As the automotive industry pivots aggressively toward electrification, traditional internal combustion roadsters are becoming increasingly rare. The second-generation BMW Z4 (E89), produced between 2009 and 2016, stands as a notable example of this era. While BMW has since returned to soft-top designs for its convertibles, the Mk2 Z4 remains a compelling option for enthusiasts seeking a blend of premium refinement and spirited driving.
The Z4 Philosophy: Cruiser vs. Sports Car
BMW has long been a leader in producing “driver’s cars,” but there is a subtle distinction in their lineup. While models like the M3 focus on raw performance, the Z4 was designed as a premium cruiser.
Unlike its predecessor, the Z3, or its more aggressive rivals like the Porsche Boxster, the Z4 Mk2 prioritized comfort and usability. This was achieved through its signature coupé-cabriolet design—a folding metal roof that offers better insulation and security than a fabric top, though at the cost of significant weight and reduced boot space.
Model Evolution and Engine Options
The Z4 lineup underwent several changes during its seven-year run:
- The Early Years (2009–2012): The range was defined by smooth six-cylinder engines, including the 2.5L sDrive23i, the 3.0L sDrive30i, and the high-performance 3.0L sDrive35i. The flagship sDrive35is arrived in 2010, delivering a potent 340bhp.
- The Four-Cylinder Era (2012–Present): To appeal to a wider market, BMW introduced turbocharged 2.0-litre four-cylinder engines (sDrive20i and sDrive28i). These offered a more efficient, daily-driver experience.
- The Facelift (2013): A mid-cycle refresh updated the aesthetics with new headlights and color options, while also introducing the entry-level sDrive18i.
Which Model Should You Buy?
Choosing the right Z4 depends on your priority: emotion or economy.
- For the Enthusiast: The six-cylinder models (sDrive30i and above) are highly recommended. They provide a superior engine soundtrack and much more effortless acceleration.
- For the Daily Driver: The four-cylinder models (sDrive20i/28i) offer much more reasonable running costs and fuel economy without sacrificing much in terms of “fun factor.”
- Trim Levels:
- Standard: Comes well-equipped with dual-zone climate control and xenon headlights.
- M Sport: Adds stiffer suspension, 18-inch alloys, a body kit, and sports seats. Note: The M Sport ride can feel quite firm on uneven roads.
Practicality and Interior
The Z4 is a dedicated two-seater, which means the cabin feels snug and high-quality. Even taller drivers generally find it comfortable, thanks to the supportive seating. However, the metal roof imposes a heavy penalty on practicality:
* Boot Space (Roof Up): 310 litres.
* Boot Space (Roof Down): 180 litres (smaller than a standard hatchback like a Kia Picanto).
The interior remains “old-school” by modern standards—featuring physical buttons and analog gauges rather than massive digital screens—but many drivers find this layout more intuitive and less distracting during spirited drives.
Buyer’s Checklist: What to Watch For
If you are inspecting a used Z4, pay close attention to these specific areas:
- The Roof Mechanism: While generally reliable, check for hydraulic fluid leaks. A leak can stain the interior and cause the roof to jam.
- Wheels and Tyres: The standard run-flat tyres can make the ride feel harsh. Many owners switch to standard tyres for better comfort. Additionally, the 19-inch alloy wheels are prone to cracking when hitting potholes.
- Engine Health: On high-mileage cars, check for faulty fuel injectors, which can cause the engine to run unevenly or cut out.
- Common Wear: Look for water ingress in the rear light clusters and ensure the side windows operate correctly when the roof is in motion.
Market Alternatives
If the Z4 doesn’t quite fit your needs, consider these rivals:
* Porsche Boxster/Cayman: The gold standard for pure, engaging handling.
* Mercedes-Benz SLK/SLC: Offers excellent build quality and a smoother, more relaxed ride.
* Audi TT: A highly polished option that uniquely offers four-wheel drive.
* Mazda MX-5: Lighter and more “tossable,” though less sophisticated and premium than the BMW.
Summary: The BMW Z4 Mk2 is a sophisticated, well-built roadster that excels as a premium cruiser. While it lacks the razor-sharp agility of a Porsche, its refined cabin and balanced driving dynamics make it an excellent choice for those seeking a stylish, high-quality weekend companion.
