It's terrible for fast/smooth shifting. The only time it works is when you do drive like a grandma.

It's supposedly good for emissions. At least that's the word on the street.

Idk man. My fastest and smoothest shifts are when I shift without letting RPMs fall virtually at all. Sure, I take my foot off the gas, but I also don't wait for **** and just slam it into gear. Usually minimal driveline shock and no dumb wheel chirp like people who just flatfoot shift, but still... RPMs virtually don't drop.

Man, you guys will find a way to complain no matter what.

Manual trans basically confirmed, turbo at least 3 hunnit something horsepower. Probably great chassis and suspension. Neat throwback styling to the s30

Its the BRZ all you have been begging for.

I'm pretty excited for the reveal.

For smooth shifting you want engine RPM's to drop (not hang or even increase) after you let off the gas to enable the flywheel speed to be closer to the clutch friction plate speed. When you try to shift fast on a car with lots of rev hang you will get jerky shifts. It's strictly there for NOx emissions reduction when suddenly closing the throttle plate.

Civic SI is pretty rough too.

The problem is when you upshift, let out the clutch, and the transmission drags the engine RPM lower than where it wants to be due to the rev hang. It's an irritating form of engine braking but in reverse. There's a reason why most auto reviewers complain about it.

I test drove manual versions of 2018 WRX, 2018 Civic SI, and 2018 Accord 2.0T. I think Civic was the most fun out of those. But rev hangs and super light disengaging clutches pretty much eliminate the fun 'mechanical feeling' factor that I ended up not getting a manual car.

I thought manufacturers have to pass emission standards by averaging of their entire car lineup, not by car model. In that case, can't they just keep the manual cars fun and stop putting in stupid electric emission stuff since they sell so few manuals and wouldn't significantly impact their total emission?

Maybe I'm just less picky when it comes to what constitutes "smooth". With the cars I'm familiar with, slamming it into gear and dropping the clutch in any gear but first doesn't really shock the drivetrain much if I nail it. If I shift at improper times or I take too long to shift to the point where RPMs drop and I still try to drop the clutch without any blending, I get jerks. If I wait for syncros to match perfectly, I get smooth. If I hamfist at the peak of RPM and do my job fast enough, I still get smooth (with some stuttering in the engine, and then if I shift anywhere in the middle of that while still employing flat foot shifting, I get upsets.

Rev Hang or Rev matching really depends on the direction of the shift.

Downshifting you want the rev's to drop. Upshifting you want the Revs to go up. Which ever is needed to match the speed of the input shaft to the flywheel/clutch.

I remember the Rev Match on the 370Z being decent.

Well the last generation Z had the auto rev match system. Wouldn't that negate the effects of rev hang?

Um. What?

lmao. imagine blipping the throttle to rev match an upshift.

Youre totally backwards bud

No. Rev match revs the engine for shifting down a gear. Rev hang keeps the revs too high for too long when shifting UP a gear.

With a turbo maybe COBB can make a tune for the 400Z.. rid rev hang while at it.

I am totally backwards.

Trying to type on a phone with autocorrect and 1/2 looking at what I am typing during a meeting means I suck at multitasking.

Hopefully the point was still the same.

gratuitous pic for what they are trying to, but will ultimately fail to replicate.

people keep telling me we can never go back to light, engaging and analog sports cars and yet the MX-5 exists.

Good point. There's no reason why that formula can't be replicated in a 300hp package. Sure, it won't be as light due to heavier duty everything, but it can still be fairly light, tactile, fun to drive, and not cost $50,000.

But it helps that they've dominated that segment basically for 30 years, so they have stable footing. Other carmakers who have tried to tap into it (at least within the U.S.) haven't quite been able to replicate its success or threaten the MX-5's position. So it's not as if when the MX-5 came out, it was this huge market with ten other direct competitors that died out.
