Big Block With Four Turbos, Witty Headline Impossible

We had to reload this the first time it popped up, as we couldn't believe what our eyes were telling us. This serpentine piece of steel poetry is a 442 ci V8 sporting four independent turbochargers, all running through an intercooler. The entire system is modular and can be dropped into a drag-racing host as a single piece. Four turbos. Four! And big, bus-sized ones at that. The madmen behind this are Mike Moran and John Meaney, and they've whipped up a doozy of an engine.

GM to Achieve Mileage Targets With Logic, Turbos

Instead of throwing all of its cash down the yawning maw of biofuel and hydrogen fuel cells, GM intends to get some quick fuel economy wins the smart way - with lower displacement and turbos. Automotive News (sorry, subscription required) is reporting GM will be following a strategy similar to Ford with its EcoBoost engines, namely using smaller engines in large vehicles, but bolstering them with the magic of exhaust driven compression. There's no speculation on when or in what we would see this strategy start to play out. We're on the torn here; big brutish V8's make us happy and can get decent mileage (see Corvette), but the fevered banshee scream of a turbocharged four banger is pretty rad too.
