In some (most?) VW Beetle (and other) conversion,
there is no shifting since the clutch isn't used.

I'd be interested in hearing from folks if this is a
good or bad thing, if running in 2nd gear is okay, or
if shifting without clutching works fairly well, or if
you wished you had held out for a clutching
conversion.

Thanks,

Scott

Hi Scott

Welcome to the EVDL.

This subject has been beat to death repeatedly here.

Try searching the archives for "clutchless".

Here we go again... :^D

You will drive at 2nd gear either way. So that
shouldn't effect your decision.

The scary part is when you are going down the highway
and driving at 3rd gear, and you want to d/s to 2nd.

Some clutches do better than others.

I have a clutchless VW Rabbit. 2nd gear will take me from 0 to about 45mph.
When upshifting you have to "wait" a second or 2 in neutral for the motor to
spin down. Downshifting is tougher. In neutral you have to jab the "gas"
pedal to spin the motor up before you can downshift. It takes some "skill"
and its a good idea to have a tach or rev limiter so as not to blow up your
motor. If I had to do it again I would probably keep the clutch. Al

That sounds scary. With a clutch aren't there still adaptations you have to
make to your shifting technique? If you put the car in neutral to let it
coast down a hill, when you want to put it back into gear you have to rev
the motor back up to a safe RPM range?

My SAAB has a freewheel feature. What it does is throw the transmission in
and out of neutral depending on whether the car is capable of coasting when
you let off the gas, but it does result in a lot of "bucking" on level
ground and many people permanently disable it. With no regen, I was
thinking it might be good to use it (assuming it will work without the ICE)
since the motor could completely spin down on coast automatically without
using the clutch.

there's is no need to put an electric in neutral, it will not coast any
faster, remember there is "no compression" in an electric in fact you will find
that you will use your brakes more.

I definitely use my brakes more... But there *IS* a difference between
coasting with your foot off the pedal and coasting with the transmission
in neutral. The difference may not show up in all driving syles ;)

In my '87 Cabriolet I can leave my driveway, accelerate to 40MPH, and
coast about 1 mile over hilly terrain. In 3rd gear the minimum speed will
drop to about 25MPH while going up a certain hill. In neutral (or with the
clutch pushed in) the car will maintain 30MPH or better up the same hill.
Not a big difference unless there's someone else behind you...

As far as changing driving habits between ICE and electric - I don't use
the clutch during start/stop, only when shifting gears. I also hold the
clutch in when turning my EV on, just in case the motor starts randomly. I
*can* shift without the clutch, but it's not easy with my tranny. I had a
'90 Chevy pickup that shifted very well without the clutch. You could hear
the syncros spinning the motor up/down while gently moving the sifter to
the next gear. YMMV.

Speaking of bad driving habits - I've popped the clutch in my wife's car
because of my EV habits:

1) turn car on
2) put into gear
3) release clutch
4) move foot from brake to "go" pedal

I get to #3 then wonder why the car starts bucking around!
