2025 Mercedes-Benz S-Class vs 2026 BMW 7 Series
Comparison Overview
Choosing between the 2025 Mercedes-Benz S-Class and the 2026 BMW 7 Series often boils down to prioritizing outright prestige versus everyday practicality and budget. If you look strictly at raw power, the S-Class leads the pack with 442 hp compared to the 7 Series' 375 hp. However, this power comes at a premium, costing you an extra $18,450 upfront since the S-Class starts at $117,750 versus the BMW's $99,300 MSRP. For those focused on running costs, the BMW pulls ahead significantly, achieving a combined 28 MPG, which is 4 MPG better than the Mercedes' 24 MPG combined. While the S-Class is slightly shorter in length at 208.2 inches, the 7 Series offers nearly 7 more cubic feet of cargo space, boasting 19.1 cu ft versus the S-Class's 12.8 cu ft. The key decision rests on whether that significant power and brand cachet justify the extra cost and lower efficiency.
