A. cadillac's 4-6-8 had NOTHING to do with valve timing... and it wasn't a performance feature either... it WAS for gas milage and it also SUCKED hard... most people disabled it within a year... and they have NO resale value...
B. Toyota is a japanese company not american and it came out with vvti AFTER vtec...
do you have a vtec engine in your car? is so, drive it hard, really hard so that you stay in vtec almost all the time, see what your gas mileage goes to.

I have a vtec car and I do drive it hard and it gets 30 mpg EVERYWHERE... I'm also the one who said it's not for economy... it's not it's for performance... 4cyl 16 valves ALL get good milage under 2 liters and above still gets good milage.
But you are correct in saying that

^that is absolutely wrong...
Domestics are NOT typically low compression and vtec has NOTHING to do with compression. Nor is it more or less benificial to an engine based on it's compression.
I don't understand the total mis-conception when it comes to honda/import guys thinking they're high compression and domestics are low... my z6 is under 10:1 (perfectly resonable; on the high side but NOT high) there were STOCK corvettes in the 60's that had 10:1 and 11:1 and I BELIEVE even 12:1...
