Students from the Middle Tennessee State University (MTSU) have developed a plug-in hybrid retrofit kit. The eco-friendly kit is said to work with almost any car to turn it into a hybrid vehicle. The best part is, the cost of the technology would run around $3,000 if it's commercialized.
MTSU Professor Charles Perry recently fitted the hub technology on a 1995 Honda station wagon, increasing the vehicle's gas mileage by 50-100%.
"The whole point was to demonstrate the feasibility of adding the electrical motor to the rear wheel of the car without changing the brakes, bearings, suspension -- anything mechanical," he said.
