Xcar tries to figure out what makes the Miata so great

Over the past 25 years and 3 model generations, the Mazda MX-5 Miata has shown that you don't have to be the best to be a massive success. The little, Japanese roadster has never been the absolute peak of automotive performance, but it's precise handling, good reliability and frugal running costs have helped make it a star. Autoblog recently tried to give you the experience of driving one on video, and now Xcar Films has made its own in an attempt to show what makes this droptop an icon.
As Xcar puts it, the Miata isn't the world's best sports car, but it is the world's favorite. When they were originally designing the roadster, Mazda's engineers took everything that made British droptops from the '60s great, and junked all of the stuff that made them a terror to own. The result was a car that would start up everyday with no fuss and get drivers wherever they needed to go with a huge grin on their face.
The fourth-generation Miata is imminently on the way for its September 3 unveiling, and the very early rumors indicate that Mazda doesn't plan to rock the boat too much with the latest one. It supposedly rides on a longer wheelbase and wider track but with the weight trimmed by over 200 pounds. Check out Xcar's video for a primer on MX-5 history and why the automotive world loves this little roadster.

2019 Mazda CX-5 fuel economy takes a hit with new turbocharged engine

We learned all about the 2019 Mazda CX-5 last week, and now we've discovered fuel economy for its new 2.5-liter turbocharged engine. Unsurprisingly, it gets slightly worse fuel economy than its naturally aspirated counterpart. The 2019 turbo crossover, which only comes in all-wheel drive form, gets 22 mpg city and 27 mpg on the highway. Front-wheel drive CX-5s with the naturally aspirated 2.5 liter net you 25 mpg city and 31 mpg highway — all-wheel drive drops 1 mpg in both categories. For a little comparison, the turbocharged engine makes 250 horsepower and 310 pound-feet of torque on 93 octane gasoline, while the non-boosted engine makes 187 horsepower and 186 pound-feet of torque. You're definitely taking a hit in fuel economy, but the gain in power might be worth it, since the decrease isn't that terrible. Cars in its price and power range with all-wheel drive have comparable fuel economy. The Ford Escape with the 2.0-liter turbo is rated at 20/27; Chevrolet's Equinox with the 2.0-liter turbo is 22/28 and the VW Tiguan gets 21/29. There isn't really a clear winner in fuel economy for this much power when you look around the segment, but Mazda's engine is half a liter larger than everyone else. This translates to better torque than most of its competitors, but Mazda manages similar fuel economy. Also similar to many of these decked-out compact crossovers is the new high price of the Mazda we wrote about before. You won't be getting in to the turbocharged CX-5 for any less than $35,865. If you wanted a bigger Mazda like the CX-9, its fuel economy figures aren't significantly worse than the CX-5. Front-wheel drive versions are rated 22/28, and it drops 2 mpg in each category for all-wheel drive. The updated 2019 CX-5 should be coming to dealers soon.

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.
