The Z4 is not at all impressive. The 3 litre puts out 220 HP. The 2.5 litre puts out 183 HP. Unless the car is a Z4 Alpina V8 it aint got nothing for the Z28. The Z4 Alpina will be about even with an LT1 car a little less than a match for an LS1.

My response:
I agree they are both weak offerings from both companies and would benefit from stronger motors the z4 3.0 liter inline 6 puts down 225hp and 214lb ft. of torque and there is no alpina version of it - good luck fitting a 4.6 liter V8 in that engine bay--Only the z8 has the alpina package which has a smaller V8 (hence not the 5.0 in the regular z8 because the auto transmission thats in the Alpina cant withstand that much power.) so get it straight
