“If we can really understand the problem, the answer will come out of it, because the answer is not separate from the problem.” – Jiddu Krishnamurti

“The dogmas of the quiet past are inadequate to the stormy present. The occasion is piled high with difficulty, and we must rise with the occasion. As our case is new, so we must think anew and act anew.” – Abraham Lincoln.

Grand Challenges can be defined as fundamental problems in need of solutions. An Energy Grand Challenge is indeed what its name implies – a competition to be challenged and won in regard to energy use, sustainability, cost, and efficiency.

Multiple teams enter as candidates to reach the goal, whether it is a certain level of fuel efficiency, carbon dioxide removal, or future energy solutions. The winner receives a prize, usually in the form of a generously large sum of money. But the Challenge’s impact, however, is not only on the team that wins the grand prize, but the technology that springs from the research, which can expand its positive influence to affect the world.

With fuel prices rising with no end in sight, both consumers and automobile companies have become more and more concerned with fuel-consumption. While drivers attempt to cut down their gasoline usage, automobile companies are researching and producing more fuel-efficient cars, some to come out as early as next year.

Solutions range from hybrids, fuel-efficient engines, pure electric, plug-ins, solar panels, and hydrogen-powered vehicles. Even with all these seemingly promising solutions, will we have fuel efficient cars available for consumers at an affordable price by 2013?

To help us imagine just what the market has in store for us over the next 5 years here’s a timeline based on the self-reported release dates of various major auto manufacturers (visual first, followed by extensive text):



2009 Vehicles:

- Released by General Motors late 2008, early 2009, is the Saturn Vue 2-Mode hybrid. Touted as the world’s most fuel-efficient V-6 SUV, the Vue 2-Mode hybrid has up to a 50% fuel economy increase for urban driving and an overall 30% increase through the use technology such as low-speed, electric only propulsion and regenerative breaking. It will be classified as a Partial Zero Emissions Vehicle.

- In February, Shelby SuperCars will be releasing the Ultimate Aero EV, which will be the world’s fastest electric car. SSC is known for the EV’s predecessor, the Ultimate Aero, the world’s fastest gas-powered car. The Ultimate Aero EV will have twin 500 hp electric motors powered by a battery. Other details regarding its production have not been disclosed.

- Sometime in the Spring, the next generation of Toyota Prius will be released, equipped with solar panels that will provide a portion of the energy to run the air-conditioning unit. Toyota is planning on bringing 450,000 of these solar-power capable vehicles to the market.

- Audi will be bringing out their 2009 A2, a compact, fuel-efficient car that manages to feature more cabin space than Minis. The A2 will have 1.2 to 1.8 liter engines, as well as diesels and will have a lowered amount of CO2 emissions, due to the European CAFE regulations.
