OK, I checked. The Acura Integra GS-R needs 6200 rpm to reach its
torque peak of 128 lb-ft. At lower revs, the Acura would definitely
be quite "soft" compared to the Audi!
I have to admit that the Audi non-turbo 20V four may not be a pavement
burner, but my point is that Audi (and VW, and for that matter most
German car makers) have engines that are designed with many factors
carefully taken into consideration: real world driveability, economy,
emissions, longevity, etc... Audi is usually very conservative with
their street engines; and that's the reason we see so many Audis
with 300K+ miles and still running strong.
Acura's Integra GS-R is a good example of marketing-driven engineering.
That 170hp sounds mighty good to Joe Consumer (A higher horsepower
number must be better isn't it?), and I bet those 170hp helped them sell
lots of cars too. Too bad, because because Joe Consumer might not even
notice that his 170hp is slower than other cars with a smaller horsepower
figure... I also question whether he'll still have those 170 horses
after years of prolonged revving. Oh I forgot, it doesn't matter, because
by the time the Acura gets to be a couple years old, a newer and
"better" Acura will be waiting...
