Let me give you a quick flashback, Tesla unveiled its first electric Semi Truck and Roadster fastest sports vehicle.
The $200,000 (£151,000) sports auto - an updated version of Tesla's first production vehicle - can seat four and travel 620 miles (1000 km) on a single charge, a new record for an electric vehicle.

The business tycoon has also divulged that Falcon 9's more powerful sibling will carry his personal midnight cherry Tesla Roadster to space. "Destination is Mars orbit".
Musk expects his Roadster to remain in deep space for a billion of years, unless Falcon Heavy blows up on its way to the red planet.

Falcon Heavy is, in overly simple terms, three of the company's Falcon 9 rockets strapped together.
