The core concept behind this skin is "Safety First." The design is built around the stipulations of the ECE Regulation 66—a real-world UN economic regulation concerning the strength of superstructure in buses. While the regulation governs the roll-over strength of the chassis, this skin visualizes that internal strength on the exterior.
The livery is designed to look like a mobile safety manual. It utilizes high-contrast elements usually found on heavy machinery and construction vehicles, applied here to a passenger transport setting.
The SR2 ECE R66 bus skin is far more than a metal sheet. It is a precision-engineered energy management device. It is the difference between a roof crushing passengers and a roof that folds gently, preserving a survival space. For fleet operators, respecting the integrity of this skin—from material selection to repair procedures—is a legal and moral obligation.
When you see a bus on the highway, remember that beneath the paint and livery lies an SR2 (or equivalent) structure, quietly waiting to perform its single most important job: saving lives during the unexpected. sr2 ece r66 bus skin

| Skin thickness (mm) | Max pillar intrusion (mm) – R66 | Max intrusion (mm) – SR2 | Mass change (%) |
|---------------------|--------------------------------|--------------------------|------------------|
| 0.7 | 155 (fail) | 212 (fail) | -8% |
| 0.9 | 112 (pass) | 138 (fail) | baseline |
| 1.1 | 89 (pass) | 96 (pass) | +12% |
| 0.9 + corrugation | 98 (pass) | 105 (pass) | +2% | Need to source SR2-compliant bus skins or repair
Key finding: Corrugated 0.9 mm skin meets both R66 and SR2, with only 2% mass increase over flat 0.9 mm.
