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%.

Alpina B4 coupe will be your subtle M4

We're big fans of Alpina here at Autoblog - the BMW tuner has created some seriously delicious products in the past, and recently tuned the diesel-powered 3 Series wagon to create the D3 Bi-Turbo. What we like most about Alpina is how the cars only look subtly more aggressive than stock, yet they pack a real wallop under the hood.
Take this B4 Coupe, recently spotted testing at the Nürburgring. It looks pretty tame compared to the normal 435i, the only visual additions being the Alpina-standard 21-spoke wheels, modified front lip and rear wing spoiler. But under the hood, Alpina is reportedly working on a tuned, twin-turbo straight-six that produces something like 410 horsepower. That means the B4 should be good for a 0-62 time of 4.2 seconds, with a top speed around 190 mph. Rear-wheel drive will be standard, though our spies suggest that Alpina could also use all-wheel drive here in the B4.
We have no doubt that the next BMW M4 will be super hot, but for those seeking a bit more stealth and exclusivity, this Alpina B4 certainly looks the business. Check it out in our gallery above.

BMW Z8, Lambo LM002 sell for $192,500 apiece in Detroit [w/poll]

Think a car are a bad investment? That all depends on what kind of car you're talking about. Because while most cars depreciate in value as soon as you drive them off the lot, others can do even better than hold their value. The cars that appreciate tend to be pretty high-end exotics, but they don't have to be multi-million-dollar classics to command a premium at auction. Just look at the results from RM Sotheby's Motor City sale in Detroit this past weekend. The auction house moved a solid $7.4 million worth of metal, which is pretty impressive when you consider that – unlike events at Lake Como or Pebble Beach – not one of the lots dipped into seven figures. 1930s-era American classics performed the strongest, with Duesenbergs, Packards, Auburns and the like all fetching hundreds of thousands. But what intrigued us most were the European exotics that rounded the top ten results. Amidst the Depression-era American steel were a BMW Z8 from 2001 and a 1988 Lamborghini LM002, each of which sold for an equal $192,500. Hardly the highest figures paid for European exotics this year, but considering how much they were worth just a few years ago, they've proven solid investments. BMW only made 5,703 examples of the Henrik Fisker-designed retro Z8, of which only 2,543 were brought to the United States, where they originally sold for $128,000. The most anyone had ever paid for one at auction, according to Sports Car Market, was $184,082, just this past March at Silverstone. That makes the price achieved this weekend a new record for one of the slinkiest vehicles the Bavarian automaker has ever made, representing an impressive 50-percent increase in value over the course of fourteen years. This particular example – chassis WBAEJ13481AH60437 for those keeping track – is decked out in silver over black, with less than 15,500 miles on the odometer. This Rambo Lambo was produced early in the 301-unit production run, with the sought-after carbureted engine and 32,000 miles on the clock. It didn't set any records at the same price, other examples of the LM002 having traded over the past few years for over $200k. But considering that Sant'Agata originally charged around $120-130k for the SUV when it was new, its selling price still represents about 50-percent appreciation (leaving inflation aside).
