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?

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises. You can check out the full press release below. You can also read the full study on the Consumer Reports site, or scroll down for a short video recap.

Porsche wins the 2015 24 Hours of Le Mans

The question going into this year's 24 Hours of Le Mans was whether or not the Porsche 919 Hybrid would be able to combine its qualifying pace with race reliability. After battling neck-and-neck with Audi's R18 for most of the race, the answer is a resounding yes. Not only did Porsche drivers climb the first two spots on the podium, they did so without any major mishaps on track. This win is the first overall trophy for Porsche since 1998. Audi previously won the last five races, and 13 of the last 15. Corvette also returned to the winner's circle, with the No. 64 C7.R taking winning the GTE Pro division. The victory is the first class win for Corvette since 2011. KCMG won the LMP2 class in ninth overall. With 45 minutes to go the No. 98 Aston Martin crashed out of first place in GTE Amateur, giving the class win to SMP Racing's Ferrari and second place to the Patrick Dempsey Racing Porsche 911 RSR. For the full list of official results, click here. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. For most of the race, the battle at the top went back and forth between the two German manufacturers. An tire puncture in the No. 7 Audi gave up the lead to Porsche, and moments later a crash forced the No. 8 into the garage. But a three-minute replacement of the front and rear bodywork kept the Audi in contention. As the race wore into the night, Porsche maintained a slightly faster pace than Audi. Nick Tandy took the lead on Lap 253 early Sunday morning, and car No. 19 never gave up the top position. The win is the first for all three drivers of the No. 19 – Nico Hulkenberg, Earl Bamber, and Nick Tandy. A lap behind in second was the No. 17 Porsche. The Audis fought reliability problems late in the race but still finished third with the No. 7 R18. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. As the Aston Martin cars dropped away, the lone Corvette Racing entry took over, followed by a charging AF Corse team Ferrari 458 Italia. The Corvette and Ferrari continued to trade places in the final hours until gearbox trouble forced the No. 51 Ferrari out of contention. It was eventually passed by the other AF Corse car, No. 71. Nissan experienced all the pain of a first-year effort with its front-wheel-drive GT-R LM Nismo.
