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."

2016 Mazda MX-5 Miata First Drive [w/video]

Hypothetically speaking, if you blindfolded me, put me in the car pictured above, and told me to hit the road, it would have taken me maybe two minutes to figure out that I was driving the 2016 Mazda MX-5 Miata. There are just certain facets about Miata driving that have been baked into every generation of Mazda's roadster, and it makes for a symbiotic relationship between car and driver that's truly unique. Sure, I could rattle off a list of cars that come close to offering the same sort of experience, but they just can't quite capture the same intrinsic Miata magic. Mazda knows its Miata is an incredibly special machine. Listening to the company's engineers and designers talk about the development of this fourth-generation ND model is fascinating. The attention to detail is astonishing, and every single person involved in the Miata program knows that the most important goal is to keep this car as true to its predecessors' ethos as possible. It cannot just be a great convertible, or even a great Mazda – it has to be a great MX-5 Miata. But the company did not just want to improve upon the third-generation NC Miata, which has been around since 2006. They wanted to tie the ND Miata's roots back to the original NA from 1989. Back in '89, the Miata was a less-powerful, 1.6-liter model with 115 horsepower and 100 pound-feet of torque. Mazda's team said they are proud of every version of the MX-5, but it's this specific, first-generation model that the company calls the "most right" – the most true to the idea of what a Miata ought to be. So that's why, before being allowed to attack the winding roads of the Spanish countryside in the 2016 MX-5, Mazda wanted me to spend some time with a cherry example of the original NA Miata: a Mariner Blue darling that, even with some 239,000 kilometers on its clock, still felt absolutely impeccable from behind the wheel. Light, responsive, and perfectly balanced, it was the original embodiment of the harmony between driver and car that Mazda wanted in every Miata. Mazda executives said they felt the first Miata was also the right size. So they chopped off three inches on the ND compared with the NC, and put it on a wheelbase that's been reduced by six-tenths of an inch. In fact, these dimensions mean the new Miata is more than two inches shorter in length than the original, and only two-tenths of an inch taller. In this day and age of ever-expanding waistlines and footprints, it's a remarkable achievement.

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.
