The engine is going through more cycles in less time and and each cycle uses fuel. Your MPG should max out at around 55mph
Additionally, higher speeds cause a higher percentage of the fuel you burn to go towards overcoming wind resistance. From 55 - 60 MPH (approx. 88 - 96 km/h), 50% of the fuel you expend goes towards powering the vehicle, and the remaining 50% goes towards overcoming wind resistance. As you increase your speed beyond that, the amount of fuel needed to overcome wind resistance increases.

What happened to cars over time?
Cars have become faster and more efficient when it comes to fuel. Cars have also become bigger, allowing more people to ride at the same time.
Why does the speed of a moving car increase when the driver applies more force on the accelerator?
When you step on the gas pedal, it injects more fuel into the car engine, causing the piston to move faster. The faster the piston moves, the faster the wheels will turn.
Differences between cars in the past and the cars in the present?
they are faster bigger more efficient easier to drive and more expensive (mostly) and more faster
Why is an aircraft likely to burn more fuel the faster it flies?
Because the airoplane is going faster and faster so it uses more fuel
Do cars use more fuel to start than idle?
Modern fuel injected cars, no.
How have cars changed since 1900?
Over the years, car designs have changed. Now there are also fuel efficient cars and with more accessories to offer like GPS, air bags, and power locks.
How has the driving age limit changed in GB in the last hundred years?
There have been changes to the speed limits in Britain for several reasons. The amount of cars on the road (which has increased dramatically), the age limit for driving which has changed because cars are cheaper and younger people can afford them and the types of cars that are on the road e.g 4X4, Vans, lorries, Super cars and standard cars. Cars have been developed more and more over the last hundred years which means they can go faster and faster due to better fuel consumption and fuel usage
Do cars go faster with more cylinders?
yes it goes much faster
How can yeast produce fuel for cars?
There are many products that can be used as fuel for cars. These products are more natural and better for the environment than fuel. Yeast can be used to produce fuel for cars by breaking it down.
Explain why a high-speed collision betwwn two cars wodl cause more damage than a low-speed collision between the same cars?
EK=.5mv(squared)The faster something is moving, the more energy it is considered to have. When two objects collided, that energy doesn't just go away, it needs to be transformed or transfered, and that is exactly what happens.When 2 vehicles collide, the kinetic energy they had is used to bend metal, create heat, and do other destructive things. The faster the cars are moving, the more energy they have, and the more energy for destruction they have.
Why do car designers like to reduce air resistance on cars?
They do it because it makes the car faster and more fuel efficient as it is not having as much resistance pushing against it.
Why does an engine turn faster as the throttle is opened?
With an open throttle the engine can get more of the fuel-air mixture into it. With more fuel to burn it will run faster.
