Chevy Corvette gets Valet Mode with Performance Data Recorder [w/video]

For the 2015-model-year, Chevrolet introduces Valet Mode for the Corvette, an enhancement to the Performance Data Recorder (PDR) already available and to your peace of mind. The PDR already captures 720p HD video with a windshield-mounted camera, records interior audio with a cabin microphone and gathers telemetry data using GPS, saving the data to an SD card in the glovebox. You can then watch your track-day antics with various information overlays on the center console screen.
Valet Mode will let you hit 'Replay' when your car gets pulled up front smelling vaguely of fricasseed clutch. Turned on by entering a four-digit code, it also locks the interior storage spaces and turns off the infotainment system. It can't be turned off until the code is re-entered. There's a press release below with more information as well as a video that explains how it works, with the obligatory dig at the 'Vette's biggest foe.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.

This is what a 2017 Chevy Camaro Z28 could look like

The latest Camaro Z28, the enthusiast darling of the somewhat frumpy fifth-generation pony car, only hit the scene in 2014. It housed the wonderful 7.0-liter, naturally-aspirated LS7 small block V8 and featured a ton of aero bits. The trickest pieces may have been the dynamic spool valve shocks, legitimately race tech for the road. So with the new Camaro out in the wild, we were wondering what a new Z28 might look like, and thus, commissioned these renders based on our best guesses as to what a future Z28 might be. Since Chevy didn't stray too far from the Zeta-chassis Camaro formula with its new Alpha-based car, our vision of a new 2017 Camaro Z28 likewise is a sequel rather than a reboot. The exterior styling and aero details are similar, but sleeker. The defining and protruding front splitter is back, but it's smoothed slightly and better integrated. It shares quad exhaust pipes with the lowlier SS, but they're of the beveled Z06 variety, and sized up to a howitzer caliber. Instead of a weak faux rear fender vent, our version gains a real brake cooling duct. Some iconic elements, like the hood extractor vent and the large decklid spoiler, remain. What we can't see, we have to speculate on. As the track-focused, hardcore pony car in the Camaro lineup, the Z28 will have to do battle with the Ford Shelby Mustang GT350R. There's simply no avoiding it. And whereas Ford distinguished that car with a 5.2-liter, 526-horsepower, flat-plane-crank V8, Chevy is likely to look to the parts bin to find motivation. This isn't a knock; the LS and LT-series small block V8s are both numerous and power-dense. And there's one engine that seems to do the trick: the LSA, last seen in the old CTS-V and still on sale in the Camaro ZL1 (and of course, still being produced as a crate engine). In ZL1 form, the LSA makes about 580 hp, which is a nice margin over the GT350R. It's also a high-zoot but not top-of-the-line mill, having been mostly superseded by the 650-hp LT4. That puts our probable Z28 far enough behind the new CTS-V and current Corvette Z06 in the pecking order to be a safe bet, without hobbling it with the LT1 shared with the Camaro SS and regular Corvette. Will those trick spool-valve shocks from Multimatic make it to the Z28 again? Ford is taking the GT350R very seriously, and if the expensive but supremely capable suspension system is required to manhandle the Shelby at the track, you can bet that Chevy will pony up for it.
