Volkswagen has just unveiled what it claims is the internal combustion engine of the future. Called the Combined Combustion System (or CCS for short), it mixes the most favourable characteristics of both petrol and diesel technology to make one low emissions, high efficiency power unit which runs on synthetic biofuel. Mounted in the nose of the recently facelifted Touran, the engine was introduced to the motoring press this week.
