This video is specific to Jeep's Selec-Trac system on the Liberty, but is still a great explainer for how four-wheel drive works and when to use it.

I don't believe this video was intended to be instructional but any serious driver can certainly learn a thing or two watching Ayrton Senna thrash an NSX-R around Suzuka. Whoever decided to mount a foot camera to the NSX deserves a trophy.

This list has been heavy on 1930s Chevrolet videos, but there's a very good reason for that. As always, great visuals are employed in showing how the springs and shocks in your car absorb the bumps in the road.

This video was produced by the Department of Defense which, I know, isn't really what you'd call a carmaker. They were, however, a major driving force in the development of automatic transmissions. I simply couldn't not include this video that explains the mystery of how they work. Spoiler alert: it's not wizardry!

Dual clutch transmissions are becoming an increasingly large part of the automotive world, so this short, sweet video from Volvo Trucks is both excellent and timely. I'd imagine Porsche's PDK explanation video would be 4 hours, not 40 seconds like this one.

Don't know the difference between drum and disc brakes? You will within 7 seconds of this excellent video from Studebaker. As if you needed any more reason to want a Lark.

Who else but Mazda to tell you how a Wankel Rotary engine works? Even if a Rotary isn't really better than internal combustion as Mazda says, this is video is well worth your time.

Is there any better instructional video than Carroll Shelby, Ken Miles, Pete Brock, and Dan Gurney teaching you how to race? Add in Willow Springs Raceway as well as a Cobra, a Mustang GT350, and an early GT40 and you've got the best instructional video a carmaker has ever made.
