Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

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.

2019 Mazda3 Hatchback AWD Premium Second Drive | Gushing about an exceptional car

The 2019 Mazda3 Hatchback is quite simply one of the best cars I've ever driven. During my week with one, specifically a range-topping Premium package version for $31,335, I struggled to come up with bad things to say apart from elements like rear visibility and back seat headroom that are directly related to its distinctive, avant garde design. That's an acceptable tradeoff in my book. So many of the new 3's elements can serve as a measuring stick for other cars. Not just its specific compact hatchback/sedan class, but all other cars, period. I had the Mercedes CLS 450 at the exact time, a car I deeply appreciate and that cost $69,000 more, and yet it was a struggle to decide which I wanted to drive. Perhaps not surprising given the 3's history, but the measuring stick is set first by the handling. It dances between corners with composure and feedback that you just don't get in cars any more ͖ let alone at this price point. This is a car you feel through your butt, your heels on the floor and your hands on the wheel. Everything is just so right. And it should be noted that I came to this conclusion before remembering that Mazda switched to a cheaper, less sophisticated torsion beam rear suspension for this latest model. Perhaps you can tell the difference driving 10/10ths at a test track, but in the real world, I certainly didn't notice or log a complaint. Grip is superb. Even when the tires gave way a bit on my mountain road evaluation route, there was only a bit of squealing and it resolutely whipped itself through hairpins with shockingly little understeer for a front-drive-based car, helped no doubt by its all-wheel drive system. It would be interesting to see how much understeer the front-drive versions allow, and whether AWD is mitigating torque steer given the 3's not-insignificant power. As it is, the 3's standard 2.5-liter four-cylinder produces 186 horsepower and 186 pound-feet of torque, which is substantially better than virtually every other base engine in the segment. Its throttle response should be copied by everyone, as should the steering. OK, maybe not Porsche, which I keep finding myself drawing comparisons to whenever experiencing a new Mazda. Take that as the compliment it seems to be. I'd also like to note that the 3 has a six-speed automatic transmission rather than an easily confused eight-, nine- or eleventy-speed unit. Or a damn CVT.
