The difference is massive; the 2026 BMW ALPINA XB7 boasts 188 more horsepower than the 2025 Mercedes-Benz G-Class (631 hp vs. 443 hp), meaning the XB7 will provide noticeably faster acceleration and passing power on the highway.

The G-Class is slightly smaller overall at 190.0 inches long compared to the XB7's 203.9 inches, but the G-Class's extreme height (77.7 inches) might make navigating low clearance parking garages a concern.

What is the fuel consumption penalty for choosing the more powerful ALPINA XB7?

While specific MPG data for the XB7 isn't listed, the G-Class only achieves 18 MPG combined (17 City/19 Highway), suggesting both thirsty vehicles require premium fuel, though the massive power gap implies the XB7 will likely consume more fuel.
