The Mazda MX-5 Miata and saving a marriage

I've had the privilege of knowing Zach Bowman – former Autoblog scribe, now penning great things over at Road & Track – for nearly a decade. We met at the Detroit Auto Show when we were both relatively new to the business, and joked about how someday, we'd work together and eventually conquer the world as big shots in the industry (we're still figuring that last part out, by the way). Thus, I was thrilled when Zach joined Autoblog in 2010, just a couple of months after I was hired, and was equally saddened when I learned he'd be leaving us. Zach is someone I'm proud to call a colleague – nay, a friend – and I've enjoyed the voice he's brought to this line of work. I tell you this on a personal level because Zach has just published what you could arguably consider his most heartfelt piece of automotive work to date. It's a charming, emotional story about his relationship with his wife, and how they, like so many young couples, learned to make marriage work through the many ups and downs found in any solid relationship. I call this "automotive work" because Zach intertwines this tale into a story about driving his 2006 Mazda MX-5 Miata across the country, his wife by his side, learning about love and life from the cockpit of a two-seat roadster. I can honestly say it's one of the best things I've read in a long while. Rather than continue to wax poetic about Zach's latest piece, I'll let his own words speak for themselves. Head over to Road & Track to read the full piece.

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.

Junkyard Gem: 1981 Mazda RX-7

The first-generation Mazda RX-7 was sold for the 1978 through 1985 model years, and for decades you'd see and hear these nimble little sports cars buzzing around American streets. Then, well, the apex seals went out, or owners tired of a 2,400-pound car that drank fuel like an Eldorado, or the floor pans were eaten by the Rust Monster... and then nearly all of them were gone. Enough of them remain, however, for a steady trickle to show up with depressing regularity in self-service wrecking yards. Here's a pretty solid '81 that I found in a Denver yard last month. The 12A Wankel engine in this car made 100 hp and 105 lb-ft of torque, which was very good for 1981 (considering that you could buy a new Camaro with a 115-horsepower V8 that year). The $9,385 RX-7 looked like an especially good value when compared to, say, the $11,299 Datsun 280ZX or the $8,997 Fiat 124 Sport Spider, being much lighter on its feet than the former and much quicker than the latter.
