First 2015 Chevy Corvette Z06s en route to owners [w/video]

Pretty much right on schedule, Chevrolet has begun shipping the very first customer examples of its 650-horsepower, supercharged Corvette Z06. In fact, according to General Motors, the earliest Z06s could be in customer hands by the end of this week. "It has been an incredible opportunity to work on Chevy's most capable model," said Jeff Lamarche, manager of Chevy's Bowling Green Assembly plant. "It truly is an amazing car, and we're thrilled to get them into the hands of our eager customers." Prices for the Z06 start at $78,995 for the hardtop model, while the first-ever Z06 Convertible kicks off at $83,995. Take a look below for the official press release from Chevrolet, and while you're down there, we've slipped in a new video of Corvette Racing's Tommy Milner taking a hot lap of Road Atlanta in a Z06, complete with some Performance Data Recorder footage. First 2015 Corvette Z06s on Their Way to Customers Most capable model in Chevrolet's history now shipping from Bowling Green BOWLING GREEN, Ky. – Chevrolet is now shipping the all-new 2015 Corvette Z06 coupe from Bowling Green Assembly and some early customers could receive the much-anticipated supercar later this week. "It has been an incredible opportunity to work on Chevy's most capable model," said Jeff Lamarche, plant manager of General Motors' Bowling Green Assembly plant, "It truly is an amazing car, and we're thrilled to get them into the hands of our eager customers." The new Corvette Z06 offers the most choice for customers in the model's history. It is the first Z06 to offer an available eight-speed paddle-shift automatic transmission and, thanks to a stronger aluminum frame, a removable roof panel. In addition, it is the first time since 1963 that the Z06 is available as a convertible – which will arrive in early 2015. The new LT4 supercharged 6.2L V-8 engine is SAE-certified at 650 horsepower (485 kW) at 6,400 rpm and 650 lb-ft of torque (881 Nm) at 3,600 rpm – making the 2015 Corvette Z06 the most powerful production car ever from General Motors and one of the most powerful production cars available in the United States. To balance performance and efficiency, the LT4 leverages a trio of advanced technologies – direct injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing –with a new, more efficient supercharger. The LT4 helps make the Corvette Z06 the most capable car in the brand's history.

China's rise, global restructuring wither GM's Korea division

An article in the Daily Kanban suggests the sun is setting on GM Korea, and it could already be well into dusk. GM Korea came about when General Motors, along with co-investors SAIC and Suzuki, bought Daewoo Motors from parent company Daewoo Group in 2001; it had a previous tie-up with GM, a joint venture that ended in 1992, although Daewoo cars were based on GM cars until 1996. Over the decade following the purchase, it became such an important part of operations that it was renamed GM Korea in 2011, "to reflect its heightened status in [the] global operations of GM." Just two years later, the printed rumors were that the subsidiary responsible for a fifth of Chevrolet's global production could be shutting down. The division's sales were down almost 21 percent through November of last year, counting domestic South Korean sales, exports, and CKD – Complete Knock Down – products. That makes the labor strife, already an issue for four years, even more acute, reports say the subsidiary will lose $36 million a year if it can't get the job and wage cuts it wants, and government concessions can't make up for the losses. And it gets worse, so head over to Daily Kanban to read the rest of the story.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
