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.

Sorry, rotary fans, Mazda's RX Vision probably won't happen

Mazda is doing a lot of things the right way in this age of beige-ness. It just crammed a turbocharged inline-four into the improved CX-9, a bold move unto itself, and one that should also be heartening for Mazdaspeed fans. Wouldn't that engine make for a swell Mazdaspeed3 or Mazdaspeed6? There's a reasonable ray of hope there, but not necessarily a guarantee. The RX Vision, though, is a pipe dream. Mazda is smart to keep the rotary dream alive. It's smart to keep developing it in back rooms and to keep the idea on the public's mind. Credit where credit's due: Mazda has solved some of the stickiest issues the rotary engine has, through savvy engineering and perseverance. We've seen promising patent filings for the Skyactiv-R engine, which is supposed to be found in the RX Vision concept. Mazda uses every opportunity to remind us that development is continuing and that the company would love to bring a rotary-powered sportscar to production. I believe it. But the RX Vision is just a design study. And there are some harsh realities about rotary engine emissions and fuel economy standards that are difficult for modern piston engines to achieve without expensive componentry. Emissions and fuel economy are both bugbears of the rotary, in case you've forgotten. And that explains Mazda's interest in running rotaries on hydrogen, but down that road lie infrastructure challenges as daunting as making a gasoline-powered rotary burn as clean as one of Mazda's Skyactiv piston engines. All this is meant to put Mazda's recent comments to Top Gear in context. Mazda's design director, Kevin Rice, spoke to TG at the Concorso d'Eleganza Villa D'Este, and was waving Mazda's rotary flag quite enthusiastically. "In the back rooms at Mazda, we're still developing it," Rice said, "and when the world's ready to buy another rotary, we'll be ready to provide it." I'd like that to be a comforting statement, but given the realities of fuel economy and emissions regulations and Mazda's position in the market, it seems like a hollow platitude. "When the world's ready" is just another way of saying "when we solve the fundamental issues with this engine layout, and there's an unambiguous market study that shows we can build these cars and make a profit, we'll consider it." That seems like a lot of "ifs". Perhaps Mazda does have a clean-burning, efficient, cheap-to-produce rotary running on an engine dyno in Hiroshima, and it's prepping an RX-9 for the next auto show.

Jay Leno brings a rotary-powered VW Beetle to the garage

It takes something really unique or inventive to pique Jay Leno's interest. His show, Jay Leno's Garage, has featured everything from concours-worthy classics to completely custom, home-built machinery. How do you get Leno to feature one of more than 20 million Beetles on his program? Stick a turbocharged rotary engine under the hood. The Beetle's owner, Mario Markakis, swapped the car's stock flat four-cylinder for the Wankel engine from a 1990 Mazda RX-7 Series 5 Turbo. The engine's 250 horsepower are fed through a reinforced version of the Beetle's stock four-speed transmission. That's about five times the original engine's output. It works well, with the car putting down some impressive times at the drag strip. Markakis did most of the work to the Beetle in his garage. In addition to the engine swap, he's modified the car's brakes, suspension, and interior. Check out the video to hear all the details of this custom Wankel-powered Volkswagen.
