Best BMW Z4 Model Years (Ranked) in 2027

1. 2019-2024 G29 sDrive M40i

The 2019-2024 G29 sDrive M40i ranks first because it combines the robust B58 3.0L turbocharged inline-six with 382 horsepower and the strongest reliability record in Z4 history. It accelerates to 60 mph in about 3.9 seconds via an eight-speed automatic and an electronically locking differential. The chassis is stiffer and the adaptive suspension delivers a refined yet engaging ride. This generation also features current iDrive technology and a more durable overall package.

This is the Z4 for buyers who want the best blend of modern speed, comfort, and dependability without classic-car compromises. It trades away the raw analog feel of earlier models for a more polished daily driver. Compared to the lower-ranked sDrive30i, the M40i offers significantly more power and the celebrated B58 engine. A recent used example is the smartest choice for a primary or weekend roadster.

2. 2009-2011 E89 sDrive30i

The 2009-2011 E89 sDrive30i ranks second as the best value pick because it offers a retractable hardtop and a smooth naturally aspirated 3.0L inline-six with 255 horsepower. This engine avoids the higher maintenance demands of the twin-turbo N54 found in the sDrive35i. The hardtop provides security and refinement that soft-top rivals cannot match, making it a versatile daily roadster. Its used price sits well below comparable Porsche and Mercedes models.

This Z4 is for value-focused buyers who want classic inline-six character and hardtop convenience at a low entry cost. It trades away the modern technology and reliability of the newer G29 for a more analog experience. Compared to the top-ranked M40i, it is slower and less refined but far more affordable to purchase. A well-maintained example delivers rewarding open-top driving without the newest-car premium.

3. 2019-2024 G29 sDrive30i

The 2019-2024 G29 sDrive30i ranks third because it delivers most of the newest Z4's appeal with a dependable B48 2.0L turbocharged four-cylinder producing 255 horsepower. It reaches 60 mph in about 5.2 seconds, offering brisk performance with notably better fuel economy than the M40i. The modern chassis, adaptive suspension options, and current infotainment system are shared with the top-ranked model. The B48 has a far better track record than the earlier N20 engine it replaced.

This is the Z4 for buyers who want the latest design and technology without paying inline-six money. It trades away the M40i's power and engine character for lower running costs and a cheaper purchase price. Compared to the second-ranked E89 sDrive30i, it offers superior reliability and modern features but lacks the retractable hardtop. A clean sDrive30i is a smart, lower-cost entry into the newest generation.

4. 2012-2016 E89 sDrive35i

The 2012-2016 E89 sDrive35i ranks fourth because it pairs the refined N55 single-turbo 3.0L inline-six with 300 horsepower and the signature retractable hardtop. This engine is a more robust and smoother turbo than the older N54, offering strong performance and daily usability. The refreshed E89 also brought updated styling and an eight-speed automatic option. The hardtop remains a standout feature for security and coupe-like refinement.

This Z4 is for buyers who want modern turbo power with hardtop convenience and a more dependable engine than the earlier 35i. It trades away the raw character of the N52 naturally aspirated six for more torque and efficiency. Compared to the third-ranked sDrive30i, it is older but offers a more engaging inline-six and a folding hardtop. A documented sDrive35i is a rewarding used roadster, though the N20 four-cylinder in the sDrive28i should be avoided.

5. 2006-2008 E85/E86 3.0si

The 2006-2008 E85/E86 3.0si ranks fifth because it features the excellent N52 3.0L inline-six with 255 horsepower, praised for its smoothness and strong power delivery. This first-generation Z4 offers sharp, communicative handling and classic long-hood proportions that many enthusiasts prefer. The roadster and especially the rare E86 coupe deliver a pure, analog driving feel. It is a charismatic choice with a proven engine architecture.

This Z4 is for enthusiasts who value direct steering and a raw connection to the road over modern technology. It trades away the retractable hardtop and current infotainment for a lighter, more engaging experience. Compared to the fourth-ranked E89 sDrive35i, it is less powerful but more affordable and more rewarding to drive. A well-kept 3.0si, particularly the coupe, is a smart buy for those seeking classic roadster character.

6. 2006-2008 Z4 M Roadster

The 2006-2008 Z4 M ranks sixth because it is the halo car, fitting the high-revving S54 3.2L inline-six from the E46 M3 with around 330 horsepower and a six-speed manual. It is raw, fast, and hugely engaging, with the M Coupe becoming a collectible with rising values. This is the most thrilling and special Z4 ever produced, offering motorsport-derived performance. Its dynamics are unmatched by any other model year.

This Z4 is for dedicated enthusiasts who want the ultimate driving experience and are prepared for its upkeep. It trades away daily comfort and modern reliability for a pure, demanding sports car character. Compared to the fifth-ranked 3.0si, it is significantly faster and more special but requires diligent maintenance. Buy only with documentation of rod-bearing inspection and VANOS service to avoid expensive repairs.

7. 2003-2005 E85 3.0i

The 2003-2005 E85 3.0i ranks seventh because it launched the Z4 with the durable M54 3.0L inline-six producing 225 horsepower. It offers a slick six-speed manual and a stiffer body than the Z3 it replaced, with classic roadster styling. The M54 is a well-understood engine with a strong reputation for longevity. Pricing is low, making it an affordable entry into open-top inline-six motoring.

This Z4 is for budget buyers who value mechanical simplicity and proven durability over modern features. It trades away the sharper handling of later models and the power of the 3.0si for a lower purchase price. Compared to the sixth-ranked Z4 M, it is far less performance-oriented but much cheaper to maintain. A clean 2003-2005 3.0i is a sensible choice for those wanting a classic BMW roadster experience.

8. 2003-2005 E85 2.5i

The 2003-2005 E85 2.5i ranks eighth because it offers the same handsome roadster styling and rear-drive balance as the 3.0i with a smaller 2.5L M54 inline-six around 184 horsepower. It is slower but still smooth and engaging, with the six-cylinder character being a highlight at this price point. The engine shares the durable M54 architecture of its larger sibling. It provides a lower running cost for entry-level buyers.

This Z4 is for budget-conscious buyers who want inline-six smoothness and classic Z4 looks without paying for the bigger engine. It trades away performance and some equipment for a more affordable purchase and running cost. Compared to the seventh-ranked 3.0i, it is noticeably slower, and the 3.0i is worth the small premium when available. A well-maintained 2.5i is a sensible, affordable open-top choice for those new to the model.

9. 2009-2016 E89 sDrive35is

The 2009-2016 E89 sDrive35is ranks ninth because it is the performance flagship of the hardtop generation, with a tuned twin-turbo 3.0L N54 producing about 335 horsepower and an overboost function. It pairs with a seven-speed dual-clutch transmission, making it the quickest pre-G29 Z4. Upgraded cooling and sharper styling cues set it apart from the standard 35i. It delivers genuine sports-car pace under the retractable hardtop.

This Z4 is for enthusiasts who want the most powerful folding-hardtop model and accept the N54's higher maintenance burden. It trades away the reliability of the N55 for more power and a more aggressive character. Compared to the eighth-ranked 2.5i, it is vastly faster but far more expensive to service. Buy one only with documented repairs to the high-pressure fuel pump, injectors, and wastegates.

10. 2012-2016 E89 sDrive28i

The 2012-2016 E89 sDrive28i ranks tenth because it brings the N20 2.0L turbocharged four-cylinder with 240 horsepower, offering good performance and better fuel economy than the sixes. It is capable and enjoyable when healthy, with strong mid-range torque and the convenience of the retractable hardtop. The engine provides a modern, efficient driving experience. It is the most affordable way into the refreshed E89 generation.

This Z4 is for buyers who prioritize fuel economy and a lower purchase price over long-term reliability. It trades away the smoothness and durability of the inline-six engines for a lighter, more efficient turbo four. Compared to the ninth-ranked sDrive35is, it is far less powerful but also less demanding to run. Only buy one with documentation that the timing chain was inspected or replaced to avoid expensive repairs.

How we ranked these

This ranking weighs reliability, driving character, performance, and value across all Z4 generations. Primary factors include engine durability (B58 vs. N20/N54), chassis dynamics, feature content, and typical used-market pricing. Data from owner reports, expert reviews, and recall databases informed scores, with the G29 M40i earning top marks for its robust B58 and modern refinement.

Deliberately ignored were subjective styling preferences, brand loyalty, and aftermarket potential. Also excluded were extreme low-mileage collector values and track-day performance, as these do not reflect the priorities of a typical used roadster buyer. The focus remains on real-world ownership costs and daily usability, ensuring the ranking serves practical purchasing decisions.

What to look for

When choosing a used Z4, prioritize the engine over the model year. The B58 in the G29 and the N52 in the E85/E86 are the most reliable, while the N20 and N54 require careful history checks. Verify timing chain service on N20s and fuel pump/injector health on N54s. A documented maintenance record is worth more than a lower price.

The most common mistake is buying on price alone without inspecting engine-specific failure points. Many buyers overlook the N20's timing chain or the N54's high-pressure fuel pump, leading to costly repairs. Always run a VIN check for recalls and insist on a pre-purchase inspection by a BMW specialist to avoid a money pit.
