That 3-series model and this Z4 are powered by an uprated and upgraded version of the sweet N54 3.0-liter twin-turbocharged inline-six. It’s no coincidence that BMW announced its new 335is in the same time frame as it did the Z4 sDrive35is. So what’s up with this sDrive35is model? It’s ostensibly the Z4 for those who want an Ultimate Driving Machine, so why throw more thrust-35 hp in this case-at a car that already has plenty and not fix the disappointing chassis? To charge more, of course, for what amounts to little more than some standardized options and what an aftermarket tuner could do with an ECU reflash. The clues are there in the folding hardtop, the electric hand brake, the light steering, and so on-the Z4 isn’t aimed toward enthusiast drivers. Given the brilliance of nearly every other BMW, the unfocused handling of what should be one of the company’s sportiest cars is even more of a bummer. BMW has long made machines that embody its “Ultimate Driving Machine” motto, but some of its more recent products have been more emblematic of the company’s other, softer, and less focused tagline, “Joy.” For example, instead of a thrilling, satisfying roadster, the Z4 is a boulevardier more likely to be parked among a sea of beige luxury SUVs at the country club than spotted hustling over mountain passes.
