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.

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.

  • TheMrFreeze I don't doubt that trying to manage a company like Stellantis that's made up of so many disparate automakers is a challenge, but Tavares asking for so much money is simply bad form. With the recent UAW strike and the industry still in turmoil, now is not the time. And as somebody with a driveway full of FCA products, I'd just like to say how much I miss Sergio and FCA. At least with him Chrysler and Dodge stood a chance of long term survival...
