2015 Chevy Tahoe gets Police Patrol Vehicle treatment

That was fast. Mere days after showing a Police Concept based on the 2015 Tahoe at the SEMA Show, Chevrolet has announced that it will build a PPV model based on the SUV to do battle with the Ford Police Interceptor Utility (Explorer) and Dodge Durango Special Service.
You'll recall that the Tahoe has been police staple for several years, predating both the Explorer and Durango police variants, so the fact that the new model would spawn a police variant is hardly surprising. Like the civilian model, the 2015 PPV benefits from a more efficient 5.3-liter, direct-injection V8 that pumps out 355 horsepower and 383 pound-feet of torque. It also features more high-strength steel, offering better crash protection, on top of optional safety items like lane departure warning, forward collision alert and a Safety Alert Seat.
The press release is rather light on police-specific items, aside from the auxiliary battery, which keeps the myriad of electronics in a modern police car running even when the engine isn't. Lightbars, 17-inch steel wheels on Goodyear Eagle RS-A tires and a push bar round out the mods for the Tahoe PPV. The cabin features a revised center console and room for laptop and other equipment mounts.

Zombie cars: Discontinued vehicles that aren't dead yet

Car models come and go, but as revealed by monthly sales data, once a car is discontinued, it doesn't just disappear instantly. And in the case of some models, vanishing into obscurity can be a slow, tedious process. That's the case with the 12 cars we have here. All of them have been discontinued, but car companies keep racking up "new" sales with them. There are actually more discontinued cars that are still registering new sales than what we decided to include here. We kept this list to the oldest or otherwise most interesting vehicles still being sold as new, including a supercar. We'll run the list in alphabetical order, starting with *drumroll* ... BMW 6 Series: 55 total sales BMW quietly removed the 6 Series from the U.S. market during the 2019 model year. It had been available in three configurations, a hardtop coupe, a convertible and a sleek four-door coupe-like shape.   BMW i8: 18 total sales We've always had a soft spot for the BMW i8, despite the fact that it never quite fit into a particular category. It was sporty, but nowhere near as fast as similarly-priced competitors. It looked very high-tech and boasted a unique carbon fiber chassis design and a plug-in hybrid powertrain, but wasn't really designed for maximum efficiency or maximum performance. Still, the in-betweener was very cool to look at and drive, and 18 buyers took one home over the course of 2021.   Chevy Impala: 750 total sales The Impala represented classic American tastes at a time when American tastes were shifting away from soft-riding sedans with big interior room and trunk space and into higher-riding crossovers. A total of 750 sales were inked last year.   Chrysler 200: 15 total sales The Chrysler 200 was actually a pretty nice sedan, with good looks and decent driving dynamics let down by a lack of roominess, particularly in the back seat. Of course, as we said regarding the Chevy Impala, the number of Americans in the market for sedans is rapidly winding down, and other automakers are following Chrysler's footsteps in canceling their slow-selling four-doors. Even if Chrysler never really found its footing in the ultra-competitive midsize sedan segment, apparently dealerships have a few leftover 2017 200s floating around. And for some reason, 15 buyers decided to sign the dotted line to take one of these aging sedans home last year.

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.
