The EE-9 Cascavel is a 6×6 armoured car developed in the 1970s by Engesa of Brazil. It shares many components with the EE-11 Urutu APC. The suspension includes Engesa's Boomerang double-axle rear drive.
The most common configuration, the Cascavel III, is equipped with an Engesa turret mounting a 90 mm Belgian Cockerill Mk 3 gun produced under licence.
"Cascavel" is the Portuguese word for "rattlesnake".
The EE-9 Cascavel was developed in Brazil by Engesa, S. José dos Campos (São Paulo), according to specifications of the Brazilian army. The EE-9 was designed as a replacement to the M8 Greyhound.
The EE-9 was a huge export success, being sold to numerous countries in South America and the Middle East. Most of these vehicles were manufactured in 1983.
The EE-9 is still in service in several countries and currently the Brazilian Army is running a modernisation program for the EE-9 and the EE-11, enabling them to remain in service until at least 2020.
- Cascavel I: Known as "Cascavel Magro" (Thin Rattlesnake). Initial vehicles are armed with the 37 mm gun from the old M3 light tanks.
