# 2009-2016 BMW Z4 sDrive35i The second-generation Z4 sDrive35i is BMW's turbocharged roadster powered by a potent 3.0-liter inline-six producing 300-335 horsepower (depending on year). Unlike its predecessor, it features a power-retractable hardtop, transforming from convertible to coupe in 20 seconds. Reviewers praise its muscular acceleration, precise steering, and luxurious interior, though some criticize the numb electric power steering and firm ride. The styling—penned by designer Juliane Blasi—proved polarizing with its aggressive lines and flame-surfacing design language. It's famous for its thrilling twin-turbo power delivery and being one of the last purely driver-focused BMW roadsters before the brand's shift toward technology and comfort. **Best for:** Enthusiasts seeking weekend back-road thrills and open-air driving with German refinement. The hardtop makes it more practical year-round than soft-top competitors, ideal for secondary-car duty.
The Z4 sDrive35i's N54 twin-turbo engine requires premium fuel and expensive maintenance. Common issues include high-pressure fuel pump failures ($1,000+), wastegate rattle, and water pump replacements. Turbos may need replacement around 100k miles ($3,000-5,000). Insurance runs high due to performance classification. Expect significantly above-average operating costs typical of BMW sports cars.
