It's not sequential, standard H pattern with a clutch.

Besides, let's compare apples with apples, not purpose built race cars with slightly modded road bikes.
Get the mouth to put his V8 against any road bike. (I bet he hasn't got one)

Are you sure Lou? From in-car shots it certainly looks like the aussie V8 drivers are only moving the shifter forward or back, not in an H pattern.

Maybe they got a Berry & Chung inline shifter?

Any of you old farts have one in a Holden or Vauxhall?

Yep the auzzie supercars have a normal h pattern gearbox. They don't use the clutch on upchanges but do on downchanges. I'm pretty sure the clutch works the same as a conventional clutch but the gearbox is different in someway so that they can change up without using the clutch. They can also change up without lifting the throttle.

Lap records/statistics from http://www.philipislandcircuit.com.au

Motorcycle Lap Records
Class Rider Machine Time
MotoGP Melandri Honda 1:30.332
Form.Xtrm Brooks Honda 1:36.346

Car Lap Records
Category Driver Car Time
Form 4000 Wills Reynard 1:24.2215
V8 Supercars Lowndes Comm.VT 1:33.4389
GT Production Youlden AU XR 8 1:52.0907

The Formula Xtreme bikes and GT production cup V8s are probably the closest things you'll get to race modified vehicles which started off as dealer vehicles which any ordinary person can purchase.
The V8 supercars are pretty fast, even though we like to think of them as taxis, around 3 seconds per lap faster than Formula Xtreme (around the same as Troy Corsa's superbike record of 1:33.019). They would probably be considered equivalent classes, i.e. based on road-going vehicles, but in reality share few similar parts.
MotoGPs are quicker again. The Reynard 94D is an open wheeler and holds the outright lap record for Philip Island. I would expect an '06 F1 car would be faster again.

The Hollinger 6 speed comes in both specifications, i.e. H pattern or Sequential. V8 Supercars run sequentials. V8 touring cars tend to run H types.

page 26 states that they are only allowed to use H pattern gearboxes. Was pretty sure that I'd seen them using the standard H pattern from the in car shots.

No synchros, they just use engagement dogs.
