Throughout the history of the automobile, flat-plane crank engines have been the domain of race cars and sports cars, an exotic alternative to those lumpy, cross-plane crank engines found in muscle cars and less sophisticated sports cars. But in 2015, Ford changed everything by putting a Ferrari-like flat-plane crank V8 engine in the Shelby GT350, complete with a glorious sound as it climbed its way up to its 8,250 rpm redline. Chevrolet took it even further, making the largest production flat-plane crank V8 with its 5.5-liter unit in the C8 Z06, which has an even higher 8,600 rpm redline and its own glorious sound.
