Mitsubishi Concept XR-PHEV Evolution Vision Gran Turismo [VIDEO]

Mitsubishi Motors, a company with a spectacular history in races like the Dakar Rally and World Rally Championships (WRC), has developed a special concept model for Vision Gran Turismo: This is the "Mitsubishi Concept XR-PHEV Evolution Vision Gran Turismo".

In the development of this special concept model, Mitsubishi Motors introduced their design team, Advanced Vehicle Research and Development Group, and Aerodynamic Engineering Development Group into this project in the same process they would normally follow to plan and develop real motorsports vehicles.

The styling of the car follows the basic concepts of the "MITSUBISHI Concept XR-PHEV" shown at the 2013 Tokyo Motor Show, while pouring in know-how gained from years of motorsports experience into its every detail. The result was the evolution of the concept into a stoic racing machine.

The "Athlete Form" design concept was advanced further, emphasizing the driving features aggressively. The iconic front grill is a study of next generation Mitsubishi automobiles, and the shape that forms a wedge starting from the triple diamond mark is designed in the image of an athlete at crouching position on a starting line, evoking an intense image of tension and potential.

Utilizing advanced development technology from the Plug-in Hybrid EV System, the spontaneous power of the motor and powerful torque of the engine is transmitted through an 8 speed dual clutch transmission (DCT) to drive the 4 wheels. It's overwhelming drive performance is controlled precisely with the S-AWC vehicle dynamics control system that distributes the drive force optimally to the 4 wheels, producing a handling characteristic that moves the car exactly as the driver desires.

In addition, the carbon fiber reinforced plastic (CFRP) body reduces weight and greatly contributes to its agility, and the downforce produced by the aerodynamic form of the front and rear diffusers produces excellent cornering performance. The large diameter 20 inch aluminum wheels gives an impression of a tough suspension system, and the powerful appearance of the front and rear fenders is in the image of toned muscles of a powerful athlete.

BMW i9 planned for 2016?

Auto Motor und Sport and other German outlets are reporting on BMW’s plans to build an i9 model. Built atop the already sold out i8, the BMW i9 is rumored to be a four-door sportscar.

Little else is known about the i9 but it would presumably feature carbon fiber construction and i8's plug-in hybrid powertrain that consists of a 1.5-liter Turbo three-cylinder engine, an electric motor and a lithium-ion battery which as a combined maximum output of 362 PS (266 kW) and 420 lb-ft (570 Nm) of torque.

BMW has trademarked an entire range of i vehicle, from i1 to i9, with at least one of them, the BMW i5, planned for production in the near future.

Nissan launches GT-R LMP1 WEC and Le Mans programme for 2015

Nissan will take on Audi, Toyota and Porsche in the World Endurance Championship from the start of next season.

Nissan has confirmed that it will mount a two-car attack on the full WEC with a car to be known as the Nissan GT-R LM NISMO.

Nissan vice-president Andy Palmer explained that his company wanted to exploit the new energy-based P1 rules introduced for this season by the Automobile Club de l'Ouest at Le Mans and the FIA.

"We applaud the ACO and FIA for the work they have done to get the rules right," he said.

"LMP1 is not just an arms race - all our rivals in the class have taken different technical approaches and we will be doing the same."

He explained that Nissan wanted "to win in a very different way to that of our rivals".

"We won't be turning up in a vehicle that is a basically another hybrid that looks like another Porsche, Audi or Toyota — they all look the same to me. Our intention is to do something that is a little bit different."

Nissan, which made its announcement in London on Friday afternoon, has yet to disclose technical details of the car or where it will be built.

Volvo to Develop Electric Roads for Dynamic Wireless EV Charging

The Volvo Group is now taking the next step in the development of sustainable transport solutions. In collaboration with the Swedish Transport Administration, the Volvo Group will study the potential for building electric roads, where city buses can be charged from electricity in the road at the same time as the bus is in operation. The benefit is quieter and more climate-smart public transport. A 300- to 500-meter electric road may be built for test operations in central Gothenburg during 2015.

“Vehicles capable of being charged directly from the road during operation could become the next pioneering step in the development towards reduced environmental impact, and this is fully in line with our vision of becoming the world leader in sustainable transport solutions. Close cooperation between society and industry is needed for such a development to be possible and we look forward to investigating the possibilities together with the City of Gothenburg,” says Niklas Gustavsson, Executive Vice President, Corporate Sustainability & Public Affairs of the Volvo Group.

With the use of an electric road, vehicle batteries would continuously be charged wirelessly during operation by transferring energy from the electricity grid to a vehicle, instead of charging the bus while it is standing still at charging stations. The technology being studied is called inductive charging, whereby the energy is transferred wirelessly to the underside of the vehicle by equipment built into the road.

The Volvo Group will develop a detailed proposal within the framework of innovation procurement from the Swedish Transport Administration. The proposal entails building a road section equipped with wireless charge technology and developing vehicles that will automatically charge their batteries when passing such a road section. The road will be built along a suitable bus line in central Gothenburg and be tested for public transport. Experiences from such a test track will provide valuable knowledge for future political and industrial decisions for establishing electric roads.

For several years, the Volvo Group has been offering hybrid buses with a traditional diesel engine that is supplemented by an electrical engine to reduce CO2 emissions. Three Volvo plug-in-hybrid buses are already in operation in Gothenburg (project Hyper Bus*), which charge their batteries at the end stations of line 60. The next stage of development is for these types of buses to be able to charge their batteries while in operation, thus increasing the distance the buses can run on pure electricity. And this is exactly what will be studied now. In 2015, a new bus line, ElectriCity, will become operational between Chalmers and Lindholmen in Gothenburg. This line will also provide additional knowledge of charging technology and electric power for heavy vehicles.

“We are working on both a broad and a deep basis to develop the technology of tomorrow. Electric roads are another important part of the puzzle in our aim of achieving transport solutions that will minimize the impact on the environment,” says Niklas Gustavsson.

Toyota Improve hybrid fuel efficiency by 10% with SiC Inverter

Toyota in collaboration with Denso has developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota will begin test driving vehicles fitted with the new PCUs on public roads in Japan within a year.

Through use of SiC power semiconductors, Toyota aims to improve hybrid vehicle fuel efficiency by 10 percent under the Japanese Ministry of Land, Infrastructure, Transport and Tourism's JC08 test cycle and reduce PCU size by 80 percent compared to current PCUs with silicon-only power semiconductors. SiC power semiconductors have low power loss when switching on and off, allowing for efficient current flow even at higher frequencies. This enables the coil and capacitor, which account for approximately 40 percent of the size of the PCU, to be reduced in size.

PCUs play an important role in hybrids and other vehicles with an electrified powertrain: they supply electrical power from the battery to the motor to control vehicle speed, and also send electricity generated during deceleration to the battery for storage. However, PCUs account for approximately 25 percent of the total electrical power loss in HVs, with an estimated 20 percent of the total loss associated with the power semiconductors alone. Therefore, a key way to improve fuel efficiency is to improve power semiconductor efficiency, specifically by reducing resistance experienced by the passing current. Since launching the “Prius” gasoline-electric HV in 1997, Toyota has been working on in-house development of power semiconductors and on improving HV fuel efficiency.

As SiC enables higher efficiency than silicon alone, Toyota CRDL and Denso began basic research in the 1980s, with Toyota participating from 2007 to jointly develop SiC semiconductors for practical use. Toyota has installed the jointly developed SiC power semiconductors in PCUs for prototype HVs, and test driving on test courses has confirmed a fuel efficiency increase exceeding 5 percent under the JC08 test cycle.

In December last year, Toyota established a clean room for dedicated development of SiC semiconductors at its Hirose Plant, which is a facility for research, development and production of devices such as electronic controllers and semiconductors.

In addition to improved engine and aerodynamic performance, Toyota is positioning high efficiency power semiconductors as a key technology for improving fuel efficiency for HVs and other vehicles with electrified powertrains. Going forward, Toyota will continue to boost development activities aimed at early implementation of SiC power semiconductors.

Toyota will exhibit the technology at the 2014 Automotive Engineering Exposition, to be held from May 21 to May 23 at the Pacifico Yokohama convention center in Yokohama.
