Using constructor of inherited class in constructor

Question

I'm new to C# and I am trying to create a constructor that uses a constructor of the base class. I need to set the values of Engine Class within Constructor of Car class.

Here's what I have now:

public Car (double brand, double model, double engineCap, double fuelCount, double fuelCap )
: base (SetEngine(engineCap, fuelCount, fuelCap))
    {
        this.brand = brand;
        this.model = model;

    }

    private static Engine SetEngine(double engineCap, double fuelCount, double fuelCap)
    {
        Engine engine = new Engine(engineCap, fuelCount, fuelCap);
        return engine;
    }
}

My implementation is probably wrong here. Here's the constructor of the base class:

  public Engine(double engineCap, double fuelCount, double fuelCap)
  {
      this.engineCap = engineCap;
      this.fuelCount = fuelCount;
      this.fuelCap = fuelCap;
  }

The base class of Car is Engine.

Answer 1

Just call the base class constructor with the parameters it expects:

public Car (double brand, double model, double engineCap, double fuelCount, double fuelCap ) 
    : base (engineCap, fuelCount, fuelCap)
{
    this.brand = brand;
    this.model = model;
}

Answer 2

Create instance of Engine first and then pass it as argument to car. or create engine instance in car itself and assign to protected member of base class.
