2015 Mercedes-Benz S-Class Overview

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

Yes, the 2015 S-Class is a good option if you’re considering a used super luxury sedan. This Mercedes offers a smooth and comfortable ride, a lovely interior with top-notch materials, and a wide array of high-tech safety and convenience features. It has power to spare as well, thanks to its lineup of twin-turbocharged V6, V8, and V12 engine options.

That said, the S-Class’ ownership costs are the highest in its class. Before you buy, you may want to consider alternatives like the 2015 Porsche Panamera, which has a higher reliability rating and lower projected costs.

How Much Does the 2015 Mercedes-Benz S-Class Cost to Own?

The S-Class’ five-year costs for gas, insurance, repairs, and maintenance are projected to be about $41,400, or $8,280 per year. That’s pricier than average for a super luxury car.

Is It Better to Buy a Used or New S-Class?

The 2019 S-Class starts at around $91,000, but it can top $200,000 for the AMG trims. You can save a lot of money with a used 2015 model while still finding many of the same convenience and safety features, comparable driving dynamics, and similar engine performance. The main thing you won’t find is support for Apple CarPlay and Android Auto. For those systems, stick with an S-Class from 2018 or later.

Which Model Year of the S-Class Is Best?

The sixth generation of the S-Class arrived for the 2014 model year, and it has seen regular updates since. A two-door coupe body style debuted for 2015, along with a new plug-in hybrid and a V12-powered model. An extended-length Maybach model arrived in 2016, followed by a cabriolet body style (a four-seat convertible) for 2017. The 2018 S-Class received lightly updated styling, more-capable active safety features, support for Apple CarPlay and Android Auto, and a new V6 base model.

You may have to opt for a newer S-Class to find that certain trim, feature, or body style you want. Ultimately though, all of these models are excellent, albeit pricy, luxury vehicles.

Which Used Mercedes-Benz S-Class Model Is Right for Me?

The 2015 S-Class is available in two body styles – sedan and coupe – as well as five trim levels: S550, S550 Plug-In Hybrid, S63 AMG, S600, and S65 AMG.

Because all S-Class trims are so well-equipped, you should focus your search on models with the options and engine performance you desire.

What Does Mercedes-Benz's Certified Pre-Owned Warranty Cover?

Mercedes-Benz offers a certified pre-owned program for vehicles six years old or less and with fewer than 75,000 miles. Eligibility is determined by the vehicle’s initial sale date. 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. This warranty can be renewed for a fee. If the new-car warranty has expired, you’ll receive the one-year warranty with unlimited mileage. Every Mercedes-Benz CPO vehicle must pass a 165-point inspection.

If you’re unsatisfied with your CPO vehicle, Mercedes’ Exchange Privilege program allows you to exchange it for another CPO vehicle of equal or lesser value within seven days or 500 miles. Additional benefits like towing and 24-hour roadside assistance may be available, so read the Mercedes-Benz warranty page carefully.

Among luxury car manufacturers, Mercedes-Benz’s CPO program is about average. It’s better than BMW’s but not as robust as Jaguar’s or Lexus’, according to our analysis.

2015 Mercedes-Benz S-Class Versus the Competition

Which Is Better: 2015 Mercedes-Benz S-Class or 2015 BMW 7 Series?

The 2015 BMW 7 Series is a great option, but the S-Class is a slightly more well-rounded vehicle. Both of these cars feature punchy engines, comfortable rides, roomy seating, and many of the same safety features. One notable difference is that the BMW is available with a fuel-efficient turbodiesel engine, unlike the S-Class. However, the S-Class features a richer interior. That said, the more upscale ambiance of the S-Class carries a heftier price tag than the 7 Series.

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

The 2015 Audi A8 offers pleasant driving dynamics, powerful engines, and a host of high-tech safety features. The S-Class outshines the A8 with a more-advanced infotainment system and even nicer cabin materials. The Mercedes is the better luxury car, but at a higher price. You’re apt to pay much less for a used A8.

2015 S-Class Performance

How Does the 2015 Mercedes-Benz S-Class Drive?

The 2015 S-Class has five turbocharged engine options: a V8 with 449 horsepower (S550), a V6 hybrid with 436 horsepower (S550 Plug-In Hybrid), a larger V8 with 577 horsepower (S63 AMG), and a V12 with 523- to 621 horsepower (S600 and S65 AMG, respectively). A seven-speed automatic transmission and rear-wheel drive are standard; 4Matic all-wheel drive is available.

If this sounds like a lot of power, that's because it is. All of these engines are capable of hustling the S-Class from zero to 60 mph in under five seconds, and each provides mammoth passing power on the highway. The seven-speed transmission is a highlight as well; it earns praise for its quick yet smooth gear changes. Most shoppers will be perfectly happy with the Mercedes-Benz S550 models. These variants offer plenty of muscle, yet they still get decent fuel economy.

The S-Class is surprisingly agile and fun-to-drive for a vehicle of its size. The steering is light yet responsive, and the brakes slow the car down with confidence. The S-Class’ ride quality is even more impressive. All models are equipped with an adaptive air suspension (Airmatic), which continuously adjusts to deliver a comfortable ride no matter the road surface. For an even silkier ride, opt for a model outfitted with Magic Body Control. This system can scan the road for bumps and adjust the suspension to minimize their effect.

Does the 2015 Mercedes-Benz S-Class Get Good Gas Mileage?

The S-Class’ fuel economy varies by trim level. The standard S550 yields a decent 17 mpg in the city and 26 mpg on the highway, but the AMG and S600 models drop to between 15/23 and 13/20 mpg city/highway.

For the best fuel economy in the lineup, check out the S550 Plug-In Hybrid. This model achieves 58 MPGe and 26 mpg combined city/highway, which is excellent by class standards. This variant has an all-electric driving range of 12 miles.

2015 S-Class Interior

How Many People Does the 2015 S-Class Seat?

The 2015 S-Class is available in two body styles: a four-door sedan and a two-door coupe. The sedan has five seats, while the coupe has four. The front seats of both models are comfortable and spacious, even for tall occupants. The driving position is quite nice as well, making the S-Class a relaxing car for longer road trips. The coupe’s rear seats are similarly inviting, and they can fit two adults in reasonable comfort. The sedan’s back seat is even more accommodating, thanks to its extra 10 inches of legroom.

Both rows of seats are available with luxuries like heated, ventilated, and massaging seats. An optional Executive Rear Seat Plus package adds a rear center console, a footrest, and folding tables, but it lowers the sedan’s seating capacity to four. The S-Class’ interior is trimmed with high-end materials, and its styling blends traditional and modern elements. Its well-insulated cabin muffles out almost all wind and road noise, resulting in a whisper-quiet ride.

How Many Car Seats Fit in the 2015 Mercedes-Benz S-Class?

The S-Class has two full sets of LATCH connectors for securing child car seats.

2015 Mercedes-Benz S-Class Features

The 2015 S-Class is bristling with technology. Standard features include a navigation system, a Wi-Fi hot spot, Bluetooth, USB ports, satellite radio, a cabin air fragrance system, and two 12.3-inch displays. One screen acts as a gauge cluster, while the other displays infotainment and navigation functions.

This dual-screen setup has quick response times and sharp graphics. It can be controlled using a simple knob and touchpad on the center console, or with buttons on the dashboard and steering wheel. That said, the system can be difficult to use on the go because of its many menus and options. Available features include a head-up display, a rich 24-speaker Burmester stereo, and a pair of tablets for back-seat passengers.
