2003-2025

$TM· Lexus
World's largest automaker by volume, entering the BEV market with the bZ4X crossover and upcoming bZ lineup while maintaining dominance in hybrids. Sold ~170K BEVs globally in 2024, a small fraction of its 10M+ total annual sales but growing rapidly. Investing $35B in electrification through 2030 with plans for next-gen solid-state batteries and a dedicated BEV factory.
Key Milestones
Toyota Motor Co. founded by Kiichiro Toyoda in Aichi Prefecture as a subsidiary of Toyoda Loomworks: develops Toyota Production System (TPS) post-war, becoming the world's largest automaker by 2008.
Prius hybrid launches in Japan: Toyota's pioneering hybrid that delays its BEV pivot for two decades by establishing Toyota's hybrid-electric leadership and proving hybrid can be commercially viable.
RAV4 EV (second-gen) launches in California with Tesla powertrain: production ends in 2014 after limited demand. The Tesla partnership reveals Toyota's reluctance to invest in in-house BEV powertrains.
Mirai fuel cell EV launches in Japan: Toyota's hydrogen alternative to BEVs and the brand's controversial bet that fuel cells will dominate clean mobility, a position that ages poorly versus BEV trajectory.
Reveals 16 BEV concepts and commits $35B/15 BEVs by 2030 in a strategy reset: including Lexus EVs. Akio Toyoda finally publicly capitulates to BEV-first reality after years of resistance.
bZ4X launches in Japan and globally: the first vehicle on Toyota/Subaru's e-TNGA dedicated BEV platform. Long-awaited entrance into BEV mass-market that immediately stumbles on quality issues.
bZ4X recall over wheel-detachment risk forces global stop-sale weeks after launch: embarrassing Toyota's BEV debut and reinforcing perception that Toyota is years behind Tesla and Hyundai/Kia in EV engineering.
Announces solid-state battery breakthrough targeting 1,000 km range and 10-minute charging by 2027-28: Toyota's biggest single technology announcement of the decade and the platform that would catch up to BYD/CATL.
Announces 10 new BEV models by 2026 in updated electrification strategy: Lexus, Toyota, and bZ-brand models on a renewed e-TNGA architecture with revised pack chemistry and digital platform.
Toyota partners with LG Energy Solution for North American EV battery supply at 20+ GWh capacity: first major external cell-supplier deal, reflecting Toyota's recognition that internal cells can't scale alone.
Delays U.S.-built three-row BEV by years; halves 2026 BEV target to ~1M units: citing slower U.S. adoption and aligning with peer-OEM (Ford, GM) strategy resets.
Updated bZ4X launches with faster charging, more power, and longer range: rebranded as bZ in many markets; Toyota's first major BEV refresh signals readiness for sustained BEV competition.
Toyota announces partnership with CATL for next-gen LFP and sodium-ion cell supply for Chinese BEV models: final acknowledgment that Toyota's in-house cell timeline cannot match China's pace.
