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.

AMC Trans Am Javelin SST, an ultra-rare underdog, is up for auction

Among the rarest of the American muscle cars that went racing in the early Seventies — cars including the Camaro Z/28 and the Boss 302 Mustang — the 1970 AMC Trans Am Javelin SST may be the most hard to find, and among the most valuable. Only 100 units of this unique Javelin were produced, and one of them is up for auction at the Mecum event in Dallas on September 20. The Trans Am Javelin was fashioned in a patriotic livery of tricolor paint — red, white and blue — and arrived after the American Motors Corporation had decided in 1968 to compete in the Trans Am racing series against Ford and General Motors. The company's chief driver, Mark Donohue, would dominate the 1971 season, taking seven wins in his Javelin AMX and that yearÂ’s SCCA Trans-Am Championship. AMC took the trophy with 82 points, well ahead of Ford's 61, Chevrolet's 17 and Pontiac's paltry 7. The example listed for auction came equipped with a 390-cubic-inch V-8 engine with 325 horsepower at 5,000 rpm and 420 pound-feet of torque, power steering and brakes, dual exhaust, BorgWarner four-speed manual transmission and Hurst competition shifter. Its “ram induction system” sealed a chamber around the air filter so that cool air from the functional hood scoop would be funneled into the intake. This JavÂ’s factory price was $3,995 — a mere $32,000 or so in today's money, though it was expensive by the standards of the time. The 100 Trans Ams were among 19,714 Javelin units built in 1970, so they started out rare, and today the surviving examples are highly collectible, if and when they come up for sale. No bid estimate is available yet. Related Video: Motorsports Chevrolet Ford Pontiac Auctions Automotive History Racing Vehicles Classics

Junkyard Gem: 1968 Pontiac Catalina sedan

During the late 1960s, General Motors ruled the American car landscape, growing so dominant that the federal government considered antitrust action to break up the company. The General offered sporty Corvettes and muscular GTOs and rugged pickups and opulent Fleetwoods, sure, but the fat part of the sales numbers came from the bread-and-butter full-sized sedans and coupes, which boasted superior engineering and modern-looking styling; in 1967 alone, the Chevrolet Division moved 972,600 full-sized cars, and that's not even counting the 155,100 full-sized Chevy station wagons that year. Pontiac, Buick and Oldsmobile sold the same big cars with division-specific engines and bodywork, and they flew off the showroom floors. For 1968, the entry-level full-sized car from Pontiac was the Catalina, and I've found an example of the most affordable version of the most affordable big Pontiac for 1968, discarded in a northeastern Colorado wrecking yard about 50 miles south of Cheyenne, Wyoming. A '68 GM full-sized coupe, convertible, or even a four-door hardtop might be worth the cost and effort of a restoration, but a no-options base-trim-level post sedan with rust and plenty of body filler just won't get many takers these days. Like so many vehicles that sit outside for decades on the High Plains, this one is full of rodent nests. I wouldn't want to work on the interior of this car without a respirator and a lot of work with a shop-vac, because hantavirus is a significant danger in these parts. Alfred Sloan's plan to offer a stepladder of prestige for GM buyers, in which your first new car was a Chevrolet and you moved up through Pontiac, Oldsmobile, and Buick until you became sufficiently prosperous for Cadillac ownership, worked brilliantly for decades. In 1968, the Catalina was a notch above its Impala sibling on the Snob-O-Meter, with the sedan starting at $3,004 (about $22,600 in 2019 dollars). In fact, the V8-equipped 1968 Chevrolet Impala sedan listed at $3,033, and the Oldsmobile Delmont 88 went for $3,146, so the lines were beginning to blur between the relative positions of the lower-end GM divisions by this time. The base engine in the 1968 Catalina was a 400-cubic-inch (6.5 liter) V8 rated at 265 horsepower and enough torque to tow an aircraft carrier.
