RSS1844 Mazda Motor Corporation has developed a regenerative braking system for passenger cars capable of improving fuel economy by approximately 10 per cent. The new i-ELoop (intelligent energy loop) system, claimed to be the first of its kind in the world to use a capacitor, will begin to appear in Mazda vehicles from 2012.

i-ELoop efficiently converts the vehicle’s kinetic energy into electricity as it decelerates, using the electricity to power the climate control, audio system and numerous other electrical components. The innovative capacitor technology can store large volumes of electricity and, unlike batteries, can be charged and discharged rapidly and is resistant to deterioration through prolonged use.

Mazda claims that, unlike the regenerative braking systems found in hybrid vehicles, its highly efficient solution avoids the need for a dedicated electric motor and battery. i-ELoop features a new variable voltage(12-25V) alternator, a low-resistance electric double layer capacitor (EDLC) and a DC/DC converter. The system starts to recover kinetic energy the moment the driver lifts off the accelerator pedal and the vehicle begins to decelerate. The variable voltage alternator generates electricity at up to 25V for maximum efficiency before sending it to the EDLC for storage. The capacitor, which has been specially developed for use in a vehicle, can be fully charged in seconds. The DC/DC converter steps down the electricity from 25V to 12V before it is distributed directly to the vehicle’s electrical components.

    Increasing numbers of US customers are turning to alternative fuel vehicles, according to the latest research from Mintel, which shows that sales are up 73%, with nearly 440,000 hybrid, plug-in hybrid, and electrics sold thus far this year. The rapid sales growth in hybrid and electric vehicles makes the segment the fastest growing in the US for 2012, supplanting the still fast growing, compact car vehicle segment. The number of plug-in and electric models available to the public has nearly quadrupled over

    Car and ride sharing is just one example of the new on-demand economy allowing real-time matching of supply and demand through connected smartphone applications. According to ABI Research, successive forms of vehicle sharing approaches represent paradigm shifts in uptake and popularity; each new generation seeing adoption rates at least an order of magnitude larger than the previous: Car sharing 1.0 - street rental service: Cars parked on the street can be located, unlocked, used, and left behind.

    In an effort to help improve vehicle safety, the US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) has proposed a new standard that would capture valuable safety-related data in the seconds before and during a motor vehicle crash. The proposed rule would require automakers to install event data recorders (EDRs), devices that collect specific safety related data, in all light passenger vehicles beginning in September 2014. “By understanding how drivers respond in a cras
