2015 Mazda3 finally pairs 6-speed manual with larger engine

With all of the hype and anticipation surrounding the 2016 Mazda MX-5 Miata, the Japanese brand was able to sneak another driver-oriented model into its lineup. The company's spec page for the 2015 Mazda3 hatchback and sedan have been updated to list the Skyactiv-G 2.5-liter four-cylinder as finally being available with a six-speed manual transmission, in addition to the previous six-speed automatic. The automaker had promised the row-your-own gearbox with the bigger engine back when it first announced the new Mazda3, but it waited a model year to actually put the combo on sale.
According to Mazda's specs, the manual gearbox trims 40 pounds off of a hatchback or 54 pounds off of a sedan in s Touring and s Grand Touring trims. However, shedding that weight doesn't necessarily boost fuel economy. The six-speed hatch is rated at 26 miles per gallon city and 35 mpg highway, compared to 27/37 for the automatic. The manual sedan is rated at 25/37 city/highway mpg, versus 28/39 with the auto. Buyers can save a little money by opting for the manual, though. Regardless of body style, it's about $1,050 cheaper than the automatic.
Autoblog reached out to Mazda and learned that the 2.5L 6MT models started hitting dealers in August. The 2.5 wasn't initially available with the stick because, "We had to prioritize engineering resources and the 2.5L 6MT was not a high priority combination. Globally, smaller engines are preferred in terms of sales," a Mazda spokesperson explained via email. The automaker also notes that Austrailia will probably be the only other market outside of North America to get the six-speed gearbox with the larger engine.

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.

Better as a coupe | 2017 Mazda MX-5 Miata RF First Drive

The sun can kill you. It'll also make you hot and sticky and smelly. It's a real nasty thing despite, you know, making virtually all life on Earth possible. Now, apparently, despite these risks, there are those who enjoy driving around in their car being slowly baked alive by our local star. It's insanity, really, and that's not even mentioning the indignities your hair suffers at the merciless force of the wind. So convertibles, then, who needs 'em? Just take the Mazda MX-5 Miata. Wonderful little car, barrels of fun, but wouldn't it be better off with 100 percent less sun? Besides keeping your dermatologist out of business, a solid roof would also lead to less wind noise, greater structural rigidity, and better safety for the vampire population. Nothing but Ws on the board. Alas, the 2017 Mazda MX-5 Miata RF is not the ideal solution to this perfectly sane line of reasoning. It is not the BMW M Coupe or Porsche Cayman of Miatas. It's more like the 911 Targa of Miatas, although since its rear window lowers, the most accurate analogy would be the Honda Civic del Sol of Miatas. Feel free to put that on a billboard. Admittedly, it's a pretty neat bit of engineering and design, and despite the incredibly flattering comparison above, it is accurate to describe its overall look and concept as unique. RF stands for "Retractable Fastback," which is an on-the-nose description. With the entire roof mechanism in place, it does indeed resemble a fastback in profile. From a rear-three-quarter view, that fastback is revealed instead to be buttress panels with a longer deck and a verticalish window placed between them. The Ferrari 575M Superamerica would be another point of reference, but the Miata RF is far better realized. It's particularly impressive how Mazda's designers managed to carefully reshape the Miata's rear quarters to fit and conceal the buttresses' cut line. From most angles, there's no indication that they're anything other than contiguous with the rest of the car. The little black panels that look like darkened windows at first glance are less successful, but they're also clearly necessary to create the desired buttress look and to conceal the roof mechanicals beyond. Ah yes, the compact mechanicals that make the fastback retractable and subject you to the sun's wrath.
