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.

Suzuki recalls 2 million cars globally

Suzuki is recalling two million vehicles across the globe, including a number of Chevrolet Cruze sedans that it builds for General Motors, because the ignition switches may begin to smoke. None of the Cruzes being recalled were sold in the US, though. This recall is limited to the Japanese, European and Australian markets. In Suzuki's home market, 1,873,000 vehicles are being recalled, including the Cruze and a number kei cars built for Mazda (the Carol and AZ-Wagon), as well as the automaker's own Alto, Wagon R and Swift. Affected vehicles were built between 1998 and 2009. The remaining 133,000 vehicles include Cruzes and other Suzuki products sold in Europe and Australia. There have been no reports of injuries or accidents due to the 67 reported incidents, all of which come from the Japanese market, a Suzuki spokesperson told Automotive News. Related Video:

2018 Mazda6 refresh takes the car further upmarket

The 2018 Mazda6 is, on the surface, a very mild refresh. The front grille has been given more depth, and the fascia is generally cleaned up a bit, putting the design inline with the new CX-5 and future Mazda products. The interior has been given the same treatment: cleaned up and modernized. But throughout the car, some important updates under the skin make the 6 a more compelling product, and one that continues the company's push upmarket. The biggest change has already been partly revealed, and that's the addition of Mazda's turbocharged 2.5-liter four-cylinder. It's the same engine found in the CX-9, and Mazda has now revealed it will make the same 250 horsepower and 310 pound-feet of torque with premium fuel. The engine will also happily accept 87-octane, in which case the engine will make 227 horsepower. Though the addition of this engine is welcome, we're a bit disappointed to learn that it will only be available with a six-speed automatic transmission. If we're lucky, we might see Mazda add a manual option, since when Mazda launched the current Mazda3, the larger 2.5-liter engine was initially only available with an automatic. But try not to get your hopes up too high, either. The good news is that Mazda will continue to offer a manual transmission as well as an automatic with the base, naturally aspirated 2.5-liter four-cylinder. This engine will now feature cylinder deactivation, as will the 2018 Mazda CX-5. This system will shut off the cylinders on each end at cruising speed to improve fuel economy. Official fuel economy ratings for both engines have yet to be released. Aside from the powertrain, Mazda says it has made a few other mechanical improvements. The suspension has been retuned, and the steering rack rigidly mounted to the chassis to improve handling. Thicker sheet metal for the rear wheel wells, thicker trailing arms, and a bevy of braces have also been added in order to reduce noise for a more refined driving experience. The interior has also been updated for more refinement, particularly on the new Signature trim model. The sleeker interior design on all Mazda6s is joined by redesigned seats Mazda says are more comfortable. Those seats are now available with optional ventilation. A windshield-projected heads-up display, adaptive cruise control that can bring the car to a stop and resume accelerating, as well as an instrument panel with a configurable 7-inch screen are other options.
