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.

Cadillac will build a Tesla fighter, sources say, as GM's leading EV brand

WASHINGTON — Cadillac is expected to become General Motors' lead electric vehicle brand as the largest U.S. automaker gears up to introduce a new model under that luxury marquee to challenge Tesla, two people briefed on the matter said Thursday. GM is set to announce Friday as part of an investor update that a Cadillac will be the first vehicle based on its forthcoming "BEV3" platform, the people said. The vehicle platform is the basis for vehicle underpinnings, including the battery system and other structural and mechanical parts. GM is not expected to disclose on Friday additional details, including precisely when the Cadillac EV will be built, whether it will be a crossover or sedan, or where it will be assembled, the sources said. A GM spokesman declined to comment. GM had previously focused on making electric vehicles under its mass market Chevrolet brand, including its plug-in Chevrolet Volt and battery electric Bolt. GM announced last year it was ending production of the plug-in Volt as well as a low-selling plug-in Cadillac CT6, even as it moved to boost EV spending. GM said in November as part of its restructuring efforts it was doubling resources for electric and autonomous vehicle programs over the next two years. Last month, two Ohio senators asked GM to commit to building all future electric vehicles for U.S. buyers within the country. GM said in 2017 it planned by 2021 to introduce a new dedicated flexible electric vehicle architecture and an advanced battery system to support the development of at least 20 new models in the United States and China. GM said in 2017 that a new electric vehicle platform in 2021 will serve as a base for at least nine derivatives, ranging from a compact crossover to a large seven-passenger luxury sports utility vehicle and a large commercial van. Johan de Nysschen, who was then Cadillac's president, told Reuters at the Detroit Auto Show in January 2018 the luxury brand will play a "central role" in GM's electrification strategy, including China. He added that Cadillac would be "at the forefront" of rolling out new electric vehicles in the United States and China. He left GM in April. This week, GM said Cadillac sales in China rose 17.2 percent in 2018, surpassing 200,000 units for the first time. GM Chief Executive Mary Barra has said that GM aims to sell 1 million electric vehicles a year by 2026, many of them in China, which has set strict production quotas on such vehicles.

Comparing Cadillac's crazy classy coupes

I just returned from the press launch of Cadillac's new ATS-V, a high-performance version of the US luxury marque's entry-level compact car. While ordinary ATVs offer a choice of a 202-horspower, 4-cylinder, a 272-hp turbocharged four or a 321-hp V-6, this one packs a twin-turbo V-6 that pumps out 464 thoroughbred horses and 445 pound-feet of hard-charging torque. Starting at $62,000 for the sedan and $64,000 for the sexy coupe, ATS-Vs are available with a 6-speed manual (with Active Rev Matching and no-lift shift capability) or an 8-speed automatic with steering-wheel shift paddles. They comes with GM's latest 4-mode Magnetic Ride Control, 5-mode Performance Traction Management (with launch control), competition-spec traction and stability controls, an electronic limited-slip differential, specially-tuned electric power steering, huge Brembo brakes, and added air cooling for their engine, transmission, and rear axle lubricants. They roll on 18-inch Michelin Pilot Super Sport tri-compound summer tires on 9-inch-wide front alloy wheels and 9.5-inch-wide rears. And they will rocket from rest to 60 miles per hour in less than four seconds while delivering 16 city EPA miles per gallon and 24 highway with the automatic and 17/23 with the manual transmission. The obvious purpose of all this technology is to effectively endow Cadillac's latest V-Series models with a rarely achieved true dual personality: go, stop, and corner like race cars on a track, then sooth, coddle, and entertain like luxury cars on the way to and from the track, or work. We had ample opportunity to verify both personalities with multiple hot laps of the Circuit of the Americas (COTA) Grand Prix course, followed by a more leisurely drive on public roads near Austin, TX. Even lacking wheel-to-wheel comparisons, we believe these hot new ATS-Vs are fully competitive with their pricier German competitors, and probably superior in some ways. So now, Cadillac will offer not one but two very sharp-looking, upscale, small-volume, 2016 compact coupes, almost the same size and at similar prices, but with totally different missions: this new high-performance ATS-V and the soon-to-be-upgraded ELR extended-range EV. The key question: why? Aside from its cramped back seat and ridiculous $76,000 starting price, I loved the ELR when it was introduced for 2014.
