Marion G. Pottinger is an American mechanical engineer known for his work on tire footprint mechanics, tire wear and tire force and moment behavior. [1]
Pottinger holds a BS in mechanical engineering from the University of Cincinnati and an MS (1963) and a PhD (1966) in mechanical engineering from Purdue University. [2] [3]
Pottinger began his career with the research and development unit at B.F. Goodrich, rising to the rank of senior manager. In 1985 he joined Uniroyal Goodrich Tire Company, where he held an Associate R&D Fellow position responsible for development of high performance tires and for measurements of tire wear. In 1988 he joined Smithers Scientific Services. He retired from Smithers in 2003 as Technical Director. In retirement, he operated a private consulting company M'gineering.
Pottinger served as president of the Tire Society and was a member of several SAE committees: the Highway Tire Forum Committee, the Vehicle Dynamics Standards Committee, and the Chassis and Suspension Committee. He was a member of the ASTM F-09 Committee on Tires. Pottinger served as a member of a Transportation Research Board committee that was influential in writing legislation on tire energy consumption labeling. [4]
His most cited work gives a model for combined tire cornering and braking forces. [5]
The Goodrich Corporation, formerly the B.F. Goodrich Company, was an American manufacturing company based in Charlotte, North Carolina. Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Dr. Benjamin Franklin Goodrich, the company name was changed to the "B.F. Goodrich Company" in 1880, to BFGoodrich in the 1980s, and to "Goodrich Corporation" in 2001. Originally a rubber manufacturing company known for automobile tires, the company diversified its manufacturing businesses throughout the twentieth century and sold off its tire business in 1986 to focus on its other businesses, such as aerospace and chemical manufacturing. The BFGoodrich brand name continues to be used by Michelin, who acquired the tire manufacturing business in 1988. Following the acquisition by United Technologies in 2012, Goodrich became a part of UTC Aerospace Systems.

He was awarded the Padma Vibhushan, India's second highest civilian honour, on 26 January 2009.
Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation of the wheel, roadbed, etc., is recovered when the pressure is removed. Two forms of this are hysteresis losses, and permanent (plastic) deformation of the object or the surface. Note that the slippage between the wheel and the surface also results in energy dissipation. Although some researchers have included this term in rolling resistance, some suggest that this dissipation term should be treated separately from rolling resistance because it is due to the applied torque to the wheel and the resultant slip between the wheel and ground, which is called slip loss or slip resistance. In addition, only the so-called slip resistance involves friction, therefore the name "rolling friction" is to an extent a misnomer.
Paul B. MacCready Jr. was an American aeronautical engineer. He was the founder of AeroVironment and the designer of the human-powered aircraft that won the first Kremer prize. He devoted his life to developing more efficient transportation vehicles that could "do more with less".
Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.
Charles J. Pilliod Jr. was an American business executive and diplomat. He was ambassador to Mexico from 1986 to 1989.
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
The fuel economy of an automobile relates to the distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of the volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since the importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers such as sudden acceleration and heavy braking waste energy.
The Tire Society is a non-profit professional body, specifically an engineering society, whose mission is to increase and disseminate knowledge as it pertains to the science and technology of tires. It hosts a two-day meeting and conference every year. In addition, it publishes a peer reviewed technical journal, Tire Science and Technology.
Andrew Alfonso Frank is an emeritus American professor of Mechanical and Aeronautical Engineering at University of California, Davis. He is recognized as the father of modern plug-in hybrids, and coined the term Plug-in Hybrid Electric Vehicle (PHEV).
Energy-efficient driving techniques are used by drivers who wish to reduce their fuel consumption, and thus maximize fuel efficiency. The use of these techniques is called "hypermiling".
