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 CT5 spied with quad exhaust, could signal a hotter version is coming

The 2020 Cadillac CT5 just broke cover at the NY Auto Show this year, but one of our spy shooters caught one decked out in camouflage looking a bit different than the versions we've already seen. Instead of the dual exhaust on both the turbocharged four-cylinder and twin-turbo V6, this one has a quad exhaust outlet. We'll note that the placement of the quad outlets is one and the same with the two larger outlets on the CT5 already revealed. Also, the rest of the car looks relatively ho-hum. It has the wheels from the CT5 Sport trim, and the front end appears to most closely represent the Luxury trim. Some of the coverings appear to be opened up on that front end, possibly in an attempt to increase airflow. The most obvious change of them all is the quad exhaust, though, which brings us back to a conversation we had with a Cadillac representative at the car's initial media launch. As we were standing around gawking at the new CT5 in Sport trim, a brand representative told us all the "Sport" models (four-cylinders and V6s) would be getting quad exhaust, while the "Luxury" trims would get dual exhaust. We pointed at the CT5 Sport right in front of us and noted that it just had a dual exhaust setup. This ended up causing more confusion, as the Cadillac representative was adamant that they had seen the CT5 Sport with quad exhaust. When all was said and done, there wasn't exactly a clear explanation given for what was up with this mysterious CT5 model with quad exhaust, so we left it at that. We can guess, though. Perhaps the Cadillac rep had seen a Sport model with quad exhaust, but it was a future "V-Sport" variant we weren't allowed to know of yet. Cadillac hasn't revealed its future plans for the CT5 fully, but it did hint that at least one performance variant would be on the way. This camo'd up car here does not look anything like a full-on V model, but it could be the beginnings of a slightly more powerful version of the sport sedan. The 3.0-liter twin-turbo V6 makes 335 horsepower and 400 pound-feet of torque. Of course, there's always room for more power in this class, and a V-Sport model would slot in nicely to the new sedan's range. Keep in mind this all remains speculative in nature. However, our curious conversation with Cadillac combined with these spy shots signal that something could be afoot.

GM's Buckle to Drive teen safety feature comes to more models for 2021

In 2014, GM announced a feature called "Belt Assurance," which would prevent a vehicle from being shifted out of park until the driver and front passenger had buckled their seatbelts. Initially launched on certain fleet vehicles in 2014, the feature rolled out as a free option on the 2015 GMC Sierra, Chevrolet Colorado, Cruze and Silverado. At the time, GM said it would push Belt Assurance to more models if customers took to it. That appears to have happened; come 2019, GM repackaged Belt Assurance as Buckle to Drive, part of the automaker's Teen Driver System that bundled tech such as geofencing and speed limit warnings to help parents keep track of their children's driving habits. In that implementation, the system only works when Teen Driver Mode is activated, locking out the shifter and muting the radio for 20 seconds or until the seatbelts are buckled, whichever comes first. The system shows a visual warning in the gauge cluster, too.  For this model year, the Teen Driver System came standard on 10 Chevy models, but Buckle to Drive was only allotted to the Colorado, Malibu and Traverse. Later this year, the 2021 Camaro will join the Chevys outfitted with the Teen Driver System and will get Buckle to Drive in addition. GM Authority reports that for the 2021 model year, Buckle to Drive will also be picked up by the Cadillac CT4 and CT5. Previously, the Cadillac ATS, CTS, Escalade and XTS came with the Teen Driver System, but three out of those four vehicles are no more, and the 2021 Escalade makes no mention of the Teen Driver System nor Buckle to Drive among its safety features. Elsewhere around the GM empire, the Buick Envision and Encore GX include the Teen Driver System, as do six GMC vehicles, but it's not clear when any will be upgraded with Buckle to Drive. The tech could help save numerous teenagers' lives. On its page of teen crash facts, the Centers for Disease Control and Prevention writes that roughly 300,000 teens between the ages of 16 and 19 ended up in emergency rooms to treat crash injuries in 2017. Furthermore, "only 58.8% of high school students always wore seat belts when riding as passengers," and, "Among young drivers aged 15-20 who died in car crashes in 2017, almost half were unrestrained at the time of the crash (when restraint use was known)."
