The Glanza Turbo 1.3 is a small, lightweight car with a relatively small engine. This means that it is likely to be quite fuel efficient. According to some estimates, the Glanza Turbo 1.3 can achieve fuel economy of around 35 miles per gallon (mpg).
Assuming that petrol costs £1.35 per litre, and that the Glanza Turbo 1.3 is driven an average of 100 miles per week, the cost of petrol per week would be around £38.57.
Of course, this is just an estimate, and the actual cost of petrol per week could be higher or lower depending on the specific circumstances.
