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.

Junkyard Gem: 1991 Mercury Capri

Ford has gotten a lot of use out of the Capri name in the United States. First, there was the Lincoln Capri in the 1950s, followed by the Ford Capri Mk1 (which was sold by Mercury dealers in the USA but never actually badged as a Mercury). Then came the 1979-1986 Mercury Capri, built on the very successful Fox Platform and essentially a clone of the Mustang. Finally, in 1991, the Australian Ford Capri came to the United States. Here is an example of this rare car that I spotted in a Northern California self-service yard not long ago. Mechanically speaking, the 1991-1994 Capri was a Mazda 323 under the skin, complete with a member of the same B-series engine family that went into such cars as the Miata and Ford Escort. So, for a few years in the early 1990s, car shoppers who wanted a sporty Mazda convertible could choose between a Miata and a Capri. The Capri had front-wheel-drive, but could be had with factory turbocharging. These cars were reliable and fun, but had a tough time competing with the Miata in the showroom battles. You'll see the occasional example now and then, but most of the 1991-1994 Capris have met the same fate that awaits this one. Related Video:

MotorWeek finds nice things to say about the 1993 Ford Probe

This latest in MotorWeek's series of Retro Reviews continues its recent trend of remembering the massive glut of sports coupes that hit the market in the '90s. While vehicles like the Mitsubishi 3000GT, Mazda RX-7, and Ford Mustang all enjoy solid reputations down to this day, the 1993 Ford Probe, well... doesn't. As you'll soon see, though, the show's opinion suggests the coupe's second generation isn't really all that bad. Turns out they just weren't particularly sporty. Ford and Mazda developed the Probe together, and the Japanese company supplied both the base 115-horsepower 2.0-liter four-cylinder and the 164-hp 2.5-liter V6 in the GT trim. The original's pseudo-angular look gave way to a much smoother shape for the second generation. Of course, pop-up headlights remained, which were a design hallmark for many of this era's sports coupes. After driving it, MotorWeek proclaims the Probe is "a winner" and considers the handling a "delight." That's not a big surprise, considering that in those days, a car had to be really bad not to get a decent review from Television's Original Automotive Magazine. However, the show hints at some of the reasons the coupe isn't so well remembered today. Even the GT reportedly suffers from soft springs and lots of understeer, which sounds like exactly the opposite anyone hoping to drive the coupe enthusiastically would want. To sum it all up, we're sure you're just as happy as we are that Ford went back on its initial plan to shelve the Mustang in favor of the front-drive Probe. Related Video:
