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 details diesel prototype at Daytona test

Diesel has without a doubt become the dominant fuel in the modern era of endurance racing. The 24 Hours of Le Mans has been won under diesel power for the past eight years running, as has every race in the FIA World Endurance Championship since its inauguration in 2012. Yet there will only be one diesel prototype entered in the top tier of the new Tudor United SportsCar Championship this year, and it belongs to Mazda.
The last Japanese manufacturer to win at Le Mans outright, Mazda has been gradually working its way back up the endurance racing ladder once again, following the example set by Audi with diesel power. Last year it campaigned a competition-spec Mazda6 Skyactiv-D in the GX class of the Grand-Am series, but rather than simply port over the existing racer into the new series, it's fielding a new prototype instead, just as it promised a couple of months ago. And now that prototype has hit the track for the first time, prompting Mazda to release its basic specs for the first time.
Tentatively referred to simply as the 2014 Mazda Prototype, the purpose-built racecar is testing this weekend in the Roar Before the 24, the official test session at Daytona that kicks off the racing season. It packs a 2.2-liter SkyActiv-D engine that's based heavily on the production version but tuned to produce 450 horsepower and 580 pound-feet of torque in race trim. Power is channeled through a six-speed sequential transmission from Xtrac, carbon brakes from AP and 18-inch racing slicks from Continental. With the Daytona-spec aero setup, it'll top out at around 186 miles per hour.

Mazda2 with extended-range hybrid rotary tech shown

Every story dealing with a new rotary engine from Mazda lands in a different place on the matrix of possibilities between "Coming soon!" and "Never gonna happen!" In 2011 it was speculated that the rotary engineering program would be shut down with the demise of the RX-8, in 2012 the program was still alive and taking lessons from the SkyActiv engines, in August 2013 a Mazda insider said a rotary engine called 16X would be here in two years, in November the CEO said the only way we'd ever get a new rotary is if Mazda could sell 100,000 of them per year. Meaning that, for the moment, you can forget about it.
And yet, last month Mazda was putting journalists in a Mazda2 RE Range Extender, an electric car using a 0.33-liter rotary to power its lithium-ion batteries when the charge runs down. With a 75-kilowatt, 100-horsepower electric motor turning the front wheels, the Wankel generator and its 2.6-gallon gas tank living under the trunk double the range of the electric-only Mazda2 to 250 miles.
There's been talk of using a rotary to assist an alt-fuel vehicle for at least seven years, with Mazda pairing an electric motor with a rotary that ran on gas and hydrogen in a Mazda5 in 2007. Since then, almost all of those stories debating its return or demise also spoke of the oddball motor's advantages, such as compact size and ability to run on various fuels, as an aid in an unconventional powertrain.
