Does anyone here understand Japanese? What is Mizuno's (former chief engineer of GT-R) point of view between the two?
Only watched the end because I'm lazy. He's very complementary of the S Class' handling. He compares the feel of the 4 wheel steering to Nissan's HICAS system.
He says that the LS500 has been out a few years, and that it feels a little older. He praises the aero, the suspension setup and the noise suppression, which he says feel like they have been designed with care and are what we would expect from Toyota.
However, he still thinks the ride comfort and suspension setup on the Lexus could still use a little more work. This part I didn't understand fully, because it was a little technical, but he says that something about the front wishbone and camber setup in the Mercedes is more modern (a setup he says was first done in the GTR), whereas the wishbone and camber of the front wheels on the Lexus are an older style design.
Overall, he says that the whole of the S Class platform is filled with new technology and engineering (not just the fancy interior), and he says that he could feel this difference between the LS and the S Class very strongly on his drive. He hopes that Japanese cars can try hard and catch up.
