INFINITI Variable Compression Turbo Engine is the first ever production engine that optimises Power & efficiency.INFINITI Variable Compression Turbo eliminates the compromise between selecting either a powerful engine with lower fuel economy or a fuel-efficient engine with less engine power. Like a runner’s body, the engine’s multilink system flexes to lower the compression ratio when more horsepower is demanded and relaxes to raise the compression ratio when fuel efficiency is desired. When engine power is required, the compression ratio can lower to 8:1. When fuel efficiency is desired, the compression ratio can increase to 14:1. For all other needs, the engine can adjust to anything in between.
