RONART F1 Junior

The F1 Junior is a unique concept in that the whole family can enjoy many years of pleasure in driving and maintaining a car for pure enjoyment. 

The car may be driven on a variety of surfaces such as grass, tarmac or rough terrain due to the excellent suspension designed for the car.

The car features a four stroke Petrol Engine using unleaded fuel and has electric start by push button on the dashboard. To make the car easy to drive there are only two foot controls, one for the accelerator and the other for the brake. The pedal controls are easily and quickly adjusted and combined with a seat inset can allow a driver of 5 years to an adult of up 5'8" medium build  drive the car comfortably. Smooth take up of drive is carried out using a centrifugal automatic clutch coupled to an automatic gearbox. This unit effectively has a 19:1 ratio at start which changes automatically up to a 0.87 overdrive ratio dependent both on torque and speed. The gearing may be set to the customers preference, i.e. a restricted max limit of 10mph may be fitted for the younger children.  

The car has a superb multi-tubular space frame chassis, rear differential, twin hydraulic disc brakes and the excellent wishbone suspension. Higher power engines are available that can make the car suitable for track racing, possibly a mini race series, driving schools and  corporate hospitality use.


Safety has played an important part in the design of the F1 Junior. The chassis is well engineered and has many safety features including roll over bar, side impact bars and front impact zone. Externally mounted master cut-out switch with removable key and the dash ignition key cuts engine power immediately and also helps prevent unauthorised use.

Speed can be restricted to a very slow speed for the younger drivers or learners but children must be totally supervised by adults at all times. Safety is of paramount importance.
