Why the Corvette's Performance Data Recorder can be illegal in some states

The Performance Data Recorder with Valet Mode available on the 2015 Chevrolet Corvette Stingray seems like a fantastic tool for many owners. Whether they are taking 720p video while lapping the track in their new 'Vette, or just want to protect their purchase from inconsiderate joyriders, the system offers a lot of functionality in one package. However, one of the PDR's features might get buyers in trouble with the law, and it has nothing to do with recording some illicit high-speed driving on a favorite back road. The problem hinges on the various state laws concerning a person's right to privacy.
According to a letter posted by Jalopnik, Chevy dealers are asking 2015 Corvette owners not to use the Valet Mode portion of the PDR because it records audio in the cabin, in addition to performance specs. That's a problem because privacy laws vary from state to state with some requiring just one side's consent to tape sound and others requiring all parties to agree. According Jalopnik, 15 states mandate everyone's permission beforehand, but it's not clear whether these numbers are up to date. (Actually, the report varies, saying 13 states in some places and 15 in a list.)
According to the letter, Chevy is already working on a software update for the near future to rectify the issue. It's possible that simply adding a warning to drivers and the ability to turn off the audio recording function in Valet Mode might solve the problem. Obviously, this doesn't preclude Corvette drivers from using the performance aspect of the PDR, and owners are free tape lap after lap at the track.

Bentley Continental GT V8 and Toyota 4Runner | Autoblog Podcast #604

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Consumer Editor Jeremy Korzeniewski and Senior Editor, Green, John Beltz Snyder. First, they talk about driving the 2020 Bentley Continental GT V8 First Edition, followed by the 2020 Toyota 4Runner TRD Off-Road. Then they revive a format called "This or That," discussing the Jeep Wrangler vs. Gladiator, Subaru Forester vs. Outback, Mustang vs. Camaro vs. Challenger, and whether they'd rather spend $25,000 on a new or vintage car. They've got an update on a previous Spend My Money segment, and, finally, they help another listener pick a daily driver.

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.
