Mazda to use regen brakes to boost fuel economy 5 to 10 percent

Mazda is adding a fuel-saving technology that harnesses wasted brake energy in the redesigned Mazda6 sedan due early next year. The approach uses regenerative braking to convert kinetic energy into electricity that is stored in a capacitor. The car later taps that capacitor to power the fuel pump, lights, audio, air conditioning and transmission and engine control systems.

NY Times reporter says he followed Tesla's advice

A New York Times reporter says he was following the advice of Tesla employees when he drove an electric Model S sedan beyond its indicated range in an effort to reach a recharging station. Responding to a blog post by Tesla Motors CEO Elon Musk highly critical of his original article, Times reporter John Broder on Thursday said he did not set out to sabotage the test drive -- refuting one of Musk's most-damning points. Broder also refutes Musk's claim that he drove the car around a parking lot in a deliberate attempt to fully discharge the battery -- Broder says he was looking for the recharge station in a poorly lighted rest stop at night.

Armor-plated SUV among extravagant debuts at Top Marques Monaco show

While AutoWeek editors were pounding the pavement at the New York auto show last week, the world's silly rich were nodding polite approval at the Top Marques Monaco show. Included in the debuts were Gemballa, Fisker, Keating, Tirrito and Conquest, the latter of which showed off a ridiculously large, armor-plated SUV called the Knight XV that reportedly took organizers three hours just to maneuver it through the hall doors. Lest we forget that we're all human, Top Marques Monaco also had its “Black Friday at Wal-Mart” moments: According to organizers, Gemballa's world premiere of the Tornado was cut short after it was purchased “within 16 seconds of the show doors opening by a sheikh eager to have a piece of the action.” Full wrap-up release from Top Marques Monaco below.
