It's certainly *fun* to downshift and wring out a peaky motor, but when I'm not being a hooligan I certainly prefer a motor that gives me power to pass without downshifting. Heck at the track in that tight hairpin, or at the local AutoX I'd prefer to stay in a higher gear if I can  |
Because at the end of the day, there is no replacement for displacement....
The wide, flat torque curves are actually manufacturers chasing emissions and MPG ratings, rather than "driveability", for the most part. I wouldn't call a EJ257 with a powerband of 4k-6k wide and flat
Or a 4G63 in an Evo. Or the M133 in the CLA45 AMG.
I do agree, big flat powerbands are nice for street driving, but I don't think that's why most people decided to purchase a FRS/BRZ.
The big difference in driveability is not that the Innovate makes more power down low, but that the Innovate's throttle tip in is ultra aggressive. If you do a 20-80 3rd gear (MT) pull in a Vortech vs Innovate car, the Innovate never pulls more than about 3-4 feet before the Vortech starts reeling in the Innovate car.
Likewise, if you do a 20-80 pull in a VQ35DE 350Z vs AP2 S2000, the 350Z doesn't actually ever get more than about 5 feet ahead, before the S2k wizzes by.
In both cases, the Innovate and 350z *feel* subjectively much more powerful at low RPMs.
In my case, I'm never in the 1500-2500RPM range unless I'm strictly cruising; downshifting to accelerate comes naturally to me, and a 3 gear downshift isn't out of the ordinary when I'm driving.
Why do you prefer to not downshift for a pass street driving? Inconvenience? An Auto (or twin cluch in some other platforms) would fix that...
Different strokes for different folks.
