My! Isn't it interesting? Let's face it, MB V8 5.0 is hoplessly old 
(intro'd in '90 in 500SL). That aside, I must say the Audi V8 4.2 is in 
"world class" (whatever world class means). But Audi's 5-valve just made 
in in par with "other two's" V6 2.8 -- totally dissapointing knowing Audi 
used 5-valve to let its V6 2.8 engine to breathe.

Of course, bhp is not the whole picture for an engine -- torque plays most 
of the picture. But by briefly looking at bhp/litre efficiency, why are 
Audi's more popular engines at the bottom? Oh well.


don't forget that the audi 5 valve v6 is "pegged" to 193hp due to the
german tax laws.  just as the mb 2.8 and bmw 2.8 in-line 6's are.

much more interesting is the torque curve of the 5 valve.  it's spread
over 3,000 rpm is better than the 2valve motor's peak!

and the bmw 6's are all in-line.

can't wait to try the motor to see if it's as good as leonard setright said
it was in "car".
