Tesla Motors only reveals its production figures every quarter, but it has now likely built about 50,000 of its all-electric Model S luxury sport sedan.
The company also doesn’t group its changes and updates into model years, but makes running changes in the cars whenever the updates are tested, validated, and ready to roll.
Are you a smart car buyer? Take the quiz.
So how is a Tesla Model S built in May 2014 different from the first one sold to a paying customer (actually a Tesla board member) in June 2012?
The shape is still the same; there are still two battery-size options of 60 and 85 kilowatt-hours (a 40-kWh model was dropped due to lack of interest); and there’s a new Performance Plus option at the top of the range.
