The criteria of the study is horrible. They assume, like most pro-legacy analysis, that Tesla is going to stand still from here on forward while everyone else will leap forward at an unreasonable pace.
Here are their criteria for the score:
- Technology and strategy (model portfolio and technology roadmap) – 30% weighting factor;
- Battery technology (cost position and technology maturity) – 20% weighting factor;
- Culture and incentives (leadership and incentive system) – 10% weighting factor;
- Supplier network (value chain integration) – 15% weighting factor;
- Ecosystem and partners (charging technology and third-party services) – 15% weighting factor;
- Financial performance (EBIT as e-mobility investment indication) – 10% weighting factor.
Absolutely nothing on access to batteries. They track the tech and cost position but zip on how many they can source by 2021. Tesla is the only car manufacturer today who has enough batteries to mass produce EVs and it will likely have the largest supply in 2021 too. Mercedes might be able to make more electric lawn ornaments by 2021 (EVs without batteries), but the problems Hyundai is having with the Ioniq is likely going to hit other car makers going forward. Supply is increasing, but Tesla is way ahead and will likely stay way ahead for a long time to come.
Tesla also has the new Roadster and Semi coming soon and the Model Y may be out by 2021.
This study looks like GIGO (Garbage In Garbage Out).
