Cadillac CT6 to be lighter than CTS, get PHEV model

Cadillac is suddenly one of the most talked about automakers in the US with Johan de Nysschen taking control. The brand claims that it eventually wants to become, once again, the standard of the world. One of the first vehicles to actually prove whether that's possible is its upcoming CT6 flagship sedan. We still don't know what the production version looks like undisguised, but other important details are falling into place. The latest big news sheds some light on the Caddy's powertrain and some estimates of its weight and size.
General Motors product chief Mark Reuss dropped the details at the automaker's Global Business Conference. According to The Detroit News, he revealed that the CT6 would use a twin-turbocharged, 3.0-liter six-cylinder engine with an eight-speed automatic transmission, and a plug-in hybrid would be an additional option. He reportedly claimed it would be the most "powerful six-cylinder gas engine in the segment" and said the hybrid could get around 70 miles per gallon.
Reuss also revealed that the CT6 would be about 53 pounds lighter than the current CTS, despite being about 8 inches longer, according to The Detroit News. If that's the case, the new flagship is about 203.5-inches long, which is 1.5-inches more than the XTS.

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.

Best sport sedans for 2022 and 2023

SUVs dominate the car industry at every size and price level, but some people still prefer the looks, and more importantly, the performance and comfort, of the traditional sedan. With a lower ride height, lighter weight and generally smaller size, they often are much more fun to drive, and can even be more comfortable. Sport sedans of course lean harder on the performance side of things, and are among the best options for sheer speed and fun, thanks to those inherent characteristics. We've rounded up the ones in the segment that do the sporty dance better than any others in 2024 to give you a handy guide when you're shopping for one of your own. You'll find a wide array of cars here including gas, electric and hybrid powertrains. They'll have manual and automatic transmissions and drive the front, rear or all four wheels. Technically a few hatchbacks have slipped in, but they're close enough in look and feel that we wanted to include them. And excluding them means you might miss out on some of the best-driving options available. You wouldn't want that, would you? Alfa Romeo Giulia Why it stands out: Punchy four-cylinder; astounding power from Quadrifoglio; light and nimble character; awesome shift paddlesCould be better: Clunky infotainment; sub-par switchgear Read our Alfa Romeo Giulia review We start this list with one of the most predictable inclusions: the Alfa Romeo Giulia. Yes, it's a stereotype that the Italian sport sedan is fun to drive, but the fact is, well, it is. The Giulia comes standard with a turbocharged 2.0-liter four-cylinder making 280 horsepower, making it one of the most powerful four-cylinders in the segment. It's paired with a snappy and smooth eight-speed transmission and either rear-wheel or all-wheel drive.  The engine is lively and torquey, if a little short of revs, and the chassis feels super-light. The steering is eager and the car jumps into corners. We also highly recommend getting a version with the enormous and superb aluminum paddle shifters that make clicking through gears much more entertaining. And on the topic of the interior, it's attractive, but the various switches and knobs feels a little cheap, and the infotainment system is clunky. Of course there's also the incredible Giulia Quadrifoglio at the high end. It gets a Ferrari-derived twin-turbo 2.9-liter V6 making 505 hp, and it's rear-wheel drive only.
