Tesla drops annual servicing for 'as needed' repair model
Tesla has quietly changed its EV maintenance policy, going from regularly scheduled service to an "as-needed" model, according to its "Car Maintenance" page. Before, it called for "recommended" service every 12 months and 12,500 for the Model S and X, and 24 months or 25,000 miles for the Model 3. Now, however, it simply says "your Tesla does not require annual maintenance and regular fluid changes," and instead recommends periodic servicing of things like brake fluid, air conditioning and filters.
Range Rover's 2020 Evoque blends style with sustainability
For the last decade or so, Range Rover has built vehicles more akin to posh living rooms that occasionally go off-roading than the rough and tumble Land Rover Defender 90s of yesteryear. That trend continues with the 2020 Evoque, albeit with a number of innovations that will minimize its environmental impact when you decide to literally go over the fields and through the woods to Grandma's house this holiday.
easyJet's hybrid plane design has a hydrogen fuel cell inside
Aiming to save the European airline money, oh and the environment, easyJet hopes to trial new hybrid plane designs later this year. We're not talking about a new paint job or minor wing design changes, however: the company wants to embed a hydrogen fuel cell into a new hybrid plane design, with aircraft brakes that absorb energy on landing to be reused, even powering the jet through taxiing without using its engines.
Amtrak to roll out high-efficiency trains with regenerative braking (video)
Some of us look at electric trains as efficient transportation almost by definition, but that's not entirely true when they consume a lot of power and give little back. Amtrak is about to strike a better balance now that it's close to receiving the first of 70 high-efficiency Siemens ACS-64 trains destined for routes across DC, Massachusetts, New York and Pennsylvania. Each engine centers on a regenerative braking system that can recover up to 5MW of energy, much of which goes back to the power grid. The machinery is smarter, too: it can self-diagnose problems and mitigate the impact until repairs are possible. Commuters won't immediately notice the difference when ACS-64 trains reach the rails between this fall and 2016, but there should be important behind-the-scenes savings. Amtrak reckons that the new vehicles could lower energy consumption by 3 billion kilowatts in the long run, which might help both the company's bottom line and local utilities.
Land Rover EV prototypes tread lightly uphill, recharge on the way down
Instant torque feels delicious on the highway, but it could be an even bigger asset in an offroader. Land Rover has been experimenting with electric versions of its Defender 110 for a while now, and claims its latest prototypes benefit from a reduction in wheel spin due to the single-speed motor, making them more adept at climbing and less likely to churn up the environment. The prototypes don't necessarily stand out in terms of raw specs: they're 25 percent heavier than turbodiesel models, with lower horsepower and torque ratings, and with a range of just 50 miles. They try to make up for it in other ways, however, with the ability to deliver up to eight hours of slow, grueling off-road time, where range is secondary to staying upright, and by exploiting Land Rover's Hill Descent Control feature for faster recharging through regenerative braking. There's no plan to bring an EV Defender to market any time soon, or to run the Dakar gauntlet like some rivals have, but the prototypes are due to make appearance at the Geneva Motor Show before being tested for painful-sounding "specialist applications" later in the year.
Mazda's i-ELOOP does regenerative braking with capacitors instead of batteries
Mazda has decided there's simply no reason why hybrid cars and EVs should have all of the regenerative braking fun. Its new system, called i-ELOOP, is aimed at traditional internal combustion vehicles. But, rather than rely on batteries, the company turned to capacitors which can be charged and discharged in just seconds. The electricity generated is then fed to the car's various electronic components after being passed through a converter to step down the voltage to 12v. By alleviating some of the burden to generate power from the engine Mazda claims it can increase fuel efficiency by up to ten percent. You won't have to wait long to see this tech make it into your next ride either, the world's first capacitor-based regenerative braking system should be making its retail debut sometime in 2012.

Mercedes-Benz SLS E-Cell prototype fuels our electric dreams with 526 horses
Oh, electric supercar, why do you tease us so? Mercedes is latest to throw up a prototype of what it expects future rubber burners to look like, and its SLS E-Cell doesn't disappoint. Based on its petrol-guzzling SLS AMG model, this beast produces 526 horsepower and 649 pound-feet of torque, thanks to four motors (one for each wheel) allied to a battery array that can provide an industry-leading 480kW of juice. How fast does that get you to the magical 60mph marker? Try four seconds. There's a handsome 10-inch infotainment panel in the center console, which you may see after the break, but the best news is that this prototype can be driven now and could well turn into a production Benz at some point in 2013.
HMK 561 electric bike concept seats you on the battery, makes you significantly more attractive
Most electric bikes are fairly sordid affairs, little more than an ordinary bicycle with a motorized hub, a strap-on battery pack and regenerative braking capabilities (if you're lucky). Not this HMK 561 electric bicycle concept, which took home an iF Design Award for some seriously forward thinking. It's not just the stylish forward rake of this juiced cruiser that's innovative, it's the frame -- composed completely of a conductive carbon fiber weave that allows the bike's body to not just pass electricity to the motors, but actually store it like a giant capacitor. Factor in integrated lights and a pinch of that aforesaid regenerative braking at each axle, and you've just about got the bicycle of our dreams. Oh, and did we mention a prototype has already been built? Yeah. %Gallery-88012%
MIT's Copenhagen Wheel turns your bike into a hybrid, personal trainer
You really can't fault MIT's branding strategy here. Debuting at the biggest climate change conference since Kyoto, its Copenhagen Wheel is a mixture of established technologies with the ambition to make us all a little bit greener and a little bit more smartphone-dependent. On the one hand, it turns your bike into a hybrid -- with energy being collected from regenerative braking and distributed when you need a boost -- but on the other, it also allows you to track usage data with your iPhone, turning the trusty old bike into a nagging personal trainer. The Bluetooth connection can also be used for conveying real time traffic and air quality information, if you care about such things, and Copenhagen's mayor has expressed her interest in promoting these as an alternative commuting method. Production is set to begin next year, but all that gear won't come cheap, as prices for the single wheel are expected to match those of full-sized electric bikes. Video after the break.
Hybrid2 public bike concept promises to help power city buses
Hybrid bikes are one thing, but designer Chiyi Chen looks to have something far grander in mind for his Hybrid2 bike concept, which he says could one day help power fleets of city buses. To do that, the hybrid part of the bike (a regenerative braking system) wouldn't be used to help power the bike itself at all, but would instead store the energy in an ultracapacitor that'd then feed the energy back into the grid when its parked at a special bike stand, which would in turn be used to help charge the hybrid electric buses. Not one to overlook an ingenious little detail, Chen has also devised a special card RFID card that would not only be used to unlock the bike, but keep track of the energy that each rider generates -- build up enough credits and you can ride the bus for free. Intrigued? Head on past the break for a video overview from the man himself.[Via Inhabitat]
Sanyo's eneloop hybrid bike has basket, will travel
Looking for an electric bike that does the pedaling for you? You have plenty of choices, particularly if you're willing to drop over $2,000, but finding one that uses regenerative braking to extend the life of its meager on-board batteries isn't so easy. Panasonic's Vivi RX10S is about your only choice until February, when Sanyo's new eneloop-branded bike is set to start pulling weak (or just lazy) Japanese riders up up inclines before recharging itself on the way back down. On a hilly course a charge is said to last about 35 miles without braking, 46 by charging only when braking, and 62 miles in "auto" mode (charging on downhills, too). If you live in Japan it'll be yours for 136,290 yen, about $1,450 US -- but if you live around here we'd recommend not canceling your spinning class just yet, because while Sanyo pledges to ship this elsewhere in the world "at some point in the future," it could be awhile before this thing starts hitting the diamond lanes near you.[Via PhysOrg.com]
Panasonic's Lithium Vivi RX-10S electric bike does regenerative braking
We're still a bit unconvinced about this whole "using our own energy to induce motion" thing, but if you got restless leg or some other siren call to the bicycle, the Lithium Vivi RX-10S seems the way to go. Panasonic is launching the bike in Japan this August, and stuffed in some fancy hybrid car-style regenerative braking to set it apart from the pack (though Sanyo does have something similar). There are four levels of assistance electric motor assistance, which means you're probably going to end up peddling now and then, but the bike's range with regenerative braking to power a secondary battery is almost 78 miles, compared to 56 miles without it. You'll obviously benefit more if you have a lot of hills and "stop and go" type stuff on your commute, but that's certainly nothing to scoff at.
