Armored Vehicle Protection Levels Explained: B4, B6, B7 and VR Ratings

Armored civilian vehicles are rated by standardized ballistic tests that specify which weapons and ammunition the armor can stop. In Europe, the most common are the CEN ratings (such as B4, B6, B7) and the German VPAM “VR” levels (from VR1 up to VR14). Broadly, B4 protects against handguns, B6 against many rifle rounds, and B7 and VR9–VR10 against high-powered and armor-piercing rifle ammunition. Higher levels add weight, cost and complexity — which is why factory-armored cars like the Mercedes-Benz S-Class Guard are engineered from the start.

Exact ammunition specifications differ between standards; buyers should ask for certification documents.

What armoring involves

• Ballistic steel, composites and ceramics in doors, pillars, roof and floor.
• Multi-layer bulletproof glass, often several centimeters thick.
• Overlaps at door gaps so there are no weak points.
• Run-flat inserts in the tires. Read run-flat tires explained.
• Upgraded suspension and brakes for the added weight.
• Explosion protection in the floor on higher levels.

Factory vs aftermarket

Factory-armored cars — such as Mercedes-Benz Guard models, BMW Protection models and Audi A8 L Security — are designed and crash-tested with armor from the start. Aftermarket armoring of SUVs like the Suburban and Escalade is done by specialist companies; quality varies, so certification and reputation matter. Read armored car history.

The trade-offs

Armor adds weight — sometimes thousands of pounds — which affects braking, handling, fuel use and maintenance. Heavy glass windows may not open fully. Drivers need training for heavier vehicles.

Do executives need armor?

Most executive travel in New York does not require armor. Professional chauffeurs, route planning, discretion and secure information handling provide appropriate protection for most clients. Read duty of care in ground transportation.
