Tesla lets you turn your Model S into a James Bond car-sub.
If you access the technician login screen on the Tesla Model S and type in "007", the car, which is usually shown as a Model S, will change to the submarine car that James Bond used in the movie "The Spy Who Loved Me."
Though I wouldn't advise driving into any large bodies of water even with this mode engaged.
The Model S can also be driven on the rainbow road from Mario Kart if you know the right tricks.
To turn it on, you just have to turn on autopilot four times in a row.
Thankfully here there are no signs of those pesky kart-wrecking shells or angry racing competitors to watch out for.
The Volvo XC90 has something hidden for children who sit in the SUV's third row.
Instead of going with some generic plastic mold pattern on the inside of this storage compartment, Volvo's Vice President of 'Vehicle Line 90' Dennis Nobelius told Jalopnik that he decided to go with something a little more child-friendly.
The Jeep Renegade has a ton of easter eggs.
Not only are the rear tail lights designed to look like the old X marked metal fuel cans used during WWII, but if you look even closer, you'll find the classic Jeep front-end design printed in the center of the lens as well.
The Dodge Viper SRT has track outlines hidden throughout the cabin.
If you look at the plastic piece in front of the window switch, you'll find an outline of the incredibly famous Nürburgring Nordschliefe race track.
There's also a hidden outline of Mazda Raceway Laguna Seca as well.
