VQ35HR•VQ25HR Engine Technology Overview V6 GASOLINE ENGINE Advanced technology takes the next generation of Nissan’s world-renowned VQ engine to new pinnacles of high-rev performance and environmental friendliness. Nissan’s latest six-cylinder V-type Major technologies engine inherits the high-performance DNA that has made Nissan’s VQ Taking the award-winning VQ series another step series famous. Taking the acclaimed toward the ultimate powertrain, Nissan’s next- VQ engine’s “smooth transition” generation VQ35HR & VQ25HR are thoroughly concept to higher revolutions than reengineered to boost the rev limit and deliver greater ever, this VQ is a powerful and agile power, while achieving exceptional fuel economy and new powerplant for Nissan’s front- clean emissions. engine, rear-wheel-drive vehicles. Higher revolution limit By greatly reducing friction, Nissan engineers achieved a smooth transition to the high-rev limit, New VQ Engine which has been boosted to a 7,500rpm redline. Advantages Lengthened connecting rods Smooth transition up to high-rev redline Lengthening the connecting rods by 7.6mm reduces Lengthened connecting rods, addition of a ladder piston sideforce on the cylinder walls. This reduces frame and other improvements greatly reduce friction for smoother piston action to support high- friction. The result is effortless throttle response rev performance. all the way to the 7500-rpm redline. New ladder frame Top level power performance in class The lower cylinder block that supports the crankshaft Improved intake and exhaust systems, raised uses a ladder-frame structure for increased stiffness. combustion efficiency, and other enhancements This suppresses vibration to minimize friction at high achieve class-leading power. Fuel efficiency and engine rpm. emissions are also exceptional. Higher power performance Thrilling acceleration sound Power boosting technologies include a symmetrical A symmetrical intake and exhaust system helps twin intake system and continuously variable valve produce a linear and clear throttle sound in timing control systems. response to engine rpm. Better fuel efficiency & cleaner emissions The world’s first use of hydrogen-free, diamond-like carbon (DLC) coated valve lifters and other friction- contents reducing measures help raise fuel efficiency by about Higher revolution limit 4 10% and attain a class-leading emissions rating. Top-level power performance in class 6 Thrilling throttle sound Thrilling acceleration sound 8 The symmetrical intake and exhaust system Better fuel efficiency & cleaner emissions 10 configuration helps generate a stable, linear and clear sound signature for the new VQ. 2 VQ35HR•VQ25HR Engine Technology Overview Advanced technology takes the next generation of Nissan’s world-renowned VQ engine to New heights of VQ performance new pinnacles of high-rev performance Since its 1994 debut, Nissan’s VQ engine series has continued to and environmental friendliness. evolve, based on its original engineering goals of simplicity, light weight, low friction and responsive power. The VQ’s exceptional performance has put it on Ward’s 10 Best Engines list every year since the list’s inception in 1995. The Nissan VQ is the only engine to hold this record. The latest VQ in this distinguished lineage has been redesigned with new dimensions and higher rigidity, yet weight remains about the same in the 3.5-liter VQ and has actually been reduced by about 8kg in the 2.5-liter VQ, while lowering the center of gravity. The result is an even more impressive VQ powerplant. New VQ35HR VQ35DE Output New VQ35HR engine 5000 6000 7000 8000 Engine speed (rpm) New VQ25HR engine 3.
