Cadillac CT4 and CT5 high-performance V cars spied

This summer, Cadillac teased much more impressive V-series models than the lukewarm CT4-V and CT5-V. Now we get a better look at both super sedans, each one boasting more aggressive, but subtle visual upgrades. Normally we would talk about the visual changes to each car individually, but the changes are nearly identical between the cars. They both get deeper chin spoilers and lower side skirts. The lower grille opening now features slatted sections on either end. The headlights, main grille and hood all look unchanged from the regular V models. The same goes for the rear bumpers and tailpipes. The rear spoilers on both are much taller, though. The wheels on the CT4 look about the same as the CT4-V, but the CT5 wheels look a bit different with more detail. We also get a good look at the wheel-filling brakes. Cadillac hasn't said anything concrete about the specifications of the hotter CT4 and CT5 models, except that they'll definitely be faster than the revealed V models. One thing we do know, thanks to our spy photographer's video from earlier this year (shown above), the CT5 will get a V8. Our bet is on it being the Blackwing twin-turbo V8 that's available in the CT6-V and CT6 Platinum. It would probably have at least the same output at the CT6-V at 550 horsepower and 640 pound-feet of torque. Expect the 10-speed automatic transmission to carry over with it. This drivetrain would also open up the possibility of all-wheel drive. As for the fast CT4, it could potentially revive the ATS-V's twin-turbo V6 with 464 horsepower and 445 pound-feet of torque. It would probably also get a 10-speed automatic and maybe all-wheel drive as an option.

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.

Sunday Drive: Classic American nameplates and one exciting new German

Our look back at last week's biggest automotive stories focuses first on the Jeep Wagoneer, an unequivocal American classic. Not only did the Wagoneer play a pivotal role in kicking off America's current love affair with the sport utility vehicle, it legitimized the Jeep brand in the mind of consumers looking not just for something to ably take them off the beaten path, but to do so in comfort, with the entire family along for the ride. So it comes as little surprise that Jeep decided to take one vintage Wagoneer, modernize it with a 5.7-liter Hemi V8 engine, and put the thing on display as part of its annual Moab Easter Jeep Safari. We're in love. Our next two stories focus on Cadillac. First up is news that the striking Escala Concept is headed for production in 2021 to serve as the brand's flagship luxury sedan. The second story involves Caddy's current top rung, the CT6, which gets a new twin-turbo V8 engine as part of its V-Sport package. And finally, we round out this look at last week's headlines with the 2019 Mercedes-Benz C-Class Coupe and Cabriolet. We're mighty keen to try out Benz's new AMG-fettered turbocharged inline-six engine, and the C Coupe looks like a fine point of entry. As always stay tuned to Autoblog this week for all the latest automotive news.
