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.

Drive plays Smokey, Bandit with turbo Trans Am

The modern trend for powertrains can be summed up with the simple maxim: cut displacement and add forced induction. Whether you are looking at the just-introduced 2016 Chevrolet Cruze or a BMW M3, this adage holds true. However, Pontiac's attempt at the idea goes all the way back in 1980 with the Firebird Trans Am and its turbocharged 4.9-liter V8. Drive's Mike Musto takes out a 1981 example to explain what makes this largely forgotten muscle car so special, and it certainly isn't performance. While a 4.9-liter V8 might sound like a lot in the modern world, keep in mind that only few years before the second-generation Trans Am was available with up to a staggering 7.5-liters of displacement. Turbocharging of road cars in the early '80s was quite archaic by today's standards, and the Firebird only managed around 200 horsepower with this mill. Without much go, the turbo Trans Am made up for a lack of power with lots of show. As Musto points out, the famous flaming chicken adorns practically every surface you can see on the coupe, and boost lights on the hood illuminate when the turbo is spinning. Musto still finds a lot to like about the turbo Trans Am. He even calls it "Burt Reynolds as an automobile." Find out why the coupe is so special in this entertaining clip.

Sci-fi movie Jinn features car designer, Firebird-bodied Camaro

If you're an automotive engineer being tormented by an immortal being made of fire, then wouldn't you think it best to have a custom coupe called the FireBreather for your getaway car? That's the FireBreather in the image above, adorned by the red wings that once fronted the Pontiac Firebird, running away from a black cloud of evil in a trailer for the movie Jinn.
The Jinn is eternal evil, always waiting for the chance to make things float across rooms before going on homicidal urban rampages. The FireBreather is a Gen-V Chevrolet Camaro - from the V6 to the ZL1 - that's been through Classic Design Concepts' extensive list of exterior and interior modifications, including entirely new front and rear fascias and side skirts, sway bars and springs, Pirelli P Zeroes and an available Edelbrock supercharger.
The movie - FireBreathing chase scenes and all - was shot in Monroe, Michigan. You can watch the trailer below, but since the FireBreather only get a couple of seconds on screen, you can find out more about it on Street Legal TV and its official site.
