Before buying the V12S I had 3 V8's, I noticed kinda flat spot between about 3,500 and 4,000 RPM if holding in that range that the V8's did not have. Other V12S owners locally reported same. Anyone know why and if there is a cure without negatively affecting warranty?

 

Never noticed it on mine...

 

Spinecho... you have a V12S?

 

Yes.

 

So, when you hold a steady speed at around 3,800 RPM, the car does not seem to lurch any? You have a new V12S or a 2015?

 

2015. No lurching at 3.8K rpm.

 

OK - thanks - taking it in Wednesday for some minor warranty issues, will have them look at mine to see if there is a cure
