The document compares three cars - a Mazda3 with a normal combustion engine, a Chevrolet Volt hybrid, and a BMW i3 electric car. It finds that the Mazda3 has the lowest upfront price but highest yearly fuel and tax costs, making it the most expensive overall. The BMW i3 has the lowest emissions but a short driving range. The Chevrolet Volt has an intermediate price, lower yearly fuel costs than the Mazda3 due to its electric engine, and a longer driving range than the BMW i3, making it the best overall value according to the analysis.

WHAT IS MY PROJECT ON?
My project is on types of cars, I will be looking a normal internal combustion engine, a
hybrid engine and a car with an electric motor.
I’ve tried to pick similar cars for each category.
The three cars I have chosen are the:
I worked out the average price by finding six prices and I calculated the Mean.

I worked out the yearly cost by the Full tank times by 52.
Charging Time
Both the Chevrolet Volt and the BMW i3 can be charged by a conventional socket, but if
you have your own parking space/garage you can have the BMW i Wallbox Pure that can
charge the BMW i3 from 0-80% is less than 3 hours or have a Home Charging Station3 for
the Chevrolet Volt for 4 hours.
Car Name Charge Time
(Normal Socket)
Charge Time
(Wallbox/HCS3)
BMW i3 7 hours 3 hours
Chevrolet Volt 6 hours 4 hours
The Chevrolet Volt charges quicker using a normal socket in comparison to the BMW i3 the
reduction in time is 14.29% which rounded down is 14%. However when using a Wallbox
the BMW is quicker to charge compared to the Chevrolet Volt - the reduction in time is
25%.

Vehicle Tax Rate
The cost of the tax for these isn’t that much only the Mazda3 needs tax of £105, per year
the Volt and i3 cost noting to tax.
Overall Costs
I will now calculate all the costs for a year to see what car turns out cheaper.

Conclusion
So as you see the Mazda3 is around 9000 pounds cheaper than the Chevrolet Volt the BMW
i3. Overall I think the Chevrolet Volt is the best car to buy, because it has the highest range
it is just under 3 times of the Mazda3 range and just over 20 times higher than the BMW i3
