Autoblog readers meet the 2016 Mazda MX-5 Miata [w/video]

Mazda dropped off a 2016 MX-5 Miata at our office this week with only two stipulations: don't break it, and don't talk about driving impressions until 3:01 AM Eastern on Monday, June 1. Easy enough. But rather than hold our notes until the embargo lifts, we decided to do something different. By now, you've no doubt read all there is to know about the 2016 Miata, including our review of the Japanese-spec car with the 1.5-liter engine that isn't coming to North America. You know it's smaller than the outgoing NC model. And you know that, at 2,332 pounds, it's nearly as light as the original. But what you, and we, didn't know, is what Miata owners think about the 2016 model. The MX-5 group is incredibly enthusiastic, and they love their cars. Hell, they love each other's cars. So we gave them an opportunity to not only get together, but to get an up-close, informal look at the ND Miata outside of an auto show, several months before it officially goes on sale. Here's what we did. Cars And Coneys Anyone who's familiar with the Woodward Dream Cruise in metro Detroit has no doubt heard of Athens Coney Island in Royal Oak, MI. It's an iconic place, known for its top-notch coney dogs, quick service, and the fact that, on pretty much any warm-weather weekend, you can find cool cars in the parking lot. We called the folks at Athens, told them about our Miata meet-up, and they were immediately on board with coneys, soda, and coffee for our gathering. We first published our meet-up info late last week, and sent the details out on our social media channels, as well. But without any formal RSVP system, we had no idea how many people would show up. And since Mother Nature decided to provide us with gray skies and chilly temperatures, we figured a lot of would-be attendees opted to bail at the last minute. Needless to say, we were surprised to see several Miatas already lined up in the Athens parking lot when we arrived with the ND at 4:40 PM, 20 minutes before the listed 5:00 start time. No one kept a formal count, but our best guess is that something like 50 or 60 cars showed up over the course of three hours. Some folks stayed the whole time, some people only stopped by for a quick cup of coffee. A couple people drove long distances to attend – a few Miatas hailing from southern Ohio, and many from western Michigan. We had a huge mix of cars, too.

MotorWeek proves '90s were awesome with Supra, Stealth, RX-7, Corvette, 968, 300ZX comparo

Oh, the heady days of 1993, back when the Clinton Presidency was just getting underway, and it seemed like every hot new rock band was coming out of Seattle. Sports cars in the US had finally shaken off the shackles that slowed them during the '70s and '80s, and you could buy any number of legitimately quick vehicles again. MotorWeek recently went digging into its archives to find this six-model test from 1993 showing off some of the best semi-affordable performance coupes that money could buy at the time, and it's priceless.
Featuring the 1994 model year Toyota Supra in twin-turbo guise and MY 1993 versions of the Porsche 968, Nissan 300ZX TT, Mazda RX-7, Dodge Stealth R/T Turbo and Chevrolet Corvette LT-1, MotorWeek definitely covered all of the bases. One thing that might surprise younger readers is these cars' performance. The video only provides 0-60 acceleration times, but several of these vehicles would still be considered pretty potent today - over 20 years since going on sale. The Supra is especially impressive, hitting 60 miles per hour in just 5 seconds. Even today, that's nothing to sneeze at.
Given their performance potential and still-attractive looks, it's amazing that some of these coupes are old enough to drink now. The progress of interior design and safety equipment in the intervening years is pretty shocking, though. In most of these models, having two airbags is touted as a big deal. Scroll down to watch a Throwback Thursday blast from the past about some of the '90s best sports cars.

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.
