This is one of my favorite Honda's commercials TV. I like that Honda put a lot of thoughts into their advertising.
The story behind this ad was that Kenichi Nagahiro, Honda’s chief engine designer, hated diesel engines. When asked to design Honda’s first diesel he flatly refused, unless he was allowed to start completely from scratch. The result is one of the cleanest, most refined diesel engines on the market today. Cute bunnies, pretty flowers and rainbows show their dislike of dirty, noisy, smelly diesel engines by destroying them in exchange for something better. Brilliant!
