Matthew DeBord on the VC-Turbo engine:
The VC-Turbo is to engines what a continuously variable transmission is to shifting gears: It can locate the ideal compression ratio for a given driving condition. Infiniti has been working on the technology for 20 years and thinks it will enable the automaker to offer better performance with a four-cylinder motor, replacing six-cylinder power plants.
What’s the ‘VC’ mean?
The VC stands for variable compression, and it means that the new motor can modulate its compression ratio to optimize its performance. According to Infiniti, it combines the torque of a diesel motor with a high-performance gas engine — minus the emissions problems that small-displacement diesels confront.
