Next Mazda MX-5 Miata to weigh a ton(ne), literally

Looking at recent spy shots of the fourth-generation Mazda Miata, it's obvious this sporty little roadster will grow in size compared to the current model, but it's also going on a diet. At the Tokyo Motor Show, Auto Motor und Sport sat down with Mazda executive Kiyoshi Fujiwara, who gave a little more insight into the Miata's redesign.
Fujiwara said that they're aiming for a curb weight of a tonne (metric ton), which is 1,000 kilograms or right around 2,200 pounds, for the next-generation Miata. This would make the roadster at least 300 pounds lighter than the current NC Miata, but still about 200 pounds heavier than the original NA.
There is no indication as to how Mazda will go about removing that much weight from the bigger car, but with as popular as the power retractable hard top (PHRT) model is on the current car, the new Miata may ditch this feature to lose its weight. Improving the power-to-weight ratio appears to be a key goal of the Mazda team, so we also wouldn't be surprised to see a more powerful engine underneath the longer hood.

Mazda LM55 Vision Gran Turismo reshapes a winning form [w/video]

In the history of endurance racing, there's only ever been one Japanese automaker to win the famous 24 Hours of Le Mans, and as you might have guessed, that was Mazda in 1991 with the 787B – which was, incidentally, the only one ever to win the race under rotary power, or really anything other than a conventional piston engine. That racing success is something Mazda can be proud about, even over two decades later, and it's a badge of honor the automaker is revisiting with the LM55 prototype you see here. Only instead of unleashing it on the Circuit de la Sarthe – or really any actual race track – the Mazda LM55 Vision Gran Turismo is bound only for PlayStation. The latest addition to the Vision Gran Turismo lineup, the LM55 takes inspiration from the aforementioned 787B but gives it a modern KODO design theme. The result is pretty stunning, taking a more radical approach than the Skyactiv Prototype the company is fielding in the United SportsCar Championship or even the dearly departed, head-turning Furai concept. But unlike that diesel prototype and the Wankel-powered 787B, Mazda hasn't specified any kind of novel powertrain for the LM55, fictitious or otherwise - saying only that it has "advanced drive train technology that offers the epitome of power, efficiency and durability and the result is an exceptional power to weight ratio exceeding that of most cars in its class." Just what that class would be we'll likely never find out, but if you don't have a PS3 loaded with GT6 (or, for that matter, even if you do), you can scope out the virtual action in the slideshow above and the rather Christmas-y video below.

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.
