Ford launches innovate mobility challenge series
July 16, 2014
Ford launched its Innovate Mobility Challenge Series, inviting the developer and maker communities to come together to find innovative mobility solutions in eight different locations around the world. The worldwide challenges kicked off in Lisbon, Portugal; Los Angeles, United States; and Mumbai, India; before moving on to Delhi and the Chennai region in India; Shanghai, China; Johannesburg, South Africa; and a countrywide challenge in Argentina.
For each competition, Ford will partner with local authorities and experts to address different issues in each location. The competitions will be judged by a panel of Ford executives involved in researching mobility solutions, as well as by local experts selected for each competition.
DENSO develops a new low-cost fuel injection system for small motorcycles

Global automotive supplier DENSO Corporation has developed a new electronic fuel injection system for small motorcycles called DIET-FI (DENSO Intelligent Economical Technology-Fuel Injection). DIET-FI is the first fuel injection system that doesn’t use a throttle position sensor or engine temperature sensor. Rather, it uses newly developed control technologies that ensure the same fuel economy and environmental performance as conventional fuel injection systems, thus cutting costs.
In the two-wheeler segment, fuel injection systems are usually only used in motorcycles; however, in recent years there has been a growing need to apply these systems to smaller motorized bikes up to the size of 150cc that are used in emerging markets, such as China.
Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters
May 23, 2014
A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes. The study by the team led by researchers from the Laboratory of Atmospheric Chemistry, Paul Scherrer Institute, Switzerland, appears in the journal Nature Communications.
The team calls 2S scooters “asymmetric polluters” as their emission factors (EFs) and evidence from air quality measurements before and after bans on scooters in Asian cities suggest they may dominate vehicular pollution despite their relatively small numbers.

A start-up is bringing the old Bultaco motorcycle brand back to the market with the planned launch of a line of electric two-wheelers. The new company unveiled the Rapitán and Rapitán Sport prototypes—close approximations to the Bultaco motorcycles that will be brought to market later in 2014.
The Rapitán & Rapitán Sport will be powered by a 40 kW air-cooled brushless induction motor delivering 125 N·m (92 lb-ft) of torque, and a Li-ion battery-based energy storage system. Maximum speed is 145 km/h (90 mph) and expected range is 200 km (124 miles) in the city; 110 km (68 miles) on the highway; and 140 km (87 miles) combined.
Bosch offering range of complete powertrains for two-wheelers; Asia and smartphones
May 08, 2014
Bosch is entering the global market for two-wheeler powertrains with its own range of complete systems. The company has developed an electronically controlled fuel injection system that can be adapted to any vehicle—allowing Bosch to offer solutions ranging from the cheapest single-cylinder two-wheeler in Asia to the high-performance bikes prevalent in Europe and North America.
Bosch regards the two-wheeler segment as one of the growth markets of the future and expects worldwide sales of motorcycles to reach around 150 million units in 2020, more than the equivalent figure for cars. Just as it is for cars, Asia is a driver of growth in the two-wheeler segment. Up to now, Bosch’s presence in the two-wheeler segment has revolved chiefly around automotive components modified for use in high-performance motorcycles.
BMW Motorrad’s electric C evolution

BMW Motorrad is launching its battery-electric C evolution maxi scooter. (Earlier post.) Its two conventionally powered maxi scooter model—C 600 Sport and C 650 GT—combine the ride qualities of a motorcycle with the specific agility and comfort of a scooter; the C evolution adds the dynamism and emissions-free operation of an electric vehicle.
The C evolution is powered by a drivetrain swing arm with liquid-cooled permanent magnet synchronous motor via a toothed belt and ring gearing. The rated power output is 11 kW (15 hp), with a peak output of 35 kW (47 hp); maximum torque is 72 N·m (53 lb-ft). This enables the C evolution to achieve a top speed of 120 km/h (75 mph, electronically limited) and gives it better acceleration than some maxi scooters powered by engines with displacements of 600 cc or more.
US PIRG report finds reduced driving and rates of car commuting in most populous US urbanized areas

A new report by the US PIRG Education Fund and the Frontier Group details reduced driving miles and rates of car commuting in the US’ most populous urbanized areas, as well as greater use of public transit and biking in most cities. The average American drives 7.6% fewer miles today than when per-capita driving peaked in 2004.
The report, “Transportation in Transition: A Look at Changing Travel Patterns in America’s Biggest Cities,” is based on the most current available government data and is, according to US PIRG, the first national study to compare transportation trends for America’s largest cities and lists results for each. Among the report’s national findings:
SAE New Energy Vehicle Forum: China’s focus on NEVs may have profound impact on future of transportation
November 13, 2013
China has a number of critical economic and environmental imperatives driving its pursuit of vehicle electrification, said the roster of plenary speakers at the SAE 2013 New Energy Vehicle Forum held in Shanghai this week. These include the increasingly problematic pollution and haze in cities; China’s projected increased reliance on imported oil; the need for rationalized multimodal transportation systems in ever more congested and space-limited cities; the growing dominance of the China auto market; and the desire to have China become the leader in the next generation of automotive technology, vehicles and mobility systems.
The shift from fossil fuels to electricity—while held in common with other countries—will be based on the “specific situation” in China, making the best use of China’s own advantages and innovations, but also with international cooperation, said Dr. Zhixin Wu, Vice President of the China Automotive Technology and Research Center (CATARC). The details of that specific situation may result in an electric vehicle parc somewhat different than in Western countries, other speakers noted, and may indeed—given the obvious scale of the China market—herald a major transformation in transportation, including the type and role of personal vehicles, others suggested.

Toyota confirmed that it will display its latest fuel cell vehicle concept along with four other world premiere future mobility concepts at the upcoming Tokyo Motor Show. The Toyota FCV Concept is a practical concept of the fuel cell vehicle Toyota plans to launch around 2015 as a pioneer in the development of hydrogen-powered vehicles. The vehicle has a driving range of at least 500 km (311 miles) and refueling times as low as three minutes, roughly the same time as for a gasoline vehicle.
The Toyota FC Stack has a power output density of 3 kW/L, more than twice that of the current “Toyota FCHV-adv” FC Stack, and an output of at least 100 kW. In addition, the FC system is equipped with Toyota’s high-efficiency boost converter. Increasing the voltage has made it possible to reduce the size of the motor and the number of fuel cells, leading to a smaller system offering enhanced performance at reduced cost.

Although still a nascent market in most regions of the world, electric scooters sell in significant numbers in Asia Pacific today, according to Navigant Research. Sales of e-scooters in China alone are expected to reach 9.4 million in 2013, compared to 2.6 million in all other countries combined. Sales in regions outside of Asia Pacific are estimated at 31,338 vehicles in 2013, Navigant said.
