2016 Mazda MX-5 Miata first in-car observations

We've had few days to digest the all-new 2016 Mazda MX-5 Miata since the roadster was first revealed on Wednesday evening when we offered you our first impressions. Since that time, we've gone back and looked at the car a number of times in person here in California, and we've even seen it briefly run under its own power (okay, it was more of a saunter). What we didn't get the chance to do at the reveal, however, was sit inside the car. We've since been able to remedy that, and while we haven't been allowed to drive the new roadster, we do have some initial in-car impressions to share with you.
First, the location and feel of the major controls is quite excellent. The three-spoke steering wheel is an MX-5 specific item - it's not shared with any other Mazda. That's vital, because others would likely be too big in diameter or have the wrong rim thickness. The wheel's redundant controls seem to be well laid out and the airbag boss is very small. The column tilts, but unfortunately and somewhat inexplicably, it still doesn't telescope.
Pedals are well-spaced, and the six-speed manual has the same short throws and positive engagement that we've come to know and love.

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 considers expanding Takata recall nationwide

Vehicle recalls have come in force recently. Honda expanded its front driver's side Takata airbag inflator recall nationwide to cover an estimated 5.4-million vehicles, and the National Highway Traffic Safety Administration added 19 notices to its database covering safety campaigns dating back to October. It looks like there could be one more to add to the list soon because Mazda is considering a possible nationwide expansion of its own inflator repairs. A company spokesperson tells Reuters that there is no decision yet when to actually make this nationwide expansion of the driver's side inflator recall official, and the company isn't sure how many vehicles may be affected. Mazda just expanded the scope of its Takata inflator recalls to additional regions earlier in December. The move took its total number of units in need of repair from around 65,000 under the earlier NHTSA estimate to 86,773, according to the company. So far, the automaker's US campaign has included the 2003-2007 Mazda6, 2006-2007 MazdaSpeed6, 2004-2008 Mazda RX-8, 2004-2005 MPV and 2004 B-Series pickup.
