The Vision Mercedes-Maybach 6 is pure electric excess

The Vision Mercedes-Maybach 6 is a two-door, two-passenger coupe that spans over 18 feet long. Everything about this car is more than you need. But isn't that the true definition of ultimate luxury? With so much sheet metal, it can be tricky to get everything to look right, but Mercedes seems to have done nicely with this concept. Overall, the car's long nose and short deck are reminiscent of the Mercedes-AMG GT, and the long, tapering tail and lights are similar to that of the Mercedes-AMG Vision Gran Turismo concept from a few years ago. Capping off the front of the Mercedes-Maybach 6 is a proud, prominent grille that the company claims was inspired by a pinstripe suit. At each corner are 24-inch wheels with transparent panels based on the transforming, aerodynamic wheels of the Concept IAA Mercedes previously showed. Powering this massive coupe are four electric motors that can produce a combined 738 horsepower. Mercedes says that will be enough to get the car to 62 mph from a standstill in under 4 seconds. The motors are backed by an 80 kWh battery that the company says can propel the car up to 200 miles. Perhaps more interesting than its range is the fact that the Mercedes-Maybach 6 can pick up a charge worth 62 miles in just 5 minutes, assuming you've got the right charger. This is technology that could really make a difference in the day-to-day practicality of electric cars, provided that it makes it to reality. The car can be charged either by being plugged in, or wirelessly with an inductive charging system. Inside, the Vision Mercedes-Maybach 6 has even more fantastical features. It does retain analog gauges as a link to the past, but augments them with wrap-around glass trim that doubles as a display and touch-sensitive interface. The windshield seems to be pulled from Mission Impossible with its ability to display information. Sensors in the seats are designed to read the condition of the passengers and even their outfits to custom tailor everything from lighting to massage features. It's hard to say what the production odds are for this mega Mercedes, but you probably shouldn't hold your breath. Even for the rarified segment of seven-figure cars, this would be pretty extravagant. It wouldn't be impossible, or without precedent. Back when Maybach was still its own brand, the company created a ridiculous luxury coupe called the Exelero, and they sold the fully-functional car.

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

8 cars we're most looking forward to driving in 2015

Now that 2014 is officially in the books, it's time to look ahead. And following our list of the cars we liked best last year, we're now setting our sights at the hot new metal that's coming our way in 2015. Some of these, we've already seen. And some are still set to debut during the 2015 auto show season. But these are the machines that keep us going – the things on the horizon that we're particularly stoked to drive, and drive hard. Jeep Renegade Not the Chevrolet Corvette Z06. Not the Ford Mustang GT350. Not the new John Cooper Works Mini. Nope, I'm looking forward to the adorable, trail-rated Jeep Renegade. And that's because I really, really, really like our long-term Jeep Cherokee Trailhawk. I do not, however, care too much for the Cherokee's looks, and I really don't like its $38,059 price tag. The Renegade Trailhawk, meanwhile, promises much of the same rough-and-tumble character as its big brother, but at what we expect will be a more reasonable price (I'm personally wagering on the baby Jeep's off-road model starting at no more than $23,000). With a 2.4-liter four-cylinder and a nine-speed automatic, it should also be a bit easier to fill than the V6-powered Cherokee. Also, I can't help but love the way the Renegade looks. It's like someone took a Wrangler, squished it by 50 percent and then handed it off to George Clinton for a healthy dose of funk. The interior, with its bright, expressive trims and color schemes should also be a really nice place to spend some time. I'll be attending the Renegade's launch later this month, so I'll have a much shorter wait than my colleagues. Here's hoping the baby Jeep lives up to my expectations. – Brandon Turkus Associate Editor Mazda MX-5 Miata Here's an uncomfortable truth: I'd rather spend a day driving a properly sorted Mazda MX-5 Miata of any generation on a winding road than I would nearly any other vehicle, regardless of power, price or prestige. It's not just that I prize top-down driving and enjoy the Miata's small size because it gives me more road to play with. I just find there's more motoring joy to be had with high-fidelity handling and an uncorrupted car-to-driver communication loop than I do with face-distorting power or grip – let alone valet-stand gravitas. But perhaps most of all, I love Miatas because they can deliver that level of feedback and driver reward at modest speeds that won't put the locals on edge or endanger lives – you can use more of the car more of the time.
