Tesla unveiled its second-generation Roadster sports car on Thursday by having the vehicle launch itself up a curved ramp into a controlled landing. It later leapt over five other Tesla vehicles while twisting in the air. The car is scheduled to enter production in 2028. Tesla has yet to release a price tag. The Roadster can go from a stop to 60 miles an hour in about one second, and it has a top speed of over 230 miles an hour.
