2016 Mazda MX-5 Miata will rock 2.0L SkyActiv engine in US, 1.5L elsewhere

Let the speculation finally end - we know what will power the next-generation 2016 Mazda MX-5 Miata, and it's not turbocharged. The US model will get a SkyActiv 2.0-liter engine and six-speed manual, while models in the rest of the world have a 1.5-liter engine, confirming earlier rumors.
Unfortunately, Mazda isn't letting loose how much power either of these mills make just yet. For sake of comparison, the current SkyActiv 2.0 in the Mazda3 produces 155 horsepower and 150 pound-feet of torque, and the 1.5-liter in the UK (and elsewhere) has about 99 hp and 110 lb-ft of twist. However, the current Miata produces 167 hp and 140 lb-ft.
But fret not droptop fans. The company's brochure from the 2014 Paris Motor Show confirms, "all available drivetrains have been specially tuned for the all-new MX-5," which at least hints at the possibility of more performance. Also, even if the numbers remain untouched, the new Miata should feel even more sporting on the open road. That's because Mazda says the new model weighs in the neighborhood of 2,200 pounds; with that in mind, the 2016 car would boast around 14.19 pounds per horsepower versus 14.85 lb/hp in the present MX-5. Progress!

Mazda says 83 percent of new cars bear Skyactiv moniker

Mazda's US sales are down a little bit but the company's fuel economy is almost assuredly up. That's because its fuel-saving Skyactiv drivetrain technology is essentially taking over US vehicles sales. To the tune of about five out of every six vehicles sold, at least. While the Japanese automaker's US sales in February fell 2.4 percent from a year earlier, Skyactiv accounted for 83 percent of its sales last month. Most notably, Mazda6 sales jumped 46 percent from a year earlier, while Mazda CX-5 sales were up 72 percent. The company also celebrated the opening of its factory in Salamanca, Mexico, where it will make models such as the Mazda2 and Mazda3. The company is not resting on its fuel-economy laurels either, apparently. In January, it was reported the company is hard at work on its next-generation Skyactiv technology, which will boost fuel efficiency by as much as 30 percent by using diesel-like high compression. As it is, Mazda had the highest fleetwide fuel economy of any major automaker in the US for the 2013 model year with a 27.5 mile per gallon average, according to the Environmental Protection Agency (EPA). Honda came in second with 27 mpg. Check out Mazda's press release below. MAZDA SKYACTIV® TECHNOLOGY SETS RECORDS IN FEBRUARY - Mazda Celebrates Grand Opening of All-New Production Facility in Salamanca, Mexico - IRVINE, Calif., March 3, 2014 /PRNewswire/ -- Mazda North American Operations (MNAO) today reported February U.S. sales of 24,431 vehicles, representing a decrease of 2.4 percent versus last year. Year-to-date sales through February are down 6.7 percent versus last year, with 43,155 vehicles sold. Key February sales notes: Mazda's SKYACTIV® TECHNOLOGY accounted for 83.2 percent of all vehicle sales during the month of February. This is the largest percentage of Mazdas equipped with SKYACTIV TECHNOLOGY sold in one month, and second-best month of total volume ever with 20,245 vehicles sold. Mazda6 experienced its second-best February since 2008 with 3,945 vehicles sold, representing an increase of 46.0 percent, year-over-year (YOY). February 2014 was CX-5's best month ever with 9,353 vehicles sold, good for an increase of 71.6 percent, YOY. February was one of the most historic months for Mazda as it celebrated the grand opening of its all-new engine and vehicle assembly plant in Salamanca, Mexico.

Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.
