2015 Mazda2 spotted on the road

When Mazda unveiled the Hazumi Concept at the 2014 Geneva Motor Show, our excitement for the next Mazda2 increased considerably. The Hazumi looks to retain much of the driving character that makes the current 2 one of the very best cars in its segment while infusing it with more aggressive styling. Of course, when the 2 arrives, it won't look exactly like the Hazumi. That's why these spy photos are so important.
This is our very first look at the next-generation 2, and although the Hazumi influence might be difficult to discern, thanks to the swirly camo, it's still there. The grille shape and the headlights are very similar in shape to the items shown on the concept, while the camouflage disguises the shape of the greenhouse, which looks somewhat like the Hazumi.
What we can't see, though, is under the hood. That's where our spies come in, reporting that a pair of 1.5-liter SkyActiv engines will see action in the tossable 2. The former, which we'll almost certainly see in the US, is a gas-powered mill found in the Euro-spec Mazda3. In the larger 3, it produces 99 horsepower and 111 pound-feet of torque, which is broadly similar to what the current 2's 1.5-liter pumps out. The other engine, a 1.5-liter SkyActiv diesel, probably won't be making the trip, although we'll continue to hope.

Mazda hard at work on Skyactiv 2 engine technology

As 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.

Mazda2 sedan debuting in Thailand this month?

Mazda is reportedly set to introduce a Mazda2 with a four-door sedan body. Unlike the upcoming CX-3, which is debuting at the upcoming Los Angeles Auto Show and is almost certain to be sold in North America, this other version's chance here are a bit more mysterious.
According to The Bangkok Post, the Mazda2 sedan will make its word debut at the Thailand International Motor Expo on November 28, and the traditional five-door hatch will be there as well. Both body styles will be built in Thailand with diesel engines and will be the first vehicles to adhere to the country's eco-car rules for oil-burners with a SkyActiv 1.5-liter diesel that will make 105 horsepower.
At this time, there's no indication whether the new sedan might also be sold in the US, but we're not holding our breath - remember, the previous Mazda2 sedan never made it Stateside, either.
