Designs have been drawn up for a radically enhanced version of the Otokar Cobra armoured patrol vehicle, based on AM General's XM1211 ECV II evolutionary concept vehicle, a growth version of the US Army's High Mobility Multipurpose Wheeled Vehicle (HMMWV). The US Army has ordered 15 examples of the ECV II, which it is due to start testing at Aberdeen Proving Ground in January 2008. Its key features include:

• increased ground clearance

• a removable parabolic-shaped blast-deflection plate under the crew compartment

• a variable-height semi-active suspension system (which can be lowered for air transport)

• a raised internal floor to reduce transmission intrusion

and a raised roofline that gives greater usable volume (5.3 m3) for the crew

It also features improved fragment and improvised explosive device (IED) protection and an uprated engine (186 kW GEP SCCS 400 turbocharged diesel) matched to an Allison 2550 six-speed electronic automatic transmission with automatic traction control and an automatic braking system.
