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%.

Mercedes may end Tesla supply agreement for B-Class Electric Drive

The Mercedes-Benz B Class Electric Drive has only been rolling off the production line for 17 months, each one equipped with a battery pack and drivetrain from Tesla Motors, but already there is talk of big upcoming changes. According to a report from the German publication Auto Motor und Sport, the next-generation version of this model will see an end to the Tesla-supplied tech and a hugely improved range. Currently, the electric sedan gets an EPA-rated 87 miles of range, using 28 kWhs of its 36-kWh battery, though its now-standard "Range Plus" package takes advantage of more of the pack, stretching that driving to 100 miles or so. It may take a year or several – the model just had a refresh – but expect those distance digits to double. The rumored range is said to be 500 km (310.7 miles), but since that would likely be calculated using the European drive cycle, expect something significantly lower stateside; say 220-ish official miles. This would be in keeping with expectations from a number of battery-powered competitors in the 2017-2018 time frame. It is unknown if this supposed next-gen B Class Electric Drive is in any way related to the rumored "Ecoluxe" program. The Tesla/Daimler relationship stretches back to 2009, when the Stuttgart-based outfit made a significant investment in the California automaker, quite possibly saving it from extinction in the process. We have reached out Mercedes-Benz about this report, but as of this writing, have not had a reply. We will update this post when we hear back.

2017 Mercedes-Benz C300 Coupe Quick Spin

Now that Mercedes has completed its rollout of four-door C-Class variants, it's time to subtract two doors and get down to the business of sport. The sedan smashed the entry-level luxury paradigm by being good enough to (maybe) keep you from aspiring to an S-Class. The C Coupe, on the other hand, wants to keep you from looking sideways, to certain BMW and Audi competitors. Driving Notes An obvious feature it shares with the sedan is its sense of maturity. The sheetmetal and proportions convey gravitas. The long-hood-into-short-tail that is The Mercedes Way gets another handsome showing here. There's an additional 2.4 inches between the bulkhead and the front axle – although to our eye that trim, curt rear end is overwhelmed by the visual weight of the rest of the car. It looks better on the AMG C63, where flared wheel arches put more emphasis in back. The front and rear of the coupe are altered from the sedan design. The crease under the headlights curves down into the lower intakes forming a continuous design element to the bottom of the curved lower lip. In back, the minimal taillights of the sedan get stretched across the fenders and the wider, straighter trunk of the coupe. The two-door is 1.5 inches lower than the sedan. Although the they share the same width, the coupe looks wider from the rear. Other markets will get a choice of four gasoline and two diesel engines. In the United States, we'll get the rear-wheel-drive C300 next spring with its 241 horsepower and 273 pound-feet of torque, same as in the sedan, with a seven-speed automatic transmission. After that will come a 4Matic version, and in summer comes the AMG C63. Mercedes hasn't broached the subject yet but our market should follow the sedan route, skipping the standard C400 to get the C450 AMG 4Matic with 362 hp and 384 lb-ft. At some point in the undisclosed future, the coupe will be upgraded to the nine-speed automatic. The interior is a delight, but that's what we're used to here – the materials look and feel excellent. The COMAND screen placement is still a hot-button issue, and we think the bezel-to-screen ratio is out of whack. Buyers don't seem to care. This year, the C-Class is just a couple thousand units behind the barn-busting 2013 numbers. In spite of the additional swoopiness versus the previous coupe, the larger size means larger interior dimensions everywhere – trunk space grows by 20 percent.
