Neither technician is correct it is because vehicles that are capable of using 83% ethanol are called flex-fuel vehicles and such vehicles are able to achieve 100 horsepower.
Flex fuel is an alternative fuel prepared with a combination of ethanol and gasoline. Flux fuel vehicles are vehicles that have internal combustion engines made to operate on more than one type of fuel - gasoline and any blend of gasoline and ethanol up to 83%. Ethanol contains a higher octane number than gasoline so flex-fuel vehicles that use up to 83% ethanol to run have increased power and performance (100 horsepower).
So both technicians a and b are incorrect as per discussion vehicles that are able to operate on 83% ethanol are referred to as flex-fuel vehicles and those vehicles are able to provide 100 horsepower.
