Elon Musk announced Sunday that Tesla's launch of a product “unexpected by most” had been pushed to Oct. 19. The launch, earlier scheduled for Oct.17 was moved to Wednesday to work on “refinement” of the highly-anticipated product. While the company has kept the product under wraps, rumors are rife about what it could launch Wednesday. 

The mysterious product reveal is expected to be a part of Musk’s “Master Plan, Part Deux,” revealed in July. His plans included working on sustainable energy as an alternative to fossil fuels, energy generation and storage and major forms of terrestrial transport.

Here are five Tesla products rumored to be launched on Wednesday:

1.  Autopilot 2.0

Tesla launched the first version of its semi-autonomous driving system, Autopilot, in October 2015. The automaker is expected to significantly improve the software and release new features on the same hardware with its Autopilot 2.0 launch. The next generation autopilot is expected to feature a sensor suite, which will potentially enable fully autonomous driving.

Elektrek reported that Autopilot 2.0 would feature a front-facing triple camera system. It is also expected to feature radar sensors with the capability to see through snow, fog and dust, and high precision maps superior to normal navigation maps.

2. Tesla Truck

Musk had revealed Tesla’s plans to launch a pickup truck and a heavy duty one in his “Master Plan, Part Deux.” Tesla plans to cover the major forms of terrestrial transport.

“With the Model 3, a future compact SUV and a new kind of pickup truck, we plan to address most of the consumer market. “ Musk had stated at the time. He further mentioned that Tesla Trucks were in the early stages of development.

3. Model 3

Tesla Model 3 was announced in March 2016. Musk also mentioned at the Code Conference in June that there would be a Model 3 event by 2016-end. It is being touted as Tesla’s electric car for the masses, priced at $35,000.

The 5-seater can travel 215 miles on a single charge and goes from 0-60 in six seconds. It comes with superchargers, which can deliver 170 miles on a 30-minue charge.

4. Ride-sharing service

Musk mentioned in his "Master Plan, Part Deux" that Tesla is working on a fleet of self-driven cars for ride-sharing.

Customers would also be able to add their car to the Tesla shared fleet by tapping a button on the Tesla smartphone app. This technology would generate income for the consumers while they are busy doing something other than driving and lower the cost of ownership for Tesla cars.

5. Home Energy Storage devices

Powerwall 2.0 and Powerpack 2.0 — Tesla’s home energy storage devices might be unveiled Wednesday.

Electrek reported two weeks back that Powerpack 2.0 will be fitted with Tesla’s new “2170” battery cells and would be launched “towards the end of the year.”
