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.

Should you buy a leftover 2015 or a brand new 2016 model?

One of the most common questions I get asked as a car dealer and auto auctioneer is, "When is the best time to buy a new car?" The answer is usually the time period between Labor Day and the middle of November. That's because this is when new car dealers and the manufacturers are trying to get rid of their current-model-year vehicles to make way for a small army of 2016 models. Rebates, incentives, cheap financing, and overstocks of unpopular models all help create the liquidity needed to turn the old inventory into a new set of wheels for the buying public – often at a very reduced price. But sometimes the "old" new car isn't a better pick than the "new" new car. It depends on a lot of factors, including the car in question and the differences from one model year to the next. I recently received an email from Jeff, who is interested in the Mazda CX-9 and asks whether he should buy a 2015 model or wait for the new version that will debut soon in LA. I'll use his as the example case. Length of Ownership The longer you own a vehicle, the less model year depreciation will be an issue. For example, the difference in value between a five-year-old Mazda 6 and a six-year-old version is about $1,500 according to the Manheim Market Report ($5,600 vs. $4,100). But if you look at the difference between 10-year-old and 9-year-old versions of that same vehicle, the price difference shrinks all the way down to $200. Because Jeff plans to own his new crossover for many years, the 2015 model wins in this category. View 19 Photos Rebates and Incentives The current CX-9 has a $4,000 cash incentive from Mazda. This is in part because Mazda still has quite a few left over. That $4,000 rebate for the current model is already coupled with even stronger discounts at the dealer level for those leftover 2015 models. TrueCar is showing that a loaded 2015 model can be had for $7,000 off the sticker at $28,600. You may even be able to beat that price by negotiating the deal yourself. Another thing to consider is that new models tend to be in high demand when they launch, which means that your purchase price will likely be substantially higher with the new model than it will with a leftover 2015. Again, financially speaking, this is a vote for the 2015 model. New Stuff It's also important to weigh what new features will come along with the updated model and how important they are to you.

2017 Mazda CX-9 Prototype First Drive

If you read our coverage from last week's Los Angeles Auto Show, you'll note that we were extremely fond of the new Mazda CX-9. We like the look of the thing, inside and out, and it promises to be the best-driving entry in the three-row crossover class. We agree wholeheartedly with that claim. You see, we already drove it. Full disclosure: Our test of the camouflaged CX-9 prototype you see here was short, and while we were able to get a good handle on the CX-9's basic driving dynamics, it'll take more than a 30-mile session around the outskirts of LA to uncover the finer details. What's more, these vehicles are not production ready. In fact, according to our handlers at Mazda, the CUV we tested was actually at the stage before pre-production – so basically, a pre-pre-production car. That said, all the details about the engine, transmission, suspension, and steering are "largely final." As you can see in the gallery, the cars we tested were heavily camouflaged both inside and out. As for styling, we love it – see the undisguised pictures from the LA show for more views. And as for inside, we can say leather seats of our Grand Touring model were comfortable and supportive, and the smallish steering wheel felt natural in the hand. Even in pre-pre-production state, the CX-9 was impressively quiet. An extra 53 pounds of under-floor sound deadening, thicker windows, and active noise cancellation all contribute to what Mazda claims will be "among the quietest vehicles in its class." It's worth noting that the good sounds, like the throaty, whooshy noises of the turbocharged engine, found their way into the cabin just fine. The 2.5-liter, turbocharged four-cylinder engine – Mazda's first force-induced Skyactiv engine – is an excellent piece. The 2.5-liter, turbocharged four-cylinder engine – Mazda's first force-induced Skyactiv engine – is an excellent piece. It uses a variable geometry turbocharger, which the company calls a Dynamic Pressure Turbo. Here's how Mazda explains it: Imagine a normal garden hose. Put your thumb over the nozzle, and the force of the water increases dramatically. That's the DPT at low rpms. It features three small exhaust ports to direct exhaust gases into the turbo, making for 17.4 quick-spooling PSI at low rpms. As the revs climb, a flow control valve opens up, redirecting the gases to a trio of larger ports – removing your thumb from the hose, if you will – and keeping the boost up.
