Vehicle efficiency, safety, and enforcement updates

Overview

Vehicle efficiency and safety in extreme temperatures remain a primary concern. Maintaining cabin air filters and inspecting climate-control systems is essential to prevent mold and compressor failures. Experts recommend a 30-second delay before activating A/C to reduce stress. To cool cabins, the “Japanese method” of opening/closing doors can drop temperatures by 3.6 °C per minute. Recirculation mode should be limited to 20 minutes to avoid CO₂ buildup. Temperature extremes impact efficiency: cold weather can reduce EV range by ~35 %, while hot conditions reduce EV efficiency by ~10 %.

In Portugal, the GNR has intensified enforcement amid rising road fatalities. Minister of Internal Administration Luís Neves described the road situation as a “civil war,” citing driver and pedestrian incivility. Pedestrian deaths rose sharply, with 31 fatalities in the first half of 2026 compared to 14 in the same period in 2025. Overall accident data from January 1 to August 11, 2026, indicates 93,012 accidents and 302 deaths.

Enforcement has also targeted criminal activity. In Setúbal, GNR operations between September 7 and 13, 2026, resulted in 86 arrests and 801 traffic violations. In the Algarve, the GNR’s Coastal and Border Control Unit conducted an operation in Vila do Bispo and Sagres, seizing approximately 6,725 liters of gasoline in 269 jerrycans and detaining two individuals to combat cross-border fuel and drug trafficking.

On September 27, 2026, the GNR’s Coastal and Border Control Unit intercepted a fuel transfer attempt near Praia do Castelo in Albufeira, detaining six individuals and seizing approximately 200 jerrycans of fuel. This operation targeted suspected maritime drug trafficking logistics involving various foreign nationals. Additionally, GNR officers in Setúbal intercepted an illegal street racing gathering on the EN10, seizing 17 vehicles for unauthorized structural modifications.
