At DSEi 2011 Supacat is unveiling the production standard Supacat Protected Vehicle 400 (SPV400), which has achieved new levels of reliability and significantly improved ride and handling as a result of an intensive year long development programme. The vehicle also features enhanced maintainability, a revised driver interface and new front end styling. The 7th vehicle at the latest configuration will be on show at stand N9-380.


Supacat has continued to rapidly develop the SPV400 to mature the design from the prototype testing phase to a production standard. Since being assessed for the UK MoD’s Light Protected Patrol Vehicle (LPPV) requirement last year, Supacat has subjected the SPV400 to over 10,000 km of reliability testing with over 70% conducted off-road, more than doubling the total trials distances undertaken during the LPPV assessment.


“The new production standard SPV400 is a significantly improved vehicle from the early prototypes. We have achieved new levels of reliability, handling and overall usability in the automotive design that surpass those required by LPPV”, said Nick Ames, Managing Director, Supacat. “This is a vastly different vehicle from the one we had twelve months ago and we’re proud of the progress we’ve made”.


Supacat continued to develop the SPV400 light protected patrol vehicle to meet international demand for this new class of vehicle in military and non-military markets. The SPV400 is one of only two vehicles to succeed in meeting the UK Ministry of Defence’s demanding requirements for its new Light Protected Patrol Vehicle (LPPV).


SPV400 Improvements


Ride and handling has been optimised considerably to increase responsiveness and improve 'driver feel'. This has been achieved by developing new suspension geometry with a new spring and damper set-up, coupled with a high pressure pneumatic system improving suspension response times and also minimizing space required for air-stowage. In addition, the vehicle is fitted with a new brake system using a Hydro-Max hydraulic boosted brake system with separate ABS. To lighten the driver burden Supacat will soon trial an ‘automatic torque sensing’ centre differential, which adjusts torque to each axle dependent on the terrain.


The interior has also undergone a number of refinements, including improved lighting. The driver interface has been revised with new instrument panel and driver control layouts with a new driver display designed to incorporate GVA (Generic Vehicle Architecture) and vehicle diagnostic systems.


Maintainability has been improved by integrating the cooling and hydraulic pipework with the cooling pack into a single module, thus allowing easier access to inspect or replace engine components. A new ground-driven steering pump has been incorporated to maintain power assistance in the event of a stopped engine, for example, if fuel runs out. A dashboard controlled Central Tyre Inflation System (CTIS) has also been fitted. Other enhancements to the pre-production SPV400 are the development of vehicle CAN (Controller Area Network) system including a battery management system, automatic park brake release, driveline control, cruise control and intelligent lighting system.


The SPV400


A light patrol vehicle in the 7.5 ton class, it carries a crew of six (2 +4) and combines an integrated blast and ballistic protection system, including a protected all composite crew pod and V-shaped hull. Using the latest composite and ceramic armour systems, the crew pod is constructed as a separate module, sealed off from potential secondary projectiles, such as kit and electronic devices, which are housed in a rear compartment. All seats are mine blast protected. Its exceptional all terrain, high mobility performance is comparable to the Supacat-designed Jackal and is capable of speeds up to 80mph on the desert plain.


A modular and future-proofed design allows the SPV400 to be upgraded to meet evolving threats and requirements. The V shaped hull protects the crew in an under-belly mine strike scenario, while the modular approach enables the SPV400 to be repaired in theatre following mine blast incidents by replacing the damaged module(s).


Air suspension provides troops with a smooth ride, reducing crew fatigue and conventional steering reduces complexity.
