After many years of development and research, GM has created a driveable, street-worthy HCCI (Homogeneous Charge Compression Ignition) test mule (working concept vehicle) and put it on the streets of major metropolitan areas like Washington D.C. and greater New York City. Scott was one of the first automotive journalists to drive the Saturn Aura HCCI on the streets of New York, and here are the photos documenting his time spent with the HCCI test car. Click the thumbnails for more info, and for details and driving impressions check out Scott drives the Saturn Aura HCCI test mule.
