Weekly Recap: Diesel scandal continues to fuel VW's woes

Volkswagen's woes continued this week when it was delisted from the Dow Jones Sustainability Index and stripped of awards. Senators are also lining up to advocate for criminal and civil action against the automaker, and its consumer reputation is in tatters. Put simply, it's been another rough period for VW. Despite this, the company eked out a sales gain of less than one percent in September, though that was well behind the overall market's performance. Sister brand Audi, which sells a diesel A3, was less affected, posting a 16-percent gain in September. Revelations that Volkswagen rigged millions of diesel-powered cars around the world didn't surface until September 18, so the full sales impact of the ongoing scandal won't likely be felt until October. Meanwhile, VW's image continues to take a beating, and an AutoPacific survey found only one in 14 vehicle owners have a positive opinion of the company. Before the scandal broke, three-quarters of respondents had a positive view of VW. The survey also found 64 percent don't trust Volkswagen, though the same number believe other companies are or may also be using cheating devices to pass emissions tests. "The reputation of diesels has been severely damaged, at least for the short term," Ed Kim, AutoPacific's vice president of industry analysis, said in a statement. Despite the lingering malaise, experts believe VW will recover, just as Toyota and General Motors eventually emerged from their own high-profile controversies. "Consumers have proven through numerous recalls that they are resilient and quickly return to their buying habits," Kim said. OTHER NEWS & NOTES Mazda to reveal sports car concept in Tokyo Mazda will bring a curvy sports car concept to the Tokyo Motor Show in October. The automaker is being especially coy with the details, only releasing the dark teaser shot that you see to the right and a cryptic statement that suggests the concept "condense[s] Mazda's entire history of sports-car development into a single model." Immediately, speculation abounded this is an RX-7 and RX-8 successor, though Mazda didn't specify what engine the concept will have. Reportedly, the company is still working on rotary engines. Mazda will have a Cosmo Sport 110S on its stand in Tokyo, which pioneered rotary technology in 1967. Read into that what you will.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.
