For sale: BMW Z4 V10 with 550 horsepower

Yup, those crazy BMW fans. I have said it before and I will say it again: the bimmer fans are nuts sometimes. And this BMW Z4 with a V10 engine outputting 550 horsepower just proves my theory….well in  a way….I went a bit overboard. The regular 6 cylinder engine found in the BMW Z4 was replaced by the more powerful and larger V10 engine from the M5/M6 models, but with an increase of 43 ponies over the standard 507 horsepower. This monster Z4 is available for sale in Germany for the even more stupendous price of 97,900 euros or $138,000. No other information is available, but the rumors say that this is Hartge engine which has been used by the famous tuner in other BMWs as well. If you ask me, the owner would DEFINITELY not get the asking price. Thanks for the tip Sjoerd! [Source: Autogespot via Autoblog.nl ] More Photos
