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.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.

Mazda Vision Coupe | Tokyo Motor Show's big, sensuous 4-door

Mazda has been making a lot of noise recently about not giving up on the rotary engine. Enough that we started to think it might show a new epitrochoid-engined concept at this year's Tokyo Motor Show. But the brand is nothing if not surprising. Have you driven a CX-5 or a CX-9? Have you noted the real-world fuel economy in a Mazda3? Have you looked at a Miata RF? So instead of trotting out the latest in Wankel weirdness, today in its home market, the Mazda folks pulled the silk off of a stunning full-size four-door design concept, the somewhat inaptly named Vision Coupe. Known mainly for sporty and affordable small(ish) vehicles, Mazda hasn't really had an entry in this category since ... ever. Well, save for the staid and short-lived 929 of the '90s (and the rotary-powered, 7/8-scale Olds Cutlass, JDM-only Roadpacer of the '70s.) As customers flock to crossovers, it's not exactly a category brimming with vitality, at least in the American market — sales of the existing Mazda 6 are down in the States by nearly 25 percent this year, double the market average for cars. And this thing is bigger than that. But the decision is intentional and strategic in Mazda's mission to head upscale and focus on clean design — differentiators from its mass-market Japanese peers. "A big sedan has always been the symbol of a brand going premium. It's the icon of a brand," says Julien Montousse, Mazda North America's director of design. "It tells that Mazda is becoming serious in reaching that goal." Breaking even more conventions, while Mazdas generally are cohesive and well-rendered in their design, you would be hard-pressed to find one quite this sensuous. The Vision Coupe looks like an Aston Martin Rapide that has been placed in a sauna until its body-mass index has whittled down to marathoner levels, and then scalloped and stripped of any unnecessary ornamentation, save for a kind of fingerprinted whorl in its side cove. It is elemental, at once planar and burnished, with the lovely long-hood/short-deck proportions of a classic front-engine, rear-wheel-drive grand tourer. Its interior is similarly edited, doing away with the proliferating screens of other vehicles in the category, utilizing instead a digital analog instrument panel and a sophisticated heads-up display that keeps a driver focused on the road and shows just what is deemed necessary, and nothing else.
