What Does “QX” Stand for from INFINITI?

If you’ve ever wondered what the “QX” means on an INFINITI vehicle like the QX50, QX60, or QX80, you’re not alone. Contrary to popular belief, it’s not an acronym for “Quality Crossover” or “eXtra Luxury.” The truth is much simpler—and more strategic. “QX” is the official prefix INFINITI uses to designate its SUV and crossover lineup, distinguishing them from sedans and coupes, which carry the “Q” prefix instead.

And for drivers in El Paso, Chaparral, and San Pablo, we’ll highlight which INFINITI QX model might be the right fit for your lifestyle.

What Does “QX” Mean in INFINITI’s SUV Lineup?

The “QX” badge is easy to spot, but its meaning isn’t always clear. Many drivers ask, what does QX mean in INFINITI? or what does QX stand for INFINITI? The truth is simple. “QX” is not short for anything. It’s a code that tells you one key thing—this vehicle is an SUV or crossover. INFINITI made this change in 2014. Before then, names were based on engine size. That method worked, but it was hard to keep up with as engines changed. So, INFINITI created a clear, new naming system.

The Q vs. QX System

This new system splits INFINITI models into two groups:

All SUVs and crossovers now start with “QX.” That includes models like the QX50, QX60, and QX80.

What the Numbers Mean

The numbers that follow “QX” don’t stand for engine size anymore. Instead, they show where each SUV sits in the lineup. This helps buyers understand each model’s size and role.

• QX50: Small and sporty
• QX60: Mid-size and great for families
• QX80: Large and built for space and strength

This layout makes it easier to spot INFINITI QX model differences without needing to check the specs. If you're shopping for a new SUV near El Paso, Chaparral, or San Pablo, knowing how INFINITI QX models are named can save you time. Once you learn what “QX” means, the rest of the lineup makes more sense. You can go straight to the model that fits your needs—whether it’s the compact QX50, the family-ready QX60, or the full-size QX80.

Why INFINITI Chose “QX” for Its SUV Models

INFINITI didn’t pick “QX” by chance. The decision was part of a shift that started in 2014. Before that year, INFINITI used names based on engine size—like the FX35 or QX56. It worked for a while, but it also led to confusion as engines and models evolved. So, INFINITI made a change. They introduced a global naming system to create clarity and consistency across all vehicles. This new system separated cars from SUVs by using one key rule:

• Q = Sedan or Coupe
• QX = SUV or Crossover

This made it easier for shoppers to understand the lineup at a glance. It also gave each vehicle a name that aligned with its role in the brand. Many people still ask, what does QX stand for INFINITI? Others wonder, what does QX mean in INFINITI? The answer is simple. “QX” is not short for anything—it’s a label. It tells you the vehicle is an SUV or crossover in the INFINITI family. Before and After the Change:

The QX naming system also helped INFINITI give each SUV a clear place in the lineup. For example:

• The QX50 is compact and sporty
• The QX60 is midsize and built for families
• The QX80 is full-size and made for maximum space and power

These changes helped remove guesswork from car shopping. You no longer have to decode engine sizes or letters. Each model’s name now reflects its spot in the lineup. This system also supports shoppers who want to compare INFINITI QX model differences. If you're shopping for luxury SUVs in El Paso, Chaparral, or San Pablo, this naming style makes the process faster and easier.

What Do the Numbers in QX50, QX60, and QX80 Represent?

INFINITI SUV names follow a simple pattern. First comes “QX,” which shows the vehicle is an SUV or crossover. Then comes a number. But what does that number mean? Some drivers think the numbers show engine size, like in older INFINITI names. That’s no longer the case. Today, these numbers show how each model fits within the lineup.
