Over Half of All Cars to Feature Stop-Start by 2024

But consumer complaints remain a problem.

by on Apr.13, 2015

The new Malibu is one of many new vehicles adding Stop-Start and other advanced fuel saving technology.

When the new 2016 Chevrolet Malibu rolls into showrooms later this year it will offer a variety of powertrain options including a base 1.5-liter turbo package that will feature standard Stop-Start, making it the latest in a growing list of models equipped with the fuel-saving technology.

Within the next decade, forecasts Navigant Research, Stop-Start will be standard equipment on the majority of new cars, trucks and crossovers sold worldwide, according to a new study by Navigant Research. That’s more than double today’s numbers.

“The basic Stop-Start system is gradually evolving into one piece of a multifaceted approach to improving fuel economy in light duty vehicles,” according to Navigant’s senior research analyst David Alexander.


New Stop-Start Engines Boosting Mileage up to 7%, Reports AAA

Technology becoming more widely available, often as standard feature.

by on Jul.24, 2014

A full 97% of Chevy Malibu buyers are opting for the version with Stop-Start standard.

With increasingly stringent mileage standards coming down the pike over the next decade, automakers are frantically racing to find ways to boost the fuel economy of their vehicles. Some new features would yield benefits that are barely measurable, others could add significantly to a vehicle’s price tag. But new Stop-Start engines are delivering significant mileage benefits, often without additional cost to consumers.

A new study suggests that Stop-Start technology – which shuts an engine off, rather than idling – can reduce fuel consumption by anywhere from 5% to 7%. And it achieves a similar reduction in the production of global-warming CO2 emissions, according to research by the AAA.

“Up to seven percent improved fuel economy can mean a $179 annual fuel savings* for consumers,” says Greg Brannon, Director of AAA’s Automotive Engineering and Industry Relations team. “The technology requires only minor adjustment for motorists – automatic stop-start technology is simply applied to standard combustion engines.”


Chrysler the Latest Maker to Add Stop/Start Technology

Fuel-saving system to debut on new Chrysler 200, Jeep Cherokee.

by on Jun.24, 2014

The 2015 Chrysler 200 will be the first vehicle to get stop-start technology with the Jeep Cherokee coming along later this year.

Chrysler will offer the new stop-start technology on two of its newest models for 2015, with more products likely to get the fuel-saving system over the next few years.

Stop-start will become standard on the 2.4-liter version of the all-new 2015 Chrysler 200 sedan, as well as on the Jeep Cherokee equipped with the maker’s 3.2-liter Pentastar V-6.

The Word is "Free"!

The technology briefly shuts the engine off when the vehicle comes to a halt at a stoplight or on, say, a fast food line, automatically firing back up when the driver’s foot lifts off the brake. Estimates of the benefits vary, though Chrysler predicts stop-start should improve fuel economy by about 3% on the Chrysler 200 and Jeep Cherokee, while reducing emissions by about 3%, as well.

How Automakers Will Get to 54.5 MPG

Battery cars are only part of the answer.

by on Aug.29, 2012

At 47 mpg, the new Ford C-Max will be one of the market's most efficient vehicles. But it still has a long way to go to meet the new 54.5 mpg CAFE standard formalized this week.

When Ford launches its new C-Max hybrid microvan later this year it will deliver a solid 47 mpg in the EPA’s combined city/highway test, making it one of the most fuel-efficient vehicles on the road. Yet that’s still about 15% short of the target the White House has set for the auto industry with the new mileage standards that will be phased in between now and 2025.

Most major automakers signed onto the compromise regulations announced last year and officially released on Tuesday. But most echo John Krafcik, the CEO of Hyundai Motor America, who admits “We don’t yet know how we’ll get there.”

Electrification will almost certainly play a role, in some form or another.  But don’t expect to see America switch to battery cars, most industry analysts contend.  The technology will likely remain too limited and too expensive over the next dozen years – and the infrastructure just won’t be there, contends Jim Hall, of 2953 Analytics.


Stop-Start to Be in 8 Million Vehicles by 2017

New study predicts major savings in fuel bills.

by on Aug.13, 2012

Ford will offer stop-start as a $295 option on the 2013 Fusion.

You come to a stoplight and press the brake pedal and the car suddenly seems surprisingly quiet.  As the light turns green and you move your foot back to the throttle you hear a brief rumble from under the hood and pull forward as if nothing had happened.  That’s because the vehicle’s stop-start system worked as it was supposed to, briefly powering down your engine instead of idling in order to save gas.

The technology first appeared on the original Honda Insight and Toyota Prius hybrids, a dozen years ago, and is now a standard feature on the growing number of gas-electric vehicles offered in the U.S. market. But a number of manufacturers are starting to add the fuel-saving technology to their more conventional car, truck and crossover lines.

In fact, a new study by the Lux Research estimates stop-start will be offered on as many as 8 million vehicles sold in the U.S. by 2017 – and some forecasters believe it will be even more common in Europe and Japan, where fuel costs justify the technology’s modest price premium.


Jaguar Downsizes Engine Line-Up

Adds first U.S. 4-cylinder, and a supercharged V-6 for big XJ.

by on Jun.29, 2012

The 2013 Jaguar XJ will swap its 5.0-liter V-8 for a supercharged V-6.

Bigger is better, or so the traditional logic has gone when it comes to the luxury market – and especially powertrain options.  But facing tough new emissions and mileage mandates – and shifting consumer demand – manufacturers like Jaguar are downsizing both their vehicle lines and their engine offerings.

The British marque has revealed plans to offer its first-ever inline-four in the U.S. market for 2013.  And the coming model-year will also see Jaguar replace the 5.0-liter V-8 in its XJ flagship with a new supercharged 3.0-liter V-6.

We Brake for News!

Among other powertrain news for 2013, the British luxury marque will introduce a new 8-speed automatic and will add Stop/Start technology.  The latter feature – already being offered by such high-line brands as Porsche and BMW – automatically shuts off the engine when idling, say, at a stop light. The engine instantly fires back up when the driver’s foot lifts off the brake.


Kick-Starting Start-Stop

Feds the obstacle with mileage boosting technology.

by on Oct.07, 2011

Porsche was one of the first to offer American motorists Start-Stop technology in a non-hybrid vehicle with the launch of the Panamera.

Are federal regulators inadvertently blocking widespread adoption of new technology that could significantly improve the fuel economy of most new vehicles at a relatively modest cost?

Auto industry officials complain that the Environmental Protection Agency is discouraging the industry from using Start-Stop, a technology that can briefly shut down a vehicle’s engine instead of wasting gas by idling.  The feature, widely used in Europe and Japan, can boost the fuel economy of a typical passenger vehicle by as much as 5%.

Your Trusted Source!

The problem is that the government’s often-criticized fuel economy test cycle does not account for the advantages of Start-Stop, making it hard to justify the added cost – about $300 to $500 a vehicle – if a maker cannot show consumers that it is boosting their mileage and saving them money in the long run.

The 2012 Kia Rio will introduce Start-Stop technology into the mainstream American market.

“Fuel economy is now the number one concern for American car buyers,” notes Derrick Kuzak, Ford Motor Co.’s global product chief.  And that is prodding the maker – and its competitors – to adopt all sorts of new technologies that can increase a vehicle’s fuel efficiency.  That includes new 7-, 8- and even 9-speed gearboxes, low rolling-resistance tires and downsized, turbocharged engines like Ford’s popular EcoBoost system.

But in a hotly competitive marketplace, warns Kuzak, a maker needs to get a return for its investment.  And that means the bragging rights of showing potential buyers an improvement in fuel economy.

Yet even though automotive experts universally agree that Start-Stop routinely yields a 3% to 5% improvement in mileage – and sometimes more – manufacturers have no way to show that on the Munroney window stickers customers routinely check when they go car shopping.

So, for the moment at least, Start-Stop systems are available only on about 2% of the cars, trucks and crossovers sold in the U.S. — primarily on gas-electric vehicles, such as the Ford Fusion or Toyota Prius, where the necessary componentry is already built into the vehicle.

Experts say that today’s engines can save fuel shutting down for as little as 15 to 30 seconds rather than idling at a light or drive-up window.  Start-Stop makes it simpler than having to switch a key on and off.

The basic operation is simple: when a vehicle comes to a stop and the driver steps on the brake the engine shuts down.  Lift off the brake and the engine automatically fires up again.

Federal regulators have promised to examine the technology and may either modify their test procedure or come up with an algorithm that would boost the numbers for a vehicle using Start-Stop.  On a typical car, the savings might add up to $100 or more annually, justifying the added expense, industry observers contend.  And this way, buyers would directly understand the benefits.

Some makers have decided not to wait for the feds to act.  Kia will become the first mass-market manufacturer to offer Start-Stop on a conventional, non-hybrid model.  It will become available on the 2012 Kia Rio as part of a $400 “Eco” option.  The base Rio will go for $14,350.

Ford, meanwhile, says it will begin offering the technology on some of its new models next year.

It’s already available on some high-line products, notably from BMW and Porsche – the latter first introducing it on the Panamera, its 4-door sports car.  The maker claims the technology has proven particularly effective on its high-performance products, bumping up the fuel efficiency of the all-new Porsche 911 by as much as 15% in the European fuel economy test process.

It can take a bit of getting used to Start-Stop, feeling the engine suddenly stop at a light and then restarting, almost like magic, when it’s time to move forward.  But on many models the technology operates so smoothly a motorist might not even know, especially if the radio is on, hiding the sudden silence from under the hood.

Some see Start-Stop as a sort of “bridge” between conventional gasoline or diesel-powered vehicles and all-electric products.  Others contend that with the use of more limited high-tech systems – such as Start-Stop – the internal combustion engine will become so much more efficient it will become hard to justify pure battery-electric powertrains.

Research by IHS Automotive suggests Start-Stop will see a tenfold increase in use in the U.S. by 2017, to around 20%.  Some experts, including Ford powertrain planners, believe the technology could actually become almost ubiquitous in another decade – especially if makers are allowed the bragging rights for the high-mileage systems.
