Blah! Gasser engines are still about 30% efficient at their very best! Usually less - and not rarely MUCH less!
Like I said, there are no production gassers that hit even 50% peak efficiency! Mazda has a prototype engine, but as mentioned it is more complicated than standard engines, and to hit beyond that you need to add WAY more complications - pneumatic valves, variable compression, and so on. That adds on tons of cost and failure points. And this is 50% PEAK! Do you understand? It's not 50% constantly, all the time, at all conditions, and only at the crankshaft! Pass through the drivetrain and it's 10-15% or more below that.
WHY BOTHER?! It's stupid. Electric motors are 90+ percent efficient essentially through the entire power range. You have instant massive, basically maximum torque from standstill; gassers have zero torque at zero RPM. Electric motors have only ONE major moving part - which spins so no vibrations, no reciprocation with associated annoying rattling and shaking and no high-wear consumable parts like drive belts, cam belts, spark plugs, oil filters, gaskets, piston rings, piston sleeves, and so on, and the vast majority of EVs have no clutches at all. Some don't even have differentials. Electric motors are also nearly silent running; gasser engine noise is a big source of stress and mental health issues with people working and living in urban areas; difficulties to relax, sleep problems and so on. Even talking near a busy street is difficult because of all the bloody noise.
Plus the pollution, as mentioned. Gasser exhaust damages the brains of human beings, it diminishes intelligence in children. This is all scientifically proven.
So tell me again why you think gassers are such a good idea. Filling up cancer juice in just 5 minutes, so you can kill yourself, everyone you care about and the rest of the planet some more? Try harder, mate!
