Chevy Corvette is latest car breached by hackers

UPDATE: This story has been updated with comment from General Motors. In the latest car-hacking exploit in a summer full of them, researchers from the University of California-San Diego say they've found a way to manipulate braking in a 2013 Chevrolet Corvette. The vulnerabilities may not be limited to that model. Cyber-security researchers breached the car's security systems via a device they had plugged into the Corvette's OBD-II port, and through that connection, they sent messages that could turn windshield wipers on and off and tamper with the brakes as the car drove at low speeds. It's the latest in a series of car hacks that involve access to critical systems obtained via the OBD-II port, where drivers can plug in devices that provide anything from diagnostic information for mechanics to driving information for insurance companies. Last November, cyber-security engineers from Argus Cyber Security remotely controlled vehicle functions in a car that had a OBD-II dongle called a Zubie installed. In January, researchers from Digital Bond Labs found security holes in an information-tracking dongle popular with more than 2 million Progressive Insurance customers. Those came before prominent hacks unveiled in recent weeks, in which researchers remotely commandeered control of a Jeep Cherokee and, separately, showcased problems with GM's OnStar infotainment system. Regarding the dongles that plug into the OBD-II ports, Stefan Savage, a Cal-San Diego professor involved in the research, tells WIRED that, "we acquired some of these things, reverse-engineered them, and along the way, found that they had a whole bunch of security deficiencies." Savage and others unveiled the latest study at the Usenix security conference Tuesday. In a video of their exploit entitled "Fast and Vulnerable," they show how they sent SMS messages from a smartphone to the dongle plugged into the car's OBD-II port. From there, their messages accessed the CAN bus, a network on the car that connects individual electronic control units, which control dozens of vehicle functions. As they send the commands to brake the car, the driver of the Corvette notes "the pedal doesn't react to any pressure." General Motors issued a written response Wednesday, warning drivers to be careful with third-party devices they plug into their OBD-II ports.

Best new convertibles for 2024 and 2025

If you’re here, then youÂ’re already in the right mindset. Convertibles rule, and we have all the best convertibles listed for you further below. Driving around with the top off is an experience you need to live to fall in love with. When the weatherÂ’s right, youÂ’re on a proper bit of road, and the car youÂ’re in is a good one, few automotive experiences can top it. The experience is extra special when you have a musical exhaust note filtering directly into your ears and echoing off the landscape around you. And while rolling the windows down and opening a moonroof can get you part of the way there, it's nothing like feeling the wind wash over you with absolutely no roof overhead. The downsides can be just as harsh as the upsides when youÂ’re in the wrong conditions, though. Convertibles are typically worse to live with in cold climates, and driving around with the top up frequently means you might be subject to more road noise and worse visibility than an equivalent coupe. And when it comes to pure performance, convertibles are inherently compromised from a weight and structural rigidity perspective. All that said, we still think the upsides outweigh the compromises if your number one objective is to simply have fun. ItÂ’s a good thing then that there are a ton of great convertibles for sale these days. And no, the list of possibilities isnÂ’t as long as it used to be. Long-running standbys like the Mercedes-Benz E-Class and C-Class Convertibles are gone (replaced by the one CLE-Class). And so are others like the Audi TT Roadster, Fiat 124 Spider and Nissan Z Roadster. Nevertheless, opportunities abound from the ultra-cheap and fun, to physics-defying supercars and everything else in between. WeÂ’ll give you options for which new convertibles we think are the best below, so read on to find out.   Mazda MX-5 Miata Pros: Lightweight and compact; great engine and transmission combo; one of the most raw and pure driving experiences out thereCons: Not great for tall people; infotainment is dated; tiny trunk Read our Mazda MX-5 Miata Review Miata is always the answer, right? In this case, that rings even more true than usual. In fact, you could stop reading this list right here and go buy a Miata and youÂ’d likely be just as happy driving it around as you would be in any of the more expensive offerings that follow. ThatÂ’s just the magic of the MX-5.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
