To prove how easy it is to drive their new trucks, Swedish automaker Volvo transformed the steering wheel of one of their big rigs into a hamster wheel and let a tiny rodent steer the vehicle up a narrow quarry road.

Volvo’s new Dynamic Steering uses an electric motor to replace the driver’s muscle power, making even large trucks like the Volvo FMX a breeze to steer. Turning the wheel becomes an effortless affair, and in their latest advert, the automaker proved even a tiny hamster can do it. The now viral clip was shot on a steep and narrow quarry road at Los Tres Cunados, in north-west Spain, and shows Charlie the hamster steering a truck while guided by a precision driver holding a carrot. After training Charlie for weeks, the team placed the pint-sized rodent inside a hamster wheel installed on the steering wheel and let him take the truck all the way up the perilous road. Sitting in the driver’s seat was stunt driver Seon Rogers, who handled the pedals and guided Charlie in the right direction by baiting him with a fresh carrot. There were a few tense moments, like when the truck hit a big rock boulder sending it crashing down into the water below, but in the end Charlie managed to steer the large vehicle across the finish line.

Clearly, the test wasn’t as easy as shown in the edited commercial video, but it’s still pretty damn impressive seeing a 175-gram hamster steering a 15-tonne truck up a narrow quarry road. It’s definitely one of the most inspired commercials I’ve seen in a while.
