Supersize Me: The 16 Largest-Displacement Engines You Can Buy Today

Car and Driver Logo By Andrew Wendler of Car and Driver | Slide 1 of 17: For most of the 20th century, automotive one-upmanship was all about big inches - cubic inches of displacement, that is. From Fiat’s massive 28.5-liter “Beast of Turin” four-cylinder to the 13.5-liter Pierce-Arrow T-head inline-six and the Mercedes-Benz 6.9-liter V-8 to Cadillac’s 500-cubic-inch V-8, big displacement was the simplest way to quickly turn tires and heads. And it worked for a while, until rising fuel prices and federal emissions standards teamed up to ruin the party. By 1976, even Cadillac’s epic 500-cube V-8 had been neutered, producing just 190 horsepower. But as the decades passed, manufacturers around the globe began to embrace newer technologies capable of enhancing both smaller- and larger-displacement powerplants alike. Today, big-inch engines not only are insanely powerful, they’re also dramatically more reliable and cleaner-burning than their fuel-guzzling forebears. Read on for a rundown of the 16 biggest production-vehicle engines you can buy today.
