THE NORMAL IS 21 MPG
The average size of a midsize car is about 13.51 feet long. The make and model of midsize cars can affect the size also.
As an example, a 2010 Ford Focus 4 door sedan is 67.8 inches wide.
The average cost of a midsize car, in the country of China, is equal to $8000. Many automobiles in China do not have the standard equipment familiar to the average American driver.
In my opinion a midsize car is a larger sedan or a large family car, for example: Honda Accord, Toyota Camry, Nissan Altima/Maxima.
These lists exist mostly online. http://www.fueleconomy.gov/feg/best/bestworstnf.shtml is the best but http://usnews.rankingsandreviews.com/cars-trucks/rankings/Affordable-Midsize-Cars/ lists them by car type.
MPG stand for Miles Per Gallon, it tells you the average of how many miles you can go with a gallon of gasoline
Around 28 to 34 mpg
that kinda depends on what you've done with the car. but usually you get somewhere from 8 to 14 mpg
How much does a mid size car weigh
I would say that a luxury car is larger, but not nesceserrally.
This varies by race car by race car. The mpg spends on the kind of track, weather conditions, tyres, and how long the race is. Some race cars are designed for high mpg. Example is that a F1 car would do around 3-4 mpg whereas some can do as much as 60 but for oblivious reasons. The average mpg usually around 3-6 MPG.
Depends on the type car. Some cars would get close to 20-24 mpg and larger cars would get less. About 16 mpg was average.
