Recharge Wrap-up: Mercedes-Benz B-Class Electric Drive goes on sale in Europe, Spain gets Nissan Leaf taxis

The new Mercedes-Benz B-Class Electric Drive goes on sale in Europe on November 3, with deliveries starting before the end of the year. Developed with the help of Tesla, the new electric B-Class offers more than 132 kilowatts (177 horsepower) and 250 pound-feet of torque. It features Economy Plus, Economy and Sport driving modes. An optional radar support system uses the collision prevention assist sensors to help make smarter decisions about when and how to use the regenerative braking. The B-Class Electric Drive also offers an optional Range Plus button, which can unlock more battery capacity when charging for the occasional longer drive. Learn more in the press release below. Racing returns to the streets of Miami for the first time in more than a decade for the Formula E Miami ePrix on March 14, 2015. Formula E has revealed the track layout, which takes the race around the Miami Heat's home court, American Airlines Arena, along the Biscayne Bay. "This event will help to make Miami more of a sports city," says Mayor Thomas Regalado. "In addition, we will show the younger generations that you may have motor racing without noise or pollution." Read more about the event at the Formula E website and see the track layout in detail here. Hyundai has delivered the first ix35 Fuel Cell vehicles to customers in the UK, including clean energy company ITM Power. ITM is responsible for three of the hydrogen refueling stations being built around the EU as part of the Hydrogen For Innovative Vehicles project - the same project that helped bring the Hyundai ix35 (also known as the Tucson) Fuel Cell to Europe. ITM's 700-bar hydrogen stations will be built in London by Spring 2015, each with its own electrolyzer system on site. In the meantime, ITM will use the ix35 for commutes between London and Sheffield, refueling at a site that uses wind-generated electricity from an on-site turbine to power the electrolyzer to make the hydrogen.

Aluminum supplier Novelis says demand will likely increase 30 percent annually for the next 10 years in China, Japan and Korea, and possibly more depending on how China's plan to increase EV use and decrease air pollution shakes out.

2015 Mercedes-Benz ML400 Quick Spin

Mercedes-Benz has taken a risk in its quest to downsize its engine range. For 2015, the brand's popular M-Class five-passenger CUV did away with its trusty 4.4-liter, twin-turbocharged V8, and has replaced it with a 3.0-liter, twin-turbocharged V6. It's no surprise that power is down thanks to this move. Outputs of 402 horsepower and 443 pound-feet of torque are replaced by 329 hp and 354 lb-ft, but weight is down significantly as well. The new ML400 is nearly 300 pounds lighter than the 4,982-pound ML550. Will that tradeoff be enough to satisfy a buying public that's embraced falling fuel prices by buying bigger and thirstier vehicles? To find out if the blown V6 is a suitable replacement for the twin-turbo V8, we spent a week at the helm of the all-new ML400. Driving Notes This 3.0-liter, twin-turbocharged V6 is the same engine being offered in the C400 and E400 sedans. Typical of today's turbocharged engines, peak torque is spread lavishly across the rev range, from 1,600 to 4,000 rpm. That's not as generous a spread as the ML550, which offers all its torque between 1,600 and 4,750, but the power on offer is easy to access. Importantly, the new V6 never feels flat-footed or unable to answer our commands. In fact, the ML400 feels even quicker than its six-second sprint to 60 would indicate, although it's not so fast as to challenge the 5.3-second time of the ML550. After a slight and expected bout of turbo lag, the power arrives suddenly and proceeds linearly until just south of the engine's 6,500-rpm redline. The throttle response is soft in Eco mode, as expected, but sharpens up slightly when the fuel-sipping mode is off, where the gas pedal is still easy to modulate. It's a quiet engine, too. Compared to the brawnier exhaust note of the old ML550 or the howling six-cylinder in the BMW X5 xDrive35i, the ML400's note is smooth and refined, befitting of a V6. Its turbocharged nature is instantly noticed, though. Get on the throttle and the 3.0-liter happily hisses its way up the tachometer. But, it's only when you get on the throttle hard that the engine really weighs in. In day-to-day driving and traffic its soundtrack is unobtrusive and relaxed. The EPA rates the ML400's fuel economy at 18-miles-per-gallon city and a 22-mpg on the highway. That's better than the 14 city and 19 highway of the old V8 ML, but it still seems a bit low, especially for the highway figure.

Daimler, BMW partnering up on wireless charging

Plug-in vehicle advocates can get all warm and fuzzy about two Germany heavyweight automakers getting together for the sake of wireless charging. That's because Mercedes-Benz parent Daimler and BMW will work together to speed up development of a wireless charging system. While not a ton of details were divulged, we can still rejoice. Daimler says the system will consist of an on-board coil and another coil that can be placed within the garage floor or someplace similarly stationary. The system will charge at 3.6 kilowatts and with 90 percent efficiency. No details were released about the system's price or when it would be available, but Daimler shouldn't wait too long, since other OEMs are already talking about their own wireless charging systems. Daimler obviously has some skin in the game here, since Mercedes-Benz will start sales of its S500 plug-in hybrid in September. That model, which was first shown off last August at the Frankfurt Auto Show, can go as far as 20 miles on electric power alone and will get fuel economy of about 84 miles per gallon equivalent. And it's easy to imagine an i3 or i8 driver getting a kick out of never needing to touch a cord. This spring, reports sprung up that fellow German automaker Volkswagen was preparing a wireless charging option for its electric vehicles as soon as 2017. You can check out Daimler's press release below. Wireless charging of electric drive and plug-in hybrid vehicles: PLUG IN HYBRID - unplugged One of the next steps on the way to perfect electric drive and plug-in hybrid vehicles is wireless charging. Daimler and BMW have now agreed on jointly developing and implementing one common technology. Wireless charging of the battery will make the handling of electric drive and plug-in hybrid vehicles even easier. Mercedes-Benz will commence fleet testing of this "unplugged" technology with the S 500 Plug in HYBRID soon, in order to develop a real S-Class solution in recharging the high voltage battery in terms of comfort and ease of operating in the near future. The system consists of two components: a secondary coil integrated into the under tray of the car and a primary coil integrated into a floor plate that can be placed on a garage floor for instance. Electrical energy is transmitted contact-free without the need for a cable, at a power rate of 3.6 kW and with a degree of efficiency of 90%.
