I head s2k's are faster and better??? correct me if im wrong...
I doubt it Z4 oWnS!!
Actually, a lot of people do feel that the S2000 out performs the Z4 with the 3.0 engine. I personally feel that the 3.0 Z4 is superior to the S2000, but thats just me.
The Z4's with the 2.5 engine are 184 HP, have a top speed of 146 mph, and weigh 3053 lbs. RWD and torque more than makes up for the weight, but you should still probably expect to see Celica GTS like performance from it in terms of accelleration.
Handling, on the other hand, is where the Z4 really shines. Its one of the best handling roadsters out there IMO.
