Default Auto transmission for S2000

According to the Sunday Telegraph (Sydney Australia) the auto for the S2000 will be a "ZF self-shift 6 speed as used in the BMW 7 series".

If it comes with the five sport settings and the auto launch control I would have to pick one up.

Yea, but they don't use torque converters... the auto s2k will have a torque converter. So instead of dynoing at 200 hp like a normal s2000, they will dyno around 160-170 due to the auto sapping power.... :snooze:

hopefully they will stroke it a little to give it more displacement and torque on the Auto models.

The automatic transmission version of the NSX has 38hp less than the 6spd version.

Personally, the last thing in the world I want is a slushbox S2000.

Yea, and thats BEFORE the extra power loss due to an automatic.

So does anyone know what sort of tranny the ZF is?

Is it wet (nasty torque converter) or dry (automatically operated clutch plates)?

I mean, there's bugger all point in talking about power loss in a torque converter if it doesn't have one!

Well, in answer to my own question:

Six-Speed Automatic Transmission
It had to happen sooner or later, and BMW's new 745i will be the first car with a six-speed automatic transmission when it arrives here next year. Besides offering an additional forward speed, the six-speed supplied by transmission maker ZF is 18 percent lighter and more compact. The size and weight reductions have been realized partially through the elimination of mechanical locks, and the use of a composite, rather than metal, sump.

Besides being smaller, the new transmission is also more efficient than the one it replaces. Thanks to the additional gearset and a [red]torque converter[/red] that essentially disconnects from the transmission when the car is idling at a standstill, BMW realizes about a 3 percent increase in fuel efficiency. To prevent the car from rolling backward on inclines at stops, the brakes automatically stay engaged
