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.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.

Watch a 2015 Corvette Z06 run the quarter in 11.7 seconds

We're not writing about this because it's an amazing run, we're writing about it because it appears to be the first run. Someone took a 2015 Corvette Z06 to Royal Purple Raceway in Baytown, Texas and blasted it down through the quarter mile. It's still wearing the dealer number in wax pen on the windshield and dealer plates, so this example is fresh from the mold. It's also a seven-speed manual. General Motors said the row-your-own Z06 can do the 'strip in 11.2 seconds, and they undoubtedly had a professional driver and more than one run to set that time. To have Just Some Guy show up at the raceway and do an 11.7 at 120.54 mph on his first run means we expect good things to come as Z06s get delivered to their owners. Check out the run in the video.
