The Chang’an BenBen Mini is powered by a 1.0 liter four-cylinder that poops out 70hp. Still, some think it is better to have more down force, like this BenBenman in the great city of Guangzhou who installed an actually quite advanced giant double wing on the back of his beast. Each wing is manually adjustable for maximal flexibility. Good project! The BenBen Mini has been in the news a lot lately, earlier on we met a British BenBen and one dropped in a hole.
