Nissan made waves in the automotive world in 2007 with the unveiling of the VQ37VHR V6 engine at the New York International Auto Show. This engine debuted in the stylish 2008 Infiniti G37 Coupe, a model that has garnered acclaim for its performance and design. An essential advancement in this engine is the incorporation of Variable Valve Event and Lift (VVEL), showcasing Nissan’s commitment to innovation in engine technology.
In the same year, Nissan also launched the R35 GT-R featuring the cutting-edge VR38DETT V6 engine. This powerhouse was primarily available through specialized Nissan performance centers across Japan. The VR38 engine is distinguished by its exceptional horsepower, leveraging design elements inspired by the VQ series, along with advanced technologies like VVEL and twin turbocharging.
Engine specifications reveal significant differences between the two models. The VQ37VHR boasts a 3.7-liter displacement, while the VR38DETT is slightly larger at 3.8 liters. Both engines utilize lightweight aluminum blocks, yet they feature different stroke lengths, with the VR38DETT having a longer stroke for enhanced power delivery.
Performance data underscores the VR38DETT’s superiority. The VQ37VHR produces a respectable 332 horsepower and 270 lb-ft of torque, while the VR38DETT outshines it with an impressive 565 horsepower and 467 lb-ft of torque. This comparison illustrates Nissan’s dedication to pushing the boundaries of automotive engineering through their innovative V6 engine designs.
