The man who drove his 20-year-old Mustang from Napoleon, Ohio, to Las Vegas and back last year on 39 gallons of fuel will open his first manufacturing facility Monday to allow others to get 110 miles per gallon. Doug Pelmear, owner of Horse Power Sales.net Inc. and Hp2G LLC, will hold an open house ... in Wauseon to begin manufacturing his revolutionary engine. The factory ... will be tooled to initially turn out 20 of Mr. Pelmear's custom engines per day with one shift of 25 workers. A Decatur, Ind., specialty car company, Revenge Designs Inc., has contracted with Mr. Pelmear to purchase 2,000 engines for use in a new vehicle it plans to unveil at the end of this year at the Los Angeles International Auto Show. The vehicle is to be called the Revenge Verde Super Car, which will use Mr. Pelmear's 400-horsepower engine and its 500 foot-pounds of torque to travel up to 200 mph and get 110 mpg - though admittedly not at the same time. The engine is going to be a really great partnership with the car," explained Emily Levault, a spokesman for Revenge Design. "The idea behind this was to give people what they want while putting people back in their jobs." Ms. Levault said the Verde will be introduced as both a left and right-hand drive, so that it can be marketed around the world. Mr. Pelmear has said that he employs more precise tolerances and manufacturing techniques to decrease heat and energy loss and increase the efficiency of the internal combustion engine. He said he has more than quadrupled the industry average engine efficiency of about 8 percent.
