The Model S 70D upgrades the Model S's 60-kilowatt-hour battery to a new 70-kilowatt-hour model. That gives it a top speed of 140mph, 514hp (compared to its predecessor's 380hp), and a 0-60 speed of 5.2 seconds (0.7 seconds faster than the Model S).
That's just shy of the performance of the Porsche 911 Turbo, which costs roughly twice as much.
The Model S 70D also goes 240 miles on a single charge, which is 15 per cent further than the Model S.
A software update is due soon that will let the car drive itself. These updates install themselves over-the-air. It's as simple as updating your phone. Tesla also added three new colours: warm silver, obsidian black and ocean blue.
The new Model S 70D is on sale now, and costs £54,500 including the £5,000 UK Government Plug in Grant. Delivery is expected in one to two months.
