oh yea, that EV killer ammonia engine... Likely a good one for the self driving flying cars we'll all be driving in 2 years.

In other words, it's no surprise that GAC's prototype engine is said to have been developed with some of Toyota's know-how in searching for BEV alternatives. Unfortunately, there are so many red flags and negative variables surrounding liquid ammonia that even Porsche's e-fuels, which currently cost around $45 a gallon (or 10 euros per liter), make more sense financially.Firstly, liquid ammonia is highly toxic and extremely corrosive, and on top of it, after combustion, it releases a lot of nitrogen into the atmosphere. These three reasons alone would make it non-viable as an e-fuel replacement or an EV-killer. Still, GAC and Toyota firmly believe they have solved the nitrogen-emitting part by making the prototype engine with a very high compression ratio, among other things.Secondly, the two remaining downsides are pretty much unsolvable, at least in a viable way. Can you even imagine the horror of dealing with the fuel system maintenance of an ammonia-running engine? What if that high compression isn't maintained because of some unforeseen problems with the rest of the car?It would just pollute a thousand times more than any gas-guzzling vehicle. And by pollution, I mean more nitrogen in the atmosphere, which usually results in more ozone, respiratory illnesses, acid rain, the works.The corrosive nature of the substance also makes it tricky to handle before it even gets in your fuel tank (and after). In the minds of many, an ammonia engine is another cure that somehow seems worse than the purported disease it is trying to cure. We're probably better off with dealing with the infrastructure needed for charging all the million of BEVs that are coming.
