While Tesla has not yet revealed any mechanical specifications for the dual motor Model 3, the range-topping small auto will offer upscaled performance much like the larger Model S and Model X, both of which now only offer dual motor layouts.
Tesla is ramping up production of its all-important small vehicle.
Police said on Monday that the driver, who suffered a broken ankle, said she had been using Autopilot before the crash. Musk also said that Tesla is the safest auto.
Driver: Tesla's Autopilot engaged during Utah crash
Despite an earlier stated target of producing 5,000 Model 3 cars per week, the company was producing a little over 2,000 units per week by mid-April, which led to serious questions on the project's viability.
The brigade reportedly pulled the comment from its Facebook page, later adding that an investigation was underway and declined to comment further.
According to a Reuters report citing sources "inside the company", Tesla is shutting down its Model 3 assembly line for six days, in order to perform upgrades that will help Tesla reach its production goals.
According to the police, the Model S slammed into the firetruck at 60 miles per hour (96 km/h) and the driver suffered a broken right ankle.
Autopilot, a form of advanced cruise control, handles some driving tasks and warns those behind the wheel they are always responsible for the vehicle's safe operation, Tesla has said. "It is not a self-driving system", Musk said. The NTSB had yet to announce whether they will be looking into the Utah crash.
Tesla has since pushed back its 20,000 units/month production goal to the end June of 2018.
Tesla's Autopilot system uses radar, cameras with 360-degree visibility and sensors to detect nearby cars and objects. Police believe speed played a role and that the autopilot function was likely not switched on at the time of the accident.
The NTSB said last week it was investigating a Tesla accident in Fort Lauderdale, Florida, on May 8 that killed two teenagers and injured another - the agency's fourth active probe into crashes of the company's electric vehicles.
