|By 2017 Elon Musk has promised that Tesla Motors will roll out an electric sedan with a 200-mile range and a price of around $35,000. Designed to compete with the BMW 3-series and Mercedes C-Class, a recent trademark application for the name “Model E” may indicate the name of this new, mass-market sedan. - Gas2.org|
Elon Musk says mass market Tesla car (Model E) will have a ~48kWh battery, be 80% the size of the Model S
There is a lot of interesting info from a talk that Elon Musk gave at the CPUC last week. Of particular note, Musk gave some spec estimates for the mass market “Model E” vehicle expected to be released in 2017 with batteries coming from the Gigafactory. In the video above he says the car will have a 200 mile range and be 20% smaller than the Model S. Therefore the battery will need to have about 80% of the energy of the current Model S (Musk’s words). To be clear, since Tesla uses the constant sized 18650 cells (and looks to continue to do so) physical size and Watt-hours are fairly constant.
So given that a 60kWh Model S has a range of around 200 miles (EPA 208), that means that the Model E would need to have a battery around 80% the size of the Model S or 48kWh.
That’s still about double what leading ‘mass market’ electric cars have today. The Chevy Spark EV, with a range of 82 miles has a 21.3 kWh battery. The Nissan LEAF which has a 75 mile EPA range rating has a 24 kWh battery. The Chevy Volt has a 16kWh battery while the BMW i3 is 18.8.
