so beautiful

 

It said that there is a 1 sec difference from the VQ35DE and the VQ25HR?!?!

 

Sounds like more Wards awards.

That's very impressive to have 10% improved fuel economy and that SULEV.

Sweet sound too.

 

Looks like Nissan has another winner and made a good engine even better.-- (more gas mileage too).

Good to hear.
