Porsche Boxster Spyder to get GT3's 4.0-liter flat six?

It's been a merry-go-round the past few months, the rumormill focused on what will power the next Porsche Boxster Spyder. First came hearsay of a flat-six going into the special edition of a model line known for its turbocharged four-cylinder engines. Then came tattling that the flat-six in question was the naturally aspirated, 4.0-liter from the 911 GT3. A couple of weeks ago we wrote " we'd be surprised if Porsche packed anything other than a turbocharged flat-four under the skin." But Autocar has a new report that, indeed, a downtuned version of the 500-horsepower 4.0-liter from the GT3's rump will move to the Boxster Spyder's midsection. The Autocar piece follows a Wheels magazine article from last November, and the prediction isn't outrageous. When Car and Driver reviewed the last Boxster Spyder, it wrote, "the hand-me-down six comes from the older 911 Carrera S, not to be confused with the new turbocharged 3.0-liter flat-six that powers the refreshed 911." If we can believe a recent report from Automobile about the 992-series 911 due later this year, the same thing is happening: The 991.2-series GT3 bequeaths its powerplant to the smaller sibling, and the 992-series GT3 moves to a 3.8-liter, twin-turbo flat-six with around 550 hp. Autocar quotes Andreas Preuninger, the Porsche engineer leading the development of all of these wunderkinds, saying of the Boxster earlier this year, "Natural aspiration is one of our main USPs. ... [We] think we can achieve throttle response and immediacy a little bit better with an atmospheric high-revving engine than any kind of turbo." We'll guess that means, by inference, that the GT3 is about to age out of naturally-aspirated university. The limited-edition Boxster Spyder might carry the torch with the 4.0-liter, with output somewhere around 430 hp. The Cayman GT4 could do the same. Or, who knows, an evolution of the 375-hp, 3.8-liter flat-six in the previous Boxster Spyder might burble out of left field. We expect to see the Boxster Spyder late this year. Until then, we'll wait to see what the merry-go-round says next time the Zuffenhausen horse comes around.

Motorweek looks back at the Pontiac Aztek

The Pontiac Aztek has earned a position as this generation's ultimate, automotive punchline. Even other execrable models like the Yugo or Mustang II probably get more respect these days just out of their sheer quirkiness, but the Aztek remains a joke. Fortify your mind for what's coming, though, because the much-maligned Pontiac might not be quite so atrocious, at least according to MotorWeek's latest Retro Review video. MotorWeek calls the Aztek, "GM's first true crossover vehicle," and it's amazing to think of the hated model as a progenitor of one of the most popular segments today. While admitting that the looks are polarizing, John Davis and company actually come away pleased with the Aztek's utility. They praise that there's a ton of room in the back, and the interior is packed with useful features like a removable cooler in the center console and radio controls in a cargo area. The show is even impressed with how the Pontiac drives and throws around accolades like "nimble" and "pleasant." After seeing the Aztek leading the pack on lists of the worst vehicles of all time for years, listening to it get such effusive praise is actually quite jarring. Could we all be so wrong? No, there's absolutely no debate that this is still a hideous automobile. However, MotorWeek asserts a complete reversal of the generally perceived wisdom about the early CUV. While unexpected, thinking about such an abhorred model in a different way is a cool experience. Check out the video for a different take on the Aztek.

Fiero-based Zimmer Quicksilver was objectively terrible, but we'd totally drive it

Now here's something you don't see everyday. It's listed in our classified ads as a 1986 Pontiac Fiero, but as you can see, that description is a bit misleading. In fact, it's a Zimmer Quicksilver, which was indeed built atop the guts of a mid-engine Fiero coupe but was heavily modified by the Zimmer Motorcars Corporation at a facility in Pompano Beach, Florida. And the one you see here actually seems to be a pretty decent deal for a highly unusual car. We're not sure what was a more popular starting point for kit and custom cars in the 1980s and 1990s, but it would have to be either the Fiero or the vintage air-cooled Volkswagen Beetle. Fiero-based machines usually mimicked the design direction of any number of highly desirable Italian stallions, most commonly, we'd guess, the Lamborghini Countach. The Quicksilver is an altogether different animal, with over a foot of extra wheelbase added in front of the A-pillar to make for a dramatic, long and low silhouette that somehow still only has barely enough room for two passengers in its leather- and wood-lined interior.

A stock 2.8-liter V6 engine from General Motors is mated to a three-speed automatic transmission that sends 140 horsepower and 170 pound-feet of torque to the rear wheels. Period road tests found the 0-60 run took a little over 10 seconds, which is terrible today but wasn't all that bad for the mid '80s. Best we can tell, only around 170 Quicksilvers were made between 1984 and 1988, which are, not coincidentally, the same years that Pontiac produced the Fiero. The 1986 Zimmer Quicksilver you see here is priced at $18,495 and shows well under 30,000 miles on the odometer. There aren't a lot of Zimmer Quicksilvers currently for sale for us to compare, but the ones we did find that had sold within the last few years suggest a little under $20,000 is a reasonable asking price. It could be a fun and offbeat addition to the garage, and if nothing else, you're not likely to see another one at your local car show. Related video: This content is hosted by a third party.
