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.

2019 Mazda CX-5 fuel economy takes a hit with new turbocharged engine

We learned all about the 2019 Mazda CX-5 last week, and now we've discovered fuel economy for its new 2.5-liter turbocharged engine. Unsurprisingly, it gets slightly worse fuel economy than its naturally aspirated counterpart. The 2019 turbo crossover, which only comes in all-wheel drive form, gets 22 mpg city and 27 mpg on the highway. Front-wheel drive CX-5s with the naturally aspirated 2.5 liter net you 25 mpg city and 31 mpg highway — all-wheel drive drops 1 mpg in both categories. For a little comparison, the turbocharged engine makes 250 horsepower and 310 pound-feet of torque on 93 octane gasoline, while the non-boosted engine makes 187 horsepower and 186 pound-feet of torque. You're definitely taking a hit in fuel economy, but the gain in power might be worth it, since the decrease isn't that terrible. Cars in its price and power range with all-wheel drive have comparable fuel economy. The Ford Escape with the 2.0-liter turbo is rated at 20/27; Chevrolet's Equinox with the 2.0-liter turbo is 22/28 and the VW Tiguan gets 21/29. There isn't really a clear winner in fuel economy for this much power when you look around the segment, but Mazda's engine is half a liter larger than everyone else. This translates to better torque than most of its competitors, but Mazda manages similar fuel economy. Also similar to many of these decked-out compact crossovers is the new high price of the Mazda we wrote about before. You won't be getting in to the turbocharged CX-5 for any less than $35,865. If you wanted a bigger Mazda like the CX-9, its fuel economy figures aren't significantly worse than the CX-5. Front-wheel drive versions are rated 22/28, and it drops 2 mpg in each category for all-wheel drive. The updated 2019 CX-5 should be coming to dealers soon.

2020 Mazda6 starts at $24,920, $200 more than 2019 model year

Mazda increased the price of all five trims of the 2020 Mazda6 by $200. The entry-level Mazda6 Sport starts at $24,000 before $920 destination charge ($965 in Alaska), for a total of $24,920. The only changes for next year are a new key fob likely copying the black and shiny metal unit from the Mazda3, and a new Signature badge likely in the form of the elemental "Sg" pulled from the CX-5 Signature model. The three Premium Paint choices carry over, with the same prices: Snowflake White Pearl Mica for $200, Machine Gray Metallic for $300, and Soul Red Crystal Metallic for $595. Prices of the other four trims run:  Mazda6 Touring $27,580 Mazda6 Grand Touring $30,620 Mazda6 Grand Touring Reserve $33,120 Mazda6 Signature $36,220 We're awaiting word on the arrival of all-wheel drive and the 2.2.-liter turbodiesel fitted to the CX-5. In the CX-5, that engine makes 168 horsepower and 290 pound-feet of torque. An AWD Mazda6 showed up in paperwork filed with the National Highway Traffic Safety Administration in January 2018, spy shots of a diesel-powered sedan followed in May that year, and Mazda mentioned the oil-burner again in April this year. For the time being, power for the 2020 Mazda6 will continue to be sent to the front axle through a six-speed automatic — Mazda eliminated the six-speed manual for the 2019 model year. The Sport and Touring trims come with a 2.5-liter four-cylinder that makes 187 hp and 186 lb-ft. The Grand Touring, Grand Touring Reserve and Signature raise that to a turbocharged 2.5-liter four-cylinder with 227 hp on 87 octane gas, or 250 hp on 93 octane, and 310 lb-ft.
