root of engine inefficiency. In
April, Swedish supercar-maker
Koenigsegg debuted the world’s

first camless engine—the
FreeValve—on a Chinese Qoros
concept car. FreeValve forgoes

the camshaft for electro-

hydraulic-pneumatic actuators.

They attach right to intake and

exhaust valves, so engineers

can control combustion within

each cylinder. The design gets

more power—imagine a four-

cylinder getting 185 kilowatts,

sans turbo—and greater fuel

economy out of otherwise

standard engines. Cams, may

you rest in peace.
