In this video, Dr. Günter Karl explains the process in detail, with the aid of a cutaway engine. As Dr. Karl points out, the technology is currently still in the experimental stages. Test engines have been fitted to a number of cars, however, including the F700 concept and an S-Class, the latter achieving 39mpg (6.0L/100km) and 238hp (175kW) from a mere 1.8L engine. Two-stage turbochargers, direct injection and controlled auto-ignition make for a very interesting use of four minutes.
