$75,100 · SUV

$73,100 · Wagon

Comparison Overview

Choosing between rugged capability and refined efficiency often leaves buyers scratching their heads, especially when comparing two very different utility vehicles. The 2025 INEOS Grenadier, starting at $75,100, screams serious off-road commitment with its towering 80.7-inch height and standard four-wheel drive, though it pays for that stature with a steep 15 MPG combined rating. Conversely, the 2026 Audi A6 allroad, priced slightly lower at $73,100, offers a far thriftier 24 MPG combined, benefiting from its wagon roots and slightly lower overall mass. While the Audi boasts 335 horsepower and 369 lb-ft of torque compared to the Grenadier's 282 hp, the Grenadier counters with a higher, more upright stance for better approach angles. The Audi wins on long-haul running costs due to the significant 9 MPG difference.
