Z4 sDrive35is - Car and Driver
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. 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. 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. It’s no coincidence that BMW announced its new 335is in the same time frame as it did the Z4 sDrive35is. The N54 was good for 300 hp and 300 lb-ft in its previous, more ordinary applications, but all the “aye ess” cars receive software that cranks up the turbo boost, for a total output in the Z4 of 335 hp at 5900 rpm and 332 lb-ft of torque from 1500... Mash your right foot to the floor, and a computer-controlled overboost function will provide a seven-second gust of 37 additional lb-ft of torque. If the engine computer is satisfied with turbo temperatures and other vital signs, the incremental torque boost can be accessed over and over again under wide-open throttle.
