I know it’s just a rendering but those planetary gears look really tiny to be transmitting that much torque. And the test vehicle has only gotten up to speeds of 120kph, or 75mph. That’s basically the minimum speed on my local highways

Toyota hybrids don’t like cold weather. Ours goes from 42mpg to 35mpg. Running snow tires will decrease it more. And if you are only running those two trips, that’s kinda worst case for a hybrid. The short trip doesn’t even have time for the engine to warm up, and the long trip is going relatively fast on the highway where the hybrid system doesn’t really work
