Charged with Electric Vehicle News and Views
Toyota's i-ROAD compact electric personal mobility vehicle takes to the streets in Japan's capital.
Participants in the limited public trials share their feedback on the ultra-compact, fun to drive i-ROAD, which is available in five colors.
Norwegian Tesla owner Bjørn Nyland has uploaded a video demonstrating his Model S at Autobahn speeds.
A Tesla Model S P85 driven at it's maximum speed of 210 km/h (130 mph) has an estimated range of 154 kms (96 Miles)
Having recently returned from Munich I can vouch for the fact that driving at 160 km/h (100 mph) in the fast lane is considered slow, they really do drive at 200 km/h routinely on unlimited sections, yet the road toll is actually lower than in many other countries (including Australia).

Continental has taken the Conti.eContact that was originally launched in 2011 with electric vehicles in mind and refined it to meet the needs of hybrid models. Thanks to the introduction of numerous new technologies and processes, this new and extensively hand-crafted summer tire is the first from Continental to obtain the top A rating on the EU Tire Label for both wet grip and rolling resistance, while making no significant compromises in terms of the many other performance parameters.
With immediate effect Continental is offering the Conti.eContact in six sizes for 17 and 18-inch rims, specially designed for models such as the Opel Ampera, BMW 5 ActiveHybrid, Lexus LS 600h and Porsche Cayenne S Hybrid, as well as other cars and SUVs with hybrid drive. Given that this is a new vehicle segment that also involves highly complex production processes, Continental is kicking off with low-volume production at its French tire plant in Sarreguemines.
The rolling resistance of the new Conti.eContact for hybrid vehicles is some 20 percent lower than in a conventional tire, while delivering a wet braking performance similar to that of a normal car tire. This is made possible by a combination of advanced technologies in the development, compounding and production sectors. In terms of handling and braking on dry roads, the tire performs at the same high level as a Continental sedan tire of comparable size. As a member of the Continental tire family for hybrid and electric vehicles, the Conti.eContact bears the “BlueEco” logo on the sidewall. Continental’s in-house studies point to incremental growth in the proportion of hybrid vehicles in the passenger car segment, which could account for as much as eight percent by 2020.
Green Chili compound
Featuring the newly developed Green Chili compound, the silica compound of the new Conti.eContact for hybrid vehicles is made up in such a way that the internal friction of the filler particles and the polymers is lower than in conventional rubber compounds. The use of special additives provides an additional boost in terms of handling properties. With this new compound, the chemists at Continental have achieved a marked reduction in rolling resistance, while maintaining a high level of handling and braking performance on dry roads.
Hydro-sipes
On wet roads the specially configured twin sipes in the tread blocks generate a ‘windshield wiper’ effect that breaks up the film of water under the contact patch. This smart thinking by the tread designers at Continental enables the water between the surface of the tread blocks and the road to be rapidly dispersed, making for very short stopping distances in the wet. The fast dispersion of the water also benefits the tire’s wet handling – even at higher speeds. The tread design makes a valuable contribution to the short stopping distances in the wet that led to the Conti.eContact’s A rating for wet grip on the EU Tire Label.
AeroFlex technologyAlong with the new technologies adopted for the compound and tread design, the sidewalls of the new Conti.eContact have also been redesigned. In this case the tire designers focused on minimizing aerodynamic drag and rolling resistance. This they achieved through the aerodynamically modified sidewall and its flexible, lightweight design. As a result, in the new Conti.eContact less energy is lost when the tire deflects and rebounds than in a conventional tire. In addition, the drop in turbulence has led to a further reduction in the tire’s contribution to fuel consumption.
ContiSilent
When hybrid vehicles run in electric mode they are virtually silent. As tire noise is no longer drowned out by other sources of noise such as a conventional engine, it is all the more noticeable. Consequently, the new Conti.eContact is designed to generate minimum audible noise in the vehicle interior. This is achieved with the aid of ContiSilent technology. A thin layer of polyurethane foam attached to the inside of the tread reduces the vibrations that are generated as the tire rolls along the road. This means that less vibration is communicated to the chassis, leading to a lower level of noise in the cabin.
Innovation, meet heritage. Today, Harley-Davidson reveals Project LiveWire – the first Harley-Davidson® electric motorcycle.
In keeping with the company's customer-led product development approach, starting next week select consumers across the country will be able to ride and provide feedback on the bike, helping to shape the future of Harley-Davidson's first-ever electric motorcycle.
While not for sale, Project LiveWire is specifically designed for the purpose of getting insight into rider expectations of an electric Harley-Davidson motorcycle.
"America at its best has always been about reinvention," said Matt Levatich, President and Chief Operating Officer, Harley-Davidson Motor Company. "And, like America, Harley-Davidson has reinvented itself many times in our history, with customers leading us every step of the way. Project LiveWire is another exciting, customer-led moment in our history."
Spurred by this heritage, the Project LiveWire Experience invites customers to test ride, provide feedback and learn more about the story of the motorcycle. Even those who don't yet ride will have the opportunity to feel the power of Project LiveWire through Jumpstart – a simulated riding experience.
A 2014 U.S. tour – kicking off with a journey down Route 66 – will visit more than 30 Harley-Davidson dealerships now through the end of the year. In 2015, the Project LiveWire Experience will continue in the U.S. and expand into Canada and Europe.
"This builds on many recent reinvention successes for Harley-Davidson," said Levatich. "In just the last few years, we've broadened our reach to serve an increasingly diverse society, as well as reinvented our approach to product development and manufacturing. This has resulted in cutting-edge products like the recently launched Project Rushmore touring bikes, Harley-Davidson Street 500 and 750 models and this reveal of Project LiveWire."
An Innovative Approach to Advance the Possibilities of Personal Freedom This exciting new ride blends the company's styling heritage with the latest technology to deliver a new expression of the signature Harley-Davidson look, sound and feel.
"Project LiveWire is more like the first electric guitar – not an electric car," said Mark-Hans Richer, Senior Vice President and Chief Marketing Officer, Harley-Davidson Motor Company. "It's an expression of individuality and iconic style that just happens to be electric. Project LiveWire is a bold statement for us as a company and a brand."
The bike offers a visceral riding experience with tire-shredding acceleration and an unmistakable new sound.
"The sound is a distinct part of the thrill," said Richer. "Think fighter jet on an aircraft carrier. Project LiveWire's unique sound was designed to differentiate it from internal combustion and other electric motorcycles on the market."
Longer term plans for retail availability of Project LiveWire will be influenced by feedback from riders along the Project Livewire Experience tour.
"We offer a no excuses riding experience in everything we do and we are led by what our customers tell us matters most," said Richer. "Because electric vehicle technology is evolving rapidly, we are excited to learn more from riders through the Project LiveWire Experience to fully understand the definition of success in this market as the technology continues to evolve."
Helping Preserve and Renew the Freedom to Ride for Generations As riding in the great outdoors is one of the best elements of motorcycling, sustainability remains a core strategic focus at Harley-Davidson.
"Preserving the riding environment is important to all of us," said Levatich. "Project LiveWire is just one element in our efforts to preserve and renew the freedom to ride for generations to come. As a company that has seen success for 111 years, we think in generational terms about our great riding environments for the next 111 years."
Racing group Team TAISAN and materials engineer Power Japan Plus have formed a partnership to develop an electric racing vehicle, which will be the first in the world to use the Ryden dual carbon battery.
Under this partnership, Power Japan Plus will provide Ryden cells and Team TAISAN will leverage its vast experience in international racing to optimize the battery and develop a battery pack and management circuit. A go-kart powered by the Ryden dual carbon battery will begin test driving August of this year.
“We have faced a number of issues with electric vehicle batteries up until now. The Ryden battery from Power Japan Plus is the solution we have been searching for,” said Yasutsune Chiba, owner of Team TAISAN. “We will first develop a battery capable of withstanding the rigorous demands of racing, before advancing the technology for use in commercial applications."
Team TAISAN has faced many roadblocks with conventional battery technology, the danger of thermal runaway being the most prevalent. Intense heating prevented other electric vehicle (a Tesla Roadster) racing cars used by TAISAN from running continuously. In searching for a solution to this problem, Team TAISAN discovered the Ryden dual carbon battery developed by Power Japan Plus.
The Ryden dual carbon battery wields an energy density comparable to lithium-ion batteries, with a much faster charge time. In addition, Ryden is resistant to heating during operation, mitigating the threat of thermal runway and yielding a simpler battery pack cooling system.
"Team TAISAN has profound experience in automotive technology, especially with the high demand world of motorsports,” said Dou Kani, CEO and co-founder of Power Japan Plus. “I am confident that by working together with Team TAISAN, we can produce an irreplaceable electric vehicle battery unlike any ever made.”
Development will start with a go-kart powered by the Ryden dual carbon battery, which will undergo endurance testing in harsh summer heat conditions this August. The team will then build a full scale EV racing car driven by a Ryden battery pack. Team TAISAN will conduct endurance and safety tests on the electric racing vehicle at its facilities in Chiba Prefecture, Japan, with a goal for the vehicle to debut in a Japanese EV racing competition.
Established in 1983, Team TAISAN is recognized as one of Japan’s most prestigious racing teams, with a total count of 72 victories. Among these victories, Team TAISAN has won 13 Japanese national racing championships – eight during the last 20 years – at the All Japan Grand Touring Car Championship (JGTC) / Super GT (SGT). The team has also won six overseas championships, including The 24 Hours of Le Mans in the GT class in its very first attempt, going on to complete the race a total of six times. The team has also been actively involved in EV endurance racing in Japan. Team TAISAN was an early adopter of the Tesla Roadster, champion at the 2011 ALL JAPAN EV-GP SERIES, as well as the modified EV Porsche 916 model, which completed four, one-hour endurance races hosted by the EV Club, with third place honors in the lead-based battery class.
The partnership was announced publically prior to the start of the 24 Hours of Le Mans race this past Saturday in Le Mans, France.
Nissan's ZEOD RC has recorded the highest ever speed by an electric vehicle at Le Mans with Japanese ace Satoshi Motoyama reaching 300km/h on the Mulsanne Straight in qualifying for the Le Mans 24 Hours.
Motoyama reached the speed on his electric run, achieving one the key goals of the unique prototype which features a dual electric/internal combustion engine powertrain featuring a pair of 110kW electric motors along with a remarkable 40 kg, 400 horsepower 1.5 liter three-cylinder turbo engine.
The ZEOD (zero emissions on demand) permits the driver to switch back and forth between the two power sources.
Motoyama achieved the target on his first run in the car after he missed out on driving on Wednesday night to a gearbox issue in the first session and a series of session-stopping red flags during the night.
"I drove ZEOD at Le Mans for the first time and instantly we were able to reach our target to run at more than 300km/h with electric power only," Motoyama said.
"I was so surprised with the speed and power of electricity and it felt great. In yesterday’s session we had some trouble with the gearbox in the first session then we had a heap of red flag periods and I didn’t get the chance to get into the car.
"But the guys on the team did a great job to fix the car and I and I was able to get started tonight right at the green flag tonight.
“Our first target of the top speed of 300 km/h with electric power is done and I think that was a really good first step."
Motoyama along with GT Academy winners Lucas Ordóñez and Wolfgang Reip all drove multiple stints aboard the ZEOD tonight - each recording their mandatory five night laps.
The Nissan ZEOD RC competes at Le Mans this week in "Garage 56" - an additional entry for vehicles showcasing new and innovative technology.
Car and Driver gathered five slippery cars to study their drag and lift properties at a wind tunnel to determine which brand did the best job optimizing its car’s aero performance.
The overall winner was the Tesla Model S by virtue of its larger 25.2-square-foot face and lower 0.24 drag coefficient, which yield the same 6.2-square-foot drag area as the Prius. Low drag is a tougher challenge with a larger frontal area, hence the Tesla’s overall win.
