MOTORING NEWS AND VIEWS

This miniature motor car is believed by its inventor, Hans Berger of Ostand, Switzerland to be the first jet-propelled car in the world. This first model, is two metres long, and one metre wide. The power unit, weighing 68 kilogrammes, is positioned at the rear of the car. The turbine forces air out of the vent at the back, thus driving, the car forward. The car is named "Young Switzerland" and is capable of speeds up to 50 kilometres an hour. The six. year old daughter of the inventor is seen at the wheel-AP Photo

CORRECT OIL FOR CAR'S VARIOUS COMPONENTS

of-lubricant necessary for the various components of a car.
