The Toyota/Lexus V6 is very smooth, also. It just doesn't sound as nice. The problem is that I love driving, but with fuel at sky-high prices (CA trying to get everyone to buy EVs, only), the LC500h is very tempting. (tough choice for me)
It's just too bad the LC500h doesn't really save that much on gas mileage compared to the V8
