BMW Z4

BMW has axed the BMW Z4 M because according to them, there is no business case in such a product in this time and age, thanks to the economic downturn and the lack of interest in such a model.

Yes, yes, I know, no business case for the Z4 M but no problem for the X5 M and the X6 M, hardcore versions of now-frowned-upon SUVs? Well, think of it this way, with some of the rich losing alot of their investment values in the crash, most can no longer afford a big SUV for the weekdays and a sports car for the weekends. They will have to buy a 2 in 1 vehicle, something that serves both functions. Oh my, how tragic!!!

The reality is that these products begin development long before we even hear of them and the X5 M and the X6 M had been signed off long before all of this mess happened, which is why BMW is going ahead with them anyway.

The top of the line Z4 is going to be a M-Sport Z4 which has yet to be revealed, and will get the usual wheels, bodykit, suspension, steering and etc. It may even get BMW Performance parts thrown into the mix, either as standard or as an option. The flagship Z4 is the xDrive35i and BMW Performance could make available a BMW Performance Power Kit for the Z4, similiar to the kit they did for the same twin turbo engine in the 335i and the 135i. It upgrades the engine’s power from 306hp and 400Nm up to 326hp and 450Nm, equalling the tuning found in the BMW 740i. As it is, that’s more torque than the new M3 by a good 50Nm, and spread wide across the RPM range too.

Coupled with the recent announcement that the next gen M3 and M5 will go small-engine with twin-turbo power instead, it looks like the delicious high-revving S65B40 4.0 litre V8 will not find its way into any other production BMW other than the M3 :(

As a tribute to the S65B40, there are 2 orgasmic sound files after the jump of the engine being worked hard on the dyno and on the track as well. Enjoy!
