In Germany, the auto manufacturers (Audi, BMW, and Mercedes, but I'm not sure about Porsche) got together and agreed--outside of government intervention--that cars would be limited to 250kph (155mph) in the interest of public safety.
For the '98-'00 SLK230, the top speed is electronically limited to 140mph for automatics and 142mph for manuals, according to MBUSA.<br> <br> There was a magazine article published shortly after the '01 SLK320 came out that said it's top speed was only 129mph (it's 152mph in Germany).<br> <br> The SLK32 AMG is limited to 155mph in the US and in Germany.<br> <br> So, the answer is that the '01 and up SLK230 and SLK320 might be limited to 130, but the '98-'00 SLK230 and the '02 SLK32 AMG definitely are not limited to 130.<br> <br> BTW, the '98-'02 CLK320 and CLK430 are limited to 130mph.
I was told by the dealer that my '01 is limited to 130. MBUSA said it was limited at 140. I have had it to about 135 so I know the dealer was not correct. I haven't had room or nerve to try the 140.
