Small-displacement, turbocharged engines are seemingly the future of internal combustion—their big power and low fuel consumption make them ideal for today's engineering and regulatory challenges. But turbo lag sucks. And Volvo thinks it has the answer.

Meet PowerPulse, Volvo's proposed solution for turbo lag in the diesel-powered version of its all-new S90 sedan. In theory, it's astoundingly simple: A small electric compressor draws filtered air from the engine's intake, storing it at pressure in a small tank. When the driver mashes the accelerator, a valve routes the compressed air into the hot side of the turbocharger. The high-pressure air spools up the exhaust-driven half of the turbo, pressurizing induction air and, according to Volvo, eliminating the wait for pressurized exhaust to build up.

It sounds like a high schooler's daydream, but according to Volvo, it works:

Volvo says the technology completely eliminates turbo lag, and that a PowerPulse diesel-powered S60 sedan shows better acceleration than many gasoline-powered competitors. It's not clear if we'll ever get the chance to find out—Volvo hasn't indicated whether the diesel drivetrain will come to the US, and the automaker hasn't given out acceleration data yet. We'd prefer to test it ourselves before declaring turbo lag dead forever.

But if it does work as advertised, giving naturally-aspirated engine response to tiny turbo motors, this could be great for the future of internal combustion.
