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.

What a 181-horsepower 2019 Mazda MX-5 Miata means for us, and you

Last month, we reported on a VIN filing dug up by Road & Track that showed that the 2019 Mazda MX-5 Miata's 2.0-liter Skyactiv-G engine would get a power bump, from 155 to 181 net horsepower. As for how the 2019 Miata would make that extra power, we heard rumors it'd utilize a new cylinder head allowing higher revs, accounting for that extra power. Now we have what appears to be a leaked document from Mazda Canada showing exactly where that extra power comes from. According to the document posted at Miata.net (registration required to see the image), Mazda will alter camshaft lift and valve size on both the intake and exhaust side, fit freer-flowing exhaust, and smooth and enlarge the piping on the air intake side. There are also internal engine modifications: lighter pistons with lower crowns for better swirl in the combustion chamber, lighter connecting rods, and a crankshaft balanced for higher-RPM operation. All those extra revs mean extra vibration and noise, so Mazda will ditch the single-mass flywheel for a "low-inertia" dual-mass flywheel – which will attempt to find a nice balance between DMF damping action and SMF directness. Overall, it's a pretty serious engine revision with some driveline changes that will heavily affect the driving characteristics of a fantastic driver's car. Contributing Editor James Riswick and Senior Editor Alex Kierstein, both well versed in Miatas past and present, are here to analyze what this could mean for the little roadster. James Riswick: I don't know much about them lighter crank combustion rods, but I for one welcome the news of more power to the Miata. The jump from 155 to 181 seems like a very prudent Mazda-like thing to do, accomplishing that task through various aforementioned technical wizardry as opposed to slapping on a turbocharger, exclaiming "yee-hah" and calling it a day. Alex Kierstein: That's true. I'm wary of additional power, but you do make a good point that at least this is the right way to do it. Going all-motor will keep the bright responsiveness of the engine intact. But higher revs might make power delivery peakier. Frankly, I'd be ok with moving the torque and horsepower peaks up a bit in the rev range, making it a bit more work to access the engine's sweet spot. The dual-mass flywheel should also help if low-end torque suffers, so less stalling in traffic. JR: Did wonders in the 911 and 718s.

Fiat 124 Abarth Spider spied, may get Alfa 4C power

We've long been excited to see, hear, and drive the car that results from the in-process Fiat-Mazda partnership. The Italian brand has had access to the excellent 2016 Mazda MX-5 Miata on which to base its own roadster, and the fruits of that labor will soon ripen. Spied here is not only the ensuing Fiat 124, but a hotter Abarth tuned version of the spider. At least, that's what we're hoping. Our spy shooters indicated that the car seen here not only sounded more aggressive than 'standard' 124 mules seen previously, but that it also accelerated away from their long lenses with a smartness. The 124 Spider is already rumored to make use of the 1.4-liter turbo I4 that makes 160 horsepower in the Fiat 500 Abarth, and this version may have a still-more-powerful engine. Another tell about the added output are the quad tailpipes in place of the lesser car's set of two. There's no hard evidence to support exactly which engine might be under the 124's hood, however. It's possible that the 1.7-liter turbo from Alfa Romeo 4C could be in play – with its 237-hp output – as the 124 was originally going to wear an Alfa badge. If that were to happen, however, the Fiat would almost certainly get a dual-clutch transmission instead of the purer manual box. In any event, more details about the car will no doubt crop up closer to the expected reveal this fall. Related Video:
