2016 Mazda MX-5 Miata gets 25 percent fuel economy boost

Just days after revealing full pricing and specs for each trim level of the 2016 MX-5 Miata, Mazda is spilling the beans on the roadster's fuel economy. As it turns out, the numbers show an impressive boost over the previous generation. All 2016 Miatas in the US are equipped with a 2.0-liter four-cylinder that makes 155 horsepower and 148 pound-feet of torque. With a six-speed manual, the EPA estimates fuel economy of 27 miles per gallon city, 34 mpg highway and 30 mpg combined. Buyers choosing the six-speed automatic, which is a $1,075 option (that you should absolutely not choose), are expected to get 27 mpg city, 36 mpg highway and 30 mpg combined. Compared to the previous-gen model with a six-speed manual, these latest numbers represent a 25-percent improvement in mileage. The boost in economy for the Miata likely comes from a variety of sources. Underneath the hood is one of Mazda's latest Skyactiv engines, and the loss of around 150 pounds from the last gen helps too. Production of the latest version of the famous roadster is already underway, and they should start arriving at dealers in the late summer. 2016 MAZDA MX-5 MIATA FUEL ECONOMY IMPROVES DRAMATIC 25 PERCENT VERSUS OUTGOING MODEL 24/04/15 - Mazda's Flagship Roadster Highlights Improvements Displayed by SKYACTIV Technology - IRVINE, Calif., April 24, 2015 -- Lighter, quicker and more nimble than its predecessor, the 2016 Mazda MX-5 Miata demonstrates the power innovation can have when re-engineering a roadster from the ground up. In addition to all of the aforementioned improvements the 2016 MX-5 has, fuel economy can now be added to the list, with MX-5 achieving an EPA-estimated 27 mpg city/34 mpg highway/30 mpg combined when equipped with the standard SKYACTIV-MT six-speed manual transmission (EPA-estimated 27 mpg city/36 mpg highway/30 mpg combined when equipped with the six-speed automatic). This performance represents a 25-percent increase in fuel economy versus the 2015 MX-5's EPA-estimated fuel economy when paired with the outgoing model's available six-speed manual transmission, highlighting the benefits of SKYACTIV Technology. "SKYACTIV Technology is more than a catchphrase for Mazda; it's a total effort to increase efficiency, improve performance, safety and technology and instill each Mazda vehicle with a directness and responsiveness that's unmatched in the segments in which our vehicles compete," said Jim O'Sullivan, president and CEO, Mazda North American Operations.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

NHTSA urges owners of recalled Takata airbag vehicles to take immediate action

The National Highway Traffic Safety Administration and the Department of Transportation are taking the unusual step of issuing a followup press release urging owners of certain recalled vehicles "to act immediately" to fix their cars and trucks. The problem in question concerns the repair campaigns for rupturing Takata airbag inflators issued in June and covers a long list of models from Toyota, Lexus, Honda, Acura, Mazda, BMW, Nissan, Infiniti, Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac.
While NHSTA doesn't specifically say why the recall is vital in the new release, Toyota's own explanation in its newly announced renotification campaign earlier today sheds some new light on the topic. According to the Japanese automaker, in testing, Takata found a possible link between the rupturing airbag inflators and high humidity. NHTSA is advocating that all owners pursue repairs immediately if they haven't already done so already. This is especially crucial for those drivers especially in Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii because of the humid conditions there.
We don't need to tell you how dangerous an inadvertent airbag deployment could be - even in a stationary vehicle - but adding to the Takata issue is fears that the deployment could lead to shrapnel being sprayed into the cabin.
