The electric vehicle (EV) pioneer's stock is at risk of taking another big hit if Musk and his team don't overdeliver on Q3 results -- or at least earnings call data.

A new design ethos was on full display at the Tesla Robotaxi event, offering some not-so-subtle hints of what to expect from a future sub-$30,000 Tesla.

Along with the robotaxi, Tesla is expected to provide updates on its humanoid Optimus robot — after all the event is titled “We, Robot,” a reference to Isaac Asimov’s seminal work I, Robot . Tesla might also show one of its mystery vehicles — a van or a cheaper car that could compete with China’s growing affordable EV market.

Tesla's stock price hinges on its Robotaxi service, but you can get its biggest competitor practically for free.

Americans bought a record number of electric vehicles in the third quarter. What’s more, EVs accounted for almost 9% of all new-car sales.
