Is the Acura RLX bigger than the TLX?
The RLX has historically been larger than the TLX in both exterior size and interior space, though it is no longer sold in the United States. Today, Acura’s active sedan lineup in the U.S. centers on the TLX.
How the two sedans compare in size
To understand whether the RLX is bigger, consider overall footprint, wheelbase, and passenger/cargo space as they have appeared across model years. The RLX was designed as a full-size luxury sedan, while the TLX sits in the midsize category. This distinction translates into practical differences behind the doors and in the trunk.
Exterior footprint
Historically, the RLX has had a longer overall length and a longer wheelbase than the TLX. That extra length typically results in more interior room for rear-seat passengers and a larger trunk in many model years. The TLX, while shorter, emphasizes agility and compact luxury proportions.
Below are the main points you’ll notice when comparing the two on a showroom floor or a used-car lot.
- RLX generally offers a longer overall length than the TLX
- RLX typically has a longer wheelbase, contributing to rear-seat legroom
- TLX is usually slightly more compact in width and overall footprint, aiding maneuverability
In everyday use, these differences mean the RLX feels more spacious inside and can carry more cargo, while the TLX is easier to park and drive in tight spaces.
Availability and current lineup
As of the latest model years, Acura has ceased U.S. sales of the RLX. The TLX remains the primary sedan offered by Acura in the United States, with ongoing updates and newer generations focusing on midsize luxury performance and efficiency.
Summary
In summary, the Acura RLX has been larger than the TLX in exterior dimensions and interior space, offering more rear-seat room and cargo capacity. However, the RLX is no longer sold in the U.S., and the TLX continues to be the active Acura sedan in current lineups. For buyers comparing new models today, the TLX is the practical choice, while the RLX remains a reference point for size in Acura’s historical lineup.
