# 2009-2012 BMW Z4 sDrive23i The E89-generation BMW Z4 sDrive23i represents the more accessible entry point to BMW's roadster lineup, powered by a 2.5-liter inline-six producing around 204 horsepower. This iteration marked a controversial shift from the previous Z4's quirky styling to a more aggressive, conventionally handsome design with a retractable hardtop replacing the fabric roof. Reviewers praised its balanced chassis and engaging dynamics, though the 23i lacked the punch of six-cylinder variants. The hardtop added refinement but also weight. It's famous for offering genuine BMW driving pleasure at a lower price point, though criticized for cramped interior space and limited practicality. Today, it suits weekend enthusiasts seeking an affordable, comfortable convertible with sporting pretensions—ideal for fair-weather driving rather than track days or daily commuting.
The Z4 sDrive23i features BMW's naturally-aspirated N52 inline-6 engine, known for relatively good reliability compared to turbocharged BMWs. However, expect premium costs for routine maintenance, parts, and labor at BMW specialists. Common issues include water pump failures, valve cover gasket leaks, and electronic gremlins. Insurance rates run moderately high due to sporty classification.
