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.

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.

This is what a 1,200-hp twin-turbo 4-rotor looks like in a Miata

We've seen the diminutive Mazda MX-5 Miata swallow plenty of big engines, but New Zealand drifting ace "Mad Mike" Whiddett is roaring into where-no-man-has-gone-before territory. Wanting to replace his 515-horsepower "MADBUL" RX-7 and its twin-turbocharged, three-rotor 20B engine, his new ride is an NC-series Miata with four rotors and twin Garrett turbochargers courtesy of Pulse Performance Race Engineering. It is called "RADBUL," and expected power at standard boost is 1,200 hp, but the builders at Pulse Performance think it will get up to 1,500 hp at full boost. And yes, that exhaust exits through the hood. Four-rotor engines are actually popular - builds are detailed on forums like this one from 2007 and this one from 2008, this UK company or this Canadian company will sell you one complete - but they're usually being prepped for an RX-7. Mad Mike's choice of a Miata for this enterprise makes this about as extreme as you can get, short of throwing it into a Mazda R360. You can watch Mad Mike tell the story of the build in the video, and check out the first and second installments about the build on the Red Bull site.
