The Model S is the first fully Tesla-built car from the innovative California electric vehicle maker, following the Roadster, which had relied on an external body and chassis maker.
The Model S initially launched in 2012, and has become more refined in just a few years.
Recently, Tesla revised its Model S offerings to the 70, 70D, 90D and P90D.
This example is the 90D, which has a 90-kilowatt-hour battery pack and two drive motors, for all-wheel-drive.
The 90D represents a significant upgrade from the original Model S 85, adding range and all-wheel drive.
The Model S packages its battery pack, made up of lithium ion cells, in the chassis.
The 90D gets two electric motor, each making 259 horsepower, front and back. The total horsepower output comes to 417.
Being an electric vehicle, the Model S has no tailpipe emissions.
An optional air suspension contributes to comfort and handling.
The power steering and climate control are, of course, electric.
Because of the unique nature of an electric drivetrain, you can set the car to creep when you aren't touching the accelerator or brake, or stand still.
The 90 kilowatt-hour battery pack gives the Model S 90D a range of 288 miles.
The Model S is designed for exceptional aerodynamics and light weight, to maximize battery performance.
The EPA rates the Model S 90D at 100 mpg equivalent for a combined city/highway cycle, a testament to the electric drivetrain's efficiency.
The air suspension automatically lowers at speed to improve aerodynamics.
The electric motors are much smaller than an engine, leaving room under the hood for cargo.
The hatchback allows versatile cargo space.
It takes hours to charge up the Model S 90D from a Level 2 240-volt charging station, but Tesla's free Superchargers add 170 miles of range in half an hour.
A panoramic sunroof is a nice touch for the cabin.
The cabin, lacking a transmission tunnel, is very spacious.
