# 2013-2016 BMW Z4 sDrive35is The Z4 sDrive35is represents the high-performance variant of BMW's second-generation roadster, featuring a turbocharged 3.0-liter inline-six producing 335 horsepower and 332 lb-ft of torque. With a 0-60 mph time around 4.6 seconds, it offered exhilarating straight-line performance. Reviewers praised its potent engine and sharp handling but criticized the firm ride and limited cargo space. The retractable hardtop provided year-round versatility unusual for roadsters. Enthusiasts note its relative rarity and appreciate the tunability of the N54 engine. The Z4 is somewhat infamous for expensive maintenance and potential turbo/fuel injector issues typical of N54 engines. Today, it suits driving enthusiasts seeking an engaging, powerful convertible for weekend drives and backroad carving—not ideal for daily commuting or practicality-focused buyers.
The Z4 sDrive35is features BMW's N54 twin-turbo engine, known for failing high-pressure fuel pumps, wastegate rattles, and carbon buildup requiring walnut blasting ($500+). Expect expensive maintenance: premium fuel required, pricey BMW parts, and costly repairs. However, it's generally more reliable than perceived, with fewer electrical issues than other BMWs. Insurance runs high due to performance classification.
