Large luxury sedans are representative of the people driving them, portraying success, strength, and aptitude. But within the luxury sedan category, there are choices that reveal more about the owners of these flagship vehicles. Two of those options are the Mercedes-Benz S-Class and Audi A8, which continuously compete with one another for the attention of full-size luxury sedan shoppers. While the return of the S-Class Coupe for the 2015 model year provides drivers a larger array of options within the S-class range, we'll be comparing the 2015 Mercedes-Benz S-Class vs 2015 Audi A8 sedans. More specifically, this comparison will analyze the key differences between the similarly priced 2015 Mercedes-Benz S550 4MATIC and the 2015 Audio A8 4.0T. 

In terms of performance and power, the 2015 Mercedes-Benz S-Class has a clear edge over the Audi A8. Behind the strength of a 4.7-liter biturbo V-8, the S550 is capable of 449 horsepower and 516 lb-ft of torque. That compares quite favorably to the power of the A8's 4.0-liter turbocharged V-8 unit, which is rated for 435 horsepower and 444 lb-ft of torque. Although the compromised power figures result in a slight efficiency gain (3 mpg highway) for the A8, there is noticeably less power when you climb behind the wheel of the two models.

Differences between Mercedes-Benz S-Class and Audi A8

Although the Audi A8 4.0T begins at a slightly lower MSRP, there are noticeable benefits to choosing the Mercedes-Benz S-Class over the Audi A8. While some of those differences are intangibles, such as overall design and styling, that require consumers to get up close with the two models, The S550 features a few notable standard and available amenities that are missing in the Audi A8. Upon getting inside the Mercedes-Benz S550, drivers will immediately notice the two 12.3-inch display screens the utilize Mercedes-Benz's COMAND multimedia platform. Those crisp screens are prominent, especially when put side-by-side with the 8-inch display within the Audi A8. 

While there are multiple examples of the S-Class upstaging the A8 in terms of standard and available features, the convenience and comfort of the S-Class is also a noticeable benefit, with a larger trunk and more rear-seat passenger space.
