Tesla M3D review: split decision - Laguna Edition
apologies to @Petevb - I thought long and hard about where to post this review. Pete's review of his Model 3 was one of the best reviews of the car I've seen on the internet, balanced, fair, and takes multiple perspectives into account and really captures the "I'm happy and sad for you" nature of Tesla for most people. I'll agree with @Petevb perspective on Tesla that you can simultaneously praise and slam them and they can make excellent cars with low reliability (for some) and still be good -it's an infuriating cocktail of contradictions that is difficult to sort out - there is no one correct perspective regarding Tesla or it's product, and virtually everything said about them is true (all of it!! good and bad) - On the whole I see Elon/Tesla as chaotic-good with a clear vision, but poor execution, but the vision is so compelling that you're willing to overlook the execution flaws, because even in their flawed state Tesla's products can still be good…
I have no regrets with my Tesla patronage and any long time readers of this forum know I'm a passionate advocate for the vision and the products. Tesla produces the best EV's you can actually purchase today with the most capabilities and are the most complete EV products you can buy, all other manufactures today are still missing the total solutions picture (product, software, charging, service, even technical approach). Tesla is far from flawless, but they are trying to do things differently and pushing pushing pushing this whole thing forward. Love them or hate them they have changed the industry…
It is therefore with humility that I'm posting my Model 3 track review by liberally stealing @Petevb excellent observation - cause my experience at the track with my Model 3 is again a split decisions - a glimpse of what is possible for an EV but some frustrating limitations that mean we're still not quite there yet.
I feel my track day review is best taken in context with @Petevb review here - if you read both I think you'll have a good perspective on where we are.

please review and draw you own opinions, I know many on this forum will do just that - but be open minded, I had an excellent and frustrating time … but I'm excited for the future.

Hello all I just completed a track day @ Laguna Seca with Hooked on Driving with my 2018 Tesla Model 3 Long Range Performance Edition - Dual All-Wheel Drive + Performance Package
Some Specs/Facts about the 2018 Tesla Model 3 Long Range All-wheel Drive Performance Edition
Weather at Laguna on Nov. 16th could not have been better - f’ing perfect perfect day at Laguna, a real gem, conditions could not have been better for this test.
Due to Technical difficulties (I HATE GoPRO!!) I only have one session video - but it will suffice and has some limited data (speed, g-forces)
My background at laguna
The best lap time I was able to achieve according to ApexPRO data was 1:50.32
I’m fairly confident I could lay down a 1:48-1:46 lap time with PS 2 Cup’s and different brake pads in this car - a quicker driver might do a 1:42 - maybe.
Lap times for session #3 were
At the 7:48.xx time stamp on the video you can hear a “beep beep beep” - this is the car showing me a new never before seen warning on the main dash screen
I did not try the car with and with out track mode. I ran 3 session (out of 5 possible sessions) - all sessions were done under track mode.
Overall impressions:
The Model 3 handles well and power is ample - at no time did the car’s behavior concern me - handling is stellar for a 38xx lbs 4 door sedan - easy to place on track - this car is really really excellent - just wow!
My overall impression is that the Model 3 is a quick and fun car on track (at laguna) with no stamina what so ever {sigh}. I encountered a few issues with the car in it stock configuration.
Track mode represents a major win and is major progress towards a street EV being a decent track car, but still has a long ways to go. In particular for my circumstance I encountered the following difficulties
The summary is really really easy - there is _NOTHING_ wrong with this car’s dynamics, but it has no stamina. I was unwilling to complete a full 25 minute HOD session in C group (advanced point by passing) due to the following issues -
But the trifecta of:
The car is really really really good for the 1st 3 laps - nothing to complain about - you might be able to recover it and do another 2 laps if you did a 3/10th pace after the 3rd lap - go out do 3 hot laps, do one full 3/10th lap - go do another full pace 2 hot laps? I didn’t try that. But even so I was consuming more than 30% battery for the 5 laps I was doing, staying out another 3-5 laps would consume another 30% battery? I'll never know.
There is a supercharger less than 8 miles from Laguna - you need 8% battery to get there…so a visit over lunch break would easily get you back to 70-80% battery and come back for the afternoon sessions
I gave up on the afternoon sessions because I felt I had learned all I needed to learn from this little experiment - and didn’t really want to flog the car un-necessarily…
Charging choices at Laguna
Thoughts/conclusions/observations in no particular order
But I’m glad I did it…
The car is great, but it’s no track car even with track mode software. Based on my abbreviated 3 sessions at laguna - when Elon claims a track record - I can almost guarantee the car can only do it 2 to 3 times back to back - and then needs a healthy rest before it can do it again - and they will have depleted the battery quite a bit.
The stamina issues can be overcome, and they will be overcome and ICE’s have something to fear…EV cars can and will be very very good, among the best in terms of performance…but the consumption rate will need to be considered if you want to do a track day or weekend - infrastructure at the track will be required to run these cars all day, once they can stay out for a full session.
This car is still an excellent daily driver and I have no regrets, it’s one of the best cars you can buy as as street car - it’s a master of it’s class in this role - and even road tripping with the supercharger network - and it shows the potential of EV’s as a track car, but it is no track car, and won’t be for quite some time, and even it was ready to be a track cars, the tracks don’t have the infrastructure to support it. Some missing pieces still needs to be slotted into place to track this particular EV and enjoy it’s full potential - but the glimpse of what is possible (oh those first 3 laps) gives me hope, and wow it can be sooooo good. Let’s push to get there, but we are by no means done and the Model 3 as some real factual limitation in this role.
The best of both worlds is to drive to the track in your Model 3, and drive your GT3 on track (having it brought there by trailing - hey even tow it with a Model X) - but to go out for 20 minutes or more - I've done 45 min in my GT3 - I just don't see that happening for the current Model 3, even with brake upgrades.
it's still a split decision - but clearly not a track car, but what an enticing 3 laps in beginning of each session - just wow.
Porsche Taycan - I'm coming for you - and plan to do a head to head vs. my Model 3 review! May be a CSS charger or two at Laguna before the end of 2019?
I welcome comments and questions.

68-74 degrees F - clear skies - all around great day
just wow

Due to Technical difficulties (I HATE GoPRO!!) I only have one session video - but it will suffice and has some limited data (speed, g-forces)
My background at laguna
- my personal current best lap 1:41.xx in my 2018 GT3 on Dunlops tires, can do this often so not a fluke - working towards sub 1:40’s - not a fan of the Dunlops
- I’m fairly confident some different brake pads and Michellin pilot sport 2 cups will assist me in my goal - so it’s doable
- past personal historical lap 1:38.xx in a 2010 GT3 Cupcar on full slicks - vs. Simi-pro time (different driver) of 1:32’s in same car - again I’m pleased with my pace
- we know mod’d GT3’s at this track can do low 1:34’x - so I’m not the quickest, but I don’t fully suck either…feel free to disagree - and then try and follow me at laguna
Best lap time for a Model 3 Performance so far is a 1:46.xx https://electrek.co/2018/09/15/tesla...a-seca-record/
configuration of this car is unknown - mods? Tires? Pressures? Configuration? 100% stock?
no track mode software was present on the 1:46.xx car
Randy Pobst’s MotorTrend at Streets of willows review was conducted on 245/32 ZR20’s PS 2 Cup’s (not the stock 235/35 4S’s I’m on) + Brembo brake pads which also are not stock
based on my experience I'd like to see Randy do 4 back to back runs - don't think the car could do it.
also I'd love to see the MotorTrend battery consumption metrics for the runs - doubt the car could run all day

Top speed in a quick review of the video 109 mph
Max g’s 1.2 g’s in various corners
Handling is stellar
Track mode is a hoot and the car behaves wonderfully
Instant torque off an apex is intoxicating - it’s a thing of beauty - you really really have to try it!

Overall impressions:
The Model 3 handles well and power is ample - at no time did the car’s behavior concern me - handling is stellar for a 38xx lbs 4 door sedan - easy to place on track - this car is really really excellent - just wow!
My overall impression is that the Model 3 is a quick and fun car on track (at laguna) with no stamina what so ever {sigh}. I encountered a few issues with the car in it stock configuration.
Track mode represents a major win and is major progress towards a street EV being a decent track car, but still has a long ways to go. In particular for my circumstance I encountered the following difficulties
- The performance brakes would overheat going in turn 2 by lap #3 or #4 - this was accompanied by a pedal feel loss and greater effort/distance for stopping - it was manageable but disconcerting - confidence post this point on track was low and a wise driver will take a few 10th off the table because now you have to feel out what the car can do rather than just blindly slamming the brakes as the last sec in your braking zone
- The car will still reduce maximum power under battery overheat conditions, but it takes 3 or more laps to encounter this condition - reduction is very very subtle, and it’s just “muted” coming off an apex, or slightly slower uphill or on the straight, nothing overt, but really it’s just not quite as crisp as it used to be…but still mostly fun - you could stay out and still have fun, but see item #1 the brakes have robbed you of your confidence…good thing the car is a bit slower.
- After lap #3 or #4 the car’s performance off the apex of corners going to full power was muted, I could not tell if this was stability control or power limiting due to battery thermals
- Stablity control in track mode is looser, slight drifting is possible, going to full throttle is easy, fun and nearly consequence free, super fun bits of oversteer for that out of corner rotation we all love - if you haven’t experience EV stability/traction control it’s nothing like an ICE, it’s just a very very subtle assist and very non-invasive - very very hard to detect - and again a thing of beauty - I look forward to the future.
- Battery consumption was extreme even with my short sessions (5 laps or less) consuming 30% or more battery - charging infrastructure on site at Laguna is insufficient to sustain the car for a typical 5 session HDPE day (or any track that I'm currently aware of)
- I was never willing to complete more than 5 or 6 laps and brought the car in early in all sessions cause I just didn’t want to flog the car in it’s over heated condition - see above items - I could have stayed out, but why? Why?
- I could drive this car all day even with the power reductions cause it's just a joy to drive, but the brakes and consumption make it a difficult car to track. But the car is still fun even when down on power…handling is just sooooo good.
The summary is really really easy - there is _NOTHING_ wrong with this car’s dynamics, but it has no stamina. I was unwilling to complete a full 25 minute HOD session in C group (advanced point by passing) due to the following issues -
- After the brake warning comes up the 1st time, the braking becomes haphazard and for safety sake I started driving more cautiously
- After lap 3 or 4 laps the car is definitely down on power and becomes a muted version of itself - still fun but no longer super quick
- 5 laps at laguna is 30% or more battery consumption, even if issues 1 and 2 didn’t exist the consumption for a full 25 minute session is untested by me, but I just couldn’t do it knowing I had to manage enough battery for the rest of the day
But the trifecta of:
- Overheated brakes
- Power throttling
- Extreme consumption
The car is really really really good for the 1st 3 laps - nothing to complain about - you might be able to recover it and do another 2 laps if you did a 3/10th pace after the 3rd lap - go out do 3 hot laps, do one full 3/10th lap - go do another full pace 2 hot laps? I didn’t try that. But even so I was consuming more than 30% battery for the 5 laps I was doing, staying out another 3-5 laps would consume another 30% battery? I'll never know.
There is a supercharger less than 8 miles from Laguna - you need 8% battery to get there…so a visit over lunch break would easily get you back to 70-80% battery and come back for the afternoon sessions
I gave up on the afternoon sessions because I felt I had learned all I needed to learn from this little experiment - and didn’t really want to flog the car un-necessarily…
Charging choices at Laguna
- Various NEMA 6-30 plugs in the garages for tire warmers - you need a custom adapter (which I have)
- You have to set the charge rate in car to 24 amps (80% rule) - estimated battery % recovery during 45 min between sessions 6% battery if you’re late to grid and really push it
- There is one available NEAM 14-50 plug next the gas pumps - I was able to recovery 8-10% between session at this one plug
- Leave home at 100% - leave 1 hour early to hit the supercharger at Seaside Tesla (8 miles from Laguna)
- Arrive Seaside Supercharger @ 88% battery - 6 am
- Walk to McDonalds grab some breakfast - watch the charging from the phone app - eat a leisurely breakfast - no hurry
- Unplug from Seaside Supercharger @ 97% - 6:32 am
- Arrive at Laguna and park in paddock/garage - battery is now 90% - 7:15’ish am - unpack set up car and fuss until track goes hot at 9 am
- Plug into garage NEMA 6-30
- Session #1 - enter track with 94% battery - do 5 to 6 laps (data lost due to goPro sucking) - leave track slightly early - 61% battery - consumption 33% for a 2/3rd’s session
- Plug-in to sole NEMA 14-50 next to gas pumps
- Session #2 - enter track with 68% battery - do 4 to 5 laps (data lost due to goPro sucking) - leave track mid point during session @ 37% battery
- begin considering if you’re going to hit the supercharger over lunch so you can do the 2 afternoon sessions
- Realize the good cork screw pictures are session 3 - so decide to tough it out
- Plug into the NEMA 14-50 plug to charge car
- Wait until last possible minute to enter track for Session #3
- Enter track with 50% battery - exit track 4 laps later @ 21% battery
- I decided I didn’t need to flog the car for the after noon sessions - with the long lunch (2 hours) I think I could’ve gotten enough to do the last two session
- But as I said I felt I had learned enough and I have a dedicated track car, this car does not need to be it…

Thoughts/conclusions/observations in no particular order
- The car is really really really good for those 1st 3 laps, truly spectacular given it’s weight and sedan’ness - it was a 100% hoot and I highly recommend it - so easy and quick - really really good.
- Track mode is major progress and this car is way more capable on track than the Model S or X - kudos to Tesla for doing this
- My model S couldn’t even do a full lap without power throttling due to battery thermals, and it’s brakes are just a joke for track use…stamina is even worse.
- If you want to track this car it will need a brake upgrade - the braking inconsistencies mid session really rob confidence and invite an “off” if you don’t adjust your driving - after they overheat it becomes a cautious guessing game as to how hard you want to push the car
- It’s still a bit soft, some stiffer springs would make this car even better (I’ll post pics when I get them, some great compression shots in turn 3 & 4)
- Instant torque on a race track is the holy grail and truly awesome - out future is bright and we'll all love it - it's just sooooo good.
- Brakes can be fixed, the battery thermals can be fixed, you can’t fix the consumption - to truly track this car for a full HPDE day and run full sessions you will need the following
- Fix the brakes
- Fix the battery cooling
- You’ll need some fast DC charging at the track, the Model 3’s 48 amp max L2 charge rate just isn’t going to cut it for a full 5 or 6 25 minute session track day
- You might be able to get away with 72 amp L2 charging like the S/X max charging L2 rate, but the track would need 90 amp L2 chargers - easily achieved, but they would need to be installed
- Anyone claiming a lap record in this car, please ask them if they can do it 4 or 6 times back to back to back - I don’t see how that’s possible with the current production car, but I could be wrong - I often do 6 or 10 laps with in 1/10th of each other in my GT3 back to back to back
- until someone shows me any EV lap time "records" are a one and done affair - you can bank on it!
- You begin the session passing 911’s GTS’s - you finish the session down on power unable to overtake a hot-hatch going uphill between 6 & 7…and staring at the battery % meter and say "wow" - just "wow".
- The car was a thrill really really good, but a disappointment in the end cause I don’t see how you can run this all day at near 8 or 9/10th for 25 minutes at a time…I just don’t think it possible - I could be wrong.
- Off track this car’s range is impressive - 21% battery - getting home from Laguna to San Jose - no problem - put on autopilot have a stress free easy drive home, stop briefly at the Gilroy supercharger - grab an in/out burger, have more charge than you know what to do with in the time it takes to eat the burger - really really back in this car’s wheel house, street driving it’s masterful and really really good car.
- You need 40-50 kWh for a full 25 minute HPDE session - 53% of a Model 3 battery to run a full 25 minute session by my estimates - probably closer to 60%
- Then you need to restore those 40-50 kWh in less than an hour between sessions…let’s say 45 minutes
- 40-50 kWh in 45 minutes is: 70,000 watts for 45 minutes = 50 kWh restored to the battery in 45 minutes
- You need a Fast DC charger at the track - maximum L2 charge rate is 19,200 watts (100 amp circuit and car that can handle it - 80 amp charge rate)
- That’s 1/3 of what you need for a 25 minute DE session @ laguna
I’m impressed
I’m thrilled
I’m disappointed
I’m frustrated
I'm confused

Thank you for the thorough review. It’s great to hear about the excellent handling and the feeling of the instant torque out of the corners, and like you state, brakes can always be upgraded and need to be on many ICE cars when tracked.
But a car, any car, that can only perform 3.5 laps of LS (which means around 7 minutes of run time?), is a total fail for a track car. Plus, assuming the brakes and power reduction issues can be overcome, how is it useful when essentially your whole battery charge is exhausted in one run session?
A great car in in so many ways, but for road course work, it’s not ready and perhaps won’t ever be until battery tech changes.

here is the apex pro lap times for the 3rd session - 4 laps (50% - 21% battery w/overheated brakes)

Fantastic report! Thank you for sharing. It would be fun to read the reactions if you posted over on TMC, in the "Model 3: Driving Dynamics" forum.
IMHO, we won't be seeing more than 48 amp AC charging in the Model 3 any time soon. Unlike the S and X, the charger is embedded inside the battery pack - making real estate for a larger charger difficult. But you are right - best would be some on-site DC fast charging. Interestingly, the Euro Model 3 is going to be equipped with built-in CCS fast charging, with an announced CCS adapter for Euro S/X. I'm guessing that means we could see a CCS adapter here in the U.S. reasonably soon. Once done, some CCS chargers at the track would be a Good Thing. (Obviously a couple of Tesla Supercharger stalls would be best, but I'd assume the track would want a more manufacturer neutral resource.)
Are you using the Tesla 10-30 adapter? It should automatically set 24 amps.

I've given up on the Tesla forums - they can't handle any truth that is remotely critical…don't want to wade through the hater postings to find morsels of truth...quite frankly I'd rather Porsche see this review - I'll expect more for the Taycan - and it will probably be twice the price of the Model 3 - a similar review for the Taycan would be a failure in my opinion - I'll spot Porsche (any EV) the consumption issue and note the tracks are going to need infrastructure (CSS chargers seems to be the path forward).
I'll allow the following:
1. limited but not extreme power limiting - improving over future generations
2. rock solid brakes for at least a 25 minute DE session
3. consumption to be addressed by track infrastructure - fast chargers…
I like you guys!! Even ground hog who thinks I should drive a smaller car.
we will see if the Taycan fairs any better when it's available to drive, but there is a high bar for handling with the Model 3 - but I'm confident Porsche has that one covered. I'm more concerned Porsche is chasing Model S rather than the more current Model 3…

I shared my review with some people that I know associated with Tesla - they are disappointed in my review - but do not dispute my findings.
they have also shared the following
1. Randy Pobst only gets 1 or 2 laps to set his times - 3 at most - there is no "duration" characteristic to any of their reviews
2. they claim most street cars will degrade in a similar if not more spectacular fashion to my experience with the Model 3
3. they called out the Alfa Romeo Quadrifoglio - as having worse degradation than the Model 3 - their test drive only go one lap before the brakes "gave up 100%" at Laguna
they are apparently aware of my critique, and nothing here is news to them - I've instructed some of them in past events and they are aware of my bonafides as an advance track amateur…but yeah the Model 3 is no track car.

my bad - it's not a 10-30 - it's very very strange plug - NEMA 6-30 plug - I built a NEMA 6-30 to NEMA 14-50 specially for Laguna - and labeled it 24 amps ONLY...I haven't checked recently but Tesla didn't have a 6-30 adapter when I was making the adapter for my first visit to Laguna - to be fair I never intended to use the plug to support a track event, rather just charge my EV at laguna while driving my track car…
A 6-30 isn't that rare. I think welders use them. Tesla offered 6-30 and L14-30 adapters for the Roadsters charging kit. But I guess they weren't very popular as Tesla has never made either of them for either gen UMC. Just the 10-30 and 14-30 - which of course are very commonly used in homes for clothes dryers. I wish they did make an official 6-30 adapter for the UMC, because for various reasons I'm probably going to make a 6-30 adapter cable myself soon.

Wow, great review!
Now you know why Formula E switches cars. Which I understand is changing either 2019 or 2020.
It will be interesting to see if the Taycan can overcome the Tesla's shortcomings. Can't wait to see. Suspect the brakes will not be an issue for the Porsche, nor will the electronics thermals. But duration will remain an issue in all likelihood.
Be interested in seeing what happens when you bring it back to the autocross.
A thought: does the M3 performance have brake ducting? Sounds like that might help. Maybe some high quality fluid and track specific pads along with some AX tires will allow it to be competitive? That's it's real bread and butter.

There are lots of Nema 14-50 plugs at Laguna in the camp grounds - but they are not near the paddock - I think you’d lose more driving to/from the camp grounds than you could gain in the time charging - to date I’ve only seen the one 14-50 near the gas pumps - there might be more but they are well hidden.

I have data - the "record" lap was set with the following significant modifications - I did a 1:50 fully stock vs. 1:46.xx on 255 mm (vs 235 street tires) hoosiers and hawk racing pads - I'll throw down my 1:50 as damm quick
Tesla Model 3 with small mods sets new record at Laguna race track
In order to get that time, Rogers had to perform some small yet quite smart modifications that help shave a few seconds. The last time we saw a Model 3 make a hot lap on the race track, the driver was quite surprised by the performance, but he did complain about the brakes.
Rogers addressed the issue by adding Hawk Performance Blue 9012 Racing Brake Pads to his Model 3 and using racing brake fluid. He also used A7 – SIZE: P255/35ZR18 Hoosier racing tires on 18×9.5 Enkei RAIJIN wheels Finally, Rogers also found a way to disable stability control and ABS by unplugging the speed sensors on the wheels.

Thanks for your report Dave. What we need is a head to head between the 340i x-drive, C43, CTS, S4 and maybe throw a WRX or something in there just to mix it up. We could see how they stack up - stock cars straight off the dealer lot on the same day same track same driver. I suspect they all would indeed degrade within a few laps. The Taycan? I can’t wait to find out! The batteries will likely behave the same but with a bit more range given 95kwh rating vs what, like 75 kWh in the M3P? Wouldn’t it be a blast if Tesla offered a Model 3 with a 100kwh battery? It would sweep the streets!

It will be interesting to see what the Taycans energy consumption is compared to its peers. For example the Jag I-Pace reportedly uses a lot more power than the Model 3 (or even the S/X) - just doing street duty. So it needs the extra battery capacity, with associated extra cost, weight, and charging times to offer comparable range as the Teslas.
are a factor, but most all LI batteries will have similar internal resistances. The Porsche EV will benefit from using a 800 volt system, which will help reduce the (I^2 x R) losses
of the battery and reduce charging times.
