In late July, Nissan confirmed its new VQ35HR engine — which will appear in the 2007 G35 sedan — had achieved an SAE certified rating of 306 horsepower. Today, the automaker released a few more details:
- 10% improvement in fuel efficiency
- Super Ultra-Low Emission rating
- Smooth transition to engine speed of 7,500 rpm
- Reduction of weight and friction through adoption of asymetrical piston skirt configuration
- Reduction of piston-side force through lengthening of con rod
- Addition of rudder frame, newly-designed cylinder block with significantly improved rigidity
- Adoption of perfectly symmetrical intake system
- Adoption of continuously variable valve timing control (CVTC) for intake side and electromagnetic valve timing control (e-VTC) for exhaust side
- Reduction of intake resistance through adoption of symmetrical twin intake system and straight intake port
- Adoption of isometric exhaust manifold and perfectly symmetrical exhaust system
- Reduction of friction through adoption of world’s first hydrogen-free, diamond-like carbon (DLC) coating
- Adoption of catalyst substrate with ultra-low heat mass, super-ignition iridium spark plug and fast light-off O2 sensor control
