Tesla Model S P100D still king, but Elon Musk dubs Model 3 Performance as ‘higher value for money’
Tesla continues to actively promote the Model 3 to customers, with CEO Elon Musk recently stating that the Model 3 Performance is “higher value for money” compared to the company’s top-tier vehicle — the Model S P100D.
Musk’s latest push for the Model 3 Performance came as a response to a Model S P85D owner, who inquired if it is worth trading in his larger vehicle to the smaller but seemingly more nimble Model 3 Performance. For the first time since the Model 3’s launch, Musk compared the car favorably against the Model S P100D, at least when it comes to value for money.
Model S P100D is def still the top end, but Model 3 Performance is higher value for money
— Elon Musk (@elonmusk) August 5, 2018
In a lot of ways, Elon Musk’s statement does ring true. After all, the difference between a fully loaded Model S P100D and a fully-optioned Model 3 Performance is substantial. In Tesla’s design page, the Model S P100D is listed with an estimated cost of $135,200 with all options included. The Model 3 Performance, on the other hand, costs $80,000 fully-loaded. That’s a difference of roughly $55,000 — just slightly above the cost of a non-performance Tesla Model 3 Dual Motor AWD before any options.
This is not to say that Tesla is dissuading customers from purchasing the Model S P100D, of course. As mentioned by Musk in his tweet, the P100D is still the top end of Tesla’s offerings. With its gut-wrenching 0-60 mph time of 2.28 seconds with Ludicrous Mode, it is far quicker than the Model 3 Performance, which has a 0-60 mph time of 3.5 seconds. Nevertheless, the Model S P100D is known for severely throttling its performance when driven hard around the track — an issue that is not present in the Model 3 Performance, thanks to a clever battery and electric motor cooling system. The Model 3’s electric motors and battery use cooling circuits that are independent but linked. In the event that one component heats up, the system shifts cooling capacity where it’s needed. The system can also use the battery as a heat sink to shed excess thermal load from the motors.
Elon Musk’s latest tweet about the Model 3 Performance says a lot about the company’s strategy in the coming quarters. In the recently-held Q2 2018 earnings call, Musk and Tesla’s executives stood firm on their target of making the company profitable in the third quarter. Musk mentioned this in the call, when he linked the company’s profitability target to the Model 3 ramp.
“At a production rate of 7,000 cars a week, we believe we can be sustainably profitable from Q3 onwards. We’re going to try to raise that rate of the Model 3 production steadily in the coming quarters and try to get to the 10,000 cars a week number as soon as we can. I feel comfortable achieving a GAAP income positive and cash flow positive quarter every quarter from here on out,” Musk said.
So why the Model 3 Performance? Tesla likely makes a good amount of profit from the Model S P100D, but the full-sized sedan’s production has pretty much plateaued over the years. The Model 3 ramp, on the other hand, is still ongoing, and is expected to rise significantly in the coming quarters. Tesla is aiming to hit a gross margin of 25% for the Model 3, and with the vehicle’s production estimated to hit 10,000/week sometime next year, Tesla appears to have a solid shot at making its sustained profitability goals a reality.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
