Evolution of automobiles has undergone many crucial steps to transform the initial steam driven vehile to modern 5000 cc Regera.Some of them are:

1. First benzene fuelled motor cart by Marceus in 1870's.

2. But Italians say they invented power driven carts in 1430

3. Joseph Cugnot of France created the steam propelled engine.

4. The fact that easily distilled liquids are more efficient as fuels made petrol,diesel from gasoline popular.

As the time passed,the importance added by craze for racing made the manufacturers proceed to develop the efficiency in production,raw materials consumption.

Efficiency demanded the precision in work making the manufacturers apply highly ingenious machines.

As a result,high grade cars are made available at cheaper prices.

Manufacturers turned thier focus to middle class range cars developing small cars with all facilties.

Today ,experience combined with great engineeringskills has helped improving the efficiency of cars.

A. The craze created over the racing,ease of transport facilities without physical labour,becoming the status symbol in a society,continuos growth in technology are the main reasons for evolution.

2.What are the stages of evolution of automobile?

A. Mandriven carts- animal driven carts- wind powered carts- steam propelled engines-gas powered engines-petrol fuelled engines.

3. What is the most important realisation that revolutionised the history of automobile?

A. More distillable fuels like petrol,diesel are more ideal for fuelling than other gasoline extracts.

4. Which car is considererd as the finest motor car of all times?

A. ROLLS-ROYCE.

5. What are the major developments those have been brought into the improvising of automobiles?

A.Using the most apt fuels,reducing the unwanted noise,vibrations of the body,selecting the suitable metals for lighter weight and there by increasing the efficiency .

6.What type of cars is the most popular of all economically?

A. Small range cars.Because they are developed in an all round manner both financially and luxury keeping middle class people in mind.
