Looking specifically at the entry-level engine configurations, the base RX 350 configurations do boast a bit more initial torque, but for drivers seeking a genuinely sporty SUV experience, the X3 delivers much quicker acceleration in both its base and performance trims. What’s more, its performance-engineered chassis is designed for sharper cornering, and it features higher maximum towing capacities across the board.

2026 BMW X3 Vs. Lexus RX 350: Exterior Dimensions

The BMW X3 and Lexus RX 350 are both highly capable midsize luxury SUVs, but they differ significantly in overall size, footprint, and athletic proportions. Take a closer look at some key BMW X3 vs. Lexus RX 350 dimensions for a better idea of what to expect on Westford roads and inside your garage:

BMW X3 Dimensions

• Height: 65.4 inches

Lexus RX 350 Dimensions
