Why doesn't such a big car use the CT5-V's 3.0T V6 gasoline engine? That's not very American. 🤦‍♂️ I can understand not using a V8, but going straight to a 4-cylinder, what's up with that?

I own a 2014 SsangYong Korando, 2WD high trim, 2.0 gasoline. Recently, the check engine light occasionally turns on with the error code indicating a misfire in cylinder 1. Sometimes it turns off by itself. I've swapped spark plugs between cylinder 1 and 2, ignition coils between cylinder 1 and 3, and even swapped the injectors. I planned to use elimination to check if it's the injector issue, but after each swap, the misfire code for cylinder 1 still comes back eventually! The engine idles with slight vibrations, but I don't feel any power loss on the highway—it easily goes over 160 km/h. Later, I measured the cylinder pressure: cylinder 1 is at 8 kg, while the others are over 10 kg. After researching online, I suspect it's an exhaust valve issue. Now I'm really torn. Should I just let it be, or go for a major repair? I read online that some people can fix it by opening the cylinder head without removing the engine. But the local big auto shop is no more, and the private mechanic suggests removing the engine, which I really don't want to do—worried it won't fit back as perfectly as the original. It's stressful because I bought this as a first car for my father, who has loved cars all his life, and now this happens. I've been to various places without a clear diagnosis. Some say it's slight cylinder wear, some say valve leakage, and others mention cylinder head design flaws. Any advice from fellow Korando owners on how to solve similar issues would be greatly appreciated!

I understand you're curious about the power ratings of the MC20, Roma, and McLaren GT. The Maserati MC20 with its 3.0T engine is rated at 630 horsepower, while both the Ferrari Roma 3.9T and McLaren GT 4.0T are rated at 620 horsepower. It's understandable to question if the MC20's rating might be inflated, but manufacturers use different technologies and engineering approaches to achieve their horsepower figures.
