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.

Edmunds ranks the best used cars for 2013

When people ask us what car we would recommend for them, it's usually not easy to answer. To make a useful recommendation we must consider which of the numerous vehicle segments fits their needs best, and then choose one of the many vehicles offered in each segment. For some people, new cars don't meet their expectations of value, because they lose so much of it the moment they are purchased and driven off the dealer lot. For them, there's always the used-car market, where great deals can be found, but cars' histories of reliability and maintenance records - and perhaps that Certified Pre-Owned warranty - become ever-important factors playing into purchase choice.
To help out, Edmunds has done us the favor of assembling a list of the best used vehicles money can buy, covering model years 2006-2011, according to what it considers the most important criteria when shopping for used autos: reliability, safety, value and availability. That means unreliable, unsafe, super-expensive or limited-edition models don't appear on the list, but instead cars from each segment that are more likely to satisfy the general population.
There are some real goodies on the list, including but not limited to vehicles such as the capable Honda Fit, the cultish Honda Accord coupe (which can be had with a 240-horsepower V6 and a six-speed manual transmission some years), and the powerful Chevrolet Corvette. While Edmunds' choice of the Volvo C70 for best used convertible baffled us at first (not that it's a bad car), it redeemed itself by stating that the Mazda MX-5 still is an unofficial top choice if you don't require more than two seats.

Mazda6 Skyactiv-D racecar gets first win at Road Atlanta

Mazda has a long motorsports history, and one that is peppered with fascinating cars. The latest chapter in Mazda's racing story has just been written, as Joel Miller and Andrew Carbonell have driven the Visit Florida Racing Mazda6 Skyactiv-D to the car's first ever victory at the Rolex Grand-Am GX race at Road Atlanta. The win marks the first ever for Mazda's diesel-burning, production-car based Skyactiv-D racer, and the first win for a diesel-powered car in a Grand-Am event.
In fact, it was a particularly good day for the Mazda Motorsports team, as a Mazda6 also picked up the third finishing spot at Road Atlanta. Director of Mazda Motorsports, John M. Doonan, said of the racecar, "We've always said that the best street cars make the best racecars, and, with more than half of the components in the race engine being shared with the street engine, this program is a solid proof-point."
SpeedSource Engineering, which helped to build the Mazda6 racer, was greatly heartened by the car's performance in just it's fourth-ever race. Owner Sylvain Tremblay called the victory, "a tribute to the thousands of hours of hard work over many months," continuing, "The normal plan with a new car is to spend the first year in development, the second year seeking race wins, and challenging for a championship in year three. We are already at our year-two status after four races. We can't wait to get to the Belle Isle course in Detroit for round five."
