Build Your Own Cadillac Sixteen With This 14-liter LS

The Bugatti Veyron Grand Sport Vitesse produces 1,200 horsepower from its tightly packed quad-turbocharged W16 engine. It is a modern marvel that takes four camshafts and 64 valves to move all the air needed to make this power, and it sure doesn’t come cheap.

An oil change for the Veyron costs slightly more than a new Fiesta ST and requires an engine disassembly due to the extremely tight tolerances. We aren’t likely to find a W16 for sale anytime soon and, even if one does pop up, it won’t go for less than six figures. Not to worry, as a company out of Michigan may have a much better solution — one that makes just as much power with half as many valves and no forced induction.

The Supreme Court said they couldn't forgive student load debt; they did it anyway. Decorum and tradition says you don't prosecute former presidents; they are doing it anyway. They made the CDC suspend evictions though they had no constitutional authority to do so.
