Ford doesn't want your car seats to be ruined by a big sweaty bottom, so it's been testing its seats with a robotic version to ensure they don't crack under the strain.
The 'Robutt,' as it's brilliantly called, takes just three days to do the same amount of bum-damage as a human would manage in ten years.
Here it is in action:
The bum is "based on the dimensions of a large man" (which man, they didn't say), heated to 36 degrees Celcius, and soaked with 450ml of faux-sweat. Then it parks itself in the seat, bounces about, twists, twerks and generally does bum-related things 7,500 times.
All this isn't just to make a hilarious video (although we did have a good chuckle, we won't lie) – it's to mimic how humans use a car seat after a gym trip, run, football game or really stressful date.
Sweatproofing is obviously especially important this month, when all of us flabby gits hit the gym to try and work off those festive profiteroles, but don't want to derobe in the gym shower and so get back in our cars, drenched and panting, to wash in the privacy of our own homes.
RoboBum Wrangler Development Engineer, Body and Chassis Labs at Ford of Europe, comments:
"Cars are a part of our everyday lives, and at this time of year in particular, so is exercise. The ‘Robutt’ is a great way to check our seats will look good for years to come."
Of course, anyone who's been to Ikea knows robottoms aren't new: lots of companies use them to simulate human butt action while testing their products. Ford's was first introduced last year for the Fiesta, and after a successful trial, it's now being rolled out to all Fords in Europe.
Sadly you don't get one free with the car, though: you'll just have to make use of the nearest 'large man' if you want to test your car's bumability for yourself.
