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?

Corvette Stingray Convertible images mysteriously appear on web, so we add our own

It was inevitable that we'd see the 2014 Chevrolet Corvette Stingray topless at some point, but that didn't make us any less interested when a pair of supposedly leaked official images showed up on theautoinsiderblog.com last week. We posted them on our Facebook page, but held off reporting on them here until we could get a little more information.
Those images, which feature a dark red car on a sterile black studio background, supposedly first appeared on the website of diecast model maker Maisto. A Chevrolet spokesman has been reported saying that they are "not official images released by Chevrolet PR," which isn't a denial they're the real deal, but neither is it a confirmation.
Close examination of the photos suggest they could be official shots of the Corvette Stingray Convertible, and while some have doubted their authenticity due to a lack of vents (which were seen on the C7s that debuted in Detroit last week), it could be that the images are of a base model car without the Z51 package that doesn't require the extra venting and cooling.

2016 Chevy Volt arrives with 50-mile EV range, 41 mpg [w/ video]

Let's start with the numbers. The 2016 Chevy Volt will have an all-electric range of 50 miles from a new, 18.4-kWh lithium battery. It will get 41 miles per gallon (combined) once the battery runs dry and have 102 MPGe. Oh, and it has five seats, sort of. To compare, today's four-seat 2015 Volt has a 38-mile range from a 17.1-kWh battery in a powertrain that offers 37 mpg and 98 MPGe. So, across the board, there are notable improvements. Now that that's out of the way, let's talk story. General Motors will unveil the new Volt at the Detroit Auto Show later today, but it's been talking about how this new version – the first major plug-in hybrid vehicle to get a serious redo in the modern era – was crafted with reams and reams of data from first-gen Volt customers. At a preview event for journalists last week, GM executive chief engineer Pam Fletcher told Autoblog that these owners "gave us the recipe" to make the second-gen model. At the top of the request list was more range (check), more "fun-to-drive" behavior (check?) and a smoother and quieter experience (we'll assume a check here, given that the new 1.5-liter four-cylinder – the first North American application of this new engine family – should offer more power with less noise than the previous 1.4-liter, four-cylinder powerplant). Other customer-driven changes in the new Volt include a different place to store the charging cable (in the side of the trunk instead of under the load floor) and a new brake system with improved blended regenerative braking feel as well as driver-selectable regen levels. The requested 50-mile range comes from a new, lighter battery that has increased capacity from fewer cells (192 vs. 288) and a simplified control architecture. Along with the new battery, the electric drive unit is a two-motor deal that is up to 12 percent more efficient and 100 pounds lighter, while also being "tremendously smaller," notes Fletcher. It offers 294 pound-feet of torque and a maximum 149 horsepower of "motoring power" delivered to the wheels. GM says it has worked hard to reduced the amount of rare earth materials in these motors, and one of them doesn't use any at all. The new powertrain offers improved acceleration times, as well. The 2016 Volt can go from 0 to 60 miles per hour in 8.4 seconds, a seven-percent improvement, while the 0-30 mph time has been improved by 19 percent, down to 2.6 seconds. The new Volt is more conventional looking, but certainly not completely ordinary.
