I’ve owned a 9 second street/strip car since 2004. I need to know how to get 40k miles of street driving plus more than 500 passes on the drag strip without having to pull the engine every other season and re ring, new bearings, rebuilding the turbo, replacing head gaskets. I mean, it’s all part of the journey of having a street capable 9 second car but man I’m getting older and I’m about tired of working on it all the time. Basically what I’m saying is if you’ve only lost 1/10 and a few mph and almost never have to do maintenance on it then that’s considered a win. Stop complaining 😂😂

[@Jimster481]

I mean, that is a thing but it depends on what engine and how much power you are making. Getting 40k miles out of an LS that is boosted (as long as its not a moonboosted car) should be more than fine. I don't see why the engine would fail overall.

[@chasejansson7289]

you can see thenew one pulling away though

[@Doctorbasss]

As for technical understanding of WHY trap speed is lower on OLD plaid here is the reason: The battery voltage sag more because of battery age. This translate to lower maximum kW = lower trap speed. The internal resistance of the battery is probably a bit higher after it aged. One way to verify that is to use one of the app that allow you to measure max and min battery voltage and record the minimum battery voltage during one pass and compare results with the NEW plad. You will get the answer.

[@v4skunk739]

The main reason is Tesla limits the cars power after so many launches.

[@vinny9152]

This is the most likely reason. The vehicle keeps track of a variable called “Max Discharge”, which is affected by SOC, health, and temperature of the cells.

[@chachichochacorta8577]

Great content, as always, Brooks. I would say that the old Plaid is still above and beyond quick even with its minimal loss. I wonder how it will perform with 60K miles on it. Too bad those brakes heated up so quickly. About the CCAN Action Fund: I always thought you were more of a Lincoln/Reagan type, not a FDR/JFK type.

[@VuBeClan]

Could be. I'm leaning more to the side of battery or even motor degradation. No piece of equipment is immune to degradation or fatigue over time.

[@vinny9152]

Every Tesla vehicle has a dynamic variable called “Max Discharge”. It’s likely that a worn battery has a slightly higher internal resistance, leading to a reduced peak power which begins to show its effect in the latter half of the drag race.

[@bjornar9026]

I'd think the Tesla will have lost more power. Both because it's an ev, and because of the typically bad engineering by Tesla.

[@abc123fhdi]

if you maintain the gas car, 37k miles is nothing and you can tune it but not much you can do with a Tesla.

[@XennialGuy]

I don't think it's losing 90HP. Probably more like 50Hp up top only. Losing 90HP would be essentially losing almost 9% power. You would be more than a 10th slower and trap would be gapped more if that were the case. A 5% loss is more in line with those numbers.

[@wjrneo2]

Realistically if its a battery issue it will show up in the trap speed and not the launch because the car is so traction limited at launch that up until 60mph+ (maybe even up to 100mph) the car is managing traction by reducing duty cycle on the motors. So a plaid with a worn battery might still launch brutally fast, but once traction is no longer a factor, the battery cannot supply the current needed without a voltage drop, so you lose power (watts) because Volts * Amps = Watts. And when the system is demanding upwards of probably 1900amps from the battery there is a big difference if the voltage drops from say 400v to 385v.

[@patara1234]

​​​@@wjrneo2 use obd,you will see current draw from battery. i consider the modify wheel and tyre not to use factory spec make old car a bit slower at top end. consider every drag on car are very importance to reduce EV car performance at high speed. my English writing is not good sorry.

This is really a loaded question. Battery tech and charging are still relatively new at this scale and Im sure improvements will be better over time. How do you charge? We know you run the car harder than the average consumer so does that play a factor? What are your charging habits, etc., etc? All of these unknowns play a part in answering your question. I also wonder if a software update can resolve the issue? Nice color on that Lucid in the background btw.

[@travisyarbrough4033]

Now Lucid is hammering the Plaid run after run. Doing all out runs is also temp regulated. If you live where it is very hot then the car will go with safety over speed. Some factors but Brooks you would know if you have run all these cars. LOVE THE CHANNEL !!!!! You put em to the test.

[@CRatcliffe]

I would enjoy seeing what it does up here in Colorado. My refresh 22 MS (non plaid) ran a 10.61 so it would be interesting to see with the altitude and air density what the plaid would run.

[@wjrneo2]

Air density has a significantly reduced affect on an EV as it only affects the drag on the car and not the power produced by the motor system. on an ICE car less dense air means less oxygen in the engine, and if the car is NA that means reduced overall output. Even with a forced induction car it reduces power, though with less loss than compared to a NA car.

[@wjrneo2]

I was recently in the market for a C8Z06, I wanted a 1LZ Z07 car with the comp seats, aka stripper with all the perf goodies, but due to the shortages my allocation got pushed WAAAAY back. Not surprised considering I negotiated a MSRP price. So I took my DP back and used it to buy the cheapest Plaid in the area, ended up with a 47K mile car, that I later found out had been used as a Turo car. When I finally got a L2 charger installed at home I did a Battery test and discovered the battery was only at 86% health. My range is not great, but I don't use the car for road trips really, I have 2 toy cars for that, one a Focus RS, and the other heavily modified 89 TransAm GTA. Your trap speeds make me feel a bit better, as when I discovered the battery health was at 86% I was kind of frustrated, thinking about the performance I had lost from not buying a new one. I saved ALOT buying used. So far, I've trapped about 144mph on draggy, but only when the battery is above 85%, under that trap speeds seem to drop, at around 70% I think its around 141mph, and when I get near 50% there is a huge difference in acceleration, I'd say like Sport vs Plaid mode feeling. My bet is that as a Turo rental car, this car was frequently supercharged as the only charge method, and probably kept at at or near 100% so it could be delivered to renters with a full SoC. Which negatively impacted the battery health. That said, I did save over $30k on it as a used car.

[@aussie2uGA]

Yep, it’s proven not to be the supercharging but leaving it constantly above 90% SOC takes its toll.

[@lachlanB323]

@@aussie2uGA That and never charging at home. Charging at home once a week is recommended otherwise it can be detrimental to your battery.

You can recover some of that back. Done that to two Tesla's and a Taycan and had great results. Run the car to under 15% state of charge. Leave it for a minimum of 12 hours uncharged. Then charge with Level 2 to 100% soc. Now test the battery health. You will be back to 90-93% health.

[@ayushmalpeddi2793]

For anyone wondering its down to the battery. The motors are still perfectly capable of producing the 1000hp+ and making the car do 215mph (with speed limiter removed), but the battery will have some degredation. Could also do with Tesla limiting software somehow. Notice this will mainly be seen in the Plaid which is pushing the battery to the limit.

You should do a test where both Plaids have about 40k on them, but one that has been babied rarely do they on the accelerater and one that gets dogged out. I have a feeling there will be a difference in the two.

[@WestCoastSupercarsandClassics]

How does your Dragy compare today with your Plaid when it was new? That would give you the most accurate measure of performance over time. There is definitely a hp difference between the two at this point.

[@DragTimes]

9.2 @ 152 MPH when it was new....

[@markmonroe7330]

A 5mph loss of trap speed is significant. I ran it through a few 1/4 calculators and most show about a 100hp difference with a Plaids weight and a 5mph difference around 145-150mph trap speed. So about a 10% loss of power for the older Plaid. I wonder if this is true for Plaids in general with higher miles/years on them or just your particular car? I wonder where the loss is occurring? the battery? motors? friction some place? are brakes dragging?

[@thegzak]

Is it because of the age and mileage of the old car, or the small tweaks and improvements they’ve made in the newer one since then?

[@user-vp1sc7tt4m]

I wonder if Tesla has any suggestions on the cause of the degradation. Performance reduction caused by inverter, battery, drivetrain component or other?

[@kroven009]

Hopefully they'll have a new version by next year. They seem to do the big changes every 4 years or so. This battery degradation makes me not want a used one because who knows how the previous owner treated it.

[@ZREXER1250]

But with EV depreciation about the same as dropping an anvil off a cliff, a three year old Plaid is half price compared to new and still faster than virtually anything on the road.

[@ryanpetree6475]

It looks like you have aftermarket wheels on it. So are they wider/heavier? That would absolutely make a big difference and explain why you had a better ET even though you had a few mph less.

[@DragTimes]

They are much lighter than stock and the same spec as the Tesla track pack wheels and tires

[@LexRex717]

Wow it really lost a bunch of MPH !

[@stephbarbershop2518]

Doesn't the new one have the new larger cell?

[@Peter_Trevor]

New brakes! Does this now mean it will be written off?

[@TraderJono]

Interesting the new plaid beats the 37k miles plaid with lighter wheels (based on all 3 times). I thought the difference would be less than that

[@sasukesuite1]

My Model 3 has a 60-130 time of around 12 - 14 seconds, so even with the degradation that Plaid is still on another level lol.

[@jrherita]

FWIW - the 2024 Model 3 performance can do 60-130 in 8.62 secs

[@mattnycm3]

If you could run the new Plaid against a lower milage older one to see if the mileage and wear and tear may be the reason your car is slower. I think with anything mechanical, over time performance can diminish... I agree there should be a carbon ceramic brake option.

[@6GZL1]

It depends a lot on the charging habits and typical SOC the car has seen. Was it charged to or near 100% quite often? Supercharged to 100% often? Did it sit at 100% SOC for long periods? When it sits for longer periods, is it kept between 30-50% SOC? The power falloff from 100% down to ~65% is a tenth or less on a fresh battery, so there’s no need to charge the car to 100% a lot for daily use. Hell, it’ll still run 9s at a 20% SOC. Keep it between 50-80% max for daily, just charge to 100% right before you go to an event or something where you’re trying to put up your best possible numbers. When you do charge to 100%, try to time it to complete right before you leave so it’s not constantly recharging it from 98% to 100% over the time leading up to your event. Battery care has a slight learning curve to adapt to in order to keep it near full capacity for as long as possible. If these things were all done, then I’d venture to say that the battery is degrading at a slightly more rapid pace than it should, given that it’s not another problem that is. You may want to do a battery health check through the app to get an idea where it’s sitting. Love the videos. Keep it going!

Regardless, the model S design looks the best out of all the family cars and most practical with the liftback.

Think about what would happen to a 1,000+ HP ICE car if you daily drove it and raced it on the weekend. It wouldn’t even make it to 20k mile much less 30k+ miles. Honestly, that isn’t as much degradation as I thought it would be.

[@johnjackson2349]

The first ICE vehicle was the Veyron to have that kind of power, because of the massive engine and reasonably low state of tune while it may loose a few horses it's nothing compared to this plaid, but yeah cost 10x the price 😂

@@23for82bigs Exactly. I deal with a lot of 4 figure street cars and these guys race (legally and illegally) all the time. Not uncommon to see them go 50k-60k miles on an 1100-1200 hp V8 on E85 before a rebuild. But in the aftermarket you're rolling the dice with who builds it/tunes it/maintains it - and no warranties.

Correct me if I’m wrong but can’t you can pay to get new batteries and motors fitted from tesla after so many miles

Might as well buy 50% of another Plaid if you wanted to replace the batteries and motors.

Very interesting 👍 losing hp after only 37k miles is crazy…

Combustion lose hp too. Usually around 200k miles.
