Being named to this list is evidence that Protean Electric’s in-wheel electric drive has a bright future in the global auto industry, according to Car and Driver, the world’s largest auto enthusiast magazine. This list of Most Promising Technologies accompanies Car and Driver’s 10Best Cars celebration, which has existed for more than three decades.
Car and Driver’s technical director, Don Sherman, author of the Most Promising Technology feature, is a strong believer in the potential of in-wheel and wheel-hub motors for coming electric and hybrid-electric automobiles.
“Integrating the propulsion system with the wheel hubs will enable designers and engineers to achieve major gains in packaging efficiency, fuel economy and, potentially, performance,” he noted. “We expect Protean Electric, the leader in this field, to help manufacturers implement this technology.”
“To be named a leader and one of the Most Promising Technologies by Car and Driver is an immense honor. This recognition indicates that the industry is no longer thinking of ‘if’ but ‘when’ in-wheel motors will be commonly used across a wide range of vehicles. And we believe that when is now,” said Protean Electric Chairman and CEO Bob Purcell.
