2018 Mercedes-Benz S-Class Sedan vs 2018 BMW 7 Series Sedan

The S-Class Sedan has been a flagship model since its initial debut generations ago. For 2018, the S-Class Sedan received a complete redesign with advancements in comfort, connectivity, and safety. To highlight what this incredible model has to offer, we created a 2018 Mercedes-Benz S-Class Sedan vs 2018 BMW 7 Series Sedan comparison.

We compared the base trims of the two models--the 2018 S 450 and the 2018 740i--for a fair comparison. Both models are priced in the $80,000-range, but opting for the lower starting price isn't always the best option. For example, although the 740i costs less, the S 450 features a larger engine and delivers 42 more horses under the hood. Both models accelerate from 0-60 MPH in 5.4 seconds. The stark power difference doesn't require a sacrifice in efficiency either, as both models achieve similar fuel economy ratings.
