Honda’s fix for prematurely dying Civic hybrid batteries hurting fuel economy, performance?

Filed under: Hybrid, Sedan, Technology, Honda

Until the past year or so, the Civic Hybrid had been by far the best selling gas-electric model introduced by Honda. However, the second-generation model introduced in 2006 has not been entirely problem-free. There have been several lawsuits against Honda claiming that the Civic doesn’t meet its advertised mileage claims. While those sort of claims are often dubious given their dependency on factors like driving style, climate and terrain, premature battery failures are not.

According to the Los Angeles Times, it appears that 2006-2008 Civic Hybrid models are suffering an abnormally high rate of battery failure at relatively low miles. The nickel-metal-hydride batteries are evidently prematurely losing their ability to hold a charge – particularly in hot weather areas like Arizona and when used in a lot of stop-and-go traffic. The Civic Hybrid has a dual compressor air-conditioning system with an engine driven primary compressor and a smaller electric compressor to keep the system going when the engine is shut during a stop. Using the air conditioning will cause the battery to go through more charge cycles, eventually wearing it down. Read on after the jump for more on why the battery might be failing and how Honda is attempting to address it.

Update: Honda spokesman Chuck Schifsky let us know that the software updated for the 2006-8 Civics is based on the changes that were introduced for the refreshed 2009 models. The 2009 models apparently also got an updated battery but obviously that change isn’t going into the older cars. The original 2006-8 models would spend a lot of time during hot weather use with the A/C on which apparently caused the charge cycling rate to increase wearing down the battery.

Update 2: Honda confirmed that the battery pack did change from 2008 to 2009 but its not clear exactly what was updated.

Jaguar recalling 2010-2011 XF and XK over potential fuel starvation

Filed under: Coupe, Sedan, Government/Legal, Recalls, Safety, Jaguar

Jaguar’s new 5.0-liter V8 has seen its fair share of praise since its introduction, but even the best petrol mill is worthless without fuel. The National Highway Traffic Safety Administration website indicates that 5,048 of the automaker’s 2010 and 2011 XF and XK models equipped with the 5.0-liter engine are being recalled for a faulty fuel pump relay.

The problem can reportedly occur if the in-tank electronic fuel pump isn’t properly activated when the fuel pump relay is energized at vehicle start-up. When this happens, the engine could receive inadequate amounts of fuel, resulting in the vehicle abruptly stalling with little or no warning, which would potentially result in an unscheduled (is there another kind?) accident.

Beginning August 30 of this year (or possibly earlier) owners of affected vehicles can simply take their faulty cat to the nearest Jaguar store for a free software update that should fix the issue. Hit the jump to read over the NHTSA press release.

Nissan recalls 46,000 2009-10 Cube models over fuel system integrity

Filed under: Budget, Recalls, Safety, Hatchback, Nissan

Last month, the Lexus HS250h was the subject of a serious recall involving fuel leakage resulting from rear-end collisions. Now, Nissan faces a similar predicament involving 2009 and 2010 model year Cube hatchbacks, and the National Highway Traffic Safety Administration has issued a full recall, covering 46,000 Cubes built between January 30, 2009 and July 30, 2010.

Much like the HS hybrid, NHSTA cites that the amount of fuel leakage following a rear-moving barrier crash “exceeds the allowable limits,” and that this could result in a fire. While a fuel leak is bad news, it’s important to note that this NHTSA test isn’t simply a case of a simple crash test and resultant fuel leak – the government agency’s methodology includes striking the vehicle from the rear with a deformable barrier at 50 mph with a 70 percent overlap. Post-impact, the vehicle is then spun on its longitudinal axis degree-by-degree for a total of 90 degrees, somewhere along which a fuel leak was detected. While any fuel spillage is a bad thing, we suspect you can put any images of the massively overblown Ford Pinto debacle out of your head right now.

In any case, the full recall is expected to start on or before August 30. To fix the problem, dealers will install a special protector to the gasoline recirculation tube where it meets with the filler neck connector. Naturally, the service will be performed free of charge at any authorized Nissan dealer. The full details are available in NHTSA’s press release after the jump.

BMW recalling 2010-2011 5 Series, 5GT models over fuel tank sensors

Filed under: Sedan, Wagon, Government/Legal, Recalls, Safety, Crossover, Hatchback, BMW

If the fuel gauge in your 2010 or 2011 BMW 5-Series sedan or 5-Series Gran Turismo tells you that you’ve got plenty of petrol, you may want to hit the gas station before going on that long trip anyway. The National Highway Traffic Safety Administration website reports that 6,080 5-Series sedan and GT models built between January 12 and July 1, 2010 are being recalled for a faulty fuel sensor. In certain cases, the sensor can wedge itself against the tank, which will lead to the fuel gauge reading that the vehicle has more fuel than it actually does. Drivers suddenly saddled with a fuel-free Bimmer while driving could wind up getting into an accident or being stranded by the side of the road, and that’s not good at all.

The NHTSA website currently shows that BMW still hasn’t provided an appropriate fix for the issue, but when the automaker does, owners will doubtlessly be able to head over to the nearest BMW dealer for a free repair. Head across the jump to read over the official NHTSA press release.

Report: Infiniti to double fuel mileage with next hybrid

Filed under: Hybrid, Sedan, Technology, Infiniti, Nissan

Up to this point, Nissan has relied on hybrid technology purchased and licensed from the undisputed leader in hybrid vehicles. That would be Toyota, naturally. But the two Japanese automakers will be moving in separate directions in short order as Nissan has developed its own hybrid powertrain technology, and unlike most other automakers, Nissan’s system will debut powering a rear-wheel-drive machine wearing the Infiniti badge.

And there’s apparently another way Nissan and Infiniti’s first in-house hybrid system will differ from Toyota’s full hybrid and Honda’s mild hybrid architecture. According to Reuters, Koichi Hayasaki, Nissan’s chief engineer of its rear-wheel-drive hybrid system maintains that “Typically, carmakers say the fuel economy improvement on their cars using a ’strong’ or ‘full’ hybrid system is roughly 30 percent, while for ‘mild’ hybrids, it’s 15 percent. We’re aiming for an improvement of 60 to 90 percent.”

Further, Nissan claims its hybrid system will use a single electric motor and twin clutches (instead of two electric motors as used by Toyota), a move that ought to help make the system simpler and lighter than its competitors. It will also use lithium ion batteries instead of cheaper but less energy dense nickel metal hydride cells. If Nissan can manage to hit all of its targets, we may be looking at a new hybrid standard bearer.

2011 Ford Explorer with EcoBoost 2.0-liter delivers 30% better fuel economy than V6

Filed under: Ford

Ford has got the gas mileage goods on its 2011 EcoBoost-powered Explorer, and it’s news you might like if you want one: you’ll get 30 percent better mileage with the inline-four than you could with the outgoing V6. Ford did, however, leave a key detail out of the press release touting this: it didn’t reveal the actual mileage number, “pending EPA certification.”

Nevertheless, with the 2010 Explorer’s 210-horsepower, 4.0-liter V6 EPA rated at 14 miles per gallon in the city and 20 out on the highway, you’re looking at a healthy increase all over with the four-pot turbo doing the work up front. Follow the jump for Ford’s press release that details all the reasons your wallet won’t be so sad if you end up buying a 2011 Explorer.

Report: Audi developing new diesel fuel cap to avoid misfills

Filed under: Audi, Diesel

Audi is following BMW by introducing a mechanism to prevent misfueling of diesel vehicles with gasoline. It’s generally not possible to put diesel into a gasoline-powered vehicle as the larger diesel nozzles won’t fit in the filler neck. However, the smaller gas nozzles will fit in the diesel neck. Audi’s system, similar to the one used by BMW, adds a flap in the neck to prevent fuel flow. The flap only opens if the nozzle presses on contact points just below the cap. The smaller gasoline nozzle won’t be be able to hit all of the contacts at once and the flap will prevent fuel from getting into the tank. Apparently, the improved refinement of modern diesel engines has led to an increase in misfueling in recent years, prompting both BMW and Audi to add the new feature. BMW has had this mechanism in all of its diesel vehicles since early 2009 and Audi’s system is set to appear next year.

Subaru Forester gets new engine for 2011, improved fuel economy

Filed under: Crossover, Subaru

The current Subaru Forester started life with a Motor Trend SUV of the Year award, followed by strong sales that helped Subaru succeed in a down auto market. The story gets a bit better for the 2011 model year with a new 2.5-liter boxer engine and a host of added features.

The new engine retains the same displacement as the outgoing mill and achieves the same 170-horsepower, but it’s now packing a chain driven double overhead cam versus the belt driven single overhead cam before. The result is maximum horsepower available at a lower RPM and an additional four pound-feet of torque (to 174 lb-ft). The new 2.5-liter helps the Forester post 21 miles-per-gallon in the city and 27 mpg on the highway whether you’re sporting the manual or automatic transmission. That’s up one mpg versus the outgoing model.

Other changes include a new model; the Subaru 2.5XT Touring, which slots above the Limited model. Among the standard features on the Touring model are HID headlamps, backup camera and dual-zone climate control. Subaru is also adding a 2.5XT Premium model (old model was 2.5X Premium), which includes a 10-way power driver’s seat, an upgraded stereo with six speakers, Bluetooth and a USB port for your iPod. Also available is a removable 4.3-inch TomTom Navigation System for directions on the cheap. Hit the jump to read over the Subaru presser if you’re interested in all the details.

BREAKING: Lexus recalls HS250h over risk of excessive fuel leakage

Filed under: Hybrid, Sedan, Recalls, Safety, Lexus, Luxury

Back in the 1970s, the Ford Pinto was the focus of many headlines due to a fuel tank issue which caused excessive amounts of gasoline to leak during a rear-end collision. Now, three decades later, Lexus is having a similar problem with its HS250h hybrid, and has filed a report with the National Highway Traffic Safety Administration to issue a voluntary recall of these vehicles. Up to 17,000 of the luxury hybrids are affected.

In the case of the HS, excessive fuel leakage occurred during rear-end collisions at speeds of 50 miles per hour. We don’t need to remind you about the dangers of excessive fuel spillage, but let’s just say that the end result can be very, very bad.

As of this writing, Lexus has not advised NHTSA about what steps will be taken to fix the defective HS models. Make the jump for the full details.

Report: Toyota and Daimler planning “extensive cooperation” on fuel cell development

Filed under: Mercedes-Benz, Toyota, Earnings/Financials

Daimler began developing fuel-cell vehicles way back in 1994. To date, the company has spent $1.23 billion on the propulsion technology. Toyota entered into the hydrogen realm even earlier by kicking off development back in 1992. With decades of combined experience, both companies have become front runners in fuel-cell technology. Toyota and Honda became the first automakers to put commercial hydrogen fuel-cell vehicles on the roads back in 2002.

As you are likely aware, Toyota has teamed up with Tesla for development of electric vehicles at NUMMI. Now, a new report suggests that the company may join forces with Daimler (which also holds stake in Tesla) to develop affordable hydrogen-powered vehicles.

According to the Financial Times Deutschland (as reported in Reuters), Toyota and Daimler plan “extensive cooperation in the field of fuel cells for electric cars.” The Financial Times also suggests that the collaborative work could take the form of a joint venture. The newspaper contacted both companies for official confirmation, but Toyota denied knowledge of any such deal and Daimler was not available for comment.

Last year, some of the major players in fuel cell technology agreed to work together to promote the adoption of the hydrogen-powered vehicle. Within that group, we saw names like Daimler, Toyota, General Motors, Ford, Honda, Nissan and Hyundai. With so many companies pledging to combine their might on fuel-cell vehicle development, we assumed that some sort of joint venture would emerge. Tim Urquhart, an analyst at IHS Global Insight suggests that a Toyota-Daimler joint venture could benefit both companies. As Urquhart said:

The high development costs associated with trying to bring fuel-cell powertrain technology to production means that it is a highly logical step for Daimler and Toyota to try and share the costs and their extensive knowledge in fuel-cell technology.

At this point, it may just be wishful thinking, but we’d love to see a joint venture between the two companies. It would surely help out the hydrogen vehicle programs of each respective company and a joint venture might even bring more jobs back to NUMMI.
