The BMW Z4 is more than just a convertible—it’s a symbol of driving freedom, precision engineering, and sporty luxury. Whether you’re considering buying one, already own one, or just want to learn more, this guide gives you a full breakdown of the Z4’s history, specs, features, common issues, and what makes it special.
What Is the BMW Z4?
The BMW Z4 is a two-seater rear-wheel-drive sports car available as a soft-top convertible or coupe-style roadster. It belongs to BMW’s Z (Zukunft, or “future” in German) lineup and is known for its balanced handling, performance engines, and classic long-hood/short-rear design.
The Z4 blends daily comfort with weekend thrills, appealing to drivers who want a stylish yet capable performance car.
BMW Z4 Generations Overview
The BMW Z4 has gone through three main generations since its debut in 2002. Here’s a quick breakdown:
| Generation | Model Code | Production Years | Body Style |
|---|---|---|---|
| 1st Gen | E85/E86 | 2002–2008 | Roadster (E85) / Coupe (E86) |
| 2nd Gen | E89 | 2009–2016 | Hardtop Convertible |
| 3rd Gen | G29 | 2018–Present | Soft-Top Roadster |
First Generation (E85/E86)
The first-gen Z4 replaced the BMW Z3. It featured a bold design with a long hood and short rear deck. Highlights included:
- Engines ranging from 2.5L inline-6 to 3.2L in the M version
- Manual and automatic transmissions
- Z4 M Coupe and Roadster (E86/E85) with 330 hp S54 engine
Second Generation (E89)
This version introduced a folding hardtop, making it both a coupe and a convertible. Features included:
- Turbocharged 4- and 6-cylinder engines
- Comfort-focused ride with optional adaptive suspension
- No M model but a top trim “35is” with 335 hp
Third Generation (G29)
The latest Z4 returns to a classic soft-top design and offers modern tech and performance:
- Shared platform with the Toyota Supra
- Turbocharged 2.0L and 3.0L engines
- Available M40i with 382 hp and 0–60 mph in ~4.0 seconds
- iDrive 7, digital gauges, and driver assistance options
BMW Z4 Performance and Trims
The Z4 balances spirited driving with luxury features, especially in its M Performance versions. Here’s what to expect:
Current G29 Trim Levels (2023–2025)
- Z4 sDrive30i – 2.0L turbocharged 4-cylinder, 255 hp
- Z4 M40i – 3.0L turbocharged inline-6, 382 hp
All versions come with rear-wheel drive and an 8-speed automatic transmission. While manual options were absent, BMW recently confirmed the M40i will be offered with a manual gearbox in select markets.
Interior and Comfort
The Z4’s cabin combines high-end materials, digital displays, and driver-focused ergonomics.
- Heated seats, dual-zone climate, and premium sound standard or optional
- Soft-close roof operates in about 10 seconds
- Decent trunk space for a roadster (around 9.9 cubic feet)
It’s surprisingly practical for a weekend sports car.
BMW Z4 Reliability and Common Issues
Overall, the Z4 is a reliable model, but there are known issues in earlier generations.
Common Problems by Generation:
- E85/E86: Sticky steering, rear coil spring failure, hydraulic roof problems
- E89: Roof mechanism wear, electronic water pump issues, HPFP on early turbo engines
- G29: Few widespread problems; occasional sensor errors or infotainment glitches
Routine maintenance and inspections, especially of the cooling system and roof mechanism, can keep the Z4 trouble-free for years.
Who Should Buy a BMW Z4?
The BMW Z4 is perfect for drivers who want:
- A stylish weekend roadster with real performance
- Open-top driving without sacrificing comfort
- Luxury features in a small, rear-wheel-drive package
It’s not a daily hauler or family car, but it delivers an emotional and satisfying drive every time you hit the road.
BMW Z4 vs Toyota Supra
Since the G29 Z4 shares a platform with the Toyota GR Supra, many ask: which one’s better?
While both use the same BMW engines and architecture, here’s how they differ:
| Feature | BMW Z4 | Toyota Supra |
|---|---|---|
| Body | Convertible | Coupe |
| Interior | Premium-focused | Sporty, minimalist |
| Transmission | Auto only (manual coming) | Auto and 6-speed manual |
| Ride Comfort | Smoother | More aggressive |
Choose the Z4 if you want luxury and top-down freedom. Pick the Supra for a coupe experience with tighter dynamics.
