The 2.4-liter naturally aspirated V8’s used in Formula One will be retired at the end of next year, to be replaced with 1.6-liter turbo inline fours. WTF is naturally the first thing that comes to mind, and it’s true that we know little about the character of 1.6-liter turbo inline fours. But if 1.5-liter turbo inline fours are any clue, they will be okay. This is BMW’s M10 engine from the ’80s. With four cylinders, 1.5 liters of displacement, and a KKK turbocharger the size of an asteroid, it was good for 1,500 hp in qualifying trim. It glows cherry red on high revs, like it should.
