Long Road Racing will build you the Miata that Mazda won't

One of the frustrating things about new cars today is that many features are exclusive to this trim level, or that package. Even the enthusiast-friendly Miata has many restrictions how you can configure one, which can make choosing one a bit tricky. You can't have the cheapest one or the leather-clad one with a limited slip differential, for example. And adding aftermarket parts on your own runs the risk of voiding your warranty. Long Road Racing, however, has a possible solution for creating the ideal, warranty-covered Miata. You may not be familiar with Long Road Racing, but you probably heard about one of its most-publicized products, the MX-5 Cup car. The car was developed by Mazda with the intention of creating a global spec series, and Mazda reports that about 140 of the cars have been sold so far. Every single one of those cars went to Long Road Racing to be specced out for racing before reaching their customers. So the company is familiar with the car, and has applied its expertise to its "Ultimate MX-5" program. The way the program works is, once you've purchased a 2016 or 2017 Miata, you can send it to the company to have it customized to your needs. The company has an extensive list of parts to choose from, all of which have been selected by the company to work well together. But if you need something outside of its offerings, or just need help choosing from the list, you can get in touch with the company to discuss how best to achieve your goals. Long Road Racing will also customize any trim level of Miata, and can even create a Miata Mazda didn't offer. For instance, you could have a Grand Touring with the leather interior, but also with the limited-slip differential and Brembo brakes from the Club model. All of these parts are fully warrantied by Long Road Racing for the length of the OEM warranty, and they don't void the factory warranty. We had the opportunity to try out a car customized by Long Road Racing at the M1 Concourse track in Pontiac, Mich. The car was there to sample alongside some of the MX-5 Cup cars as well as several of Mazda's stock road cars to drive on course. The road-going Long car started as a Grand Touring model, and it retains its heated leather seats and automatic climate control.

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.

Mazda development chief discusses future rotary platform

The switch can again be flicked from "The Rotary Engine is Doomed" to "The Rotary Engine Lives!" Mazda is re-tooling the once nearly forgotten rotary to work as a range extender for hybrid vehicles, with a chance for it to do even more than that. The latest information sounds rather promising for those still holding out a candle for the rotary. Mazda's powertrain development chief, Ichiro Hirose discussed future rotary plans with the Australian Drive at the CX-30 crossover's launch. Hirose told Australia's Drive that Mazda is currently working with a very flexible and efficient rotary hybrid platform that doesn't necessarily come with the heavy emissions and fuel consumption baggage the rotary engine has earlier been saddled with. Hirose calls the rotary-based solution "XEV," referring to its adaptability. "It has the generator function and also it can be used to provide the drive force to give you traction. [...] Because the rotary engine is compact in terms of its packaging size [and] if we should choose to do so we can have the generator, rotary engine and electric motor all in one [driveline] because of the small packaging." The result is an electrified platform that could be made to work as a mild hybrid, series hybrid or a battery electric vehicle with a rotary range extender (if given a plug), depending of the required implementation. It's as if Mazda had a slider to adjust the balance of using a rotary engine and using electric power, to make the platform more of a jack-of-all-trades. Hirose explained: "If you reduce the other way around it could be a pure battery-electric, using really the rotary engine as a range extender and, according to the balance, you can even provide something akin to the series hybrid that is providing the drive force. [...] So, we are looking at a wider coverage and scope. Based on this architecture it allows us to do that, to explore the huge range of applications we can have with the rotary." The platform would also be flexible when it comes to meeting various stringent emissions standards. To be able to sell XEV-based vehicles globally would mean introducing a certain setup for one region and one for another, keeping in mind when the rotary power would kick in and how. While Hirose keeps the question open whether these vehicles would make it for sale in the United States, he says Mazda would be able to make them pass U.S regulations. "I'm just saying that — theoretically — if we were to introduce it in the U.S.
