Elon Musk gives tips to optimize Tesla Model 3 Performance, teases 0-60 mph in 3.3 seconds
Elon Musk recently gave some tips for would-be owners of the Model 3 Performance — in order to fully optimize the electric car’s capabilities and speed, equipping it with stickier and wider tires at the rear is recommended. According to Musk, the Model 3 Performance would likely be capable of sprinting from 0-60 mph in 3.3 seconds with optimized rims and tires.
Musk’s advice came as a response to Tesla enthusiast Ryan McCaffrey, who mentioned an observation from the Wall Street Journal‘s Dan Neil, who recently reviewed the Model 3 Performance. According to Neil, the Model 3 Performance is already an excellent car, but it would be even better if it had a better set of tires. Musk responded, stating that Tesla had to give up some of the car’s grip to optimize its range. For drivers aiming for top performance, Musk stated that upgrading the tires and wheels can give the car an extra boost.
Definitely. We gave up some grip & width in exchange for range. Would recommend stickier tires & wider on rear for best performance. You might get 3.3 sec 0-60 mph or better with optimized rims & tires.

As could be seen in Tesla’s configuration page for the vehicle, the Model 3 Performance is capable of going from a dead stop to 60 mph in 3.5 seconds, thanks to its twin electric motors that deliver instant torque. The electric car also has a top speed of 155 mph, as well as a range of 310 miles on a single charge. In true Tesla tradition, Elon Musk teased back in May that the Model 3 Performance’s power output could be a bit higher than expected.
Tesla already has a reputation for making its vehicles faster over time. Just last year, Tesla opted to “uncork” the 75D variants of the Model S and Model X. The Model S 75D, for example, had a notable boost in acceleration after the vehicle’s 0-60 mph time was reduced from 5.2 seconds to 4.2 seconds through a free software update. The Model X 75D also had a similar performance bump, with the all-electric SUV’s 0-60 time dropping from 6.0 seconds to 4.9 seconds. Thus, with Elon Musk’s announcement last May, expectations were high that Tesla would likely improve the Model 3 Performance’s acceleration and capabilities over time as well. Talks of a Ludicrous Mode upgrade, which Musk reacted positively to before, were also reiterated.
When he announced the vehicle’s specs on Twitter, Elon Musk stated that the Model 3 Performance, with its 0-60 mph time of 3.5 seconds, would be 15% faster on the track than a BMW M3. Considering that a simple improvement in wheels and tires would likely cause the vehicle to accelerate .20 seconds faster, Musk’s estimates for the Model 3 Performance might actually end up being rather conservative.
When Tesla announced the Model S P85D back in 2014, the company unveiled the vehicle’s Insane Mode, which allowed the family sedan to accelerate from 0-60 mph in 3.2 seconds, rivaling the McLaren F1, a legendary supercar that Musk admits is one of the best cars to ever be made. The McLaren F1 has a 0-60 time of 3.2 seconds — just .10 seconds faster than the raw acceleration of the Model 3 Performance with wider rear tires.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
