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:

Graffiti artist Banksy turns Mazda Protege into warfare commentary

British street artist Banksy, who currently resides in New York City for its high pedestrian traffic and plentiful hiding spots, recently took his stencils and spray cans to a truck trailer and an old Mazda to make a commentary about war, according to a video report by Newsy.
Part of the canvas, a late-1990s Mazda Protege, is a sub-$3,000 used car at best, but we're sure having Banksy's art sprayed onto it has greatly increased its value, as it did to a piece at a Former Packard plant in Detroit a few years ago. The same goes for the trailer, which looks like it would be right at home attached to a U-Haul rental truck.
The graffito, painted in the Lower East Side of Manhattan, was accompanied by a link to some disturbing audio from a controversial 2007 military video leaked by Wikileaks in 2010. Head on below to watch the video report, and be sure to visit Banksy's website if you want to see the painting with the audio (listener discretion advised).

Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.
