Autonomous tech will drive motorheads off the road

While autonomous technology could make car travel much safer and more efficient — and automakers and marketers are salivating over the prospect of a "passenger economy" that could potentially generate $7 trillion by 2050 — those of us who enjoy driving are not so stoked. Experts have predicted that as autonomous vehicles are deployed in large numbers, human-driven cars eventually could be outlawed on public roads due to the carnage they create, which is currently more than 41,000 deaths a year in the U.S. alone and climbing. Such scenarios have driving enthusiasts envisioning a "Red Barchetta" style nightmare becoming reality, making Rush lyricist Neil Peart a clairvoyant as well as one of rock's most badass skin-pounders. But there could be a couple of refuges left for motorheads, and they won't be on public roads. As Popular Science's Joe Brown points out in a recent editorial, we're seeing a wave of vehicles being offered by legit mainstream automakers that aren't made for public roads. The poster child of this vanguard is the 2018 Dodge Challenger SRT Demon, which comes with a crate full of goodies that lets you turn the already formidable street-legal muscle car into a drag-strip dominator. Brown also notes that two out of five of the Ford GT's driving modes are for use on the track, "catering to the $450,000 machine's club-racing clientele." We're also currently enjoying the heyday of production off-road-ready pickups that kicked off with the Ford Raptor in 2009. The latest salvo in this escalating war of overachieving trucks is the Chevy Colorado ZR2 that can take on the likes of California's Rubicon Trail without issue. Brown also gives a shout-out to his magazine's Grand Award Winner, the Alta Motors Redshift MX, which "isn't even allowed on public roads" and is "meant for bombing around motocross tracks, big backyards and single-track woods trails." If you follow Brown on Instagram, you know that he's also a two-wheel aficionado, and he points out that sales of off-road bikes are leaving street machines in the dust. Sales of off-highway motorcycles rose 29 percent between 2012 and 2016, according to the ­Motorcycle Industry Council — compared to 6 percent for road-bike sales during the same period. "That's a nearly 400-percent drubbing," Brown remarks.

2021 Chevy Tahoe, GMC Yukon fuel economy and towing capacities go official

Most of the puzzle pieces have fallen into place with GM’s new full-size SUVs, but today we have fuel economy and towing to add to the picture. Numbers for the standard 5.3-liter V8 and upgrade 6.2-liter V8 are out, but GM has held back on the 3.0-liter turbodiesel inline-six for the time being. Those numbers are most likely not ready yet. Minor improvements and decreases are seen throughout the Tahoe/Suburban and Yukon/Yukon XL lineup. Because there are so many variants, weÂ’re going to just lay them out below for you. 5.3-liter V8 2021 Tahoe/Yukon 2WD: 16/20/18 2021 Tahoe/Yukon 4WD: 16/20/18 2021 Suburban/Yukon XL 2WD: 16/20/18 2021 Suburban/Yukon XL 4WD: 15/19/17 6.2-liter V8 2021 Tahoe/Yukon 2WD: 15/20/17 2021 Tahoe/Yukon 4WD: 14/19/16 2021 Suburban/Yukon XL 2WD: 15/20/17 2021 Suburban/Yukon XL 4WD: 14/19/16 As you can see, there isnÂ’t a whole lot of difference between two-wheel drive and four-wheel drive options. You can eke out an extra mpg here and there, but itÂ’s a penalty weÂ’d be happy to live with to have four-wheel traction. The biggest loser in all of this is highway mpg. Chevy has made the trucks bigger and added weight with the independent rear suspension, causing a decrease in fuel economy. For example, a 2020 Tahoe with the 6.2-liter V8 and four-wheel drive is rated at 14/22/17. The 2021 truck drops 3 mpg on the highway and 1 mpg in the combined rating. There are improvements to be found, though. A 2020 Suburban with the 5.3-liter V8 and four-wheel drive is rated 14/21/16. Fuel economy in the city goes up 1 mpg, but you lose 2 mpg on the highway and 1 mpg in the combined rating. ThereÂ’s a bit of give and take here, but at least a slight increase in city mpg has accompanied the greater loss in highway fuel economy. 2021-chevy-tahoe-chicago-01 View 12 Photos As for towing, the Tahoe/Yukon with the 5.3-liter V8 and two-wheel drive has a new 7,900-pound capacity, and the four-wheel drive model is rated at 7,700 pounds. Respectively, those are the best figures youÂ’ll get with the standard towing capacity. Opt for the maximum towing package, and the Tahoe/Yukon capacities go up to 8,400 pounds (two-wheel drive) and 8,200 pounds (four-wheel drive). The numbers all take slight cuts when you go for the 6.2-liter V8. Both the Suburban and Yukon XL offer similar or identical towing figures as their shorter counterparts do.

Can DARPA hack into a Chevy Impala through OnStar?

An ex-video game wizard named Dan Kaufman tracked a circuitous route to becoming the head of the Software Innovation Division at the Defense Advanced Research Projects Agency. DARPA normally makes these pages because of its work with autonomous vehicles and automobile technology that overlaps with military applications, but for the past five years Kaufman and his multiple research teams have been working on creating unhackable software code that could be used in military drones. Part of that work has involved hacking into just about everything else, and as a segment on 60 Minutes reveals, that includes cars. The masterminds discovered a way to hack into OnStar, the General Motors telematics system. After figuring out how to hook into OnStar's emergency communication system, they overwhelmed it with data. While the computer was busy trying to manage the overrun of data, the research team inserted code that took control of the sedan's other computers, giving it control. So while reporter Leslie Stahl tooled around in a parking lot, a DARPA researcher with a laptop would occasionally take control of the car, like by applying its brakes or, conversely, removing the ability for Stahl to use the brakes. Hacking into vehicles has been in the news for years: Car and Driver ran a feature on the various ways cars could be hacked in 2011, two hackers released a car-hacking code at the hacker-fest Defcon in 2013 and demonstrated how it worked on a Toyota Prius and Ford Escape, and German researchers demonstrated how they could hack into BMW's Connected Drive remote-services system last week via an attack on the cars' telematics units. This isn't about GM or Onstar or the future; hacking into cars of all kinds isn't coming, it's here, and it doesn't take the half-billion-dollar annual budget of a small DARPA division to do it. Check out the 60 Minutes video on the CBS site (you can watch the entire video from a mobile device without logging in). The OnStar hacking starts at 6:45, but it's worth watching what leads up to that. News Source: Jalopnik Chevrolet Safety Technology Infotainment Autonomous Vehicles Videos Sedan hacking 60 minutes
