Everyone knows there is no gasoline engine making a Tesla Model S go, but besides a motor and battery, have you ever wondered what the rest consists of under the skin?

If so, you’re not the only one, and IHS Technology also was more than a little curious to forensically tear one down and find out what electronics are being used in the Silicon Valley special.

The company bought a crashed 2013 MS, and inside they identified a slew of parts, said Andrew Rassweiler, a senior director at IHS Technology.

Some were from brand-name suppliers, others from companies you may have never heard of, and a surprising amount of componentry is designed in-house by Tesla.

One of the usual statements about EVs is they have fewer components making the car simpler, but the more-accurate ones making such statements speak of the powertrain being less complicated and potentially troublesome than in an internal combustion car.

The Model S is actually not unlike one large solid-state electronic device. Its electronics are comprised of a huge jumble of carefully assembled parts and sub-components. The sophisticated head unit alone has 5,300 – four times that of an Apple iPhone 5s, another device that IHS has torn down and examined.

The car’s large touchscreen in the centerstack was one thing that interested Rassweiler:

“The simple fact that there’s a 17-inch display controlling the vehicle. Kind of like a large iPad controlling your car” was intriguing, as was the fact Tesla designed this itself.

The full display is manufactured by Innolux, and other suppliers – and companies that stand to prosper as Tesla increases volume – include Nvidia, which supplied many of the chips in the Model S as well as Freescale Semiconductor, Texas Instruments, Qualcomm, STMicroelectronics, Altera.
