Less power from the Internal Combustion Engine because of Emissions ? What a joke ! As cars make less than 10% of global emissions and motorcycles are in the 0,1% range if that...There is more bad air coming out of Gretas azz or polticians mouth than out of todays clean engines...Look at the new Diesels...Their tailpipe emissions are cleaner than the air in our cities !!! And C02 has nothing to do with climate change that always occurred long before people lived on this planet or the ICEngine was invented a mere 135 years ago !
