Nissan demonstrates sweat-sensing seats to fight dehydration

Sweat-covered seats aren’t most people’s idea of a good thing, but Nissan thinks they are. The Japanese automaker is demonstrating technology that changes the color of car seats and steering wheels based on sweat. Nissan believes this will allow the car to detect when the driver is dehydrated.

Nissan designer Paulien Routs, and Droog Design sought to show how useful sweat can be with the Nissan Juke Soak. That last part refers to the trademarked, sweat-sensitive textile material the car’s interior is coated with. You can see exactly how it works in the embedded video. Soak can also be sprayed onto clothes to give the wearer a better idea of his or her hydration level, which could be particularly useful when working out.

While the concept of car seats that change color from sweat may seem a bit silly, Nissan claims driver dehydration is no laughing matter. The automaker contends that dehydration has as big an impact on reaction times and overall alertness as drunk driving. That’s based on a 2015 study conducted by England’s Loughborough University, and funded by the European Hydration Institute, a research organization that promotes hydration.

Staying hydrated should be as important for driving as it is for any other activity, but car buyers may not be interested in seats that change colors when they sweat. Besides being a bit undignified, it’s also sort of an inefficient way to let drivers know they might be dehydrated. The color changes won’t be highly apparent if you’re sitting in the seat, after all. Drivers may also simply ignore the car’s warning about their hydration levels. Given the number of warnings and alerts modern cars are capable of emitting, that wouldn’t be difficult.

But the Nissan Juke Soak is a reminder that drivers need to do their part to keep the roads safe. A driver must be calm, alert, and awake at all times, something that is easy to forget in an age where driving is taken for granted. Everyone is responsible for making sure they are fit to drive before getting behind the wheel. That is, at least until autonomous cars arrive.

Bentley Continental GT and GTC Speed get performance boost as plug-in hybrids
Front three quarter view of the new Bentley Continental GT Speed coupe.

A few years ago, Bentley set off on a path to electrification that was paved with plug-in hybrids and added models like the Bentayga Hybrid to its lineup. However, that path was more of a parallel side road, with plug-in hybrids augmenting the lineup rather than replacing traditional gasoline-only models. Now they're heading for the fast lane.

Unveiled Tuesday, the fourth-generation Bentley Continental GT Speed coupe and GTC Speed convertible are the most powerful Bentley road cars ever — and they're plug-in hybrids. These performance models herald a new era for the Continental GT, Bentley's signature vehicle, along with its GTC convertible variant.

5 upcoming budget EVs we can’t wait for
Chevrolet Bolt EV on the beach

Electric cars are finally getting cheaper. For years, EVs were becoming more widely available -- but still at a high price. These days, the push is becoming less about simply developing an initial wave of EVs, and more about actually competing with them. Part of that has to do with price, so as we head toward a second, much wider wave of electric vehicles, we can expect to see some great inexpensive models.

There are plenty of budget EVs that have been announced and are set to roll out in the near future -- and we're pretty excited about many of them. Of course, for this piece we're being a little liberal with the term "budget." Budget for many buyers is totally different than "budget" for others. Still, here are five cheaper electric vehicles we can't wait to see on the roads.
