IC Engines for 100 Miles/Gallon Cars

The task of “Around the world in 80 days on 1000 liters of fuel” was successfully accomplished on the 3^rd of August 2000. Volkswagen has set up a formidable record with its Lupo 3L TDI, the world's first ever 3 liters car. In 80 days this car traveled 33333 kilometers across 5 continents using only 792.57 liters of fuel. 2.38 liters per 100 kilometers, equal to 98.9 miles/gallon, at an average speed of 85.6 km/h, what has never been done before. Beside other features of the car and the drive train, credit must be given to the 1.2 liter Diesel engine equipped with Unit Injectors. Further improvement of the fuel consumption and emissions might be reached with Diesel-like and S.I.-like Stratified Charge engines as discussed in this paper.
