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.

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

The 2018 Mazda6 also snags top IIHS safety rating

The Insurance Institute for Highway Safety is one of two organizations that issues important safety ratings. To get to IIHS's Top Safety Pick rating level, the 2018 Mazda6 not only had to ace a bunch of difficult crash tests, it also must have headlights that meet a strict test as well. Its stablemate, the CX-5 crossover just received the even higher Top Safety Pick+ rating. Both must be equipped with optional adaptive headlights to achieve these ratings. The rationale is, many crashes happen at dusk or in the dark, and an outsized number on unlit roads. While almost all modern headlights outperform the dim, unfocused sealed beams of the past, IIHS says that government regulations aren't doing a good enough job of ensuring real-world performance. Adaptive headlights turn with the front wheels, helping out a lot in IIHS's tests on illumination in sharp and gradual curves. Related: How the 2018 Mazda6 stacks up to its competitors in the midsize sedan segment The Adaptive Front-Lighting System is only available in the Grand Touring Reserve and Signature trim levels, meaning that you'll have to upgrade to those fancy versions to get it. It'd be nice if Mazda allowed even lower-trim buyers to add this as a stand-alone option, but for now that's not how it works. Fancy, safer headlights or no, we love the new Mazda6, especially the turbocharged version. It's one of the most fun sedans around. And, according to IIHS, now one of the safest.
