Electric 1967 Karmann Ghia runs on social-media fuel

Back when a certain 1967 Karmann Ghia rolled off the assembly line, nobody could have expected that one day it would be gutted, filled with batteries, and turned into an electric car that runs thanks to social-media feedback. The car is part of the Minddrive after-school program, a Kansas City (both Missouri and Kansas) organization dedicated to working with at-risk students.

For Minddrive’s latest automotive design project, students chose to refurbish an old Karmann Ghia, turning it into an electric
car. The car will be driven from Missouri to Washington D.C. starting on May 31, but it will take a lot of help to get it there. The car is designed to run only if there is enough social-media support to keep it going.

A device in the car logs the number of Minddrive tweets, shares, video plays, and Facebook mentions the group gets. Those numbers are used to determine how much “fuel” the electric batteries have. With no social-media feedback at all, the car wouldn’t run an inch. However, the social-media campaign is well under way. You can follow the current tallies at Minddrive’s site.

Each Twitter follow is worth 5 watts. Each Facebook like is worth 1 watt. Each petition signature to support learning organizations like Minddrive is worth a whopping 10 watts.

The Karmann Ghia can go about 30 miles on a charge and has a top speed of 45 mph. It will take about a week to reach its road trip destination.

Besides converting the original Karmann Ghia, the students are also working on creating copies with sustainable wood structures and fiberglass bodies. These cars are designed to be produced at the rate of one per month and sold as kits to the public, with the funds going to continued support of Minddrive. These models won’t have the social-media requirement, so you won’t have to be Internet-famous to run them.

RC car transforms into a quadcopter

If Chitty Chitty Bang Bang were made now, it would probably look a bit more like something Batman or James Bond would drive, but we’d like to think it would look a little more like this.

Called simply “B,” the toy, which is currently being funded on Kickstarter, is the creation of U.K. computational-engineering PhD student Witold Mielniczek. Unlike other remote-controlled toys out there, it’s also a multitalented piece of gadgetry that’s able to traverse both ground and sky.

Most quadcopters we’ve seen to date have four “wheels” at the corners, horizontally aligned with helicopter blades spinning inside. Mielniczek has tilted the wheels upright — and made them functional for ground-based driving.

It has vertical take-off and landing, transitioning on the move and an on-board 1,280x720p camera on-board for recording as it goes — and it can go fast. But what happens when it crashes, as it inevitably does? Well, with a body shell built of polycarbonate, the material used in protective goggles and riot shields, it’s built to take a beating.

“The chassis when combined with the body shell not only forms a rigid and light construction that maintains its shape when flying or driving, but is also flexible enough to absorb excessive forces generated during crash landings,” Mielniczek said. And the blades are protected, too: “The wheels naturally guard the blades around them. If an impact occurs on the side of the vehicle, the prop saver will protect the blades.”

It only has enough battery life for 15 minutes of action on full charge, but Mielniczek doesn’t see this as a problem. “Could B fly for 25 to 30 minutes? … Yes, with carbon fiber body and custom-made propellers, top-end electronic components, etc., but the model would cost three to five times more! I do not believe anyone would like to spend that much for extra 10 minutes of fun,” he said.

The thing looks slick, and seems to work brilliantly. You can see it in action in the video below, starting at around 50 seconds. It’s a little on the pricy side, starting at 125 British pounds (around $188) for just the
car, with the ability to upgrade in the future. An assembly kit for the flying version is about $482, and the full monty comes in at about $600 — but Mielniczek is dreaming big.

“If B becomes a commercial success, I want to reinvest to use B as a way to help people,” he said. “You never know; one day, I may even be able to live out my ultimate dream and make a life-sized model that can carry people!”

GM exec: Apps coming to select cars later this year

LAS VEGAS — General Motors is eager to get its slice of the app pie.

Mary Chan, head of the global connected consumer unit for GM, told CNET that apps would come to select
cars in the second half. The initial set of apps will be per-determined by the company, will be available for download, and will make up the early stages of its in-car app store. More importantly, GM will also debut an app framework in these cars that will enable the download of future apps.

With the proliferation of the app market in mobile devices, GM — and several others in the auto industry — want to get in on the action. Rather than let smartphones power apps in the car, GM is pushing to get more apps built specifically for its cars, which Chan says creates an easier and safer experience for the driver because it’s integrated.

“We don’t want the auto industry shying away from apps and pushing it all to the device makers,” Chan told CNET on Tuesday.

GM declined to comment on which models would get the apps, but they will be cars from the 2014 line-up (which debuts later this year). Chan said the system is flexible enough so that the cars with early access to apps will be able to access additional apps when more become available. GM will determine the initial set of apps that drivers will be able to access.

GM is still working out the details of the business. Chan said the apps may be free, bundled into a service that GM charges for, or paid out to the developers. Another possibility, a subscription paid for an app on the smartphone could be applied to a separate app in the car. The company is looking at different business models right now.

But GM has attracted a small following of developers since it opened up its software development kit and application programming interface in January. Since then, 1,800 developers have signed up, with a mix of well-known companies and smaller independent programmers. Chan said the developers are attracted by the opportunity of an entirely new market with a potentially large base of customers.

GM followed up with its developer outreach with an announcement in February to partner with ATT to introduce cars with 4G LTE capabilities. GM has committed to bringing out millions of connected cars in late 2014.

GM itself plans to build its own set of apps, such as diagnostic programs or other apps specifically built to monitor the car itself, Chan said. She said it was important for GM to work with developers on their apps because they need to be tweaked so they won’t distract the driver. Apple’s Siri, for example, works with select GM cars but had to be stripped of some capabilities because they were deemed too dangerous or distracting.

“We want to make the experience better,” she said.

Aston Martin reveals Batmobile-like anniversary speedster

It looks strangely like something Adam West’s Batman might drive in 2013, but Aston Martin’s 100th anniversary CC100 speedster wasn’t designed with superheroes in mind, camp or otherwise. Instead, the yellow-and-blue-gray speedster is an homage to the company’s heritage as a manufacturer of luxury sports cars.

The design is based on the 1959 Le Mans and Nurburgring-winning DBR1, with materials and design elements that look to the future, according to the company. “CC100 is the epitome of everything that is great about Aston Martin. Fantastic heritage, exceptional design, superb engineering and an adventurous spirit,” Aston Martin CEO Ulrich Bez said.

With no cover, it certainly wouldn’t be of any use as a day-to-day
car, but as it was designed as a concept and remains one, we don’t think Batman would have to worry about getting his ‘do messed up.

The new Pathfinder mixes SUV and minivan capabilities

Nissan’s Pathfinder started life as a truck-based SUV, then went to unibody construction in a subsequent generation, becoming a crossover before there were crossovers. That generation was followed by a truck-based model, which gained a little off-road cred. With the 2013 Nissan Pathfinder the pendulum swings back to a crossover design, striving to retain its backcountry capability while adding all the comforts of a minivan. With the Platinum Premium package, Nissan even throws in a rear-seat entertainment system.

What Nissan really attempts with the Pathfinder is to be all things to all people. This effort is, for the most part, successful.

The Pathfinder offers three-row seating, with a middle row that slides forward to allow easy rear-seat access, making it a capable people carrier. Middle-row and rear seats all fold down mostly flat, creating a good amount of cargo space for those weekend IKEA runs. The aforementioned rear-seat entertainment system keeps the kiddies quiet on road trips, while Nissan packs the dashboard with its standard kit of cabin electronics for navigation, audio, and phone. More ambitiously, the Pathfinder boasts a four-wheel-drive system featuring differential-locking capability.

Although the Pathfinder is equipped with a continuously variable transmission, Nissan rates its towing capacity at 5,000 pounds, more than enough to pull a Sea Ray 21 Jet speedboat.

The front seating area of the Pathfinder reads more like a minivan, with beige leather power-adjustable seats and a rounded dashboard, than an SUV. The driving position is not particularly high, making access easy. The interior design highlights softness and comfort more than rugged utility.

Old, familiar electronics
Greeting me in the center dashboard was an old friend, Nissan’s stock navigation system. I have always found Nissan’s cabin electronics interface to be very usable, with its odd combination of a touch screen and dial controller. The dial, with directional buttons mounted on top, works very well for zipping through onscreen menus. When it comes time to use the onscreen keyboard, I go to the direct input of the touch screen.

The Pathfinder has a hard drive for navigation map storage, making screen inputs and map refresh quick. The maps also show traffic flow and include rendered building images in downtown areas. Route guidance, with its graphics and voice prompts, was easy to follow. Using voice recognition to enter addresses proved tedious, as I had to enter each part separately. I found I could enter addresses more quickly using the dial and touch screen.

Zagat ratings for restaurants can direct you to a good place to eat.

Included in the points-of-interest database were Zagat-rated restaurants, a nice addition, but the system did not show me the nearest restaurants, instead making me scroll through a long list of cities.

The Pathfinder also pulls in a weather forecast with this system, delivered through its satellite radio channel, but there is no app integration of any sort.

In the Pathfinder, Nissan restricts this navigation system to the Platinum trim. You can’t get it on S, SV, or SL models, not even as an option. And with navigation comes other niceties such as Bluetooth audio streaming.

A Bluetooth phone system, however, comes standard in all but the lowest trim. In the Pathfinder Platinum, that system featured an onscreen interface giving access to my paired phone’s contact list and a second contact list saved to the car. The phone system allowed dial-by-name through voice command.

Advanced transmission
All Pathfinders use the same drivetrain, based on a garden-variety 3.5-liter V-6 and the previously mentioned continuously variable transmission (CVT). The engine’s output, at 260 horsepower and 240 pound-feet of torque, sounds unremarkable. Nissan almost seems to deemphasize the engine, hiding the tailpipe behind the rear fascia under the Pathfinder.

Given Nissan’s excellent CVT, the engine can afford to be average. CVTs use a set of bands and spools to constantly find the optimum drive ratio between engine and wheels. Nissan has been refining this one for many years, and the work shows.

A CVT may seem weak for an SUV, but the Pathfinder’s felt solid and gave it a good driving character.

As I drove over freeways, city streets, and narrow highways, the CVT ensured that I always had available power on tap. The Pathfinder accelerated smoothly, with no gear dumps. When I needed to pick up speed fast, the CVT readily dropped to a lower drive ratio, pulling more power from the engine. There were never any of those flat spots you get with fixed gears, never any waiting for the engine to catch up with a new gear ratio.

The CVT also gave the Pathfinder a very easy driving character. Rather than with an engaged driving experience, the Pathfinder honors its crossover status with get-in-and-go drivability. Although I did have to wait a few moment for the navigation system to boot up before I could enter an address.

My iPhone 5’s got a V-8

Gasket V8

Id America’s Gasket V8 case comes in five colors, those shown here plus red and yellow.

Josh Miller/CNET)

For the last week, my iPhone has been sporting a case designed to look like an engine’s head gasket. The maker, Id America, calls it a V-8, but as I’ve only got one phone, it’s a four-banger.

The Gasket V8 case, as Id America calls it, is a nice variation on the competition, usually plastic or rubber with decorations consisting of simple prints and decals. This one is made of metal stamped through with four cylinder holes and apertures for cooling, oil, and bolts.

For variation, it comes in silver, charcoal, red, yellow, or blue. You will have to add your own grease.

A soft material coating the inside keeps it from scratching the phone and provides a little shock protection. Installation is a simple matter of snapping the phone in between the sides, no torque wrench required.

For those prone to dropping phones, the Gasket V8 case doesn’t offer a lot of protection. It shields the back and sides, but leaves the ends and face completely uncovered. Id America includes a clear plastic screen cover, but it has a big logo reading “Born in New York” down one side, which I didn’t really want on my phone.

The plus side of the open design is that the iPhone’s ports and buttons remain easy to access.

I like the feel of the Gasket V8 case better than the thin plastic case I had previously used. The rounded case edges rest comfortably in my hand, although I had to get used to slightly more bulk.

The best thing, of course, is the look of the case. With
cars so much more reliable these days, and subsequently fewer shade-tree mechanics, few people recognize a head gasket. So the case serves as a kind of secret handshake for gearheads.

Id America also makes a V-6-based gasket case for the
iPhone 4/4S.

The Gasket V8 case for the
iPhone 5 is available from Id America’s Web site for $29.95.
