Ford

Electric vehicles, equipped with a special manufactured sound at low speeds, are already hitting the car lots. The U.S. government will require the otherwise quiet vehicles to make noise by September 2020, to alert blind, visually impaired and distracted pedestrians.

Porsche

Porsche will display its 919 Hybrid LeMans Challenger race car for the first time in the United States at Cincinnati's Concours d'Elegance Sunday, June 8. This "show car" (without an engine) will give car enthusiasts a glimpse of the vehicle that will race at the World Endurance Championship and 24 Hours of Le Mans June 14.

The car manufacturer last showed off the sports car at the 2014 Geneva, Switzerland Motor Show.
