2014 Mercedes-Benz S-Class Review

2014 Mercedes-Benz S-Class Overview

Is the 2014 Mercedes S-Class a Good Used Car?

Absolutely, the S-Class is a great super luxury car. It’s flooded with features, maintains composure during quick turning maneuvers, and has more than enough power for any situation. However, that all comes at a price. The S-Class is one of the most expensive cars in the class.

Used 2014 Mercedes S-Class Performance and Interior

The 2014 Mercedes-Benz S-Class comes standard with a 449-horsepower, twin-turbocharged V8 engine and a seven-speed automatic transmission. The base engine enables quick passing maneuvers, but performance-oriented S63 AMG models have an even stronger 557-horsepower V8 engine that accelerates from zero to 60 mph in less than four seconds. The base S-Class delivers 17 mpg in the city and 26 mpg on the highway, which is average for the class.

This super luxury car has no qualms about making sharp turns. Thanks to a light steering system, making turns requires little effort. The standard adjustable air suspension contributes to a smooth and comfortable ride. Some models even come with Magic Body Control, which identifies bumps in the road and adjusts the suspension to smooth out the ride. Rear-wheel drive is standard, but you might find some models with all-wheel drive (4matic).

Inside, it’s easy to see why the S-class is the Mercedes flagship sedan. There is seating for five (or four in models with a rear-seat center console) and leather upholstery, handcrafted wood accents, and heated, 12-way power-adjustable front seats. Some models include niceties like massaging seats, heated armrests and doors, heated and cooled cup holders, and a cabin air purification system. There’s plenty of room in the first- and second-row seats. The standard COMAND infotainment system has user-friendly controls and crisp graphics. The S-Class has two sets of car-seat LATCH connectors in the rear outer seats.

The Mercedes-Benz S-Class comes with many standard features. These include push-button start, a 13-speaker Burmester surround sound audio system, two 12.3-inch displays, a navigation system, Bluetooth, HD Radio, satellite radio, two USB ports, dual-zone automatic climate control, and a Wi-Fi hot spot. You might even find a model with a 24-speaker Burmester surround sound audio system, four-zone automatic climate control, a rear-seat entertainment system with two displays, or a Splitview front-seat entertainment system, which exclusively allows the passenger to watch DVDs.

Should I Consider Another Used S-Class?

The 2014 Mercedes-Benz S-Class is part of a generation that started in 2014. Since the 2014 S-Class marks the first year of the generation, previous model years are vastly different. A 2015 S-Class costs a little extra, but it’s the better option. It adds a coupe body style, three new trims, a standard cabin purification system, and a standard touchpad controller. Some 2015 models even come with a head-up display. There are no notable changes for the 2016 S-Class.

Which Used 2014 Mercedes S-Class Is Right for Me?

The 2014 Mercedes S-Class comes in two trim levels: S550 and S63 AMG. You’ll be more than pleased with the base trim, but if you’re looking for even better performance, take a look at the S63 AMG. It has increased horsepower, an adaptive sport suspension, and sport seats.

You might consider a certified pre-owned Mercedes-Benz 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.

2014 Mercedes S-Class and Other Cars to Consider

Which Is Better: 2014 Mercedes S-Class or 2014 BMW 7-Series?

Three advantages the 2014 BMW 7-Series has over the S-Class include lower ownership costs, a slightly higher reliability rating, and superior fuel economy estimates. Nonetheless, the 7-Series can’t live up to the level of luxuriousness found in S-Class. Both super luxury cars have refined interiors, but the S-Class has more passenger space, trunk room, and features. Both cars have good handling dynamics, but some S-Class sedans have an upgraded suspension system that smooths out the ride over road imperfections. In terms of value, the 7-Series is the best option. Still, if you’re willing to pay more for a better performing car with a nicer interior, go with the S-Class.   

Which Is Better: 2014 Mercedes S-Class or 2014 Audi A8?

Just like the S-Class, the 2014 Audi A8 has great interior comfort, composed handling, and a host of features. On the other hand, the A8 has a smaller trunk and suffers from poor rearward visibility. Its interior has high-quality materials, but it isn’t as refined as the S-Class. The A8 does, however, tend to be much less expensive. If you're willing to spend a little extra, the S-Class is the better option. Otherwise, the Audi is a fine alternative.
