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.

This GTO-El Camino mashup is the muscle truck of our dreams

There were a hell of a lot of great muscle cars in the mid-1960s, from the baroque Dodges and Plymouths of the earlier part of the decade to the wild big boys like the Boss 429 and Olds 442 W30. Right in the middle of the decade, two of the most iconic of the bunch emerged — the Pontiac GTO and second-generation Chevy El Camino. And this one is a 1964 Chevy El Camino with the heart and face of its GTO cousin, and dubbed the El Chieftain GTO. It's currently for sale at RM Sotheby's Auburn auction, with no reserve status or estimate listed. This looks like a product that Pontiac could have sold at the time — its builder, Ron Lindeman, did an excellent job making it look like a factory product, right down to the taillight strakes inspired by the GTO. It's powered by a 389 — a Pontiac motor that was actually found in period GTOs, but sporting a single four-barrel instead of the sexy Tri-Power setup. It is, however, equipped with a Hurst four-speed manual and the grille badge to prove it to bystanders. Even the interior is made up to look like a GTO. We wish there was more of a description of the build in the listing, but if you love it, do us one better and buy the thing and invite us to poke around it. We are very much in love with this muscle-truck mashup.

MotorWeek's 80's GM muscle coupe roundup includes Regal GN and Monte Carlo SS

Even with just four brands in the family, General Motors still represents a performance powerhouse. Between the Chevrolet Corvette Z06, Camaro Z/28, Cadillac CTS-V and ATS-V, The General can still deliver plenty of thrills. The 1980s, though, saw the brand go even crazier with performance. While the Camaro and Corvette were still around back in the day, GM had a number of other interesting performance offerings. The Bowtie was complemented by the long-deceased Monte Carlo SS, while the now-defunct Pontiac and Oldsmobile offered the Grand Prix and thumping 442, respectively. And Buick, which isn't short on performance with its Regal GS and Verano Turbo, offered a much more serious vehicle, in the form of the Grand National (not to mention the Darth Vader-spec GNX). MotorWeek, in its hugely entertaining retro flashbacks, looks back on these three long-lost GM performance icons, and it's just as good as you might expect.
