In 2007, Nissan marked a significant milestone at the New York International Auto Show with the introduction of the VQ37VHR V6 engine, featured in the 2008 Infiniti G37 Coupe – a standout model in the brand’s history. This engine represented an evolution of Nissan’s acclaimed VQ platform, incorporating innovative technology such as Variable Valve Event and Lift (VVEL), enhancing its performance capabilities.
At the same time, Nissan unveiled the groundbreaking R35 GT-R, equipped with the VR38DETT V6 engine, specifically available at Nissan High Performance Centers throughout Japan. This advanced engine boasted an impressive combination of features, drawing inspiration from the successful elements of the VQ series while integrating new technologies like electronic port fuel injection and twin turbochargers.
The naming convention of the VR38DETT offers insight into its specifications, with ‘D’ indicating dual overhead camshafts and ‘E’ signifying electronic fuel injection, while the twin turbo elements emphasize its performance potential. In comparison, the VQ37VHR is tailored for high shutter responses with its internal design mirroring its predecessors.
Engine displacement figures further distinguish these two models, with the VQ37VHR featuring a 3.7-liter capacity against the slightly larger 3.8 liters of the VR38DETT. Despite sharing a similar architecture, these engines differ in weight reduction techniques, compression ratios, and the resulting power outputs, illustrating Nissan’s commitment to high-performance engineering across their V6 offerings.
**The Evolution of Nissan’s V6 Engine Lineup: Looking Beyond the Basics**
Nissan has long been a pioneer in the automotive industry, particularly known for its innovative V6 engine lineup. While previous discussions have primarily focused on the VQ37VHR and the VR38DETT engines, there are several important aspects of Nissan’s V6 evolution that highlight its engineering advancements and strategic direction.
Key Questions and Answers
1. **What are the main advancements in Nissan’s V6 technology over the years?**
– Nissan has consistently integrated advanced technologies into its V6 engines, such as Direct Injection, Continuously Variable Valve Timing Control System (CVTC), and VVEL. These technologies have allowed for improved fuel efficiency, increased power output, and reduced emissions compared to older models.
2. **How does Nissan’s V6 engine compare to competitors?**
– Compared to rival manufacturers like Honda and Ford, Nissan’s V6 engines often offer a balance of power and smoothness that appeals to drivers. Competitors may utilize different configurations, such as turbocharging in inline engines, which can affect performance dynamics.
3. **What are some prevalent challenges or controversies associated with Nissan’s V6 engines?**
– A key challenge has been the perception of reliability concerning older VQ engine models, particularly with issues such as oil consumption and timing chain problems. Nissan has worked to address these through enhancements in newer engines but gaining back consumer trust remains a concern.
Advantages and Disadvantages
