Tesla says the Model 3 is the next logical step of its "secret master plan" and mission to accelerate the world’s transition to sustainable energy.
The Model 3 has been engineered to combine range, performance, safety and utility. Interior space should provide room for five adults plus luggage.
A high efficiency electric motor provides zero to 60 mph acceleration in less than six seconds while electric all-wheel drive will be availale as an option.
A range of more than 200 miles is promised, with a starting price of £35,000 before incentives.
Model 3 production began in 2017. Due to delays in production, right-hand-drive versions aren't expected until early 2019.
