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.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.

Want a V8 on the cheap? Buy a work truck

In case you didn't notice, V8 cars have gotten pretty expensive. If you want a modern muscle car like the Dodge Challenger R/T, Ford Mustang GT, or Chevy Camaro SS, you'll need between $34,000 and $38,000 for a stripped out example of one. The cheapest of those is the Challenger, and the priciest is the Camaro. These are also the cheapest V8 cars the companies offer. But if you absolutely have to have a V8 for less, there is an option, work trucks. As it turns out, all of the Big Three offer their most basic work trucks with V8s. And because they're so basic, they're pretty affordable, especially when sticking with the standard two-wheel drive. A Ram 1500 Tradesman with a V8 can be had for as little as $29,840, which is a little more than $4,000 less than a Challenger R/T. For a bit more at $30,275, you can have a Chevy Silverado W/T, almost $8,000 less than a Camaro SS. The most expensive is the V8 Ford F-150 starts at a starting price of $30,670, which is a bit over $5,000 less than the Mustang. Of course you'll be in an ultra bare bones vehicle with few comforts, and the price will go up if you add stuff, but we're bargain hunting here, and sacrifices are sometimes necessary. Besides, what you lose in comfort, you gain in loads of cargo space and towing (try to look at the bright side). Also, as a side note, all three trucks are available with optional electronic locking rear differentials. At the discounted price of these trucks, you still get a heaping helping of power. The most potent of the trio is the Ram 1500 Tradesman with 395 horsepower and 410 pound-feet of torque generated by a 5.7-liter V8. Compared with the Challenger R/T, the Ram is up by 20 horsepower and they're tied for torque. The value proposition is even more stark between the two vehicles when looking at the price per horsepower. Each pony in the Ram costs $75.54, while the Challenger charges you $90.91. The Challenger is also more expensive per horsepower than its close competitors. The F-150's 5.0-liter V8 is just barely behind the Ram with 395 horsepower and 400 pound-feet of torque. That's still more power than the Challenger, and it matches the torque of the 2017 Mustang GT. On the down side, it still would be down 20 horsepower on that same 2017 Mustang, and it's behind by 60 horsepower and 20 pound-feet on the new 2018 Mustang GT. The F-150 also just edges out the Mustang in the dollar per horsepower measure.
