Active Radiator Dampers???




__________________
The active front radiator shutters (Mercedes option code 2U1, also referred to as radiator shutter or AIRPANEL in some contexts) have been offered as an optional feature on the Mercedes-AMG CLE 53 (both Coupe and Cabriolet) for all model years since its launch—2024, 2025, and 2026—but only in select non-U.S. markets.
Mercedes offers this option in markets where it provides meaningful benefits for emissions compliance, fuel efficiency, and thermal management (e.g., under stricter EU CO₂ rules). Confirmed examples from official dealer build sheets, configurators, and market-specific listings include:
.
- European markets — UK, Germany, Poland, and most other EU countries (widely listed in dealer orders and export sheets).
- Australia — Explicitly referenced in Mercedes-Benz Australia materials and pricing discussions for CLE 53 models.
- Other international markets — Malaysia, Morocco, Egypt, and similar regions (shown in regional Mercedes posts and vehicle spec sheets).
This availability has been consistent across 2024–2026 with no model-year-specific changes noted for the CLE 53. The feature is the same automatic, behind-the-grille system that improves warm-up times, aerodynamics, and cooling on-demand.The YouTube video you originally linked almost certainly features a European-spec example, which is why the shutters are visible and demonstrated. U.S. cars were engineered without this hardware from the start due to differing regulatory and market priorities.
