How legacy carmakers fell behind Tesla and Chinese EV brands in software, as a Toyota Woven engineer says the company's new Arene platform is “full of bugs”
Financial Times : X: @scobleizer X: Robert Scoble / @scobleizer : @Techmeme I had a front row seat on how they fell behind. Mercedes Benz had everything Tesla had. Its executives killed everything due to “too much risk.” And other reasons.
Context & Ripple Effects
Software trouble has been a recurring obstacle for established automakers: Volkswagen's ID.3 problems prompted a reboot of its software business, while its subsequent software push was reported to be constrained by internal battles and technical glitches.
Toyota's software effort had already faced organizational friction, with Woven struggling to align with its parent's changing goals in earlier coverage of the unit. By contrast, Tesla's software capability was shown to have operational value when it adapted vehicle software for alternative chips during the chip shortage.
First-order effects
- Arene's reported bugs put immediate pressure on Toyota Woven to stabilize the platform and on Toyota to demonstrate that its software program can support its vehicle strategy.
- The account sharpens the competitive contrast for Tesla and Chinese EV brands, whose software capability is presented as a differentiator against legacy manufacturers.
Second-order effects
- Other legacy carmakers face renewed pressure to shorten decision cycles and resolve the organizational barriers that previously delayed software projects, rather than treating software as a separate support function.
- Software reliability becomes a more visible basis for comparing EV makers, raising the cost of delayed or fragmented platform development for incumbents.
Third-order effects
- If these execution gaps persist, automotive competition may increasingly hinge on the ability to build, integrate, and maintain vehicle software—not only on traditional vehicle engineering.
- The pattern suggests a durable talent-and-organization moat for software-led manufacturers, though legacy groups can narrow it if platform efforts become more integrated and reliable.
The trend: The EV market is shifting from a hardware-centered contest toward one in which software execution and organizational speed determine competitive position.
