How to interpret car specs

Unless you’re already an automobile aficionado, those charts might’ve looked like complete gibberish. Here are some essential definitions that can help you better interpret your car’s specs:
  • Base curb weight: This measurement will refer to
    the vehicle’s weight
    with a full tank of gas and only the standard equipment. 
  • Dimensions: We suggest comparing the interior and exterior dimensions to those of a vehicle you’re already familiar with, so you can get a general idea of the Audi S4’s interior and exterior sizing. 
  • Drivetrain: This is the system in your car that connects the motor to the drive axles. Some cars are front-wheel drive, some are rear-wheel drive, and some are all- or four-wheel drive.
  • Engine displacement
    : This measurement tells you the volume taken up by your engine’s cylinders—or, put simply, it tells you how big your car’s engine is
  • Ground clearance: This measurement is essential to know if you plan on taking your vehicle off-road as it measures the distance between the ground and the lowest point on your vehicle’s chassis. 
  • Horsepower: To be specific, one horsepower refers to the power needed to raise 500 pounds by one foot in a single second. Basically, horsepower tells us how powerful an engine is.
  • Torque:
    partners with horsepower and measures how good the vehicle is at spinning its wheels. 
  • Turning diameter: Measures the smallest semicircle a vehicle can make in order to complete a U-turn.
