start-stop system

Some of the most exciting hybrid technology isn't coming from Japan or the U.S. these days, but France. The PSA group, comprising Peugeot and Citroen, has already attracted plenty of attention for its hybrid-air technology. Now, it's looking for ways of improving the batteries in "micro hybrid"...

Visit any European city, and you'll be struck by an unfamiliar sound: That of engines, previously silent, re-starting on every green light. A large number of cars in Europe now feature stop-start technology as standard, and while EPA mileage figures aren't favorable to its effects, they're starting...

Chevrolet has released details of its latest 2014 Malibu, set to go on sale this fall. Among the changes, the biggest news is that all Malibu models will get stop-start technology on the standard model--shutting down the engine when stopped to conserve fuel. Fitted to a new 2.5-liter gasoline...

It's taken a while for carmakers to begin fitting stop/start systems to U.S. vehicles, such systems' benefits not really advertised to consumers in a car's EPA numbers. In the real world though, many manufacturers say the systems can save you significant amounts of fuel--particularly if you...

Today at the Los Angeles Auto Show, Kia took the wraps off its new compact car, the 2014 Kia Forte. As our live images from the show floor demonstrate, the 2014 Forte is a sleeker, more aerodynamic four-door sedan than the car it replaces--now much closer in shape to its Hyundai Elantra sibling...

Mazda has supplemented i-Stop with a capacitor-based regenerative-braking system, called i-ELOOP, that should provide some of the benefits of a mild-hybrid system without added bulk.

According to a recent study by Pike Research, the fuel-saving technology which will be most prevalent in green cars by 2015 isn’t the current offering of hybrid drivetrains, fully electric cars or even hyper-efficient, four-cylinder engines, but stop-start technology. But will it really catch...

Almost every day we hear of a shiny new car that gets a certain number of miles to the gallon, a number often greater than its predecessor. It sometimes seems like witchcraft - until significant steps towards high-tech materials are taken, rarely do cars lose weight from one model to the next (with...

It's widely accepted in the auto industry that all manufacturers game the test cycles used to establish emissions and gas-mileage ratings. Ask auto engineers about the topic, and they tend to get a faraway look and go silent. But the test cycles established in 1978 and used ever since are far from...

Over several years, Mazda's i-Stop engine start-stop feature has helped owners in other markets to save on their fuel budget—and it's helped commuters in some of the most traffic-clogged areas be a little greener.

The rumors started last week, and they were largely true: Buick plans to offer a model of its Regal compact sports sedan with the eAssist mild-hybrid system. What we didn't have were the projected EPA mileage ratings (based on GM's internal tests). The company expects the 2012 Buick Regal with...

Buick plans to add its eAssist mild-hybrid system to the 2012 Regal sedan as an option, making the Regal its second model to offer the mileage-increasing system. According to trade publication Ward's Auto, Buick will introduce the option at the Chicago Auto Show next week. Last November, General...

Start-stop systems, which shut off car engines when the vehicle comes to a stop, have been offered in Europe for several years. But until now, no automaker other than Porsche has offered them on U.S.-market cars. That's about to change. Ford said yesterday it will offer the systems on some of its...

Sometimes even well-informed industry analysts get it wrong. Or miss the forest for the trees. A recent posting by Pike Research, entlted "Europe Leads, U.S. Lags In Start-Stop Hybrids," correctly notes that adoption of start-stop systems is well advanced in Europe, but lags behind in the U.S. But...

No, it's not pronounced "hell" ... although that word was heard from many Modena fans when news first broke that Ferrari was planning a hybrid-electric drivetrain in some models. The first fruits of Ferrari's wide-ranging quest to improve the fuel efficiency of its models was unveiled at the Paris...

Nissan has showed us the future of the automobile with its advanced Leaf all-electric vehicle but that doesn’t mean it’s game over for the internal combustion engine. Gasoline and diesel powered cars can live on, well into the future in fact, thanks to new fuel-saving technologies that Nissan...

We've always been fond of the 2010 Mazda Mazda5 small minivan, which gets rave reviews for its sporty character and good roadholding. Because it's smaller than more conventional full-size minivans like the Dodge Caravan, Honda Odyssey, and Toyota Sienna, it has always sold in smaller numbers. But...

We previewed the upcoming 2011 Mazda2 subcompact a couple of months ago, but now we have more details, along with photos of its updated styling. The five-door hatchback will be officially unveiled in early December, at the Los Angeles Auto Show. The 2011 Mazda Mazda2 will go on sale in the U.S. and...
