Well, a lot more Model Y news today that any of us where probably expecting. Though no unveiling date. • Model Y is NOT going to be built on the same platform as the Model 3, a new platform with reduced wiring • production start optimistically later 2019 or more likely 2020 • Model Y production line will be next generation, more efficient and automated than Model 3. ...and here's Electrek's article on the news- Tesla Model Y: Elon Musk says electric crossover coming in ‘late 2019 or 2020’ on new platform Who knows what motivated the change to a new platform- but that unquestionably played a part in the new rollout schedule. But the new production line may mean the production ramp happens faster- so maybe it will kind of balance out. Still hoping for a April or at the latest Fall 2018 reveal.
