than 10% overall, almost negligible..
For my average I'm happy... Mostly because the E-golf has that dual personality, it scoots from a stop like a sports car, but corners like a horse carriage. Now it's more homogeneous... Probably talking to the wrong crowd but this is the performance egolf thread ;-)

Why are you lurking around on "Build Thread: Performance e-Golf" thread? Aren't you supposed to be drafting behind big trucks on the boulevard at 6.5 kWh, below the speed limit? Not everyone wants to collide into your driving habits. Many of us love to spin tires, rail corners, upgrade the suspension. God forbid, anyone replace Ecopia EP422 PLUS. Nazi is coming after us because we replace wheels and tires. Germans are going to void the warranty for spirited drivers that average 3 kWh :shock:

Not singling anyone out, but here's a quick tip: when an irritating poster is constantly interrupting your thread, or really any thread, click on their name and select "Add Foe".

It really will improve your quality of life. The only time you have to read their drivel is when someone else quotes them, then you can remind that person how to do this.

I might consider some performance tires upgrades for my Ecopias, provided they provide more miles per kWh than the stock tires.

Bringing this thread back, finally got around to installing H&R springs this week. Install was pretty straight forward, but I definitely have some suggestions if anyone is looking to do this install themselves. Ride quality feels about the same when hitting bumps and dips in the road on stock wheels. I don’t feel like I’m sacrificing comfort at all, but haven’t driven much so far. New wheels and tires should be coming this week, I’m following zanzabar’s lead and going with the Konig runlite in 16”(I wanted 17s but there aren’t any in the US).
