"The Hype Surrounding Nissan's Variable Compression Ratio Engine May Have Been Misplaced"
Nissan's variable compression ratio engine, known as the VC-Turbo, is facing scrutiny as some of these engines are under investigation by the NHTSA for catastrophic mechanical failures. The VC-Turbo engine, which was introduced in 2018, features a complex system of moving parts that adjust the compression ratio. While the technology is interesting, it has proven to be more prone to failure and less fuel-efficient than initially anticipated. The investigation includes Nissan models such as the Rogue and Altima, raising concerns about potential recalls and the cost associated with addressing these issues.
