  • How carbon ceramic brakes are made

    Although carbon-ceramic brakes will outperform cast iron rotors all day, there's a good reason why only the most high-performance cars wear them. Foremost, they cost thousands of dollars, but ever wonder why? The manufacturing process behind carbon-ceramic brakes is extravagant, to say the least. A video shows the exact process and it's not your average assembly line. The brakes start life as raw materials: heat-moldable resin and chopped pieces of raw carbon fiber. As they head through the production process, machines pour the mixture into a mold the shape of the disc. The process doesn't...

  • Why do diesel engines make more torque than gasoline engines?

    Horsepower is fun in its own way, but torque can be just as entertaining. If you want to rip stumps out of the ground, you'll want a whole lot of torque. That also means you'll likely prefer a diesel engine. Compared to their gasoline-swilling counterparts, diesel engines are the torque kings. Why is that? Jason Fenkse from Engineering Explained knows why, and he's here to offer up five reasons why a diesel engine makes more torque than a comparable gasoline engine. First up is compression ratio. With a gasoline engine, the piston stops a bit short of the top of the cylinder as it moves up...
