We often talk about the “best cars” in various categories, but when it comes to midsize luxury sedans, we’re truly discussing some of the absolute best vehicles on the market, regardless of class. This segment is a hotbed for innovation, frequently showcasing the newest technologies and representing the pinnacle of each automaker’s brand values and heritage. When brands like Mercedes-Benz and BMW are in the mix, the standards are exceptionally high, which explains their premium price tags. However, in this realm, spending significantly more would only yield marginally better results. Here are ten of the best midsize luxury sedans from 2017 that exemplify this exceptional class.
2017 Acura RLX
The Acura RLX champions understated excellence. For buyers who prioritize substance over flash, the spacious RLX is a compelling choice. While German competitors often garner more attention, RLX owners consistently praise their vehicles for their comprehensive strengths. Key Acura attributes like extensive features, advanced safety, sophisticated engineering, serene comfort, and impeccable quality are all standard in the RLX. It offers a refined 310-horsepower V6 engine, and a 377-horsepower hybrid variant that intelligently boosts both power and driving dynamics. For audiophiles, the optional Krell sound system, part of the Advance package, is a worthwhile upgrade, delivering exceptional audio fidelity.
2017 Audi A6
Despite being on the cusp of a model refresh (a new generation was anticipated in 2018, while rivals like the 5 Series and E-Class were newly updated for 2017), the Audi A6 remained highly desirable in 2017. The exceptional build quality and sophisticated cabin design are immediately apparent upon entering the driver’s seat. A short drive confirms its status as a leader in this competitive segment. The 2017 A6 lineup introduced a Competition variant, enhancing the supercharged 3.0-liter V6 engine from 333 horsepower to 340 horsepower. Staying current with sporty trends, it also features a flat-bottomed steering wheel. The Audi A6 continues to be recognized as one of the Best Midsize Sedans for its blend of luxury and performance.
2017 BMW 5 Series
The seventh generation BMW 5 Series debuted in 2017, continuing its legacy as a near-perfect vehicle. For years, the 5 Series has been lauded for its engaging driving dynamics—fun yet composed—combined with ample space and cutting-edge technology. This new iteration upholds that reputation. It remains a top choice for driving enthusiasts, striking a harmonious balance between agile handling and refined ride quality. Technology takes a significant leap forward in this generation, featuring innovations like gesture control for the infotainment system, remote parking capabilities (allowing the driver to park the car from outside), and integration with Amazon Alexa voice control. The range includes a plug-in hybrid model and BMW’s signature inline-6 engine, solidifying its place among the best midsize luxury sedans.
2017 Cadillac CTS
The Cadillac CTS stands out as the closest American contender to the established European and Japanese luxury brands, particularly in driving dynamics. The CTS chassis is remarkably agile, capable of maximizing the performance of its engine options: a turbo four-cylinder, a 3.6-liter V6, or the potent 420-horsepower twin-turbo V6 in the V-Sport model. Beyond performance, the CTS offers a suite of modern tech features including mobile Wi-Fi, Apple CarPlay, wireless smartphone charging, and a lavishly appointed cabin. For ultimate performance enthusiasts, the 640-horsepower CTS-V model, equipped with a supercharged V8, rivals even the formidable BMW M5, making the CTS a standout in the best midsize sedans category.
2017 Genesis G80
Genesis, Hyundai’s dedicated luxury brand, introduced the 2017 G80 as one of its initial offerings. While not entirely new, the G80 received substantial upgrades and boasts a level of standard equipment that demands attention. Luxury features like leather upholstery and navigation are standard, along with advanced safety technologies like blind spot monitoring. The cabin is exceptionally quiet, and build quality is exemplary. While some rivals emphasize sportiness, the G80 firmly prioritizes luxury and comfort. The available all-wheel-drive system is geared more towards enhanced traction in inclement weather than aggressive cornering, positioning the Genesis G80 as a strong contender for best midsize luxury sedan focused on comfort and value.
2017 Infiniti Q70
The Infiniti Q70 rightfully earns its place among the best midsize luxury sedans, though it’s worth noting its position as one of the older models in this class. The 3.7-liter V6 engine, while offering a spirited 330 horsepower, isn’t renowned for its refinement. For a more luxurious experience, the 420-horsepower 5.6-liter V8 versions are highly recommended. What distinguishes the Q70 from competitors like Lexus is Infiniti’s successful integration of driving thrills into the suspension tuning. The steering is precise, particularly in rear-wheel-drive configurations. Infiniti has also significantly improved cabin refinement, addressing previous criticisms of excessive noise, making the Q70 a compelling option in the best midsize sedan category for those seeking a blend of luxury and engaging driving dynamics.
2017 Jaguar XF
Like all Jaguar sedans, the XF utilizes extensive aluminum in its construction. This contributes to balanced weight distribution, enhancing the car’s neutral feel, which is always desirable. Coupled with a suspension system that adeptly balances comfort and precision, and potent power from a supercharged V6 engine, the XF delivers an exceptional driving experience. Its distinctive Jaguar styling further elevates its appeal, transcending the typical luxury midsize sedan description into “must-have” territory. A notable Jaguar trait is the subtle and refined operation of its electronic driver aids, in contrast to the more abrupt interventions found in some other brands. The Jaguar XF is undoubtedly one of the best midsize sedans for drivers who appreciate a blend of performance, luxury, and distinctive design.
2017 Lexus GS
While the front-wheel-drive Lexus ES caters to the softer side of luxury midsize sedans, the GS embraces a sportier character. It’s not to say the GS compromises on comfort, but rather it offers a more versatile, all-around driving experience. Over its lifespan, the GS has evolved into a serious competitor to German dominance in the segment, particularly by offering numerous standard features that are often costly options in rivals. Lexus’s renowned build quality and exceptional dealer service are significant advantages. The range begins with a turbocharged 2.0-liter four-cylinder engine producing a respectable 241 horsepower. However, for those desiring power to complement the luxury, the 311-horsepower V6 is a more fitting choice, making the Lexus GS a strong contender for best midsize sedan with a focus on reliability and features.
2017 Lincoln MKZ
Despite the MKZ name’s association with Lincoln’s less successful past models, the current MKZ represents the brand’s resurgence and was refreshed for 2017. Along with a comprehensive list of standard equipment, buyers can opt for a potent 400-horsepower turbocharged V6, creating an engaging (yet still luxurious) all-wheel-drive sport sedan. Achieving this level of power and technology in a German vehicle at a comparable price point would be challenging. Notably, the hybrid version of the MKZ is priced the same as the standard model, adding to its value proposition. The MKZ shares its platform with the highly regarded Ford Fusion, leveraging solid foundations. The Lincoln MKZ is a smart choice among best midsize sedans, offering value, power, and technology.
2017 Mercedes-Benz E-Class
The Mercedes-Benz E-Class is the quintessential midsize luxury sedan, serving as both an icon and a benchmark, and was completely redesigned for 2017. Equipping it with optional extras transforms the new E-Class into one of the most technologically advanced cars available, featuring semi-autonomous driving functionalities such as stop-and-go traffic assist and self-parking, along with sophisticated safety systems (including a feature designed to mitigate hearing damage in collisions). Even the base model excels with its elegant design, intuitive ergonomics, composed yet supple ride quality, and a refined 241-horsepower four-cylinder turbocharged engine. The lineup also includes the V6-powered E43 AMG (396 horsepower) and the high-performance E63 AMG versions (producing 563 or 608 horsepower in the S variant), which come standard with all-wheel drive. The Mercedes-Benz E-Class remains the gold standard and a top pick for the best midsize luxury sedan.
