Mazda6 GX Grand-Am racer goes where no diesel sedan has gone before

There has never been a four-door diesel sedan in the Grand-Am series, until now: The blunt, bewinged grille of the Mazda6 GX has blown right through that wall. It's said that racing improves the breed, but usually the breed has gone on sale when the racing begins. One of the unusual aspects of the Mazda6 GX, on the other hand, is that while the diesel won't go on sale to the public until later this year, it will already have tasted racing blood by the end of the day. That kind of reversal is more likely found with super coupes like the Lexus LFA and Honda NSX.
Mazda has taken class wins at Daytona's 24-hour race a whopping 23 times since 1975, most recently in 2010 with the RX-8 in the GT class. This year the Hiroshima company decided to show off its SkyActiv technology, then turned things up to eleven by opting for its SkyActiv-D instead of the more conventional SkyActiv-G gas engine to run in the new GX class. It will be joined by competitors like the Lotus Evora and Porsche Cayman in the class, nevertheless, at 2.4 liters, it's the smallest engine on the grid.
Time has not been a friend, either - Mazda said that the first five SkyActiv-D engines off the production line went to Speed Source in Coral Springs, Florida, the company that preps Mazda's race vehicles. Still, race driver Jonathan Baumarito on the #70 car said that although the engine's been on the dyno since February of last year, it's only been in the car for about a month and there have been only a couple of test days.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

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.
