2016 Mazda MX-5 Miata first engine shot revealed

We've dug deep for just about every scrap of 2016 Mazda MX-5 Miata info available out of the car's California reveal celebration, but powertrain particulars have been especially hard to come by. While we still don't have engine specifications, the folks over at Autoweek have scored a nice scoop - the first underhood photos of one of the display cars.
In the image above, the ND-generation Miata is clearly shown to be powered by a Skyactiv inline four-cylinder, as expected, but its displacement remains unclear. The engine is most likely either the 2.0-liter Skyactiv-G engine offered in low-end Mazda3 and CX-5 models or the 2.5-liter Skyactiv-G found in those same vehicles' upper trims. In those iterations, the 2.0-liter generates 155 horsepower and 154 pound-feet of torque, while the larger-displacement engine nets out at 184 hp and 185 lb-ft. There is no sign of a turbocharger, a feature rumored to be fitted to at least one test mule. There has also been previous rumors of a 1.5-liter Skyactiv engine, possibly for overseas markets.
The 2.0-liter strikes us as the most likely scenario, particularly as Mazda has worked diligently to save every gram in the new car, dropping a pledged 100 kilograms (220 pounds) over the current model, even while adding content. It's entirely possible that the alleged turbo car was, in fact, a mule for the Miata's Alfa Romeo sister car, which is expected to have a wholly different powertrain. Or it could simply be a second engine option for an eventual Mazdaspeed variant, perhaps.

2020 Mazda CX-5 adds torque to the turbo engine, gets more expensive

The 2020 Mazda CX-5 is getting a little more desirable in the new model year. It’s also slightly more expensive. Most of the benefits are realized with the 2.5-liter turbocharged four-cylinder. This engine gets a small boost in torque, going from 310 pound-feet to 320 pound-feet. Horsepower stays the same at 250 horses, and the max power is still made using 93 octane fuel. We saw a similar torque gain in the 2020 CX-9. Mazda says it also added a new “Engine Harmonics Enhancer” that “tunes to the engine with a much more refined and powerful sound.” WeÂ’re guessing the turbocharged engine is going to sound just a hair better in 2020. When equipped with the turbocharged engine and all-wheel drive, the CX-5 also gets an off-road traction assist feature. Similar to the CX-9Â’s system, Mazda says “when the diagonal wheels lose traction, off-road traction assist will stop reducing the engine torque and increase the brake force on the wheels without traction.”  Mazda says all CX-5s will also take advantage of improved NVH, making the CX-5 feel a bit more premium and isolated from the road. Every CX-5 will also be equipped with MazdaÂ’s suite of i-Activsense safety features as standard in 2020, as well. This means adaptive cruise control and lane-keeping assist are both standard features now. As Mazda tries its best to move into the premium space, itÂ’s changed all the fonts on the badging and displays on the car. Although, Mazda neglected to include any photos of the new look, so weÂ’ll wait to judge on that front. The premium look and feel comes with a slightly higher price than 2019. A base Sport is $740 more expensive than last year, coming in at $26,135 after the $1,045 destination charge. The most luxurious Signature trim is just a touch more expensive than last year (by $165) at $38,100. What Mazda hasnÂ’t included in its 2020 rundown is the Skyactiv-D diesel option. WeÂ’ve reached out to Mazda to see if we can determine its fate in 2020 and will update this story upon hearing back. Update: Mazda responded to our request for comment. Since the 2019 diesel variant was on a different release schedule than the rest of the 2019 CX-5 lineup, the company isn't talking 2020 diesel yet. The company is treating it as a "future product," therefore it's not commenting on it.  We can only speculate as to what that means for the diesel CX-5, so we'll wait on official information from Mazda whenever it may come.

Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.
