GM reintroduces Tripower name in the worst way possible

The story of General Motors' use of the Tripower moniker begins way back in 1957, when Semon E. "Bunkie" Knudsen, then General Manager of GM's Pontiac division, directed his engineers to inject more performance into his brand's line of V8-powered automobiles. Fuel injection was an option, but hot rodders flocked instead to Tri-Power (marketed way back when with a hyphen), which grafted a trio of two-barrel Rochester carburetors onto a single intake manifold. A legend was born. And that legend was born of performance. At idle and when full power wasn't required, Pontiac's Tri-Power system used just the middle carburetor, which helped make the setup easier to tune. Depending on the year and model, either a vacuum system or a mechanical linkage opened up the two outer carbs, thereby switching from two barrels to six, and allowing the engine to take in more fuel and air. And it was an easy marketing win – six barrels is better than four barrels, right? Because performance! So, when news filtered in that GM has resurrected the Tripower name, those of us who grew up attending classic car shows and wrenching on old Pontiacs did a double-take. And then we all collectively sighed. Turns out that today's Tripower refers to a trio of fuel-saving measures that include cylinder deactivation, active thermal management, and intake valve lift control, according to Automotive News. And, at least for now, it applies to GM's line of fullsize trucks powered by a 2.7-liter turbocharged four-cylinder engine. We're all for saving fuel whenever possible. And we have zero say in how any automaker chooses to market its products and technologies. But, we'll offer our two cents anyway: Relaunching a storied name from the past is fine. Relaunching a storied name from the past while completely overlooking the reasons the name got famous in the first place is only going to irritate the people who remember the name in the first place. Couldn't they just call this new technology package something else?

Next-gen GMC Sierra spied with diesel power

The next generation of GM trucks is arriving soon, and we're expecting a huge leap forward over the current lineup. The Chevy Silverado and the GMC SIerra sell extremely well, but haven't done much to move the segment forward in a long time. The Ford F-150 has an all-aluminum body and turbocharged V6 power. The Ram 1500 gained a diesel and coil spring suspension. These spy shots show that diesel may be in the cards for GM. Some quick shots and copious use of flash show what is most likely a tank for diesel exhaust fluid and a diesel particulate filter, both necessary equipment for any modern diesel. It's unclear what form factor that engine will come in, though GM has a number of engines to choose from, including the 2.8-liter inline four that's found in the Colorado and Canyon, though that may be a little light duty for the Silverado and Sierra. Other rumors surrounding the trucks suggest a move to an aluminum cab while retaining a steel bed. That seems like a reasonable move for GM, even if the company was attempting to shame Ford for its move to aluminum a few years ago. Look for more news as early as the Detroit Auto Show in January.

Dale Earnhardt, Jr. puts his Callaway Corvette and '55 Chevy on eBay

Dale Earnhardt, Jr. has put a couple of his personal cars up for sale on eBay. The first is a 1955 Chevy Bel Air that Junior had reworked by Funkmaster Flex, a bit of a diversion from Flex's more common Ford efforts. Junior's ride has a replacement chassis from Jim Meyer Racing, a 434 small-block tuned by Sharioff Racing to 500 horsepower, and truly thin rubber on what appear to be aluminum billet rims with Junior's former number 8 on the center caps. The interior is all custom and painted to match the outside, and those seats have been completely reupholstered. The second car is a 1999 Callaway C12, the 18th of 19 C12s built that year and featured in a 2002 issue of AutoWeek. It joined Earnhardt's private collection in 2004. Built on the base of a C5 Chevrolet Corvette and using a lot of technical know-how from Callaway's European racing program, the BMW #287 Blue Pearl C12 had its V8 bored out to 6.2 liters and graced with Callaway's Supernatural upgrade; it also has a Callaway coil-over suspension with adjustable dampers. There's new bodywork all around, and when new it cost about $200,000. At the time of writing bidding on the Bel Air was up to $80,100, the C12 was at $63,100. The auction ends Monday morning, and the winning bidders have the option of having their prizes autographed and retrieving the keys from Dale Jr himself if they're willing to go to Moorseville, NC.
