The future of cars: Drivers not needed
Las Vegas (CNN) -- It's conventional wisdom in the auto industry, but the rest of us may be a bit shocked to find out that cars of the future likely will drive themselves.
In some ways, they already are.
A $100,000 car from Mercedes aims to give the human foot a rest in traffic jams. It senses how far away other cars are -- and then speeds up and slows down accordingly. No need to turn off cruise control and hit the brake. You just steer. (Wired Magazine, which tested the car, called this a "magically scary experience.")
And tech companies are pushing car automation even further.
In October, Google announced it had developed a fleet of cars that use various sensors and maps to feel out the roadway. "They've driven down Lombard Street, crossed the Golden Gate bridge, navigated the Pacific Coast Highway, and even made it all the way around Lake Tahoe. All in all, our self-driving cars have logged over 140,000 miles. We think this is a first in robotics research," the company said on its blog.
The EN-V (pronounced "envy" and short for "Electric Networked Vehicle") combines two ideas about how to teach cars to drive -- using sensors like cameras and sonar to keep the car from hitting pedestrians; and network technology that lets cars talk to each other.
This "car internet" lets the cars link up wirelessly and follow one another in a sort of wirelessly linked train. If one EN-V needed to pull out of the line, it could.
The pod-like cars, which are just prototypes for now (GM says they could be on the market by 2030 at a cost of $10,000), look somewhat like large scuba-diver helmets, or smushed dust busters. They roll on two wheels, which are aligned like the front two wheels of a car, not like a bicycle. GM partnered with Segway, maker of those futuristic-looking transporters, to create technology that allows the car to balance.
"It's basically a dynamically balanced skateboard," said Chris Borroni-Bird, GM's director of advanced technology vehicle concepts.
The EN-V runs on battery power and plugs into a wall -- giving it a max speed of about 30 miles per hour and a range of about 30 miles. That's not far or fast, but it's enough to make the EN-V useful for cutting down congestion in urban settings, particularly high-density cities in China and India, Borroni-Bird said.
The car also aims to improve safety, since human drivers don't have a sterling record on that front. An estimated 1.3 million people die in traffic-related accidents each year, according to the World Health Organization.
The EN-Vs are just as wide as they are tall, measuring 5 feet cubed. Two people fit inside comfortably, but there's not much room for anything else. A bubble of glass sits close in front of the driver's face. "You can probably pack 5 or 6 times as many of these EN-Vs in a parking lot as you could conventional cars," Borroni-Bird said.
Even though the cars can communicate with each other and drive themselves, drivers can take control if they choose. That's important, Borroni-Bird said, both for safety reasons and so drivers can get some sense of enjoyment from the vehicle.
Drivers use a joystick of sorts to steer and throttle the vehicle, which can spin in place and accelerates rather quickly.
Still, Borroni-Bird says, there are a number of obstacles that need to be hurdled before something like the EN-V hits the market.
The wireless signals that let the vehicles communicate are problematic because hackers, in theory, could access them and send cars off track; and because a lost wireless connection could cause the automated system to lose control of the car.
"It's one thing if a computer goes down, but it's another thing if it happens here," he said.
But he sees a bright future for the concept.
"For the last 100 years the car really hasn't changed in a fundamental sense," he said.

Mercedes SLS AMG E-Cell hitting dealerships in 2013
You may disagree with the car's color and its powertrain choice, but you can't argue with 528 horsepower, 649lb/ft of torque, and AWD acceleration so good it should come with a neck brace. It's a legitimately hot car, and it's legitimately coming to dealerships. Mercedes today confirmed that the SLS AMG E-Cell will be available for order at dealerships in 2013, and while no price was given, expect it to be a lot. The gasoline-powered model cost around $200,000, after all. Oh, and that citrus color? It's pretty stunning in the flesh, a matte hue that makes you go "Mmm."

Mercedes all electric SLS AMG E-Cell Gullwing to enter production
The Mercedes-Benz SLS AMG E-Cell
At the 2011 Detroit Auto Show Mercedes-Benz has announced that its SLS AMG E-Cell, which was first unveiled as a prototype last year, will go into production. Part of Mercedes-AMG’s “AMG Performance 2015” strategy that aims to continually reduce fuel consumption and emissions, the battery-electric drive gullwing super sports car, which generates 392 kW (525 hp) and 880 Nm (649 lb-ft) of torque via four compact electric motors positioned near the wheels, will be available to order from 2013.
The all-electric SLS AMG E-Cell can go from 0-100 km/h (0-62 mph) in 4 seconds, which isn’t far off the pace of the 6.3-liter SLS AMG that does it in 3.8 seconds thanks to its 420 kW (571 hp) V8. The planned production model looks to be largely unchanged from the prototype with the same liquid-cooled, 48 kWh lithium-ion battery pack, redesigned instrument cluster and center console and multilink suspension with pushrod damper struts. The production version will also offer AMG ceramic composite brakes, which are 40 percent lighter than the conventional, grey cast iron brake discs, as an optional extra.
Mercedes-Benz hasn’t released all the details about the car just yet though – most notably, the range of the vehicle, how long it takes to charge and the price.

Volvo to enter the EV market with all-electric C30
While it looks like a regular Volvo C30 with the same safety, comfort and space as featured in standard model the big difference is that the C30 Electric is powered solely by electricity
Volvo is set to enter the electric vehicle (EV) market with the production of an all-electric version of their C30 three-door compact. An electric concept based on the C30 was first seen in 2007 and last year the C30 Electric was taken to the Paris and Los Angeles Motor Shows. Now Volvo has announced its plans to begin production of the EV with the first ten cars off the production line heading to Swedish energy provider Göteborg Energi in the coming months.
While it looks like a regular Volvo C30 with similar safety, comfort and space as featured in the standard model, the big difference is of course that the C30 Electric is powered solely by electricity and produces zero local emissions.
The electric motor is housed under the bonnet and is powered by an Enerdel lithium-ion 24 kWh battery. It is charged using regular mains power with a completely depleted battery taking eight to ten hours to recharge. The EV has a range of 150 kilometers (94 miles) on a full charge, boasts a top speed of 130 km/h (approximately 80 mph) and accelerates from zero to 100 km/h in 10.5 seconds via its 82 kW electric motor.
These figures are comparable to the Nissan LEAF which has a 100 mile (160 km) range, 80kW motor, top speed of around 90 mph (140 km/h) and an estimated 8 hour recharge time.
The Volvo C30 Electric project has slated an initial production run of only 250 vehicles.
"We have had a very positive response from the market so far. If the demand continues to be high, we will of course expand our production series," Lennart Stegland, director of Volvo Car Corporation's Special Vehicles division said.
The new EV was at the 2011 Detroit Auto Show where at the company's stand featured a Volvo C30 Electric that had undergone a frontal collision test at 40 mph (64 km/h).
"Our tests show it is vital to separate the batteries from the electric car's crumple zones to make it as safe as a conventional car," Volvo Cars' President and CEO Stefan Jacoby said. "In Detroit we are the first car maker to show the world what a truly safe electric car looks like after a collision with high-speed impact."
Key specs – Volvo C30 Electric
Electric motor: 110 hp (82 kW)
Top speed: 81 mph (130 km/h)
Acceleration: 0-100 km/h in 10.5 sec

Re: Electric Car 及 Connected Car是趨勢!!
13 Japanese companies join to further fuel cell adoption, also plan to ride bikes together
What's going to spin the tires in your car of the future? Will it even have tires? Right now it looks like either hydrogen fuel cells or pure EVs will be dominating the streets in a few decades, and thankfully they share enough technology for us to think they can peacefully co-exist -- just like Apple and Microsoft fanboys and girls have been known to host really great parties together where they engage in long, respectful discussions regarding their differing opinions. However, while EVs are already well on their way, for fuel cells to take off we're going to need more hydrogen filling stations and more cooperation between auto manufacturers. That's happening now in Japan, with 13 companies -- Toyota, Nissan, and Honda along with a number of gas and utilities companies -- joining forces to enable a "smooth domestic launch" of fuel cell vehicles as soon as 2015. They hope to create about 100 hydrogen stations across the country, work to form a broader hydrogen supply network, and also educate people about FCVs in general. We'll give them a head start by letting you know that stands for "Fuel Cell Vehicle," though they're also often called FCEVs, or "Fuel Cell Electric Vehicles." Bam! Two items off the to-do list.

13 Japanese Companies Eye Smooth Domestic Launch of FCVs
-Development of Hydrogen Supply Infrastructure Key-
Toyota Motor Corporation (TMC), Nissan Motor Company, Ltd., Honda Motor Company, Ltd., JX Nippon Oil & Energy Corporation, Idemitsu Kosan Company, Ltd., Iwatani Corporation, Osaka Gas Company, Ltd., Cosmo Oil Company, Ltd., Saibu Gas Company, Ltd., Showa Shell Sekiyu K.K., Taiyo Nippon Sanso Corporation, Tokyo Gas Company, Ltd. and Toho Gas, Company, Ltd. jointly announce the following details regarding the launch of fuel-cell vehicles1 (FCVs) - one of a number of potential next-generation vehicles - in the Japanese market in 2015 and the development of the hydrogen supply infrastructure necessary for the successful adoption of the vehicles.
As development of fuel-cell systems progresses, Japanese automakers are continuing to drastically reduce the cost of manufacturing such systems and are aiming to launch FCVs in the Japanese market-mainly in the country's four largest cities-in 2015. The automobile industry hopes to popularize the use of FCVs after their initial introduction as a way of tackling energy and environmental issues.
Hydrogen fuel suppliers are aiming to construct approximately 100 hydrogen fueling stations by 2015, based on the number of FCVs expected to initially enter the market, to ensure a smooth launch and to create initial market.
With an aim to significantly reduce the amount of CO2 emitted by the transportation sector, automakers and hydrogen fuel suppliers will work together to expand the introduction of FCVs and develop the hydrogen supply network throughout Japan. The two groups are looking to the government to join them in forming various strategies* to support their joint efforts and to gain greater public acceptance of the technology.
*As a specific initiative in the immediate future, the companies plan to approach local governments and other concerned parties to discuss strategies for creating initial consumer demand for FCVs and for the optimal placement of hydrogen fueling stations, targeting Japan's four major metropolitan areas (Tokyo, Nagoya, Osaka and Fukuoka).

Washington State to put quick chargers on scenic byway, allow tourists to top-up their EVs
A few weeks back we learned that the US would be getting 310 quick-charging CHAdeMO stations, 480V AC/DC converters that can get a Nissan Leaf to 80 percent charge in under 30 minutes. Most are destined for major metropolitan areas, but we were intrigued to find out that Washington State is going to put two or three of them out in the country, on a 120 mile scenic portion of Route 2 that runs over the Cascade Mountains. It's a popular tourist destination and, with EVs becoming more popular in the area, soon even tourists with cutting-edge transportation to enjoy the ride. After all, everybody likes a good view.
