MIT puts V2V technology on its 2015 Top Ten list

Of all the technologies swimming around the automotive world, it is vehicle-to-vehicle communication that the Massachusetts Institute of Technology has fished out as one of its Ten Breakthrough Technologies of 2015. It joined emerging tech like brain organoids, supercharged photosynthesis, and Project Loon on the list, and got the nod over autonomous driving because, as the MIT Technology Review wrote, V2V communication "is likely to have a far bigger and more immediate effect on road safety." How so? Because actual cars transmitting data like their location, speed, steering angle, and state of braking to one another at least ten times per second provides a greater degree of awareness than sensor readings and algorithms. The US Department of Transportation and the National Highway Traffic Safety Administration have been working for years on standards and a regulatory schedule for introducing V2V to the marketplace, and Cadillac plans to incorporate V2V into at least one of its vehicles by 2017. Since we've begun the year with a number of stories of cars being hacked into, that got us wondering about the security of V2V communications. In a recent piece by our own Pete Bigelow on what motorists should know about getting their cars hacked into, he wrote that although cyber break-ins are extremely difficult, expensive, and time-consuming to do remotely, V2V is "one more conceivable avenue a hacker could use to impact multiple cars at a given time." So we spoke to Wilmington, Massachusetts-based Security Innovation about it. The automotive consultancy company has been working with the DOT since 2003 on V2V technology and the issues around it - namely security and privacy - and its chief scientist, William Whyte, is the technical editor of the Institute of Electrical and Electronics Engineers (IEEE) 1609.2 standard outlining its security protocols. Those protocols are expected to be finalized by the DOT toward the end of this year and then come into effect in 2016, and the company's Aerolink product is the security solution Cadillac will use. Whyte said, "If you hack into a car, V2V is the hardest place to start," and Pete Samson, the general manager of Security Innovation's automotive team, said "There are ten or 12 alternate attack surfaces" around the car that would make much easier targets.

2016 Hennessey CTS-V is properly ridiculous with 1,000 horsepower

We truly live in a halcyon era of automotive performance with models like the latest Shelby GT350 Mustang and 707-horsepower Challenger Hellcat. And now Hennessey Performance Engineering is bringing something with absolutely obscene power to the world with its tuned 2016 Cadillac CTS-V that packs a ludicrous 1,000 horsepower. The latest CTS-V isn't even on sale yet but should be a powerhouse straight from the factory. Under its carbon fiber hood is a 6.2-liter supercharged LT4 V8 with 640 horsepower and 630 pound-feet of torque that makes the sedan capable of a 200-mile-per-hour top speed. Hennessey's take ditches the blower in favor of two turbos to feed air to the engine. To cope with the extra power, the mill gets upgrades like forged aluminum pistons and forged steel parts for the rods and crankshaft, and transmission upgrades are also necessary to make it all work. Buyers can even spec things like carbon-ceramic brakes and a widebody kit to allow for bigger tires. The crazy numbers are leading to some big performance claims from company founder John Hennessey. "I believe that our 2016 Twin Turbo CTS-V will have a top speed approaching 240 mph," he said in the Caddy's announcement. Hennessey is building just 24 of these 1,000-horsepower sedans for the 2016 model year. However, for those that want to keep the supercharger under the hood, the company is also offering upgrades with 750 hp and 800 hp for the CTS-V too. All of them sound absolutely ridiculous in an utterly fantastic way. 2016 HPE1000 Twin Turbo Cadillac CTS-V Texas Tuner Plans to Build World's Fastest 4-Door Sedan Sealy, Texas-When the next generation Cadillac CTS-V hits the streets later this year, it will have 640+ hp and a top speed of nearly 200 mph. To the team at Hennessey Performance Engineering (HPE), this is a good starting point. The company plans to pick-up where they left off with the last gen CTS-V by producing the world's fastest 4-door sedan: The Hennessey HPE1000 Twin Turbo CTS-V. "A couple of years ago, the State of Texas gave us the opportunity to test one of our specially tuned CTS-Vs – our VR1200 Twin Turbo coupe. It ran 221 mph (356 km/h) on State Highway 130, near the Circuit of the Americas", said company founder, John Hennessey. "It was still pulling on when we ran out of road. I believe that our 2016 Twin Turbo CTS-V will have a top speed approaching 240 mph (386 km/h)". Hennessey plans to offer a limited run of only 24 units for the 2016 model year.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid
