Nissan's New Corporate Engine – Improving on Perfection

Filed under: Nissan News / Infiniti News — greg @ 10:25 pm

How do you improve upon the only engine in the world to appear on Ward’s
10-Best Engines list for 12 consecutive years?

According to, Nissan has the formula:

Start with a completely redesigned cylinder block with significantly
improved rigidity, increase the redline to 7500 rpm, increase fuel
efficiency by 10%, throw in continuously variable valve timing control
(CVTC) on the intake side and electromagnetic valve timing control (e-VTC)
on the exhaust side, decrease friction through application of the world’s
first hydrogen-free, diamond-like carbon (DLC) coating of internals, add
super-ignition iridium spark plugs, and fast light-off O2 sensor
control… Whew!  That ought to do it!

The new VQ35HR engine will be used in the 2007 G35 Sedan and the 2007
350Z. The G35 Coupe will keep the VQ35DE for the time being, likely being
the first recipient of the new 3.7 liter derivation in 2008.

The letters “HR” in VQ35HR and VQ25HR stand for “high revolution” and
“high response.”  Early reports claim and even BETTER exhaust note than
the current VQ, and significantly more power…

Stay tuned for, brought to you by NICO!
