The 2014 Green Car Technology Award will be awarded at the Washington Auto Show in Washington, D.C. later today.

The 2014 Green Car Technology Award is Green Car Journal’s creation rewarding green technology. Finalists are known and include a wide array of technologies from U.S., European, and Asian auto manufacturers.

“Advanced technology plays an increasingly important role in the development of cars and trucks capable of achieving significantly greater levels of efficiency and improved environmental impact,” said Ron Cogan, editor and publisher of Green Car Journal and “While new and advanced vehicle models get the limelight, it’s these underlying technologies that make their amazing achievements possible. Their crucial role is acknowledged through the Green Car Technology Award at the Washington Auto Show.”

Green Car Journal is a printed publication focusing on the intersection of automobiles, energy and environment since its launch in 1992.

The ten finalists are, as described by the award body:

  • Acura’s Sport Hybrid SH-AWD Powertrain: This three-motor, all-wheel drive Earth Dreams sport hybrid system blends high levels of performance and efficiency.
