Volkswagen is a car manufacturing company from Germany, famously producing the Volkswagen Beetle, or as you may know it, the Punch Buggy. Besides making cars that are destined to create a punching war among friends and family, Volkswagen has produced a car named the L1, or rather 'the 1-litre car'.
On a single tank of diesel fuel, the car is able to drive 100km, which is an incredibly fuel efficient turn around. Don't worry, the car is completely road safe and up to all the necessary qualifications the vehicle needs to drive on the road legally.
The reason the car can get so far on such little fuel, is through a combination of elements that make up the car. The car is made of lightweight materials, designed with a streamlined body, and with an engine and transmission designed and tuned for someone who's looking to drive cheap.
