There’s a strange contradiction happening at the front of modern cars. Engines are getting more efficient, electric vehicles need less cooling than traditional gas-powered cars, and aerodynamics are more important than ever. Yet somehow, the grilles keep getting bigger.
From BMW’s enormous kidney grilles to Lexus’ increasingly aggressive spindle design and Mercedes’ giant illuminated faces, automakers are turning the front of the car into one of its most dramatic features. And while some of that extra real estate serves a purpose, a surprising amount of it is about something else entirely.
Bigger Doesn’t Always Mean More Cooling
The obvious explanation for a larger grille is cooling. Internal-combustion engines generate significant amounts of heat, so they need airflow through the radiator and other cooling systems.
But there’s a catch: a grille doesn’t necessarily need to be as large as it looks. Modern vehicles increasingly use active grille shutters that open when additional airflow is required and close when it isn’t. These systems help balance cooling requirements with aerodynamic efficiency.
That means a giant grille can be partially or even largely decorative. In fact, automotive designer Matteo Licata told MotorTrend that many combustion-powered cars are effectively “bumper-breathers,” with much of the visible grille serving little functional purpose.
It’s Really About Making A Car Recognizable
Here’s where things get interesting: the grille has become a brand logo you can see from 100 feet away.
BMW has its kidney grille. Lexus has its spindle grille. Audi has its Singleframe. Mercedes-Benz has increasingly used large, distinctive front graphics to give its vehicles a recognizable identity.
Automakers need their cars to stand out in an increasingly crowded market, and the front end is one of the easiest places to create that visual identity. AutoWeek noted that the grille has become one of the most important elements in establishing a vehicle’s character and communicating its brand.
That’s also why grille sizes have grown alongside increasingly aggressive headlights, bumper openings, and lighting signatures. It’s less about feeding an engine and more about making sure you know what you’re looking at.
SUVs Made The Grille Problem Even Bigger
The shift toward SUVs and trucks has also changed automotive design. These vehicles have taller, wider front ends than traditional sedans, giving designers more surface area to work with.
A large grille can make a vehicle look wider, taller, tougher, and more expensive—all qualities manufacturers know buyers often associate with SUVs and trucks. There are a few reasons oversized grilles work particularly well on today’s larger vehicles:
More visual real estate: Taller, wider front ends give designers room for much larger grille designs.
A tougher appearance: A massive grille can make an SUV or truck look more imposing and rugged.
Stronger brand identity: Large grilles make vehicles easier to recognize from a distance.
Premium perception: A dramatic front end can help communicate that a vehicle is expensive or upscale.
Design balance: Larger grilles can visually match the proportions of increasingly large SUVs and pickups.
BMW’s move is probably the most obvious example. The company’s newer models have pushed the kidney grille to extraordinary proportions, while models such as the X6 combine the oversized grille with active shutters that can close to improve aerodynamic efficiency. In other words, the grille has become part of the SUV’s visual muscle.
EVs Should Have Smaller Grilles, Right?
This is where the trend gets even stranger. Electric vehicles generally don’t require the same amount of cooling airflow as combustion-powered cars, giving designers considerably more freedom with the front end.
EV designers aren’t obligated to create large grilles because electric powertrains produce less heat than internal-combustion engines. That’s why some EVs have completely closed-off noses. Others, however, have gone in the opposite direction and kept—or even enlarged—the visual appearance of a traditional grille.
Mercedes’ 2027 GLC400 Electric is a perfect example. Despite being an EV that doesn’t need a conventional gaping radiator opening, it wears an enormous grille-like front panel that serves primarily as a design statement.
The irony is hard to miss: cars need less grille than ever, but designers increasingly have more freedom to make the grille look enormous.
Drivers Can’t Agree On Whether Bigger Grilles Are Better
The oversized-grille trend has become one of the more divisive subjects among car enthusiasts. In a 2024 r/cars discussion specifically asking which cars actually pull off large grilles, the post attracted plenty of debate, with Audi, Lexus, Genesis, Mazda, and Aston Martin among the brands receiving praise. The thread also showed that size alone isn’t necessarily the problem—proportion and how the grille fits the rest of the vehicle matter just as much.
BMW’s enormous kidney grilles remain the biggest lightning rod. A 2023 r/cars thread about BMW reportedly planning to make the grille even larger received nearly 1,000 upvotes, with many commenters joking about where the trend could possibly go next.
But there’s a more serious argument behind the complaints. In a 2022 r/cars thread asking how large a grille actually needs to be, enthusiasts questioned the growing use of oversized and even non-functional front-end elements. Some commenters also pointed out the irony of EVs retaining traditional grille shapes despite having different cooling requirements.
And it’s not just BMW. A Reddit discussion about Lexus’ oversized grilles received more than 4,700 upvotes, after Lexus acknowledged that some customers considered its large spindle grilles a turnoff. Yet the company wasn’t abandoning the design, instead looking for what it called the “right balance.”
While big grilles are polarizing, they are memorable. Enthusiasts may love or hate them, but a giant BMW kidney grille or Lexus spindle grille is difficult to mistake for anything else—and that instant brand recognition is precisely why automakers keep experimenting in this area.
Are Bigger Grilles Here To Stay?
For better or worse, the oversized grille has become one of the easiest ways for an automaker to make a new car instantly recognizable. That makes the trend unlikely to disappear overnight, even as designers rethink what a traditional grille should actually do.
The interesting part is what happens next. As EVs become more common and front-end designs become less constrained by engine cooling, automakers have more freedom to experiment with completely different shapes, lighting, and materials.
For now, though, the giant grille remains a simple way to make a statement, a black canvas for designers, if you like. Mercedes’ latest EVs even use illuminated grille elements to reinforce their identity, while other manufacturers are experimenting with closed panels, lighting, textures, and digital effects.
You might not love the look, but you’ll probably remember the car. That’s exactly what designers want.
