The added challenge of a flat-packed vehicle design over the already tough targets for cost,durability and weight saving made for a fascinating and stimulating journey from concept to prototype. The most satisfying elements of the project for me are that the OX will make such a difference to so many people and that it has no competitor in any part of the world. It has been a privilege to work alongside Torquil to make his vision a reality.” Professor Gordon Murray CEO & Technical Director, Gordon Murray Design THE SOLUTION • A vehicle that will provide mobility for rural areas in developing countries with poor infrastructure • Lightweight, rugged and durable to maximise payload for goods and people • Capable of operating in adverse terrain and hostile conditions • Low cost, simple maintenance and fewer parts • Designed for self-assembly using simple procedures and instructions • Supplied fully assembled or flat-packed for easy shipping and local assembly WAS BORN 10 11 PROTOTYPING AND BUILD 12 13 EXTENSIVE TESTING INCLUDING MILLBROOK, UK AND IDIADA, SPAIN. 14 15 WHY THE OX IS DIFFERENT THE PROTOTYPES PERFORMED Technical ABOVE EXPECTATIONS... n No need for 4-wheel drive n Power-train Four-wheel drive systems add weight, complexity and cost to a The current power-train is an ultra-reliable Ford 2.2l diesel n Central driving position vehicle, reduce ground clearance and increase tyre wear and fuel system.

It Three trained (but not necessarily expert) people can put an OX is then transferred to a container (six OXen to a 40ft high-cube container, together locally in approximately 12 hours. The vehicle can be three times as many as most vehicles). As well as being more ecologically supplied fully assembled if preferred. sound than assembly-line manufacture, this system means that OXen can be quickly transported to where they are needed and may benefit from reduced import duty. * Six units in 40ft high-cube container 20 21 THE DETAILS – APPROACH ANGLES, LOAD-CARRYING AND SEATING LADEN MASS AND CENTRE OF GRAVITY Approach Angles Load Path Laden-Mass Inertia Forces Load-Carrying Capacity 8 x 44-gallon drums, or 3 x Euro pallets Centre of Gravity - Fully Laden 50% 50% 45° 55° 139° 23 TECHNICAL SPECIFICATIONS 24 25 TECHNICAL SPECIFICATIONS DIMENSIONS & SPECIFICATIONS ENGINE CHASSIS Type Length 4681 mm Fuel Tank Capacity 150 Litres 4-Cylinder 16-Valve Diesel Ford PT22 Main Frame Welded Steel Sections Capacity Width 2070 mm Weight Distribution (Kerb) 71% Front 29% Rear 2198 cc Body Frame Welded Steel Sections Bore Height 2385 mm Weight Distribution (Fully Laden) 50% Front 50% Rear 86 mm Body Engineered Laminated Panels Stroke Track 1788 mm Turning Circle 11.9 m 94.6 mm Mechanically Fastened Comp.
