Mazda's Skyactiv-X power and efficiency ratings released in Europe

Mazda's long-awaited Skyactiv-X engine is finally headed for production, though not yet for the United States. The Japanese automaker says "various European countries" will get access to the unique engine in the Mazda3 starting this fall. Still, the announcement is relevant to the rest of us because we now have official power levels and fuel efficiency numbers that we can use to compare the Skyactiv-X with other engines offered in the compact Mazda. First, the power. According to Mazda, the 2.0-liter Skyactiv-X makes 178 horsepower and 165 pound-feet of torque. By way of comparison, the 2.5-liter Skyactiv-G engine currently used in the Mazda3 here in the States makes 186 hp and 186 lb-ft of torque. Sure, it's a little less powerful, but note that the displacements don't match and remember that the real reason the Skyactiv-X exists is to reduce fuel consumption. And that brings us to the Skyactiv-X's combined rating of around 53.5 miles per gallon (converted from liters per 100 kilometers). That's around 8 mpg better than the 2.0-liter engine that comes standard in Europe. Before we go any further, it's important to note that these numbers represent official figures for the European NEDC combined cycle, which means they are not directly comparable to the ratings we'll get from the United States EPA. Our official ratings will almost certainly be lower. With that disclaimer out of the way, the 2.5-liter Mazda3 scores a combined 30 mpg here in the States. The obvious unanswered question is when the Skyactiv-X might actually come to America. And the unfortunate answer is that we don't know. Mazda has yet to make an official decision on timing for the U.S market's launch of the engine, but as soon as we know, so will you.

Meet our new long-term 2016 Mazda MX-5 Miata Club!

We have a new Miata! For a year! And yeah, we're excited about it. This adorable roadster was added to our fleet over a month ago, but we've just now stopped driving it long enough to tell you about it. You can watch our unboxing video for this new long-termer above. (Spoiler alert: The car in the box is a Miata.) Then read a little more about which options and features we chose and why. What we got We chose the mid-line Club model because it's the only way to get the suspension with Bilstein shocks, the limited-slip differential, and a shock-tower brace. Club also includes an appearance package with a front air dam, side sill extensions, a rear bumper skirt, and a ip spoiler for the trunk. We chose Ceramic Metallic paint because it's white and silver and awesome all at once. The only option we chose is the Brembo/BBS Package. In addition to the upgraded brake system and 17-inch wheels alluded to by the title, this package adds Mazda's advanced keyless entry – you can unlock the doors and start the car without taking the key-thing out of your pocket. The MSRP for the car is $32,835. What we skipped The Grand Touring trim (too fancy), the automatic transmission (too few pedals), and extra-cost red paint (not ceramic enough). Grand Touring adds lots of convenience stuff like rain-sensing wipers and auto climate, some active safety systems, and leather. We wanted the upgraded chassis instead, and we' were trying to save some (hypothetical) money. Why we got it Because it's a Miata, and we like fun. The plan is to drive the bleep out of it for a year and report on the experience along the way. We'll take it to a track or two, keep the top down as far into winter as possible, and then slap some snow tires on it to continue . Maybe at a slight angle relative to straight-ahead at times. We'll see. If you have questions about this car, leave them in the comments below and we'll address as many as we can during the coming months. Miata! Related Video:

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.
