US 6.9 exhaust systems

[Oversize]

Does anyone know if the US spec vehicles had catalytic convertors fitted? I know both Aussie and US versions had emission equipment and lower compression, but seeing we didn't have CATs, would our versions have (slightly) more power??

As far as I know the US models were the least powerful.

The Euros were the most powerful.

We were somewhere in between

Hi Mark yes USA cars had cats horrible looking thing it was to .

From memory, the OZ specced cars had about 270 horses to call on - definitely more than the US versions. I think SEL69L has the correct figure. GB having the high compression engine ran about 286, but not at the back wheel. I believe about a hundred horses bolted before the gate could be shut. Regards Styria

The Australian cars produced 190 kW and about Nm 530 torque, The U.S. versions were less that this

Although....

As you can imagine I have various manuals:

Owners Manual 1 and 2: 8.8:1, 210kW, 286hp, curb weight 1935kg (DIN 70020).

Introduction into Service Manual 1975: 8.8:1, 210kW, 286hp, 550Nm, deadweight (!) 1935kg (DIN 70020),

Introduction into Service Manual 1979 (Aus): 8:1, 198kW, 510Nm, deadweight 1955kg (DIN 70020).

The last one is probably the most correct and although rather disappointing it does also state; Acceleration (load 2 persons) 0-100km/h: 7.4s!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
