For professional racing engine builders, the key to maximizing a power plant’s performance is engineering a combination of components that complement one another. In most cases, this requires either ...

Many performance cars, including the supercharged Chevrolet Corvette Z06 and most Ferrari GT models, rely on forged pistons — instead of cast-aluminum pistons — for their additional strength. Forged ...

Golf balls have dimples, so they fly farther than balls that don't. Apply the same principle to diesel engines, and you have a gross oversimplification of why dimpled pistons were invented. It's a ...

Technical manoeuvring to push regulatory boundaries for the slightest performance edge without actually breaking any rules is a familiar pattern in all forms of motorsport. Engineers treat the rule ...
