Fuel Efficiency

  • heat2power thermal energy recovery system

    Despite decades of modern advancements, it’s common knowledge that internal combustion engines are far from efficient when it comes to transmitting the energy stored in the fuel they burn into real motion. In the recent past we’ve seen regenerative braking, engine stop-start and direct injection systems appear on new cars in an effort to boost efficiency but there’s still a lot that can be done. One avenue that’s been receiving a lot of interest recently is thermoelectric power generation, a process where electricity is generated from wasted exhaust gases. Some of the...

    U.S. raises fuel economy floor to 27.3mpg for 2011

    You might disagree with his methods, but you can't deny President Obama's determination to improve the U.S. car industry's situation and to remedy the nation's current energy policy. Part of both plans is a rise in the fuel economy requirements to 27.3mpg fleet-wide by 2011. It's actually a step...

    Department of Energy's $25 billion fuel-efficient vehicle fund still untapped

    Last November, the Department of Energy issued interim rules for the use of a already-approved $25 billion loan package earmarked for the construction of more fuel-efficient vehicles. But now, almost five months later, there has still been no disbursement of the funds. Over 75 applications for the...

    Ferrari confirms 599 hybrid prototype in testing

    Governments around the world are bowing to public pressure to reduce greenhouse gases, and more often than not the first sector they look at is the auto industry. The European Council has proposed a ruling that could see carmaker’s forced to limit their fleet average CO2 levels to 130g/km by...

    Volvo adds four more cars to efficient DRIVe lineup in Geneva

    Slashing the cost of ownership is a good strategy in today's car market, especially in Europe where emissions taxes are a large part of the yearly expense. Volvo's DRIVe line of cars, expanded with four more models today, is therefore not just smart in an environmental sense, but a business sense...

  • avl turbohybrid 1

    Turbocharged, fun-to-drive hatchbacks and sedans - not the first things that come to mind when we hear the word 'hybrid' but one company is working to change that. Hybrid technology has become hugely important in the industry and to many eco-conscious drivers as well, and though it offers some serious benefits to fuel economy, as anyone who has driven one knows, they are often boring behind the wheel. AVL thinks that's not a mandatory situation, and is developing a system to inject fun back into the fuel-efficiency equation. AVL thinks that between equally efficient vehicles, buyers will...

    VW joins ranks of carmakers investigating thermoelectric generators

    Finding ways to make cars more efficient isn't always about improving the engine, changing the fuel or adding a hybrid system to the mix. Sometimes it's about recapturing some of the energy already expended. Volkswagen's thermoelectric generator applies that idea to waste exhaust heat, and turns it...

    First Scuderi split-cycle engine prototype completed

    American engineering firm Scuderi has announced the completion of the first prototype of its new ultra-efficient engine design called the ‘split-cycle’. The design uses a revolutionary new system to provide engines that release significantly fewer emissions than current offerings and is...

    Ford Fusion Hybrid qualifies for maximum tax credit of $3,400

    Tax credits designed to give buyers incentives to buy more efficient cars are anything but new - the Toyota Prius has benefited from similar schemes for several years. Now Ford's Fusion Hybrid, as well as the Mercury Milan Hybrid, qualify for the maximum tax credit as well, giving buyers a $3,400...

    Next-gen Ford Focus could feature EcoBoost powerplant, 43mpg

    Although Lincoln's C Concept may have struck few chords with show-goers, its theoretical internals could live on in a future Ford Focus. The latest reports indicate Ford is considering a 1.6L 180hp (134kW) four-cylinder EcoBoost engine for its next Focus, capable of pushing highway fuel economy as...

  • BMW 1-series three-door hatch

    The 1-series has been a popular staple among premium small-car buyers in Europe for some time, but it has only hit the U.S. recently. The fun-to-drive and attractive compact has just gained a new sibling in the form of the 116d, powered by an efficient four-cylinder diesel. Unfortunately it's only available in Europe. Despite the absence from American shores, it's still a technological feat to appreciate. With its 53.4 US mpg rating in the European combined cycle, the 116d is as efficient as the current Toyota Prius and next-gen Honda Insight hybrids. And at 116hp (86kW) and 192lb-ft (260Nm)...

    More than a year ago, Volkswagen announced it was working on a project to bring its 1-Liter concept from 2002 to production reality.

    Small car fuel savings offset by higher insurance costs

    Savings at the pump may be a false economy for small cars, as higher insurance costs offset the financial benefits of higher fuel efficiency. For many popular models, the difference in insurance costs can exceed $500, wiping out the savings of a car that gets 35mpg on average over one that gets...

  • 2009 Mercedes Benz C350 CGI BlueEFFICIENCY

    Mercedes Benz has introduced a new version of its C-Class sedan under the guise of its BlueEFFICIENCY eco tag. The car is the C350 CGI BlueEFFICIENCY, and despite producing more power and torque than the standard C350 it uses on average 10% less fuel. This is because of the addition of Mercedes’ second-generation direct injection technology instead of the standard C350’s port injection. There are also several other fuel saving mods such as a more aerodynamic grille and low rolling resistance tires. Output from the new saloon’s engine is rated at 292hp (215kW) and 270lb-ft...
