Nissan marked a significant milestone in automotive engineering with the unveiling of the VQ37VHR V6 engine at the 2007 New York International Auto Show, debuting in the stylish 2008 Infiniti G37 Coupe. This engine represents an evolution of the successful VQ platform, showcasing advanced features like Variable Valve Event and Lift (VVEL), which enhances performance in a manner akin to Variable Valve Timing systems used by other manufacturers.
In the same year, Nissan launched the iconic R35 GT-R, equipped with the innovative VR38DETT V6 engine, which is available through dedicated Nissan High Performance Centers in Japan. This engine generates remarkable power thanks in part to its twin turbochargers, high-performance design elements, and the incorporation of VVEL technology alongside electronically managed port fuel injection.
These engine names provide insights into their specifications. The VQ37VHR denotes a displacement of 3.7 liters while the VR38DETT offers slightly more at 3.8 liters. Both engines are constructed from lightweight aluminum and share a similar cylinder diameter; however, the VR38 features a longer stroke that contributes to its power output.
The performance distinctions between these engines are striking. The 2020 Nissan 370Z, powered by the VQ37VHR, produces 332 hp, whereas the more robust 2024 Nissan GT-R with the VR38DETT delivers an impressive 565 hp. Models under Nissan’s NISMO brand further enhance this performance, demonstrating the brand’s commitment to high-octane power and engineering excellence.
Exploring Nissan’s Powerful V6 Engine Innovations
Nissan’s commitment to engineering excellence is evident through its innovative V6 engines, particularly represented by the VQ and VR series. These engines have not only served as a foundation for performance vehicles but also exemplified technological advancements in the automotive industry.
What are the most significant innovations in Nissan’s V6 engines?
Nissan has incorporated several key technologies into its V6 engines, most notably the VVEL (Variable Valve Event and Lift) system which optimizes airflow for enhanced combustion efficiency. Additionally, the integration of turbocharging, as seen in the VR38DETT, significantly boosts power output while maintaining fuel efficiency. Moreover, the use of lightweight materials has resulted in better handling and overall vehicle dynamics.
Key Challenges and Controversies
