Tesla

Tesla Motors founded in San Carlos, California by Martin Eberhard and Marc Tarpenning to build an electric sports car using lithium-ion cells; Elon Musk leads $7.5M Series A in Feb 2004 and joins as chairman.

Original Roadster begins customer deliveries: the first highway-legal serial-production EV using lithium-ion cells, with 245-mile range and 3.7s 0-60. About 2,450 units sold through 2012; proves modern li-ion EVs are viable.

IPO on NASDAQ at $17/share raising $226M: the first U.S. automaker IPO since Ford in 1956. Funds NUMMI Fremont plant acquisition from Toyota for $42M, giving Tesla a 5.5M sq ft factory and seeding the Toyota partnership.

Model S enters production at Fremont; first deliveries on June 22 mark Tesla's transition from niche to mainstream. The 85 kWh sedan with 265-mile EPA range wins Motor Trend Car of the Year 2013 and rewires industry expectations for EV range.

Tesla open-sources its EV patents in 'All Our Patent Are Belong To You' blog post, framing the move as growing the EV market rather than blocking competitors. Musk later credits this with accelerating Chinese EV adoption.

Model X SUV deliveries begin with falcon-wing doors after multiple delays: Tesla's first SUV and a key proof point for Tesla's ability to engineer complex new vehicle architectures, though early units suffer quality issues.

Tesla acquires SolarCity for $2.6B in stock: Musk-led vertical integration of solar + storage + EV; the deal is later upheld in 2022 Delaware court ruling but generates years of governance scrutiny.

Model 3 begins production at Fremont as Tesla's mass-market $35K sedan. 'Production hell' delays stretch the standard-range ramp into 2019, but the Model 3 becomes the world's best-selling EV and crosses 1M cumulative deliveries by Jun 2021.

Reaches Model 3 production rate of 5,000/week after 'production hell': a critical solvency milestone. Tesla pitches a tent line at Fremont (GA4) to hit the rate, the unconventional move that defines Musk's manufacturing approach.

Gigafactory Shanghai delivers first Model 3s less than a year after groundbreaking: Tesla's first plant outside the U.S. and the first wholly foreign-owned automaker plant in China, achieved through unprecedented government support.

Model Y begins production at Fremont; deliveries start in March. The crossover variant of Model 3 becomes Tesla's volume backbone and goes on to be the world's best-selling vehicle (any powertrain) in 2023.

Tesla market cap surpasses Toyota's at ~$210B, making Tesla the world's most valuable automaker just 10 years after IPO and reframing how investors value EV-only OEMs versus legacy ICE makers.

Gigafactory Berlin-Brandenburg opens, Tesla's first European plant, with Musk personally handing over the first Model Ys at a launch event. Initial capacity 250K vehicles/year, scaling toward 500K to anchor Tesla's European footprint.

Gigafactory Texas opens in Austin and becomes Tesla's HQ, housing Cybertruck production and 4680-cell production. The 10M sq ft footprint is among the largest auto factories in the U.S.

First Cybertruck customer deliveries on Nov 30 at Giga Texas: four years after the 2019 reveal. Steel exoskeleton design and 48V architecture make it Tesla's most engineering-radical vehicle, but slow ramp and recalls dog the launch.

Tesla 4680 cell production crosses 100M cells with 4680 cost-per-kWh becoming Tesla's lowest in-house chemistry by Q4: a vindication of the in-house cell strategy unveiled at 2020 Battery Day after years of yield struggles.

Cybercab two-seat robotaxi unveiled at 'We, Robot' event in Burbank: no steering wheel or pedals, target sub-$30K, planned production 2026. Tesla's biggest bet on autonomy revenue replacing per-vehicle revenue.

Refreshed Model Y 'Juniper' begins production in Shanghai with deliveries starting Feb in China; the mid-cycle refresh brings front and rear styling updates, improved range, and quieter cabin to address growing Chinese competition.

Gigafactory Shanghai produces its 4 millionth vehicle: cementing Shanghai as Tesla's largest factory and dominant export hub for European and Asia-Pacific markets.

Tesla Motors incorporated July 2003 by Martin Eberhard and Marc Tarpenning. Elon Musk led the Series A in Feb 2004 with $6.5M and became chairman. The 'car as software platform' thesis would later make Tesla the first automaker to push autonomy via OTA updates.

Hardware 1 (HW1) introduced on Model S vehicles built after Sept 2014: Mobileye EyeQ3 chip, single forward camera, forward radar, ultrasonics. Musk announced 'Autopilot' branding at Oct 9 2014 'D' event (dual-motor reveal); software activation came a year later.

Autopilot V1 software activated via OTA (Tesla version 7.0): Traffic-Aware Cruise Control + Autosteer on HW1. First mass-market consumer car with hands-on highway autonomy. Within weeks customers posted YouTube videos of crashes from misuse.

First fatal Autopilot crash: Joshua Brown's Model S struck a tractor-trailer crossing US 27 in Williston FL May 7 2016: system failed to identify white trailer against bright sky. NHTSA investigation cleared Autopilot of defect; relationship with Mobileye fractured immediately.

HW2 (Hardware 2.0) launched with NVIDIA Drive PX 2 + 8 cameras + 12 ultrasonics + 1 radar. Musk claimed all cars from this point have 'full self-driving hardware': a claim that became the basis of multiple class-action lawsuits 8 years later.

HW2.5 deployed (after Mobileye breakup): minor compute upgrade to bridge to HW3. Tesla began building dedicated Autopilot/AI team; hired Andrej Karpathy from OpenAI as Director of AI June 2017.

HW3 (FSD Computer / Autopilot Hardware 3) launched: first fully in-house autonomous driving chip designed by Pete Bannon's silicon team; 144 TOPS, 7x compute over HW2. Musk claimed at Autonomy Day this hardware would enable robotaxis 'next year'.

FSD Beta limited release Oct 2020 to ~1,000 early-access customers: first city-streets autonomy for Tesla. Vision-based stack on HW3; required driver supervision. Public release of FSD Beta would gradually widen over the next 2 years.

FSD Beta v9 released with vision-only Tesla Vision stack: radar removed from production Model 3/Y starting May 2021. Most aggressive sensor-stack reduction in the industry; Mobileye and competitors retained radar+lidar.

FSD Beta opened to all FSD-purchased customers in North America (~400K cars): removed safety-score gating. Largest single ADAS fleet expansion in history; brought Tesla's supervised-FSD miles into multi-billion territory by 2024.

HW4 (AI4) starts shipping in refreshed Model S and Model Y: 5x compute over HW3. New cameras (5MP vs 1.2MP), updated FSD Computer with Tesla-designed Dojo-derived silicon. Created the HW3/HW4 schism that would lead to 2025 lawsuits.

FSD Beta v11 released: 'single stack' merging highway and city code into one unified neural-network-heavier architecture. Cleared a 6-month delay; precursor to v12 end-to-end.

FSD v12 released: first end-to-end neural network replacing 300K+ lines of hand-coded C++ rules with ~3M video clips. Musk called it 'the most fundamental change'. Raised the bar for end-to-end imitation learning across the industry.

Cybercab robotaxi unveiled at 'We, Robot' event Oct 10 2024 in Burbank: no steering wheel or pedals, target $30K, target production 'before 2027'. Stock dropped 9% next day on muted reception. First Cybercab rolled off Giga Texas line Feb 2026.

FSD Supervised launched in China: first non-domestic L2+ city driving deployment for Tesla. Initially restricted by Chinese data-privacy rules; rolled out via OTA after Tesla agreed to localize map/training data.

FSD v13 rolled out to HW4 vehicles with restored speed-limit and unprotected-turn handling: introduced 'Temporal Intelligence' video buffer (15-sec) for processing video clips vs single frames. Considered first true 'hands-off attentive' grade FSD.

Robotaxi service launched in Austin June 22 2025 with safety drivers in passenger seat: initial fleet ~10 Model Ys. Heavily geofenced, manually monitored remotely. First Tesla 'commercial' robotaxi attempt.

SF Bay Area Robotaxi launches with safety drivers (CA law requires): second Tesla robotaxi city after Austin. Tesla bet that 'cheap fleet of millions' beat Waymo's 'expensive fleet of thousands'.

FSD v14 launched on HW4: '10x larger neural network', described by Musk as 'second-most-important AI/Autopilot update since v12'. End-to-end vision-only stack with new world-model architecture. Began rolling 14.1, 14.2 versions through Q1 2026.

First Cybercab rolled off Giga Texas line; volume production targeted April 2026: initial run hand-built; HW5 (AI5) chip production debut. Cybercab supplier base required ramp through Q2.

Unsupervised Robotaxi launches in Dallas + Houston: Tesla's first 'no in-vehicle safety driver' commercial robotaxi service (remote teleoperators monitor). HW4 + FSD v14.2; geofenced ~50 sq mi each city.

Tesla facing up to $14.5B in cumulative class-action lawsuits across US (HW3 fraud), Europe (5,700+ HW3 claimants from 37 countries), Australia (thousands), and China (1M+ vehicles). 'Hardware Statement' from 2016 Autopilot 2.0 launch became central evidence in shareholder fraud certification (Aug 2025).

Initial stationary-storage product Tesla pilots at SolarCity homes: repurposed Roadster battery packs in residential applications, the proof-of-concept for what would become Powerwall. Anticipates a separate-business storage opportunity 5 years before formal Tesla Energy launch.

Powerwall 1 (10 kWh, then 6.4 kWh DC-coupled by 2016) and Powerpack (100 kWh) launched at Hawthorne, California event by Elon Musk on Apr 30 2015: formal birth of Tesla Energy as a distinct business unit. Powerwall list price $3,000 / $3,500; Powerpack $25,000. Demand vastly outstripped supply: pre-orders booked through 2016 within first week.

Powerwall 2 unveiled: 14 kWh usable, integrated 5 kW inverter, AC-coupled architecture, $5,500 starting price (vs $3,500 PW1 + inverter). 2x energy density at lower $/kWh. Drives 5x demand uplift versus PW1; backlog crosses 500k pre-orders by 2018.

Hornsdale Power Reserve in South Australia (100 MW / 129 MWh) energised: world's largest Li-ion battery at the time, deployed in Elon Musk's famous "100 days or it's free" public bet with Mike Cannon-Brookes. Cycled within first weeks to stabilise national grid frequency events; saved AEMO ~A$150M in FCAS costs in first 24 months. The most influential utility-scale battery project ever: proves grid-storage market viability and unlocks subsequent multi-GWh project pipeline.

Megapack utility-scale product launched: 3 MWh per unit (later expanded to 3.9 MWh with XL variant) with integrated inverter and thermal management. Pre-engineered, factory-assembled approach drastically reduces deployment timelines from 12-18 months to 3-6 months. Drives Tesla Energy revenue inflection: $1.5B 2019 to $10B+ run rate by 2024.

Battery Day at Fremont: 4680 cell architecture announced with tabless ("shingle spiral") design, dry-electrode coating, silicon anode roadmap. Promised: 5x energy/cell, 6x power, 16% range improvement, 14% $/kWh reduction. Format becomes industry-defining target for 2022-2025; LG, Panasonic, Samsung SDI, EVE Energy, and BAK all spin up 4680 lines in response. Tesla 4680 ramp itself slower than promised: only ~30% of Model Y mix by end of 2024.

First 4680 cell production line ramped at Kato Road pilot facility, California: 100 cells/day initial output expanding to 1,000/day by end of Q1. Cells installed in Model Y vehicles produced at Texas Gigafactory; deliveries begin April 2022. Dry-electrode cathode coating remains the bottleneck for full ramp through 2024.

Inflation Reduction Act signed Aug 16 2022: Megapack and 4680 cell production qualified for 45X manufacturing credits ($35/kWh cell + $10/kWh module). Estimated 2024 Tesla Energy cumulative IRA windfall: ~$2-2.5B; transforms Megapack gross margins from ~10% to >25%.

Lathrop Megafactory opened in California: initial 40 GWh/yr Megapack capacity (10,000 Megapacks/yr). First dedicated stationary-storage gigafactory in the US; supplies Megapack 2 and Megapack XL (3.9 MWh) units globally before Shanghai Megafactory comes online 2025.

Megapack 2 XL announced (3.9 MWh per unit, 30% larger than Megapack 2) and Shanghai Megafactory groundbreaking: 40 GWh/yr capacity for international markets, 10,000 Megapacks/yr. Tesla's first non-US gigafactory dedicated to stationary storage; production starts Feb 2025.

Powerwall 3 launched: 13.5 kWh with integrated solar inverter (11.5 kW continuous) and built-in solar MPPTs. ~30% lower $/kWh installed than PW2 with inverter. Drives 2024 Tesla Energy residential Powerwall deployments to >100k units.

Deployed 31.4 GWh of energy storage in 2024: more than tripled 2022 levels (6.5 GWh) and almost doubled 2023 (14.7 GWh). Tesla Energy reaches ~$10B annualised revenue run-rate at >25% gross margin (with IRA credits). Now Tesla's fastest-growing segment by relative growth.

Shanghai Megafactory began producing Megapacks for international markets: initial 40 GWh/yr ramp, supplying European, Australian, Middle East ESS integrators. Hedges against US-China tariff escalation; Tesla's first non-US storage gigafactory at scale.

Megapack 3 unveiled at Houston event: 5+ MWh per unit, integrated transformer, 50% lower $/kWh installed than Megapack 2 XL. Standardized 20-foot ISO container form factor. Targets 2026 Lathrop and Shanghai production from H2.
