History of the BMW Z4

The Z4 roadster has been an integral part of BMW’s model line-up since 2002. Here’s a look at the evolution of the Z4 over the years:

E85 Generation (2002-2008) – The first-generation Z4 (E85) debuted in 2002 and was designed by Danish BMW designer Anders Warming. It featured classic roadster styling with a soft convertible top and minimal overhangs. Engine options ranged from 2.5L to 3.0L producing 184hp to 255hp. The E85 Z4 found success in motorsports and was used as the pace car in the 2006 Indy 500.
E89 Generation (2009-2016) – The second-gen E89 Z4 was introduced in 2009 featuring a retractable hardtop, the first for a BMW roadster. The design was more aggressive and masculine than the previous generation. Engine choices included an inline-6 3.0L, producing 306hp in the top Z4 sDrive35is model. A 6-speed manual was available, along with a 7-speed dual-clutch transmission.
G29 Generation (2018-Present) – After a two year hiatus, BMW released the third-gen G29 Z4 in 2018 – returning to the soft-top convertible styling. Co-developed with Toyota, the new Z4 shared the same platform and assembly line as the new Toyota Supra sports car. The G29 Z4 launched with two engine options: a 2.0L turbo 4-cylinder and 3.0L turbo inline-6. Power ranges from 255hp to 382hp depending on the engine and trim.

BMW Z4 Generations and Models Over the Years

Let’s take a more detailed look at the different BMW Z4 model generations and key variants over the sports car’s 20+ year history:

E85 Z4 Models (2002-2008)

The first-generation E85 Z4 had a production run from 2002 to 2008. Here are some notable versions:

Z4 2.5i – The base Z4 roadster launched in 2002 with a 2.5L inline-6 engine producing 184hp. It came standard with a 5-speed manual and had a 0-60mph time of 6.7 seconds.
Z4 3.0i – Introduced in 2003, the 3.0i model had a more powerful 3.0L inline-6 engine producing 225hp. It lowered the 0-60mph acceleration time to 5.8 seconds.
Z4 M Roadster – BMW’s in-house M performance division released the Z4 M in 2006 with a specially tuned 3.2L inline-6 pumping out 340hp. With a 0-60mph sprint of only 4.8 seconds, the M Roadster cemented itself as a truly thrilling performance machine.
Z4 Coupé – Also debuting in 2006, the Z4 Coupé featured a fixed metal roof and different rear styling. However, it retained the same engine options as the roadster.

E89 Z4 Models (2009-2016)

The second-generation E89 Z4 spanned from 2009 to 2016. Here are some key E89 models:

Z4 sDrive35i – At launch in 2009, the top-spec Z4 35i used a 3.0L turbo inline-6 with 306hp and 295 lb-ft torque, delivered through a 7-speed DCT. It reached 60mph in 4.8 seconds.
Z4 sDrive35is – This Performance Package trim added an overboost function to increase torque to 332lb-ft and decrease 0-60mph acceleration to just 4.7 seconds.
Z4 sDrive28i – The 28i arrived in 2012 with BMW’s new 2.0L turbo 4-cylinder engine and 240hp. Available with a manual or automatic, the 28i was praised for its nimble handling.
Z4 E89 LCI – The mid-cycle LCI (Life Cycle Impulse) refresh in 2014 brought design tweaks, upgraded iDrive, and new engine options.

G29 Z4 Models (2018-Present)

The third-generation G29 Z4 first hit the market in 2018:

Z4 sDrive30i – The latest sDrive30i launched in 2018 with a 2.0L turbo-4 engine and 255hp. With the M Sport package, it achieves the 0-60mph sprint in 4.4 seconds.
Z4 M40i – Topping the range is the M40i and its 3.0L turbo inline-6 pumping out 382hp. It rockets to 60mph in just 3.9 seconds.
Z4 sDrive20i – In some markets, BMW also offers the sDrive20i model and its 4-cylinder 197hp engine.

Z4 Performance, Engines, and Transmissions

As you can see from the model generations above, BMW has equipped the Z4 roadster with a wide range of engine and transmission options over the years. Here’s an overview:

Inline-6 Engines – Naturally aspirated inline-6 engines powered the first Z4 models. Displacements ranged from 2.5L to 3.2L, producing between 184hp to 340hp. The silky smooth inline-6 delivers perfect front-rear balance.
Turbocharged 4 and 6-Cylinders – Beginning with the E89 generation in 2009, BMW added turbocharged engines to boost power outputs. Today’s Z4 uses a 2.0L turbo-4 or 3.0L turbo inline-6, each with different power levels depending on the exact trim.
8-Speed Automatic – Most recent Z4 models come equipped with a quick-shifting 8-speed automatic transmission. It delivers sporty performance and improved fuel efficiency.
6-Speed Manual – Purist drivers rejoice – a 6-speed manual gearbox is still available as an option on select Z4 trims. The manual provides an engaging drive experience.
Dual Clutch Transmission – Some higher performing Z4 models use BMW’s 7-speed dual-clutch (DCT) transmission, providing extremely fast shift speeds.

No matter which engine and transmission combination, the Z4 provides exhilarating acceleration backed by BMW’s reputation for world-class powertrains. Make sure to test drive the different options to see which suits your style best.

BMW Z4 Handling, Steering, Suspension and Driving Dynamics

Beyond raw engine power, the BMW Z4 also excels when it comes to overall driving dynamics and handling capabilities:

Near 50/50 Weight Distribution – By optimizing weight distribution between the front and rear axles, the Z4 achieves near-perfect balance for agile handling.
Front and Rear Suspension – Sophisticated suspension systems use double pivot strut and five-link architecture for precision control. Adaptive M options are available.
Electric Power Steering – Provides the Z4 with speed-sensitive power steering that firms up at higher speeds. Steering is precise and optimized for performance driving.
Limited Slip Differential – An electronically-controlled limited slip differential is equipped on higher trim models to improve traction by distributing power evenly to both rear wheels.
M Sport Package – The M Sport package adds performance upgrades like larger brakes, a lowered sport suspension, and bigger wheels with high-performance tires.

With its balanced chassis and sophisticated steering and suspension systems, the Z4 provides one of the most nimble and razor-sharp driving experiences in its class.

Key Interior and Exterior Z4 Features and Technologies

The BMW Z4 interior emphasizes both luxury and performance. Here are some of the key features:

Sport Seats – Supportive leather sport seats keep occupants firmly in place during aggressive corners. Power adjustability and heating functions available.
Cockpit Design – Angled towards the driver, the cockpit has easy-to-read gauges and BMW’s latest technology displays.
iDrive System – The Z4 gets BMW’s intuitive iDrive control system with a center display for navigation, entertainment, vehicle settings, and more.
Harman Kardon Sound – An available Harman Kardon surround sound system with 12 high-fidelity speakers provides a concert-like audio experience.
Adaptive Cruise Control – Radar-based cruise control automatically maintains a set distance from the car in front, even braking and accelerating as needed in traffic.

Exterior Z4 highlights include:

Soft Top Convertible – A high-quality soft top folds away to allow open-air driving. The sleek top stores under a flush cover when stowed.
Sharp Styling – Long hood, short rear deck, minimal overhangs, and bulging fenders give the Z4 an aggressive sports car look.
Signature BMW Design – Iconic styling cues like the kidney grille, Hofmeister kink, and corona headlight rings tie the Z4 to its BMW heritage.
Aluminum Doors – Lightweight aluminum door skins shave weight for better handling and performance.
Wind Deflector – A wind deflector deploys behind the front seats to reduce interior turbulence when driving with the top down.

BMW Z4 Safety Ratings and Safety Features

For a compact sports car, the BMW Z4 still places a strong emphasis on safety:

5-Star Euro NCAP Rating – The latest Z4 earned the maximum 5-star safety rating from Euro NCAP testing. It scored highly for adult, child, pedestrian, and driver assist safety.
Stability Control – All Z4 models come standard with advanced stability control to prevent loss of traction and skidding during performance driving.
Run-Flat Tires – Run-flat tires allow continued driving even after a puncture. A reinforced sidewall provides up to 80 miles of range to get to a repair shop.
Front Airbags – Dual front airbags provide critical protection for the head and chest in the event of a collision.
Side Airbags – Side airbag curtain systems deploy from the headliner to cushion occupants in a side impact accident.

While a convertible will never offer the protection of a hardtop coupe or sedan, the Z4 still provides reasonable safety with its array of standard safety tech.

How Reliable Is the BMW Z4? Common Problems

The BMW Z4 has proven to be a fairly dependable sports car, but it’s not without some common issues:

Electrical Glitches – Various electrical gremlins like faulty switches, sensors, and indicator lights may arise. Diagnosing electrical issues can be tricky.
Oil Leaks – Leaking valve cover gaskets and oil filter housing are widespread on earlier 6-cylinder Z4 models. Oil leaks primarily just require resealing.
Water Leaks – Over time, dried and cracked rubber seals can allow rainwater to enter the cabin. Carefully inspecting and replacing aged seals prevents leaks.
Thermostat Failures – Failed thermostats are a known problem, causing improper engine temperature regulation and overheating in some cases.
Intermittent Loss of Power – Carbon buildup in the cylinders can occasionally trigger power losses when accelerating hard. Induction cleaning services may help.

Overall, the Z4 has proven to be a fairly reliable convertible sports car as long as scheduled maintenance is performed. The most common issues are minor leaks, electrical gremlins, and other small glitches typical of German luxury brands.

How Does the BMW Z4 Compare to the Competition?

The Z4 competes directly with luxury roadsters and coupes like the Porsche 718 Boxster/Cayman along with the Mercedes-Benz SLC-Class. Here is how the Z4 stacks up against key rivals:

Porsche 718 Boxster/Cayman – Porsche’s mid-engine sports cars are focused more on track performance than grand touring like the Z4. However, Porsche’s impeccable handling may make it more appealing for driving enthusiasts. Expect to pay more for a similarly equipped 718.

Mercedes-Benz SLC-Class – With a front-engine layout like the Z4, the Mercedes SLC provides a comparable overall experience. However, Mercedes doesn’t currently offer the multiple engine choices available on the Z4. The SLC-Class convertible tops out at 362hp from its V6.

Toyota Supra – Sharing the same platform and production line, the revived Toyota Supra has many similarities under the skin to the new Z4. The Supra is marketed more as an affordable sports car, starting under $50k. However, it lacks the premium interior and brand cachet of a BMW.

While the Porsche 718 and Mercedes SLC compete for the title of top luxury roadster, the Z4’s combination of performance, comfort, styling, and brand reputation give it a solid standing. The Supra appeals more to value-focused enthusiasts.

The Future: What’s Next for the BMW Z4?

The current third-generation Z4 just launched for 2019, so an all-new model is likely years away. However, here is what we may see down the road:

More Power – Look for more power to be extracted from BMW’s turbo engines, potentially boosting output over 400hp for the inline-6. Competition with higher-output rivals will push BMW to increase horsepower.
Hybrid Powertrains – To meet tightening emissions regulations, a plug-in hybrid Z4 could arrive that would allow driving on electric-only power for short distances. Combined with a combustion engine, power could be further increased.
Special Editions – BMW’s M performance division will almost certainly release more aggressive, limited-run Z4 M models. We also may see design collaborations like the recently revealed Z4 Orion Edition.
Self-Driving Tech – More advanced driver assistance systems could inch the Z4 towards semi-autonomous driving when cruising on highways. Expect driving aids to progress.

While new Z4 generations have historically arrived every 6-8 years, BMW will likely speed up the timeline as technology advances. The Z4 will continue pushing the limits of BMW performance and luxury.

Conclusion

The BMW Z4 remains an iconic luxury roadster combining performance, handling, and open-air freedom. By understanding the full picture of the Z4’s history, features, pricing, and competition, you can determine if this BMW is the right fit for your sports car needs. Make sure to take the Z4 on an extended test drive to truly experience the joy of driving one yourself. The Z4 manages to blend speed, thrills, comfort and elegant style into one stunning package.
