Carpool Deville aims to be the world's fastest hot tub

The world needs crazy inventors with wild dreams. While we might not long for the things that they create, their contraptions certainly make the day a little more enjoyable. Take the Carpool Deville as an example. Nobody (well, almost nobody) is asking for a hot tub fashioned from a 1969 Cadillac that is still drivable. But now that you know that such a beast exists, don't try to tell us you aren't at least intrigued.
The team behind the six-year-long project has a pretty ingenious setup worked out. The Caddy's original 472-cubic-inch (7.7-liter) V8 both provides propulsion and heats the water. The interior is entirely replaced with a watertight, fiberglass tub that includes working jets, and the controls are all done by hand.
As if just building a mobile hot tub isn't enough, the team behind the Carpool Deville plans to take it racing too. Specifically, they intend to go to the Bonneville Salt Flats later this year to make a top speed run while immersed in water at over 100 degrees. They even have a roll cage all set to install to meet the safety requirements there.

Cadillac puts on a big performance for the Oscars with 'Rise' campaign

Cadillac skipped the Super Bowl, saving its big play for the 91st Oscars telecast tonight. America's luxury brand has a presence planned for nearly every medium, from television to Twitter to stairstep stories tied into the new commercial campaign. Speaking of which, that campaign is called "Rise," and lauds the "now-complete SUV portfolio" as well as Cadillac's determination to get back to the top. Four new spots will debut: "Rise Above," celebrating the XT6 and the rest of the new range, "Take the Stage," focused on the Escalade, "Make Your Escape," all about the XT4, "Take Flight," for the XT5. The first commercial will be 60 seconds, while the other three are 30-second spots. Cadillac chose Childish Gambino's song "Me and Your Mama" for the campaign soundtrack — it works a lot better than you might guess based on the track name. Beyond that, the Cadillac logo will grace the red carpet, the first time any commercial logo has made a home on the walk of honor. The stairs will be decorated with blue horizontals, inspired by the stair-like pattern of blue in the Cadillac crest. The blue in the carmaker's logo is said to represent "knightly valor" — which, yes, is totally made up, but Cadillac made it up a long time ago, not for this campaign. The real point is that two celebrities in attendance will stand on the steps and present their own stories of rising up. You can check out all the commercials here, watch them unveiled in real time during the Oscars telecast, keep up with what your eleventy hundred Twitter friends think by checking out the hashtag #KeepRising, and finish it off with some time on the Keep Rising microsite.

Mary Barra thinks GM is a leader in autonomous tech

Saying General Motors is "among the leaders" in autonomous vehicle technology, CEO Mary Barra rapped about her company's driverless work in an interview with USA Today. Barra covered a number of topics, including well-known efforts, like Cadillac's upcoming Super Cruise technology, as well as hinting at "a lot of efforts that are confidential." "Things are moving quickly in autonomous [cars] because there's so many different pathways and the standards aren't even set. A lot of people can claim leads because people are making advancements in different areas," Barra said. "Next year we're going to have Super Cruise on one of our Cadillacs. On highways you'll be able to take your hands off the wheel and feet off the pedals – with a very creative way to make sure the driver is alert and involved in the driving process." As for those "confidential" efforts, feel free to speculate. GM has recently confirmed that it'd be running autonomous Volts at its Warren, MI tech center, which certainly indicates that the company is playing with much more than Super Cruise. GM will need to continue to embrace autonomous driving, owing to both traditional competitors like Toyota, as well as non-traditional opposition, like Google and Apple. Speaking of its competition from Silicon Valley, Barra was asked about two of the region's biggest names – Apple's Tim Cook and Tesla boss Elon Musk. "I have tremendous respect for Tim Cook, and I don't really think he needs advice from me," Barra told USA Today with a laugh. And when asked about Apple's future as a "viable competitor," she said, "I have no insights other than what I read in the papers. But it would be foolish for me not to assume that they're going to." As for Mr. Musk's openness about future products and how it contrasts with GM's relatively closed attitude, Barra also gave a chuckle. "I'm sure you would like me to say yes. I think we're fundamentally different. Look at our volume and look at the segments where we compete. His product line – his two products – his scale, it's completely different." The rest of Barra's interview is certainly worth a read, and includes talk about the Volkswagen diesel scandal, GM's changed relationship with the National Highway Traffic Safety Administration, and Uber.
