2016 Mazda MX-5 Miata won't get power folding hardtop

Following the reveal of the 2016 Mazda MX-5 Miata, more and more details (and rumors - oh, the rumors) are coming out regarding exactly what's in store when the car finally goes on sale. Our own Chris Paukert had plenty to say about the exterior and interior, and we've now seen the first photo of the engine. But a new report from Automobile sheds even more light on the 2016 Miata - specifically, that the power folding hardtop model won't be available, at least initially.
Automobile reports that the 2016 MX-5 will only be offered with a cloth top, and an insider confirmed that the mechanism is light and accessible enough that it can be raised and lowered with one hand from inside the car. Mazda officials would not comment on the availability of a hardtop in the coming years.
That said, a hardtop Miata isn't out of the question. There will likely be some sort of fixed roof available - even as a one-piece, lift-off accessory - if only for club racing. Also, remember that the current NC Miata's hardtop is the only one on the market that doesn't take up any additional trunk space, so it's an attractive proposition for buyers. Currently, the power hardtop is only offered on the Club and Grand Touring MX-5 Miata trims.

IIHS Top Safety Pick and Top Safety Pick+ awards get tougher: Here are the latest winners

Automakers love to trumpet the accolades from the Insurance Institute for Highway Safety, but the agency keeps making its best grades harder to achieve. For 2020, it is raising the bar again, requiring a better score in the passenger-side small-overlap crash test, wider availability of top-performing headlights, and automatic emergency braking systems that effectively avoid collisions with pedestrians, in addition to its previous benchmarks. Why the 2020 criteria is harder: To be named either a Top Safety Pick or Top Safety Pick+, the required performance in the passenger-side small-overlap crash test has been raised from Acceptable to Good, meaning that the model must achieve Good ratings in all crash tests. The Nissan Rogue, for example, scored an Acceptable in the passenger-side small overlap crash, and so it loses its Top Safety Pick rating for 2020. To achieve either of the top ratings, a vehicle's automatic emergency braking system must effectively avoid hitting pedestrians as well as other vehicles. (The automatic emergency braking system can be optional, but then the award applies to the model only when so equipped.) Any vehicle whose automatic emergency braking system does not include pedestrian detection would lose its TSP or TSP+ rating for 2020, the Ram 1500 being one example. To be named a Top Safety Pick+, the model can have no variant with headlights that achieve less than an Acceptable rating (most new cars have different headlights — often LEDs — that are exclusive to upper trim levels).

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.
