Somehow we missed this engine at the 2019 SEMA Show, probably mistaking it for two V-8s placed very close together. A V-16, after all, is not something you see very often, and a brand new one is even more unexpected. It's from Sixteeen Power Performance Marine Engines, hailing from the metro Detroit area, and comes in flavors from a naturally-aspirated 900 horsepower to a twin-supercharged 2,000 hp. And in case you're wondering, yes, Sixteen Power will build an automotive version of the engine on request.

First, though, why a V-16? We talked to Sixteen Power's Tom Robinson, who explained that he was looking to offer more reliability in a high-horsepower marine engine. V-8s making 1200 hp and beyond don't hold up, don't come with a significant warranty, require race gas, or any combination of those three. "The whole idea is to replace the V-8s that people are using in boats with an engine that's less stressed and will be more reliable," says Robinson.

There's no replacement for displacement.
