unleaded gasoline
yes definently cars need to run on the specified petrol type (e.g unleaded) because the motor is made specialy to run on that fuel
1889 Benz of Germany
Since cars were first made tires were always rubber.
In the early 1900's cars were hard to control(no electric steering),used leaded gas, and were made from cheap parts(some companies) Todays cars have electric steering, high grade materials, and use safe unleaded gas.
Unleaded, most vehicles manufactured post 1983, particularly Japanese are made to run on Unleaded
Steel is strong and durable. Steel is also easy to mold into different shapes. Cars are also being made out of aluminum, plastic, and carbon fiber.

Unleaded gasoline is regular gasoline. Lead used to be added to gasoline to prevent engine knocking but the practice has been banned in most developed countries. 2nd Answer: There are some engines, a lot of them not in cars, that are made to use regular gasoline. They are designed so that the lead in regular old gasoline will build up on certain moving parts, and keep them sealed against engine pressures. Unleaded gas is not good for this type of engine, at all.
There is no fixed answer since automobiles are constantly being made.
Because that is how they are made to run. They were added to cars to cut smog emissions and meet federal/state standards. Lead ruins the catalyst in the converter.
Multiple reasons. You wouldn't want to be driving a original Ford, now would you? Reason 1: Speed. Cars were made faster, so people can get more places in less time. Cars at the upper echelon continue to become faster. Reason 2: Safety. Cars are constantly being made more safe, so less people will be injured/killed in the event of a car crash, and less car crashes will occur. Reason 3: Comfort. Cars used to be pretty uncomfortable! Cars are being made more comfortable, for both the passenger and the driver Reason 4: Entertainment. Cars used to not have TV, or satellite radio! Cars are being made more entertaining everyday! Reason 5: Efficiency. Car parts have changed to become more efficient, and have better fuel efficiency as well as lower material costs. Reason 6: Different Fuels: Cars have converted from leaded to unleaded fuels, and even to various electric fuels. These different types of fuels require different parts, and have different performance. Reason 7: Better roads: Roads have become overall better with greater dependence on them. Cars are designed with this in mind. Reason 8: Laws. Laws around the manufacture of cars have continued to change as needs have changed.
