The G90 is the "ultimate executive sanctuary." The rear-wheel steering makes this 5-star beast surprisingly agile in town. The "Mood Curator" and 23-speaker audio system create a 5-star atmosphere for my post-work decompression. I average 8.8 km/l. It’s a 5-star flagship that prioritizes comfort and "quiet luxury" above all else. Truly a 5-star alternative to the S-Class for the discerning professional.
