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!"

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.

Burt Reynolds' movie re-creations fetch $379,500 in Vegas

The recent death of Hollywood legend and automotive enthusiast Burt Reynolds helped drive up the value of four of his former cars from the 1970s and '80s, which sold last weekend at Barrett-Jackson's Las Vegas auction for a combined $379,500. Reynolds, who died Sept. 6 at age 82, had offered three Pontiac Trans Ams — two of them re-creations of the cars he drove in "Smokey and the Bandit" and "Hooper" and the third from 1984 used to promote his United States Football League team, the Tampa Bay Bandits. The fourth was a 1978 Chevrolet R30 pickup truck, styled like the one featured in "Cannonball Run." The "Bandit" re-creation, a 1978 Pontiac Firebird Trans Am that Reynolds ordered to be as "movie-correct" as possible but featuring a custom-built 200-4R automatic transmission, sold for $192,500. The car features a freshly built Pontiac 400 cubic-inch V8 mated to a four-speed automatic and featuring all-new Butler Performance parts and air-conditioning components. Reynolds reportedly said this was his favorite car from his films, and it even came with an authentic movie-correct CB radio and CB antenna. The red retro-rocket "Hooper" '78 Firebird, with a 403 cubic-inch V8 and a three-speed automatic, hammered for $88,000. By comparison, a gold 1978 Trans Am also offered at the Las Vegas auction but not connected to Reynolds fetched $27,500. The 1987 Chevy R30 pickup was a re-creation of the Indy Hauler pace truck seen jumping over a moving freight train in "Cannonball Run." It hammered for $49,500. The fourth car never appeared in any of Reynolds' films but is instead the only surviving example of two Trans Ams used to promote the Tampa Bay Bandits of the now-defunct USFL, having been driven out onto the field by Reynolds and his late friend and co-star, Jerry Reed, during opening day one season. It also sold for $49,500. At the Barrett-Jackson Scottsdale Auction in 2016, Reynolds accompanied a 1977 Trans Am used to promote "Bandit" onto the auction block. That car sold for $550,000.
