[3] In spring 1916, it helped with the design of a device to manoeuvre 25 tonnes (28 tons) battle tanks into position aboard railway wagons.

Later in 1916, it designed a 4-stroke crosshead-type engine for the Mark V tank which produced 150 brake horsepower (110 kW) but emitted no visible smoke detectable by the enemy.

[5] The company went on to design a 6-cylinder diesel engine producing 130 brake horsepower (97 kW) which was manufactured by AEC for use in London bus fleets.

[10] In 1941, the company developed a relief valve subsequently named "Barostat", which automatically reduced the pressure in the fuel lines as the aircraft gained altitude, thereby avoiding the risk of the engine overspeeding: the Gloster E.28/39, designed by Frank Whittle, used this device.

[22] At around the same time, the company working in collaboration with Israel Aerospace Industries, developed a semi-robotic tug, Taxibot, which clamped around the aircraft's nosewheel and was controlled remotely by the pilot; the product was intended to reduce aviation fuel consumption.

[23] The Ministry of Defence selected a vehicle developed by Ricardo and Force Protection, known as Ocelot, to replace the Snatch Land Rover in 2010.
