At last night's event, Tesla had another surprise up its sleeve, a revamped Roadster: "A bonus, Tesla also unveiled a refresh of its original Roadster, targeting production in 2020, created to be the fastest production auto ever made with 0-60 mph acceleration in 1.9 seconds and a huge 200kWh battery pack enabling 620 miles of range".
The new Roaster seats four and costs at least $200,000.
Musk didn't give the top speed but said it would be above 250 mph, and added that the 200 kilowatt-hour battery pack would give it a range of 620 miles on a single charge.
Company CEO Elon Musk unveiled the Semi, which is more aerodynamic than the Bugatti Chiron supercar ($2.6M USD), capable of going from 0-60mph with a full 80,000 pound load in 20 seconds.
The young market for electric cargo trucks is mostly focused on medium duty, rather than the heavy big rig market Tesla is after.

For one, it's unclear if Tesla will actually get the Semi rolling out by 2019 as promised. And the truck integrates several components of the Model 3, including the screens, motors and door handles. The question remains whether the company can keep up with demand for its electric vehicles (Model 3 owners are still waiting to get their cars). "People have asked us for a long time, 'When are you going to make a new Roadster?' We are making it now", Musk said. "It probably is, based on the specs provided, but this isn't necessarily a slam dunk".
Remember the original Tesla Roadster - looked a bit like a Lotus Exige, costed a lot more and went like stink?
Hirsch agrees. "The Tesla Semi is not for long haul trucking." he said. Tesla also reportedly is encountering problems with welding and assembly at its Fremont, California production facility.
Mr Musk did not reveal the lorry's price.

"So far, that final element has eluded Tesla Motors, which makes it hard to see these vehicles as more than "what if" concept cars".
Mr Osborne said Tesla's cumulative capex announcements now exceed $15 billion to $20 billion over the next few years. Inside the truck's cabin - tall enough for a driver to stand upright - there are two large touchscreen interfaces. And charging even a mid-sized truck would likely require a two-hour stop, cutting into companies' efficiency and profits, says Brian Irwin, managing director of the North American industrial group for the consulting firm Accenture.
