How wide is the back seat of a Chrysler 300?

The back seat width isn’t published as a single figure by Chrysler. Instead, official specs break interior space into shoulder room, hip room, and overall rear-seat width. Based on those measurements, the usable width across the back row typically falls in the mid-50s inches, with slight variation by year and trim. In practical terms, the back seat can accommodate two adults comfortably and a third passenger in a pinch.


What the measurements say about back-seat width


Automakers publish interior dimensions in related categories rather than a single “back seat width.” The figures below are the key metrics that approximate how wide the rear bench feels and how many people can sit across it.



  • Rear shoulder room: roughly 56–58 inches (about 142–147 cm) across the seating plane, which affects how wide the back row feels for three across.

  • Rear hip room: roughly 54–57 inches (about 137–145 cm) across at the hip line, contributing to comfort for three passengers in a row.

  • Overall rear bench width: typically in the 54–57 inch range (137–145 cm) between the inner surfaces of the rear trim panels.

  • Practical seating note: two adults will usually sit comfortably; three adults can fit, though the center passenger may have less shoulder space depending on trim and seat contour.


The numbers above are general ranges that apply to most Chrysler 300 configurations. Exact figures can vary slightly by generation (LX vs. LC), trim level, and optional seating features that alter cushion contour and seat side bolsters.


Year-to-year and trim variations


The Chrysler 300 has spanned multiple generations since its mid-2000s launch, with minor interior variations that influence perceived width. While the back-seat width remains broadly similar across years, small differences in seat design, door sill height, and trim materials can make the rear bench feel a touch wider or narrower. For precise figures for a specific model year and trim, consult the official Chrysler spec sheet for that year or a trusted automotive data source.


As a practical guideline, when you’re comparing used examples or shopping by inventory, check the interior measurements (rear shoulder room and hip room) listed in the vehicle’s spec page or brochure, and, if possible, test-fit with a tape measure or in person to confirm comfort for all passengers.


Summary


In summary, the Chrysler 300’s back seat width sits in the mid-50s inches range across most years, with about 56–58 inches of rear shoulder room and 54–57 inches of hip/bench width. Exact numbers vary slightly by generation and trim. For an exact figure for a specific car, refer to the official spec sheets or measure the interior yourself.

Why is the Chrysler 300 being discontinued?


The Chrysler 300 is being discontinued primarily because Chrysler is shifting its focus to new technologies, particularly electric vehicles (EVs). The company is moving away from traditional internal combustion engines to meet new market demands and regulations, and production of the 300 ceased after the 2023 model year to make way for these future models.
 

  • Shift to electrification: The auto industry is trending towards electric and more advanced vehicles, and Chrysler is following this trend. The discontinuation of the 300 allows Chrysler to invest resources into developing and producing new EVs. 
  • Focus on future technologies: To demonstrate a commitment to innovation, Chrysler is discontinuing older models to make room for new and modern vehicles. 
  • Industry-wide trend: The move aligns with a broader industry shift away from gasoline engines. For example, Dodge also discontinued its Charger and Challenger models after 2023 for a similar reason. 
  • Limited sales: Although the 300 had a dedicated following, overall sales for the line had slowed, making it less viable compared to the performance and technological advancements seen in newer models.

What is the width of a Chrysler 300?


The width of a Chrysler 300 is approximately 75 inches (190.2 cm) without mirrors, though some model years may differ slightly. Different model years and trim levels can have variations, but the typical width is around 75 inches or 190.2 cm.
 

  • Recent models (2015-2023): The width without mirrors is generally 75.0 inches (190.5 cm). The width with mirrors included can be higher. 
  • Early models (2005-2006): The width without mirrors is about 74.1 inches (188.2 cm). 
  • Older models (2005-2010): The width is about 74 inches (188 cm). 
  • Overall dimensions: For specific model years, you can find detailed dimensions including width on sites like Edmunds, iSeeCars.com, and CarsGuide. 



What Chrysler 300 to stay away from?


The Chrysler 300 models to avoid are generally the early first-generation years, specifically 2005, 2006, and 2007, due to frequent reports of transmission and electrical problems. Other years to be cautious of include 2010 for suspension and engine issues, and 2012 for its electrical system. Problems can also arise in the second generation, such as window regulators and various software issues.
 
Specific model years to avoid

  • 2005: Initial production runs experienced transmission and electrical issues.
  • 2006: Similar transmission problems as the 2005 model, along with complaints about build quality.
  • 2007: Ongoing transmission issues persisted, along with interior component complaints.
  • 2010: Red flags include reported problems with the suspension system and engine reliability.
  • 2012: Issues related to the electrical system and overall mechanical reliability have been noted. 

Other potential problem areas
  • Electrical systems: Older models are known for issues with sensors, gauges, and the UConnect infotainment system (Bluetooth dropouts, screen delamination). 
  • Engine: Both the 3.6L and 5.7L engines can experience cam and lifter wear, especially in the 3.6L which may have a faulty oil cooler. 
  • Interior components: Issues can include peeling trim, brittle plastics, and window regulator problems, especially in the second generation.
