A few weeks ago, I went to the amazing Auburn Cord Duesenberg Automobile Museum in Indiana, where I learned about an axle that has not just one gear ratio like in pretty much all modern cars, but ...

In first gear, the gear ratio of 3.64-to-1 means that for one transmission revolution, the engine turns 3.64 times. From there it turns the differential, which has another gear called final drive.

Opinions vary on what constitutes a "granny transmission," but in a nutshell it's a manual transmission with an extremely low gear ratio that allows the vehicle to crawl along at a super-slow pace ...

A transmission is a vehicle’s gearbox. It’s roughly analogous to the gear shifter and chain system employed in bicycles. Transmission components are always mounted straight on the engine so that their ...

Most electric cars have a single gear ratio. You probably understand the basic reasons for this, but the math is still super fascinating.
