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.

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.

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?

Nissan has announced plans to sell compact hybrid vehicles based on its own technology in Japan, starting from 2011.

The Japanese outfit intends to make a low-cost, compact powertrain featuring an integrated electric motor providing supplemental power to the main gasoline engine. Energy will be provided by high-performance lithium-ion batteries.

According to Nissan the hybrids should be more than twice as fuel efficient as the equivalent gas-powered offerings.

The issue of rainforest destruction (which many experts say is NOT a primary result of increased biofuels production) segues in to the debate of “good biofuels versus bad biofuels”. A bad biofuel may be one that uses food crops, excessive land and too much water. A better biofuel uses biomass, or waste, little water and little to no land.

Ever wish you could buy a car that would run on just about anything?  An engine that gave you something approaching the efficiency of diesel, and the convenience of gas?  Last week, the forward-thinkers at Lotus announced just that.

It’s called the Lotus Omnivore, and we’ve got all the details on this little, all-aluminum marvel.

Editor’s Note: Our friends at Popular Mechanics have written an in-depth piece about an essential piece of fuel-saving technology: the turbocharger. Read the rest of this story at PM.

In the 1980s, it was difficult to escape the turbocharger. The twin energy crises of the 1970s forced automakers to produce cars that delivered better fuel economy. And that meant downsizing engines. By the 1980s, turbo technology was evolving and automakers installed them to boost the power of these smaller engines. But turbos promised more than just power—they promised fuel economy benefits too.

Several weeks ago, I filled you in on Bentley’s upcoming ethanol supercar, promised to be the fastest, most powerful Bentley ever offered.

In the days since, Bentley has kept the world’s journalists hungry for more details, releasing only this “Project Victoria” teaser video, a March reveal date, and precious little else… but has one of Volkswagen’s lesser-known suppliers inadvertently given away Project Victoria’s horsepower secrets?

You bet! Read it here first, after the jump.

The name of Ford’s new V6 engine seems to imply that power is somehow boosted by some naturally occurring and environmentally sustainable green technology, like tree leaves, or a river.  Cars are a long way from being environmentally friendly, regardless of the technology that’s been developed and put into hybrid and electric cars.  Electrical outlets don’t grow own trees, and in fact, much of the electricity we use is powered by coal, not exactly a clean or sustainable technology.

UPS will field two hydraulic hybrids in Minneapolis, MN, in early 2009 and an additional five hydraulic hybrid trucks will be deployed later in 2009 and early 2010. Although this sounds like a tiny fleet, keep in mind that this is the largest scale commercial test of hydraulic hybrids ever conducted.

The UPS hybrid hydraulic truck is a standard-looking 24,000 pound package car, with an EPA-patented diesel series hydraulic hybrid drive attached to the rear axle.

A senior economist at the Argonne National Laboratory has come to an interesting conclusion: vehicles that rely on internal combustion engines are superior to electric vehicles in terms of what consumers would buy and what would save significant fuel.

Even though Tesla is delivering their cars to consumers several years before the Volt hits the show rooms, from the perspective of Dan Santini, you and I are more likely to get our hands on Volt-style vehicles first.

Some of the main obstacles that stand between us and pure EVs were identified at the 1st International Conference on Advanced Lithium Batteries for Automotive Applications, sponsored by the Argonne National Laboratory (where Dan Santini works).

Although Ford’s first generation Ecoboost engines start hitting the market next year — promising a 20% gain in fuel economy over traditional engines — Ford is already tweaking their new Bobcat technology to squeeze out even more fuel efficiency from the direct ethanol injection system.

The technology works by merging a turbocharger with a high compression ratio in the same engine. Combining these two features normally results in an incompatible and disastrous mix which causes premature detonation of the fuel/air mixture — referred to as engine knock.

The Northwest Biofuels Association has produced a joint letter about biodiesel warranty protocol intended to set the record straight for auto dealers (and everyone else that’s confused about the issue).

Recently, I wrote about how biodiesel’s new ASTM standards could go a long way in improving warranty coverage for biodiesel use in your new car. NW Biofuel’s letter goes into a little more detail, and gives you a reference you can give to your dealership or keep in the glove box. Here’s what you should know:

• Whether or not a biodiesel blend is “recommended” by your automaker is separate from the question of whether the use of biodiesel affects engine warranty coverage. Make sure you know exactly what your automaker specifies.
• Because vehicle warranties only cover parts and workmanship, fuel is not covered under any vehicle warranty.

  Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they’ve created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a conventional internal combustion engine of the same horsepower. Oh yeah, did I mention that it doubles the fuel economy too.

  What that means is a car like the 2007 Toyota Yaris, which is rated at 40 mpg on the highway, would get 80 mpg with a Revetec engine.

  This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims.

Every one of those trucks gets an average of 7 mpg, carries upwards of 200-300 gallons of diesel, and spews out potentially harmful emissions.

  Like it or not, we depend on them to bring us our food, fuel, and products for everyday living. It’s a connection that most of us often forget about, only remembering it long enough to curse them as they slow us down on the highway.

  It’s also an industry that has recently been hit hard by soaring fuel prices, and now, with the average price of diesel in the US at $4.70/gallon and climbing, it’s sure to get worse.

  Needless to say, there’s a rising cacophony of voices within the trucking industry clamoring for relief. Most of this noise currently comes in the form of wanting a break in fuel prices, but really that’s just a temporary fix. Any solution with sticking power would have to offer both economic and environmental benefit — you know, win-win.
