One of the great challenges for automakers today is determining which technology or group of technologies will be the most effective in increasing fuel-efficiency and lowering greenhouse emissions – while still meeting the performance, quality and price car-buyers expect. The array of choices available and under development is significant, ranging from turbo charging, direct injection, six speed transmissions, electric power assist steering, weight reductions, electrification, bio fuels and hydrogen fuel cells.

We know there is a viable future for some of the most advanced technologies, but we also recognize not all of them are market-ready or affordable for consumers. Even advanced technologies take time to gain widespread acceptance. For instance, despite mainstream acceptance of hybrid technology, hybrids remain less than 3% of the market.

Like it or not, at least for the near future most of us are stuck with internal combustion engine powered cars. While a lot of hype is behind future cars and technology, from electric to hydrogen to everything in between, a lot of improvements can yet be made on the ICE engine.

To that end, the Department of Energy has awarded GM with $2.7 million to develop a working prototype of a Shape Memory Alloy engine. In theory, this engine could recycle the waste heat and turn it into electrical energy, perhaps one day even replacing alternators and improving fuel efficiency.

Many of you have heard of Ricardo, a company that has a rich history in Motorsports. However, most of you probably haven’t heard of Recaptured Energy Technologies (RET), until now. The company has just announced a partnership with Ricardo to develop and produce “Green Solutions” to the fuel and emissions problems that plague fleet, commercial and transit vehicle operators.

RET’s basic technology is this: they have a retrofitable hydraulic propulsion system for large vehicles that stores energy in hydraulic cylinders with compressed gas. The vehicle, such as a city bus, then uses that stored energy to give it a boost when starting up. The technology is known as RPS, or Retrofitable Propulsion System, and reduces fuel use by 25 percent and emissions by 25 percent. But before you finish mumbling about how improved fuel economy doesn’t eliminate our dependence on fossil-fuel based energy, this system can improve the fuel and emissions of vehicles using all forms of fuel including ethanol, biodiesel, compressed natural gas, propane and more.

“We like to say that the vehicle is indifferent and fuel agnostic,” said Sam Jones, President of Recaptured Energy Technologies.

Since its humble beginnings in the 19th century, the sparkplug has been a mainstay of the combustion engine.

Some engineers at Ford, in collaboration with Liverpool University researchers have decided to modernize spark plug technology. Since we’re in the 21st century, that replacement is going to be lasers.

Yes, I said lasers.

The first car my best friend ever drove was a early 80’s Honda Accord hatchback. It was little more than an oversized rollarskate with a tiny, 80 horsepower engine, but it beat the hell out of walking. The car itself was cramped and lacked all the amenities one would find standard on today’s cars, even cupholders. Today, the car serves as an immobile flower bed for a maple tree and wildflowers, but the memories will remain.

Flash forward to today, and a new study finds that since the early ’80’s the Honda Accord has packed on over 1,000 lbs, doubled its standard horsepower, and fuel economy has steadily dipped. The study seems to suggest that if vehicle weight, horsepower, and torque were held at their 1980’s levels, then fuel efficiency could have increased by at least 50%, rather than the 15% increase that actually occured. But is it really that simple?
