Mazda2 successor to ride atop shortened CX-5 platform

Mazda, looking to make the most of its new, lightweight Skyactiv vehicle architecture, will allegedly use a version of the CX-5 crossover's platform to underpin its next-generation Mazda2 hatchback, according to a report from Just-Auto.com. Of course, the Mazda2 is a much smaller vehicle than its larger CUV stablemate, so some serious chopping will no doubt be in order when it comes time to engineer the replacement for the company's smallest hatch.
Currently, the CX-5 and the sleek new Mazda6 share many of the same platform components, and this architecture will already be scaled down to support the next-generation Mazda3 sedan and hatchback, which will debut later this year. Just-Auto.com states that all of Mazda's remaining front-wheel-drive vehicles will eventually switch to reworked versions of this Skyactiv platform, including the replacement for the larger CX-9 crossover.
Also of note, Mazda will reportedly be switching to shorter, four-year lifecycles for its vehicles. This means that the newly launched Mazda6 will be replaced for the 2016 calendar year, with a refresh coming sometime in 2014. That said, vehicles with platforms supplied by other automakers (like the upcoming MX-5 Miata replacement that will share its underpinnings with an Alfa Romeo product) will not necessarily follow this four-year rule.

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.

Mazda and Isuzu to collaborate on a new pickup truck

After decades, Mazda has finally untangled itself from its relationship with Ford. The last vestige of that partnership is the BT-50, a rebadged version of the global Ford Ranger pickup truck. Once the BT-50 ends production, Mazda has announced that it will collaborate with Isuzu to develop its next generation of pickup trucks. The BT-50 was co-developed with Ford's Australian division. In their current iteration, the BT-50 and its Ranger twin were never on sale in the United States. Mazda's last pickup in the US was the B-Series, itself also a rebadged version of the old Ford Ranger. Isuzu pulled out of the US passenger vehicle market in 2009, although it still sells commercial vehicles here. Isuzu, continuing a long and complicated relationship with General Motors, co-developed the diesel engine that currently powers the Chevrolet Colorado and GMC Canyon. In select markets, Isuzu sells a rebadged version of the Colorado as the D-Max. Details on the Mazda/Isuzu tie-up are scarce. A single press release simply says "Isuzu will produce next-generation pickup trucks for Mazda, based on Isuzu's pick-up truck model." This isn't the first truck collaboration between the two companies. Since 2004, Mazda has sold the Titan, a rebadged version of the Isuzu Elf commercial truck. The Elf is sold in the US as the Isuzu N-Series. Those in the US hoping for a new competitor in the midsize-truck segment shouldn't get their hopes up for the new truck. There are currently no plans to bring them here. There is hope, though, that Ford will bring the Ranger replacement stateside sometime in the next few years.
