my brother who drives an audi claims that the vtec system in the hondas and acuras is nothing special and that about 95% of all cars have this tech. just want to know why the honda VTEC is so special

 

I know that lots of other companies now use it... and that Honda wasn't the first to use it, just the first to use it widely. But Toyota, Nissan, Chevy...well, most companies make use of this technology now.

 

VTEC was pretty much the first mass-produced variable valve timing system. '89 for Japan in the Civic/CRX SiR, and '91 for the US in the NSX. The XSi, RSi, and SiR-II followed in Japan, the GS-R, Si, Ex, and VX (VTEC-E) followed in the US. Add all the other DOHC VTEC, SOHC VTEC, VTEC-E, and iVTEC models around, and Honda has the most widespread variable valve timing system.

Add to that the fact that is works better then a lot of other companies versions, and you have a winner.

 

and thats why honda is known for vtec systems

NOT toyota (i-vvt), mitsu (mivec), ford (zetec) and others

 

i think u mean VVTL-i

btw the celica uses this....makes 100 hp/liter

 

So his brother was half right. It IS in most cars, but Honda perfected it.

 

Zetec is not an engine technology. It is a name for an engine, and they really hope you'll believe there's something special about it.

 

zetec/ecotec neither of them are variable valve timing correct?

BMW has MOTEC.

-PHiZ

 

bmw had a variable valve timing controller back in 83

 

good point BUT, in the newest camry's, avalon's and lexus' use an i-vvt engine


and btw the s2000 creates 120hp/l, that is before the lattest itteration with a 2.2l engine, which has even more horsepower
