Lexus tops JD Power Vehicle Dependability Study again, Buick bests Toyota

It shouldn't surprise anyone, but Lexus has once again taken the top spot in JD Power's Vehicle Dependability Study. That'd be the Japanese luxury brand's fourth straight year at the top of table. The big news, though, is the rise of Buick. General Motor's near-premium brand beat out Toyota to take second place, with 110 problems per 100 vehicles compared to Toyota's 111 problems. Lexus owners only reported 89 problems per 100 vehicles. Besides Buick's three-position jump, Scion enjoyed a major improvement, jumping 13 positions from 2014. Ram and Mitsubishi made big gains, as well, moving up 11 and 10 positions, respectively. In terms of individual segments, GM and Toyota both excelled, taking home seven segment awards each. The study wasn't good news for all involved, though. A number of popular automakers finished below the industry average of 147 problems per 100 vehicles, including Subaru, (157PP100), Volkswagen (165PP100), Ford/Hyundai (188PP100 each) and Mini (193PP100). The biggest losers (by a tremendous margin, we might add) were Land Rover and Fiat, recording 258 and 273 problems per 100 vehicles. The next closest brand was Jeep, with 197PP100. While the Vehicle Dependability Study uses the same measurement system as the Initial Quality Survey, the two metrics analyze very different things. The VDS looks at problems experienced by original owners of model year 2012 vehicles over the past 12 months, while the oft-quoted IQS focuses on problems in the first 90 days of new-vehicle ownership. Like the IQS, though, the VDS has a rather broad definition of what a problem is. Because of that, a low score from JD Power is no guarantee of extreme unreliability, so much as just poor design. In this most recent study, the two most reported problems focused on Bluetooth connectivity and the voice-command systems. The former leaves plenty of room for user error due to poor design (particularly true of the Bluetooth systems on the low-scoring Fords, Volkswagens and Subarus), while the second is something JD Power has already confirmed as being universally terrible. That makes means that while these studies are important, they shouldn't be taken as gospel when it comes to automotive reliability.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

Defying Trump, major automakers finalize California emissions deal

WASHINGTON — The California Air Resources Board (CARB) and major automakers on Monday confirmed they had finalized binding agreements to cut vehicle emissions in the state, defying the Trump administration's push for weaker curbs on tailpipe pollution. The agreements with carmakers Ford Motor Co, Volkswagen AG, Honda Motor Co and BMW AG were first announced in July 2019 as voluntary measures prompting anger from U.S. President Donald Trump. A month later, the Justice Department opened an antitrust probe into the agreements. The government ended the investigation without action. The Trump administration in March finalized a rollback of U.S. vehicle emissions standards to require 1.5% annual increases in efficiency through 2026. That is far weaker than the 5% annual increases in the discarded rules adopted under President Barack Obama. The 50-page California agreements, which extend through 2026, are less onerous than the standards finalized by the Obama administration but tougher than the Trump administration standards. The automakers have also agreed to electric vehicle commitments. Volvo Cars, owned by China's Geely Holdings, said in March it planned to join the automakers agreeing to the California requirements. It has also finalized its agreement. The settlement agreements say California and automakers agreed to resolve "potential legal disputes concerning the authority of CARB" and other states that have adopted California's standards. In May, a group of 23 U.S. states led by California and some major cities, challenged the Trump vehicle emissions rule. Other major automakers like General Motors Co, Fiat Chrysler Automobiles NV and Toyota Motor Corp did not join the California agreement. Those companies also sided with the Trump administration in a separate lawsuit over whether the federal government can strip California of the right to set zero emission vehicle requirements. Ford said the "final agreement will reduce emissions in our vehicles at a more stringent rate, support and incentivize the production of electrified products, and create regulatory certainty." BMW said "by setting these long-term, predictable, and achievable standards, we have the regulatory certainty that is necessary for long-term planning that will not only reduce greenhouse gas emissions but ultimately benefit consumers as well."
