Why Mazda’s Skyactiv-X compression-ignition engine is a smart hedge bet

Mazda has cracked the code on a compression-ignition engine, called Skyactiv-X (which utilizes SCCI, or Spark Controlled Compression Ignition). That's a neat engineering accomplishment, sure, but why is the tiny company investing big dollars in fancy tech that's frustrated the much larger companies who've investigated it? In this case, Mazda is peering into a crystal ball to consider how best to flow with a few troubling tides. One is the premature handwringing about the death of the internal combustion engine, another is Europe's swing away from diesel engines. Skyactiv-X seems, at this juncture, a hedge bet against both aspects. EV infrastructure lags massively behind our petroleum infrastructure — no shock there. Mazda claims the tech will net 20-30 percent gains in fuel efficiency over its current gasoline engines and about matching its diesel engine. And that's without any onboard hybrid tech, so that staves off the inevitable necessity to fully adopt electrification for a while — this is assuming that, at some point, it won't be practical to sell a non-hybrid or non-EV. At what date that happens is open to debate, but as I said above, technology like this kicks that decision point down the road a bit. Mazda is here translating research dollars into time, allowing its engine factories a few more years of probably profitable production of internal-combustion engines before retooling, and before somebody needs to pour a massive amount of money into a broad EV charging infrastructure to replace gas stations. None of this is happening fast enough for a wholesale transition to EVs anytime soon. So, that's one bet hedged. The next is Europe's declining interest in diesel engines for mainly health reasons. Just about a week ago, The New York Times posted an excellent primer on this issue, which is somewhat controversial in Europe. Germany's auto industry, a huge portion of its economy, is heavily invested in diesel tech and seriously opposed to proposals in Britain and France to eliminate the technology, which creates unhealthy diesel particulate emissions. The German industry is hoping Band-Aids like pollution-reducing measures will help them, but after a massive and widespread emission cheating scandal, its credibility is at a nadir. It seems like consumers have sensed which way the wind is blowing, and it has hurt sales. The NYT reports that diesel sales in Germany alone — remember, bastion and originator of diesel technology — are down 13 percent.

Recharge Wrap-up: Tesla road rage video, Mazda tests EVs vs. hybrids

A Tesla Model S driver was caught driving recklessly in a dashcam video. On Toronto's Don Valley Parkway, the driver of a white Model S can bee seen speeding along the left shoulder. Another car moves partway onto the shoulder to block the driver, who moves back into the left lane. As traffic slows, the driver pulls back onto the shoulder and speeds away. The folks at Teslarati suggest that this serves as an example of why vehicle autonomy could make the roadways safer. See the video above, and read more at Teslarati. Formula E will be broadcast live on Italy's Rai network for the next two seasons. The programming will include the live races, as well as practice and qualifying highlights, podium celebrations, interviews and other pre- and post-race coverage. "It's a great opportunity for Formula E and motorsport fans to have Rai broadcasting the live races of our series in Italy," says Trulli Formula E team owner Jarno Trulli. "It's a step forward to make the series grow and get stronger after a successful first season. I'm looking forward to cooperate with Rai and show the Italian fans what we are truly doing with our technology." Read more from Formula E. A new study links a decline in cancer risk to California's air quality regulations. The study from CARB found that cancer risk from toxic air contaminants declined 76 percent from 1990 to 2012, a time period that corresponds with regulations targeting those contaminants. Even as the amount of diesel miles driven has steadily increased, cancer risk from diesel particulate matter has declined significantly. The paper predicts that cancer risk will continue to drop as a result of controls on toxic emissions. Read more at Green Car Congress. Mazda is conducting consumer trials of hybrid and electric vehicles in Japan to gauge reception. Depending on whether hybrids or EVs prove to be more popular, Mazda will adopt one of the two types of powertrain for future production vehicles. The automaker is currently testing an electric Mazda2 against a hybrid Mazda3. While this round of testing is focused on the automaker's home market, Mazda may need to expand trials to the US in response to tightening regulations in California. Read more at Green Car Reports.

BMW tops Consumer Reports 2023 Brand Report Card

Feels like we wrote about Consumer Reports' 2022 Brand Report Car and 10 Top Picks a few weeks ago, but it was last April. So the mag is back with a ranked roster of 32 brands and 10 vehicles in four categories for your debating pleasure. Starting with the brands, last year's top three were Subaru, Mazda and BMW. This year, the Munich crew climbed two spots to win the prize thanks to "Superb road test scores and solid results in CR’s reliability and owner satisfaction surveys." Subaru narrowly fell to second, maintaining its four-year run in the top three. Mini, eighth last year, jumped five spots to get the last step on the podium. The rest of the top 10 were Lexus (up one spot from last year), Honda (down one spot from last year), Toyota (up three), Genesis (up 12), Mazda (down six), Audi (down three) and Kia (up eight). The magazine and testing outfit says its Brand Report Card "[reveals] which automakers are producing the most well-performing, safe, and reliable vehicles based on CRÂ’s independent testing and member surveys," and that "Brands that rise to the top tend to have the most consistent performance across their model lineups." Last year's top 10 had six automakers from Japan, three from Germany (giving Mini credit for England), none from the U.S. or South Korea, and five luxury brands. This year's list counts five makes from Japan, two from Germany because Porsche fell out of the top ten, two from South Korea, still none from the U.S., and four luxury brands. Buick again ranked as the best domestic, dropping to 12th after being 11th last year. The big mover was Lincoln, its 10-place jump up to 16th attributed to better reliability from the Corsair and Nautilus. Tesla's improved overall reliability saw it climb six spots to 17th. Dodge climbed one spot to 15th. Jeep got out of the penalty box in last to come second-to-last. Land Rover fell three places into the penalty spot.  CR's top 10 vehicle models The 10 Top Picks list is practically a new list. Only two holdovers made it to 2023, those being the Subaru Forester and Kia Telluride.
