Shown publicly for the first time on Stand B387 in Hall 5A is the latest evolution of AM General’s HMMWV, the NXT 360. Developed to meet ever-evolving customer requirements for protected light vehicles, the NXT 360 is available as either new build or a refurbishment/upgrade package for existing M1100 series users. Based on an M1151 platform, the key areas of improvement are protection (ballistic and blast), performance and mobility.

Visually, and with the exception of role-specific modifications such as the front bullbar, the most noticeable design revisions are to the bonnet and wheels/tyres.

Bonnet revisions are to accommodate the P400 engine, which is the latest development of AM General’s 6.5-litre V8 unit that powers all current HMMWVs.

The P400 is for the first time electronically controlled, and compared to mechanically controlled versions, at 250hp offers up to 60hp more, with a corresponding increase in torque.

Coupled to a six-speed development of the standard HMMWV four-speed automatic transmission, and with larger 335/65 R 22.5 Goodyear G275 MSA tyres, current testing shows improvements to fuel economy of about 15 per cent, acceleration of 20 per cent, and maximum speed of about 40km/h.

In combination with the Long Travel Kit suspension package, which offers a 40 per cent increase in wheel travel, the new wheel/ tyre combination also improves mobility by contributing to an increase in all measurable mobility angles, with underbody ground clearance increasing by 175mm.

The strengthened M1100 series chassis of the NXT 360 allows a gross vehicle weight (GVW) of up to 7,100kg, with a corresponding armour-fit dependent payload of about 1,600kg. Current M1100 series HMMWVs have a GVW of 6,396kg.
