Two Democrat Senators, Carl Levin and Debbie Stabenow, along with 14 House members from Michigan disputed President Obama’s informally proposed 56 mpg target for 2025 in a direct letter that predicts a loss of many American jobs if it comes into effect.

"We are deeply concerned that the administration's `starting' proposal of a five percent annual increase for cars and light trucks -- to reach a goal of 56.2 miles per gallon in 2025 -- is overly aggressive and not reasonable feasible," the 16 Michigan representatives said in their message to the President.

Hybrids and electric vehicles are more environment-friendly than conventionally powered models. However, one question many eco-conscious consumers bring up is what happens to the batteries at the end of their life cycle in the vehicles.

GM and Nissan estimate that batteries in their Volt and LEAF models respectively will have approximately 70% of their “life” remaining after a decade on the road. So, far from being useless, they can be utilized as back-up power sources for home use.

In the Spanish city of Murcia, the local pollies have come up with a unique solution to their burgeoning congestion problem.

Residents have the opportunity to trade in their cars for a lifetime pass on the city’s newly introduced tram system. Severiano Arias, the director of Murcia Transvia Society, explains:

“The point is to take cars out of circulation for the environmental benefits this brings. So we are only accepting working cars not ones ready for scrap heap because that would not serve any purpose.”

The 2011 Seoul Motor Show that runs in South Korea from March 31 to April 10 plays host to the world premiere of the all-new Hyundai Blue2 concept study. The name ‘Blue2’, which is read ‘Blue square’, is a combination of Hyundai’s sub eco-brand ‘Blue Drive’ and the number `2’ from H2, the symbol for hydrogen gas.

Codenamed HND-6, the prototype is Hyundai’s first sedan-style Fuel Cell Electric Vehicle (FCEV). The four-door saloon is powered by a fuel cell electric system that delivers a stack power of 90kW or 121HP and fuel economy of 34.9km/ℓ (of hydrogen, of course), which is equal to 82mpg US and 2.9lt/100km. The concept is also equipped with low-resistance tires and alloy wheels which are designed to improve aerodynamic performance.

Remember a few years ago when every wannabe gangsta was buying those awful “spinner” alloys for their beat up old Chevys and Oldsmobiles? Well, French artist and teacher Thierry Dumaine (who sounds like a character from a historical romance) has taken the concept of the spinner and applied it to an imaginary hydrid he calls the Ventile.

It’s all very simple. You know those bicycles that have pedal powered lights? Same principle, though in this case the fans are turned by the circular motion of the wheels and not by being affixed to the wheels themselves.

The fans power a generator that helps recharge the Ventile’s batteries. I don’t know how well this would work in the real world, mostly due to the Law of Conservation of Energy, but really who cares.

With gas prices going up and car owners downsizing from V6’s to four cylinders and from luxury models to economical subcompacts, the question for automakers becomes; how do we remain profitable? As the automotive big wigs descend on Geneva with their latest and greatest models, this issue is weighing heavily on many minds. So, how does one do it?

Well, there are a few answers to this conundrum, one of which is move your subcompact cars upmarket. MINI has done it, Toyota is sort of doing it with the iQ and no doubt many of the world’s other automakers would very much like a piece of that pie. The answer lies very much in the look of a car: its design and the ambiance it gives off.

The new Ferrari FF won't be the only model from Maranello to make its world premiere at the 2011 Geneva Salon, as Carscoop has learned that the Italian supercar maker will also introduce a greener version of the 458 Italia equipped with the company’s HELE (High Emotion, Low Emission) technology, which improves CO2 emissions and reduces fuel consumption.
