Tesla pulled the covers off an all-new roadster that it claims is the quickest accelerating car to have made production yet.
The surprise reveal took place alongside the truck's world debut, where CEO Elon Musk said the open-top model could accelerate from zero to 60mph in 1.9sec.

Musk said the successor to Tesla's first production car can sprint from zero to 100 mph in 4.2 seconds and complete a quarter mile sprint in 8.9 seconds.
"This will the first time that any production car has broken 9 seconds in the quarter mile," he said.
It is also claimed that the Roadster, which has a removable lid and wraparound rear section to give it a look similar to the Mazda MX-5 RF, will have a top speed of more than 250mph.

Musk revealed that the car's 200kWh battery pack enables it to have a 620-mile range, which is another new record for production electric vehicles.
"The point of doing this is to give a hardcore smackdown to gasoline cars," continued Musk. "Driving a gasoline sports car is going to feel like a steam engine with a side of quiche."
The Tesla Roadster is pegged to enter production in 2020, priced from $200,000, which is £151,020 at today's exchange rate.
