People spray-painted a Tesla dealership, punctured tires and scratched vehicles in apparent protest of Elon Musk, who has made repeated jabs at Canada.

There's wind power, solar power, and—tire power. Sumitomo Rubber is developing a new tire that can restore energy to a car as it drives down the road. The energy recaptures static electricity generated when the tires deform and return to their original shape as they roll down the road. Recovering energy from a portion of tire rolling...

General Motors and Michelin are testing airless tires on a Chevy Bolt EV. Plans are revealed for a mid-sized Mercedes-Benz electric sedan. Tesla puts real cash pricing up front on its website. And our Twitter followers answer what matters most to them when fast-charging on an extended trip. All this and more on Green Car Reports. As transportation...

Michelin yesterday revealed a comprehensive look at what some cars could be rolling on in just five years: the company’s first airless passenger-vehicle tire. The Uptis Prototype (Unique Puncture-proof Tire System) is a wheel/tire combination made primarily of rubber, aluminum, and a new resin-embedded fiberglass-reinforced material...

One of the many tactics used by carmakers to boost efficiency in their vehicles is fitting low-rolling-resistance tires. Specially designed to reduce the energy wasted as heat from the friction between the tire and the road, these tires can boost efficiency by a few percentage points in an electric car. The increase often isn't as noticeable in...

Although electric cars offer numerous benefits in engineering, design, and zero-emission operation, their overall weight remains a hurdle for automakers, especially as bigger batteries with longer ranges become more important. It now appears that Toyota may look to airless tires as a way to cut weight in its future electric cars: It debuted the...
