Musk managed to get the job done, just.

Tesla has built 5000 Model 3s in a week – thanks in part to a hastily-erected tent in the brand's Fremont factory parking lots – marking the completion of an Elon Musk promise.

The strong Model 3 output, combined with good demand for Model S/X, drove second-quarter production to 53,339 vehicles, a new record.

Meeting the goal hasn't been easy for Tesla. Around 20 per cent of the 5000 cars built last week came from the aforementioned tent, although the company is adamant there should be no noticeable drop in quality on those cars.

The New York Times reports the latest batch of Model 3s makes do without 300 of the underbody spot welds used on earlier designs, after engineers deemed them an unnecessary waste of time.

That same report also said Tesla will occasionally pull its machines off the production line and crank them beyond manufacturer specifications, just to see how fast they can run. Automation has been at the core of the brand's issues, with Elon Musk admitting he relied too heavily on robots early in the piece.

Now it's managed to crack 5000 cars per week, Tesla is planning to bump that figure up to 6000 throughout August. The company says it has 420,000 orders left to fulfil for the Model 3, with right-hand drive production set to kick off in 2019.

Production of the dual-motor and Performance-grade cars started in mid-May, while air suspension will be added to the options list next year. The staggered rollout is designed to minimise complexity on the production line, making it easier for Tesla to meet its founder's goals.
