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.

2019 Mazda Miata officially announced with 181 horsepower

It turns out the rumors and leaks are true. The 2019 Mazda MX-5 Miata will indeed get a slight performance increase. This fall, the car's naturally aspirated 2.0-liter inline-four will make 181 horsepower and 151 pound-feet of torque. That's a 26 horsepower and 3 pound-feet bump over the 2018 model. It may not sound like a lot on paper, but consider the fact that it's a nearly 17 percent increase in power in a car that weighs just 2,332 lbs. When the current ND generation debuted a few years back, the Miata actually took a slight hit to power. It was offset by a sizable weight loss program, but it didn't stop people from making a fuss. These days, it's not often that a newer model actually loses power compared to the outgoing car. The new car now makes roughly the same power as the old turbocharged Mazdaspeed MX-5 from 2004. Peak power for the 2019 model comes at 7,000 rpm while peak torque arrives at 4,000 rpm. That's 1,000 more and 600 fewer revs respectively. The Miata's redline is now 7,500 rpm, up from 6,800. It should make the car feel more lively through the rev range and should drop the car's 0-60 mph time back under 7 seconds. The 2019 model only weighs 7-pounds more than the outgoing model, so it's essentially a non-issue. In order to get the extra juice, Mazda engineers did some significant work to the engine's internals. Piston mass has been reduced 27 grams while the connecting rods are down 41 grams. The exhaust system and inner exhaust manifold have been modified to reduce pumping losses by 30 percent. The intake and fuel injectors have been changed, too. A new dual-mass flywheel replaces the single-mass unit. This should help better manage engine vibrations and responsiveness. Lastly, the final drive ratio has been increased from 3.454 to 3.583. Other gear ratios remain unchanged. There are other minor but welcome changes for 2019. The steering wheel now telescopes, a boon for drivers with long legs. The doors are easier to open and feature revised door stops. The cupholders and seat levers have both been updated. Finally, there are new 17-inch wheels and a new brown canvas soft top. How all these changes will affect the car remain to be seen. While many people have been clamoring for more power, some of us here at Autoblog feel the Miata may lose some of its current character with such a significant shift in power and torque. Either way, we're as excited as ever to get behind the wheel. Related Video:

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
