Lock up your flywheels, folks, an American inventor is coming after them. Randy Moore of RK Transportation is working on an idea that replaces an engine's flywheel with a lightweight rotor with ...

Tests on public roads has shown that Volvo's experimental kinetic flywheel hybrid system can improve car fuel efficiency by up to 25 percent. A car with the system and a four-cylinder turbocharged ...

Imagine how fast acceleration would be and how much lighter a motorcycle would be without a heavy flywheel. That’s the idea of American inventor Randy Moore of RK Transportation who has developed a ...

Earlier this year at the Detroit Auto Show, we heard about Porsche’s hybrid race car that garners energy from a flywheel, and now a consortium called Flybus has put that energy reusing technology into ...

Ferrari, Renault, BMW, and McLaren have all used kinetic energy recovery systems (KERS) in F1 racing. Now Volvo wants to bring the technology to road cars. Volvo received a grant from the Swedish ...

Of all the ideas to save gas, this is one of the ones that was straightforward and held some of the most promise. Yet no one could seem to make it work. Until now. It's the flywheel. Volvo says it has ...

In the first part of this project series we learned of my experiences with a slipping clutch--a problem I was having after only a couple of baseline quarter-mile test runs. The second write-up ...

In order to help boost their range, many electric and hybrid cars employ regenerative technology where braking energy is stored in the battery instead of simply being wasted. This idea can also be ...

Here’s a fuel-saving technology for a range of vehicles you probably haven’t heard about in a while: flywheels. Designed to capture and re-use braking energy, flywheels are now being tested not just ...
