GM EN-V Concept, 2010


 
 
 
 
By 2030, urban areas will be home to more than 60 percent of the world's 8 billion people. This will put tremendous pressure on a public infrastructure that is already struggling to meet the growing demand for transportation and basic services.

General Motors and its strategic partner, Shanghai Automotive Industry Corp. Group (SAIC), share a common vision for addressing the need for personal mobility through a radical change in personal urban transportation. They are exploring several solutions for tomorrow's drivers. Among the most promising is a new vehicle form called EN-V.

A Promising Solution
EN-V, which is short for Electric Networked-Vehicle, maintains the core principle of personal mobility - freedom - while helping remove the motor vehicle from the environmental debate and redefining design leadership. EN-V is a two-seat electric vehicle that was designed to alleviate concerns surrounding traffic congestion, parking availability, air quality and affordability for tomorrow's cities.

Three EN-V models were unveiled in Shanghai. They represent three different characteristics that emphasize the enjoyable nature of future transportation: Jiao (Pride), Miao (Magic) and Xiao (Laugh). The concepts will be showcased from May 1 through October 31 at the SAIC-GM Pavilion at World Expo 2010 Shanghai. Shanghai is expected to become one of the epicenters for the establishment of personal mobility solutions for the future.

Breakthrough Technology
GM EN-V Concept's platform has evolved from the platform of the Personal Urban Mobility and Accessibility (P.U.M.A.) prototype that was developed by Segway and debuted in April 2009. Segway has worked collaboratively with GM to develop and deliver multiple copies of the drivetrain platform that seamlessly connect to and power the various EN-Vs.

GM EN-V Concept is propelled by electric motors in each of its two driving-mode wheels. Dynamic stabilization technology empowers EN-V, giving it the unique ability to carry two passengers and light cargo in a footprint that's about a third of a traditional vehicle. It can literally "turn on a dime" within its own operating envelope. In addition, everything in EN-V is drive-by-wire, supporting its ability to operate autonomously or under manual control. The motors not only provide power for acceleration, but also bring the vehicle to a stop.

Power for the motors is provided by lithium-ion batteries that produce zero emissions. Recharging can occur from a conventional wall outlet using standard household power, allowing EN-V to travel at least 40 kilometers on a single charge. EN-V can also improve the efficiency of the public electric infrastructure since the vehicle can communicate with the electric grid to determine the best time to recharge based on overall usage.

By combining the Global Positioning System (GPS) with vehicle-to-vehicle communications and distance-sensing technologies, the EN-V concept can be driven both manually and autonomously.

Its autonomous operating capability offers the promise of reducing traffic congestion by allowing EN-V to automatically select the fastest route based on real-time traffic information. The concept also leverages wireless communications to enable a "social network" that can be used by drivers and occupants to communicate with friends or business associates while on the go.

This combination of sensing technology, wireless communication and GPS-based navigation establishes a technology foundation, pieces of which could migrate from the EN-V concept and potentially lead the way to future advanced vehicle safety systems.

The ability to communicate with other vehicles and with the infrastructure could dramatically reduce the number of vehicle accidents. Using vehicle-based sensor and camera systems, EN-V can "sense" what's around it, allowing the vehicle to react quickly to obstacles or changes in driving conditions. For example, if a pedestrian steps out in front of the vehicle, EN-V will decelerate to a slower and safer speed and stop sooner than today's vehicles.

GM has been a leader in developing autonomous vehicle technology, having worked alongside students and faculty at Carnegie Mellon University in the U.S. city of Pittsburgh, Pennsylvania. This collaboration created "The Boss" Chevrolet Tahoe, which brought autonomous vehicle operation to life in 2007. EN-V takes the lessons learned in "The Boss" and offers mobility to people who could not otherwise operate a vehicle.

"The EN-V concept represents a major breakthrough in the research that GM has been doing to bring vehicle autonomy to life," said Alan Taub, Global Vice President of GM Research and Development. "The building blocks that enable the autonomous capabilities found on the EN-V concept such as lane departure warning, blind zone detection and adaptive cruise control are being used in some GM vehicles on the road today."

GM EN-V Concept has been designed for the speed and range of today's urban drivers. It weighs less than 500 kilograms and is about 1.5 meters in length. By comparison, today's typical automobile weighs more than 1,500 kilograms and is three times as long. In addition, today's automobiles require more than 10 square meters of parking space and are parked more than 90 percent of the time. EN-V's smaller size and greater maneuverability mean the same parking lot can accommodate five times as many EN-Vs as typical automobiles.

Smaller, Smarter Design
While EN-V leads the way in terms of efficiency and technology, it also sets a new benchmark for vehicle design. For its debut, GM had design teams around the world provide their vision of what future mobility will look like. Xiao (Laugh) was designed by GM Holden's design team in Australia, while the look of Jiao (Pride) was penned by designers at GM Europe and Miao (Magic) was designed at the General Motors Advanced Design Studio in the U.S. state of California.

Each EN-V has a unique design theme to showcase the flexibility of the propulsion platform. The design gives each EN-V its own personality, with a unique opening, elegant interior and innovative color, lighting and seat technology. Xiao offers a more lighthearted appeal, with its "gumball blue" paint and nautical-inspired design. Miao takes most of its design cues from the consumer electronics industry, as evidenced by its sleek, masculine looks. Designers also used Miao to display innovative lighting solutions, including extensive use of LED accent lighting. With its clean lines and bright paintwork, Jiao takes its design influence from bullet trains and Chinese opera masks.

The body and canopy of GM EN-V Concept are constructed from carbon fiber, custom-tinted Lexan and acrylic, materials that are more commonly used in race cars, military airplanes and spacecraft because of their strength and lightweight characteristics. The ability to work with such innovative materials provided a learning opportunity for GM's design teams to study the feasibility of future traditional automotive applications.

EN-V's compact size makes it ideal for use in densely populated cities thanks to its use of advanced safety and propulsion technologies. But good things come in small packages, as witnessed by EN-V's innovative interior design, which provides maximum visibility to the world outside. A simple interface for activating Wi-Fi-based technologies keeps occupants connected to the outside world.

GM PUMA Concept, 2009


 
Dubbed Project P.U.M.A. (Personal Urban Mobility and Accessibility), GM and Segway are developing an electrically powered, two-seat prototype vehicle that has only two wheels. It could allow people to travel around cities more quickly, safely, quietly and cleanly - and at a lower total cost. The vehicle also enables design creativity, fashion, fun and social networking.

GM and Segway announced their collaboration, while demonstrating the Project P.U.M.A. prototype in New York City.

Trends indicate that urbanization is growing, and with that comes increased congestion and more competition for parking. Cities around the world are actively looking for solutions to alleviate congestion and pollution. Project P.U.M.A. addresses those concerns. It combines several technologies demonstrated by GM and Segway, including electric drive and batteries; dynamic stabilization (two-wheel balancing); all-electronic acceleration, steering and braking; vehicle-to-vehicle communications; and autonomous driving and parking. Those technologies integrate in Project P.U.M.A. to increase mobility freedom, while also enabling energy efficiency, zero emissions, enhanced safety, seamless connectivity and reduced congestion in cities.

Project P.U.M.A. vehicles will also allow designers to create new fashion trends for cars, and to focus on the passion and emotion that people express through their vehicles while creating solutions that anticipate the future needs of urban customers.

The Project P.U.M.A. prototype vehicle integrates a lithium-ion battery, digital smart energy management, two-wheel balancing, dual electric wheel motors, and a dockable user interface that allows off-board connectivity. The result is an advanced and functional concept that demonstrates the capabilities of technology that exists today.

Built to carry two or more passengers, it can travel at speeds up to 35 miles per hour (56 kph), with a range up to 35 miles (56 km) between recharges.

Since the introduction of the Segway Personal Transporter (PT), Segway has established itself as the leader in the small electric vehicle space. Its approach to congestion and environmental challenges is balanced with a strong understanding of the functional needs of its customers, enabling them to do more with less. Segway has delivered more than 60,000 lithium-ion batteries to the market.

GM has been a leader in "connected vehicle" technologies since it introduced OnStar in 1996. Today, this on-board communications package connects six million subscribers in North America to OnStar safety and security services. GM has also pioneered vehicle-to-vehicle (V2V) communications systems and transponder technology. These and additional connected vehicle technologies could ultimately enable vehicles that don't crash and drive themselves.

GM HydroGen4 Concept, 2008




With GM HydroGen4 the goal of achieving sustainable mobility with zero emissions came a step closer when GM announced the European part of its biggest ever test programme for fuel cell vehicles.

Nine companies will be the first to operate GM's HydroGen4 zero-emission vehicles in the Berlin area as they go about their day-to-day business: ADAC, Allianz, Coca Cola, Hilton, Linde, Schindler, Axel Springer, Total and Veolia. This real-world road test will run under the umbrella of the Clean Energy Partnership (CEP), a German Federal Department for Transport, Building and Urban Development funded project focused on proving the day-to-day suitability of hydrogen as a fuel for road transport.

GM HydroGen4 on the Road
As an integral part of GM's overall advanced technology strategy towards further electrification of the car, this fourth generation fuel cell vehicle is the culmination of more than 10 years development work with hydrogen and fuel cell technology. The HydroGen4 features improvements in everyday usability, such as performance and durability. Globally, GM deploys more than 100 vehicles of this type in its Project Driveway testing programme in the U.S., Japan, Korea, China, and Germany. In the U.S., more than 100,000 people have applied as mainstream drivers for the market test. To date, 3,400 people have driven the vehicles and 30 families have used the vehicle on a daily basis over a period of around three months. In total, the vehicles were driven almost 435,000 miles. Feedback from these demonstration activities not only gives GM engineers essential validation data, but also provides a valuable insight into the likely ownership and driving experience of future customers.

The vehicles are equipped with a wireless data transfer system that assists engineers by uploading vehicle performance data to a company server. Maintenance of the vehicles deployed in Berlin will be done at a regular Opel dealer equipped with the personnel and tools necessary for servicing fuel cell vehicles.

HydroGen4's fuel cell stack uses 440 single cells which combine hydrogen and oxygen from the air to produce electricity, with water vapour as the only by-product, and therefore zero emissions. The fuel cell stack provides the electric energy for the 73kW-synchronous electric motor, delivering acceleration of 0-62mph in around 12 seconds and a top speed of 100mph.

The electric motor's instant torque characteristics also give the vehicle an excellent pick-up from low speed. The GM HydroGen4 is fitted with a 1.8 kWh buffer battery to store energy from the vehicle's regenerative braking system and cover peak electrical loads. The three carbon-fibre composite tanks hold 4.2 kg of hydrogen at a pressure of 700 bars, sufficient for an operating range of up to 320 kilometres.

GM HydroGen4 can start and run in sub-zero temperatures, a considerable advance over the previous generation technology and an important benefit for everyday usability. It is designed to be as safe as conventional vehicles and includes unique hydrogen safety features in each of its major systems.
