Answer:
First, I'll give you some comparisons below.
Ford Mustang GT - 5.0L V8 produces 411 horsepower
GM Camaro SS - 6.2L V8 produces 426 horsepower
WINNER: Ford Mustang GT. WHY: The Mustang produces almost the same HP, with a LOT smaller engine.
Ford Mustang GT - 0 to 60 miles per hour in 4.3 seconds
GM Camaro SS - 0 to 60 miles per hour in 4.7 seconds
WINNER: Ford Mustang GT. WHY: The Mustang is faster from 0 to 60 mph and the quarter mile and it's 300 pounds lighter.
Ford Mustang GT - EPA Estimated 26 miles per gallon highway
GM Camaro SS - EPA Estimated 23 miles per gallon highway
WINNER: Ford Mustang GT. WHY: The Mustang has 3 miles per gallon better fuel economy than the Camaro.
So, what do you say? I say, "drive one!" (Ford's Slogan)
