To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

10 of 18 midsize SUVs earn 'good' IIHS side impact safety rating

It's not terribly surprising that midsize SUVs earned better safety ratings than small SUVs in the latest side-impact tests performed by the Insurance Institute for Highway Safety (IIHS). Just how much better they scored, on the other hand, certainly raises an eyebrow. Ten out of 18 midsize SUVs earned the highest rating of 'good' in the stringent new test, altered for vehicles starting with the 2020 model year with a heavier barrier (4,200 pounds) that moves at a higher speed (37 miles per hour) and is fitted with a hard honeycomb frontal structure. By way of contrast, just one out of of 20 small SUVs earned a 'good' score.  SUVs that receiving 'good' scores were the Ford Explorer, Infiniti QX60, Lincoln Aviator, Mazda CX-9, Nissan Pathfinder, Subaru Ascent, Toyota Highlander, Volkswagen Atlas, Volkswagen Atlas Cross Sport and Volkswagen ID.4. For EV fans, it's worth noting the ID.4 was the only electric vehicle included in the test. The Buick Enclave and Chevrolet Traverse scraped away with 'acceptable' ratings while the Honda Passport, Honda Pilot, Hyundai Palisade, Jeep Wrangler 4-door, Kia Telluride and Nissan Murano were deemed merely 'marginal' in the tough new test. Only two models — the Mazda CX-9 and Volkswagen ID.4 — earned a "Good" rating in every test category.  Interestingly, the Jeep Wrangler would have scored a 'good' rating if it were equipped with side airbags for the rear seating positions. It would likely be an engineering challenge to equip its removable top and/or doors with airbags, but the lack of that safety feature allowed the head of the rear passenger dummy to hit the vertical support of the top. Otherwise, the Wrangler scored good ratings across the board. The new Ford Bronco, which makes more allowances for side-impact safety, has not yet been tested.  The popular Hyundai Palisade and Kia Telluride SUVs stand out in the test with 'poor' ratings for driver pelvis injuries. The Nissan Murano, a vehicle last redesigned for the 2015 model year, was the only vehicle tested that received a 'poor' rating for its structure and safety cage. Videos of the tests of 12 of these 18 SUVs can be found on the IIHS' YouTube page.

VW and Renault end talks to develop affordable EV, sources say

PARIS/BERLIN – Volkswagen has walked away from talks with Renault to jointly develop an affordable electric version of the Twingo subcompact car, three sources familiar with the situation said, in a setback for the EU carmakers' efforts to fend off Chinese rivals. The collapse of negotiations could mean the German carmaker may have to go it alone in developing its own affordable EV. Renault will continue designing its electric Twingo, scheduled to hit the market in 2026. Both had hoped that sharing the work would cut costs that represent a key hurdle for European carmakers in the face of cheaper cars from China. Volkswagen broke off discussions mainly because Renault had wanted to build the car in one of its plants at a time when VW is seeking to fully utilize its European production network, one of the sources said. Ampere, Renault's EV operation overseeing the Twingo program, declined to comment. A spokesperson for Volkswagen also declined to comment on the talks between the companies but said that the German carmaker was still studying its options on cheap EVs. The companies "did not succeed in finding an agreement" after several months of negotiations, one of the sources said. Another source said that an agreement had been very close, but that VW walked away from the talks and has decided to develop its own car. The sources declined to be named because the talks are confidential. VW sources said a decision on the EV plan is expected within weeks. Thomas Schaefer, CEO of the Volkswagen brand, has said he wants to launch a lower-priced EV by 2027. The second source said Renault would continue work on the Twingo without VW, but also remained open to other partners, for instance from the alliance with Nissan and Mitsubishi. It is also a blow for Renault CEO Luca de Meo's hopes for greater cooperation between European carmakers against their Chinese competitors, akin to Airbus which has stakeholders and operations across European countries. The VW-Renault tie-up for the Twingo could have formed the "basis" of an Airbus for autos, the second source said. China's automakers, the world's top EV producers, are making fast inroads in the European market, pressuring incumbents like Renault and VW to cut costs and speed up the time it takes to bring a new model to market. European automakers are aiming to produce smaller EVs that sell below 20,000 euros ($21,686) to help them compete with Chinese brands like BYD.
