NHTSA urges owners of recalled Takata airbag vehicles to take immediate action

The National Highway Traffic Safety Administration and the Department of Transportation are taking the unusual step of issuing a followup press release urging owners of certain recalled vehicles "to act immediately" to fix their cars and trucks. The problem in question concerns the repair campaigns for rupturing Takata airbag inflators issued in June and covers a long list of models from Toyota, Lexus, Honda, Acura, Mazda, BMW, Nissan, Infiniti, Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac.
While NHSTA doesn't specifically say why the recall is vital in the new release, Toyota's own explanation in its newly announced renotification campaign earlier today sheds some new light on the topic. According to the Japanese automaker, in testing, Takata found a possible link between the rupturing airbag inflators and high humidity. NHTSA is advocating that all owners pursue repairs immediately if they haven't already done so already. This is especially crucial for those drivers especially in Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii because of the humid conditions there.
We don't need to tell you how dangerous an inadvertent airbag deployment could be - even in a stationary vehicle - but adding to the Takata issue is fears that the deployment could lead to shrapnel being sprayed into the cabin.

Recharge Wrap-up: Nissan Leaf top environmental performer, 50,000th Renault Zoe

Renault has produced its 50,000th Zoe electric car. A Frenchwoman named Sylvie took ownership of the milestone vehicle at the Flins plant where it rolled of the line. She says her children helped convince her to buy the all-electric vehicle, which Sylvie intends to use as a daily driver. The Renault Zoe is Europe's best selling EV since its launch in 2013. Renault reports a 98-percent satisfaction rate with the Zoe. Read more in the press release from Renault. Toyota will use a biosynthetic rubber called biohydrin in its engine and drive system hoses beginning in May 2016. Jointly developed by Toyota, biohydrin is a plant-based rubber with a 20-percent reduction in material lifecycle carbon emissions compared to petroleum-based rubber. Toyota plans to use the compound in even more components in the future, including brake and fuel line hoses. Read more from Toyota. So far in 2016, only 27.5 percent of hybrids and EVs are traded in for another electrified vehicle, according to Edmunds. That's down from 38.5 percent in 2015. 33.8 percent of electrified vehicles are traded in for SUVs. Despite the trend of EV and hybrid owners switching back to traditionally powered vehicles, average fuel economy isn't suffering. "This is an economics trend, since today's low cost of gas no longer makes it worth paying the price premium of hybrids and EVs," says Edmunds Director of Industry Analysis Jessica Caldwell. "And there are so many fuel-efficient vehicles on the market today that environmental concerns weigh less than they might have in years past. When you're buying a vehicle that can get over 30 mpg, you can still say you're doing your part to help the environment." Read more from Edmunds. Environmentally, electrified vehicles outperform their conventional combustion counterparts throughout their lifecycle. A study from the Automotive Science Group (ASG) finds that while production of advanced powertrains comes with a greater financial burden, most vehicles make up for it through efficiencies during their use phase. The ASG lists the 2016 Nissan Leaf as its best performer, with 47 percent fewer greenhouse gas emissions than the best-performing conventionally powered car, the Honda Fit. Rounding out the ASG's top five environmental performers are the Ford Focus Electric, Chevrolet Volt, Toyota Prius Two Eco, and Hyundai Sonata Plug-In Hybrid.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.
