Tesla CEO Elon Musk posted two photos of the much-anticipated Tesla Model 3 vehicle to Twitter late on Saturday.

Musk has said that the first 30 Model 3 customers will receive their cars at a party on the 28th. Production is expected to grow to 100 cars in August, more than 1,500 by September, and then 20,000 by December.

Tesla also said current-quarter deliveries would include about 3,500 vehicles that were in transit to customers at the end of the second quarter.

The company said earlier this week it delivered about 47,100 electric sedans and SUVs in the first half of 2017.

Tesla had then not provided details on the number of vehicles in transit.

The company, which blamed "severe shortfall" of new battery packs that constrained vehicle manufacturing until June, reiterated on Friday that combined deliveries of Model S and Model X in the second half of 2017 will likely exceed deliveries in the first half.
