2016 Mazda MX-5 Miata first engine shot revealed
Mon, 08 Sep 2014We'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.
2014 Mazda3
Tue, 28 Jan 2014Almost by definition, affordable compact cars aren't supposed to be fun. Sure, hot hatches get our blood pumping, but not long ago, the terms "compact car" and "economy car" could safely be used interchangeably. A key exception for the last decade has been the Mazda3, a car that has consistently delivered more dynamic thrills and tactile feedback than its contemporaries. Competitors have picked up their game significantly in recent years, however, leaving the Mazda3 wanting in several areas, including overall refinement, in-car technology and cabin appointments, so Mazda went back to the drawing board to create this all-new third-gen model for 2014.
Including this redesigned 2014 model, Mazda's recent crop of new products have targeted North America's hottest non-truck segments - compact car, midsize sedan and compact crossover/SUV. Yet it might be fair to call this launch the most important of them all, as the 3 remains the Japanese marque's best-selling vehicle. While America's pool of compact hatchbacks isn't exactly deep, the 2014 Mazda3 still has a challenging road ahead of it competing against two-box compacts that include the popular Ford Focus and recent additions like the all-new Kia Forte and the still-new Hyundai Elantra GT.
Mazda hard at work on Skyactiv 2 engine technology
Wed, 08 Jan 2014As 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.
