(Read caption) A man looks at Tesla Motors' Model S P85 at its showroom in Beijing in January 2014. The Model S sold in May 2014 is quite different than one sold in June 2012, thanks to some new features and updates from Tesla Motors.

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.

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.

But under the surface, there are a surprising number of updates, additions, and new features, many of them additional-cost options.

Our thanks to communications manager Shanna Hendriks, who patiently compiled a list of all the hardware and options changes made to the cars since the start of 2013.

This list doesn't cover software changes, of which there are literally dozens, grouped into minor and major releases that are pushed over the air to the car once the owner gives permission for the update to occur. (That's an entirely separate article.)

Tesla owners will undoubtedly flag any hardware features we've left out, described incorrectly, or otherwise gotten wrong in the following list--but here's what Tesla Motors sent us.

"It should be noted," Hendriks wrote, that none of these are mandatory changes--they are merely options that have been added to the roster" of available equipment when ordering a new 2014 Tesla Model S.
