Here's the video.

I need that engine in my coupe.

 

this might be off topic but is the car color athens blue?

 

Yes, I am pretty sure that is the Athens Blue in the video.

 

i hope the car doesn't actually sound like that. the exhaust note on the g35 coupe sounded much nicer to me

 

I don't think the audio quality in that video compares to real-life...just a thought.

 

was that a freaking automatic? i thought the new G has "vtec" in it?

on all hondas w/vtec, you can actually hear and feel when "vtec" kicks in. usually at 5500 rpm. you feel a 'boost' in torque and acceleration.

 

vtec??!! this aint no civic Si bro. and no, that's a 6mt

 

Oh my...

 

when i say 'vtec', i mean the so-called variable timing and electronic lift crap you guys were talking about.

I dont see it kickin in at all. after all, it suppose to increase fuel and hp at high RPM range. that vid cleary shows it reving way past 5k, yet i dont see any differen between that and a kia with no 'vtec'.

 

Thats cause with traditional VTEC, the engagement point was fixed at a certain RPM and hence you see that sudden jump. Not sure if thats how i-VTEC and the more modern flavours work...
With VVEL, the valve lift is variable throughout the entire RPM band, and hence it appears more seamless.

 

i see, thats for clearing that up.

 

 

Oh man... -_-;

You can tell when VTEC engages because there is a mechanical difference as the engine switches to a more aggressive cam profile. This is done by the use of multiple camshafts. The more aggressive cam profiles are ideal for higher RPM ranges and typically allow some overlap during the fuel/air strokes.

VVEL operates on the same principle, but from what I've read so far, the fuel/air timing that the camshafts provide are now done in software. Moving away from mechanical camshafts which only provide static cam profiles, computer controlled timing allows the engine to dynamically remap cam profiles in real-time with exact precision to optimize timing at a specific RPM at all times. This is why it gives the new VQ an "infinite" number of cam profiles at it's disposal. Because the VVEL is able to optimize the timing to compensate for changing conditions within the entire RPM range, the engine is better able to provide a wide and flat torque curve along the 2k - 7k range.

Any corrections welcome. Hope this clears up confusion.
