2015 Mercedes-Benz S-Class Overview

Is the 2015 Mercedes-Benz S-Class a Good Used Car?

The 2015 Mercedes S-Class, available as a sedan or coupe, is an excellent used super luxury car. It has exceptionally comfortable seats and an ample interior that sports plenty of standard technology. Active safety technology abounds as well. The S-Class has a wide variety of powerful engines, and reliability is good.

Used 2015 Mercedes-Benz S-Class Performance and Interior

The S-Class has a strong engine lineup. Even the S550 Plug-In Hybrid spools out 436 horsepower from its turbocharged V6, electric motor, and battery pack. The S550 has a 449-horsepower V8, while the S63 AMG packs a 577-horsepower V8. The S600 features a 523-horsepower V12, and the S65 AMG sports a V12 that puts out a searing 621 horsepower. There is no shortage of acceleration or passing power in these luxury cars built for the autobahn. Thanks to Mercedes’ Airmatic adaptive suspension, the S550 provides smooth-as-glass highway rides and precise cornering on twisty roads. An available fully adaptive suspension smooths out the ride even more by using sensors that scan the road for imperfections like potholes.

EPA estimates for the gas models range from 17/26 mpg city/highway for the base S550 to 13/20 mpg for the S65 AMG. The S550 Plug-In Hybrid is rated at 58 mpg-e, with an electric-only range of 12 miles and a combined 26 mpg from its turbocharged V6.

As powerful as the S-Class sedans and coupes are, their luxurious interiors are more impressive. The S-class sedan seats five (four with the available executive rear-seat package) and the coupe seats four. Leather upholstery and 16-way power-adjustable, heated front seats come standard. Massaging and cooled front seats, heated front and rear armrests, a power right-rear footrest, and heated, cooled, and massaging power-adjustable rear seats are available. As you'd expect, comfort and space is great regardless of seat, and even the coupe’s rear seats easily accommodate grownups. The S550 sedan has two complete sets of LATCH connectors for securing child seats in the rear outward seats.

It’s no exaggeration to say the S-Class is packed with interior features. Standard equipment includes dual-zone automatic climate control, an infotainment system with navigation, two 12.3-inch displays, and a touchpad controller that lets you write addresses and phone numbers with your finger. Also included are a 13-speaker surround-sound system, a Wi-Fi hot spot, dual USB ports, HD Radio and satellite radio. You’ll also find some models equipped with quad-zone automatic climate control, a 24-speaker sound system, a dual-screen rear-seat entertainment system, and a front-seat DVD system that allows only the passenger to watch while the car is in motion.

Should I Consider Another Used S-Class?

The 2015 S-Class is part of a generation that began with the 2014 model year and includes the 2017 model year. Mercedes added the S-Class coupe to the lineup for 2015, along with the S550 Plug-In Hybrid, S600, and S65 AMG trims. Additionally, an infotainment touchpad was added to the standard features list. There were no significant changes for the 2016 model year. If you're interested in the S550 or S63 AMG trims, you can save some money by purchasing a similarly equipped 2014 S-Class. If you have your eye on one of the other trims, however, stick with the 2015 model year.

Which Used S-Class Is Right for Me?

The 2015 Mercedes-Benz S-Class is offered in two body styles (four-door sedan and two-door coupe) and five trim levels: S550, S550 Plug-In Hybrid, S63 AMG, S600, and S65 AMG. The plug-in hybrid, as well as the S600, are only offered as sedans. The base S550 trim and its plug-in hybrid counterpart are well-equipped with luxury features like an infotainment system with a 12-inch screen, a 12-speaker sound system, and heated, power-adjustable front seats. The S63 AMG comes with an adaptive suspension and all-wheel drive, among other features. The S600 is the most luxurious of the trims. Its features include dual rear-seat entertainment screens, four-zone climate control, and heated, cooled, and massaging rear seats with footrests. The S65 AMG adds a 7-speed sport transmission and electronically adjustable sport seats with increased lateral support.

The S550, with its wide variety of standard luxury features, is a good choice for most buyers.

Even with above-average predicted reliability, you might consider a certified pre-owned Mercedes S-Class. Mercedes-Benz certified pre-owned vehicles come with the balance of the original four-year/50,000-mile new-car warranty, plus an additional one-year/unlimited-mileage warranty. If the new-car warranty is expired, you’ll just receive the one-year/unlimited-mileage warranty. Every Mercedes-Benz CPO vehicle must pass a 164-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Mercedes-Benz warranty page carefully.

2015 Mercedes-Benz S-Class and Other Cars to Consider

Which Is Better: 2015 Mercedes-Benz S-Class or 2015 Audi A8?

The 2015 Audi A8, available only as a sedan, comes with standard all-wheel drive and an adaptive air suspension that provides more confident handling than the S-Class. The Mercedes has more-powerful engines in its AMG variants, but the Audi’s base turbo V6 gets up to speed quickly and has great fuel economy for the class. If money is no object, a used S-Class is the better choice, but saving money on the A8 won’t feel like a sacrifice.

Which Is Better: 2015 Mercedes-Benz S-Class or 2015 Porsche Panamera?

The 2015 Porsche Panamera is a driver’s car. Handling is tight, acceleration is energetic, and the ride is smooth. The S-Class, on the other hand, is built for comfort, though it matches – and in some models exceeds – the Panamera’s horsepower output. The S-Class is available with massaging and reclining rear seats – two niceties the Panamera lacks. Additionally, the Panamera’s sloping roofline affects rear headroom and visibility. Overall, however, the Panamera's superior performance, slightly lower ownership costs, and almost perfect predicted reliability make it the better choice.
