Design Philosophy Behind the L-Series

Lexus engineers faced the challenge of adding a third row without compromising the RX's sleek profile. The solution came through:

• A 5.9-inch wheelbase extension compared to standard RX models
• Strategic body panel redesign for improved aerodynamics
• Weight distribution optimization to maintain driving dynamics
