WINNER: Small water pump helps engines warm up swiftly
What: Electro-hydraulic controlled flow water pump
Innovation: The pump restricts coolant flow on cold starts so the engine warms up faster, reducing emissions and boosting fuel economy. A small hydraulic piston inside the pump regulates coolant flow, enabling a 40 percent reduction in pump size.
First customer: Volkswagen 1.6- and 2.0-liter engines, 2012
