F1 vs DCT

F1 feels closer to stick shift. DC offers a smoother ride.....if that is what you are after then get a mercedes. I prefer F1 over DC without a doubt.

 

I believe the wave of the future is DCT ...it is smoother and potentially faster shifting....if you have driven the first generation F1 type trannys, you will remember than the F1 wasnt so great until recently with the 430, 599 and now the scud....the DCTs will only get better

 

This is a look at the furure.
At the moment "only real men" drive a stick shift as it is more in tune with the car.

Couple of years down the road "only real men " will drive F1 or its variations because the double clutch system is to smooth.

Humans hate change.

Yeah and which Porsche do you wanna buy with DCT as NONE of the exciting ones have it currently, even if its potentially better

 

Is dual clutch technology banned in F1?

 

F1 cars have no use for it. They don't use the clutch except when the car is not moving. The "F1" transmission system isn't actually used in F1.

 

Right, but I meant the quicker, smoother shifts would be a plus, no?

 

if im going with new tech for paddles over 3 pedals then go newest with dct. however, porsche better replace those dct buttons with proper paddles

 

While viewing the recent F1 race on SPEED channel they showed a segment on "Racing Per Matchett" that let viewers see the inside of a F1 gear box. INCREDIBLE!! red Bull racing was the team that allowed the view. They might have the clip on SPEED website, worth digging for.

 

F1! I love the bam, bam, bam as my 430 accelerates with the go pedal flat to the floor and the blip blip blip downshifting into a hairpin. The DCT is a technological marvel but it lakes the viseral feel of the F1.

 

I thought the DCT in my GTR (sold now) was slow, out of place many times, and jerky.
I found the 6sp BMW steptronic to be faster and smoother and more accurate in the moment.
Nothing like 3 pedals though.

 

A small advantage for DCT is lack of necessity for changing the clutch. Unless someone enjoys slapping down several thousand dollars every few years for a new clutch.

the technology is pretty similar.

the street F1 is a synchronized gearbox, hence requires a clutch -- it is the electro-hydraulic clutch operation which makes the transmission an "F1" vs a 6-speed.

a racing gearbox (used even in the low level of racing i do) is a dog ring gearbox, which requires only a brief unloading of the dogs to shift. in more basic cars, this is done with a throttle lift on upshift. in more advanced cars, this is done with an ignition cut on upshift. on downshift, it requires a blip or a clutch dip.

the main differences which affect the operation are the type of engagement -- synchro vs dog ring, and how the shift forks are manipulated -- h-pattern vs sequential.

 

which in turn lacks the visceral feel of the manual 6-speed.

 

no. a sequential dog ring gearbox can shift much faster and smoother than a DSG/DCT. it's basically instantaneous (when managed by electronics).

remember, smooth on the street means smooth at part throttle. race cars do not operate at part throttle (not upshift/downshift anyway).

 

I didn't articulate well- I was thinking smoother shifts coming into corners would unsettle the chassis a bit less, and that the upshift speed would be quicker, both advantages.

 

Being told by a friend who's driven both, "F1 is giving far more fun factors, DC is too smooth".

Not sure this is true!?

 

I was recently at a Lamborghini event and this same questioned was asked of its head of R&D. His response;

1. For supercars, power-to-weight ratio means everything - DCT weighs ~20kgs more than an F1/eGear
2. F1/eGear gives "emotion" of a gear change (I particularly like this comment)

Both these factors favor F1/eGear for a performance supercar, but DCT is an advantage in a Grand Tourer where performance is less critical...Lamborghini is sticking with eGear and not considering DCT.

 

no, i got you. the DSG/DCT type transmission won't be a benefit in a race car over the standard type of gearbox used today.

IMHO, that's somewhat of a poser justification. Even most "supercars" (especially lambos) have so much extra weight (sound deadening, stereo/nav, air conditioning, windshield wiper motor, lambo push button ride height adjustment, wheels that are too big, comfortable seats, the list goes on) that the small increase from DSG/DCT is inconsequential. Also, street car suspensions are so sloppy anyway that power:weight isn't *that* critical.

I personally prefer PDK to F1. Faster smoother gear changes are what I want if I want electronics. If you want emotion you must have a stick shift and clutch pedal, period.

 

Always seems to come back to "involvement". Manual (true manual) gets my vote.

 

Yes, the buttons are ridiculous! What are they thinking? Make the tiptronic owners feel more at home?
