From Maseratis to rental cars | Autoblog Podcast #511

On this week's podcast, Mike Austin and David Gluckman are in a huddle room (again), because the studio was already taken (again). We talk about the all-wheel-drive Dodge Challenger GT (again), as well as the Jeep Wrangler, Maserati Levante, Miata RF (again), and then David waxes poetic on mediocre rental cars (or similar). The episode wraps up with the traditional doling out of Spend My Money buying advice, with some input from an S2000 owner on advice discussed last time. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. (If you record audio of a question with your phone and get it to us, you could hear your very own voice on the podcast. Neat, right?) And if you have other questions or comments, please send those too.

MotorWeek finds nice things to say about the 1993 Ford Probe

This latest in MotorWeek's series of Retro Reviews continues its recent trend of remembering the massive glut of sports coupes that hit the market in the '90s. While vehicles like the Mitsubishi 3000GT, Mazda RX-7, and Ford Mustang all enjoy solid reputations down to this day, the 1993 Ford Probe, well... doesn't. As you'll soon see, though, the show's opinion suggests the coupe's second generation isn't really all that bad. Turns out they just weren't particularly sporty. Ford and Mazda developed the Probe together, and the Japanese company supplied both the base 115-horsepower 2.0-liter four-cylinder and the 164-hp 2.5-liter V6 in the GT trim. The original's pseudo-angular look gave way to a much smoother shape for the second generation. Of course, pop-up headlights remained, which were a design hallmark for many of this era's sports coupes. After driving it, MotorWeek proclaims the Probe is "a winner" and considers the handling a "delight." That's not a big surprise, considering that in those days, a car had to be really bad not to get a decent review from Television's Original Automotive Magazine. However, the show hints at some of the reasons the coupe isn't so well remembered today. Even the GT reportedly suffers from soft springs and lots of understeer, which sounds like exactly the opposite anyone hoping to drive the coupe enthusiastically would want. To sum it all up, we're sure you're just as happy as we are that Ford went back on its initial plan to shelve the Mustang in favor of the front-drive Probe. Related Video:

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.
