In a progress move that continues to shape the sports-car landscape, BMW’s engineering push for the current Toyota Supra was carried out in close parallel with the G29 Z4. The result is a pair of cars sharing a foundational DNA while delivering distinct driving personalities. The Z4 stands out as the more thrilling option on open roads, especially with its canvas electric roof lowered to let the engine’s voice fill the cabin.
The cockpit remains a defining trait. Some drivers love the seating position,while others might not,as it places you close to the rear axle with the bonnet stretching ahead. Yet the manual gearbox earns praise for its precision, and the six-cylinder engine responds with a crisp surge and a torque-rich mid-range. Acceleration is brisk, clocking 0-62 mph in about 4.6 seconds and delivering a compelling mid-range shove that keeps the driving experience lively.
When driven with the heart first, the Z4 offers a pure, engaging experience. on the right road, it’s utterly delightful; in dense, rain-soaked traffic, its charm can soften, but it remains one of BMW’s most memorable cars of the past three decades and is highly likely to be missed by enthusiasts.

Why the Manual Transmission Still Matters
- Driver Engagement – A true clutch‑pedal feel connects the driver to the engine’s surge, something a dual‑clutch cannot replicate.
- Linear Power delivery – the B58’s torque curve stays flat down to 1,550 rpm, allowing effortless downshifts and rapid acceleration out of corners.
- Track‑Day Advantage – Short‑ratio 6‑speed manuals let skilled drivers keep the revs in the sweet spot, shaving up to 0.2 seconds off a lap compared with the automatic.
Performance Face‑off: BMW Z4 M40i manual vs. Toyota GR Supra (2025)
| Category | BMW Z4 M40i Manual | Toyota GR supra (2.0L Turbo) |
|---|---|---|
| power | 382 hp | 382 hp (A91) |
| Torque | 368 lb‑ft | 368 lb‑ft |
| Transmission | 6‑speed manual | 8‑speed automatic |
| 0‑60 mph | 4.3 s | 4.1 s (auto) |
| Lateral G (slalom) | 0.93 g | 0.89 g |
| Weight | 3,380 lb | 3,450 lb |
| Center of Gravity | 14.3 in (front) | 15.0 in (front) |
| Price | $60,850 | $56,900 |
Key Takeaways
- Power parity is offset by the Z4’s lighter chassis and lower center of gravity, delivering sharper handling.
- Manual vs. automatic: While the Supra’s auto is marginally quicker in a straight line, the Z4’s manual offers a more rewarding corner‑exit.
- pricing: The Z4’s premium interior and convertible roof add modest cost, but the value proposition remains strong for enthusiasts seeking an open‑air experience.
Chassis & Suspension: The Z4’s Road‑Holding DNA
- Multi‑Link Rear Suspension – Provides self-reliant wheel control, reducing squat under hard acceleration.
- Adaptive M‑Damping – Six‑stage system automatically adjusts rebound and compression rates, yet retains a “Sport” mode that locks in a firmer setting for track days.
- Carbon‑Fiber Reinforced Plastic (CFRP) Roof – Adds rigidity while keeping weight down, improving torsional stiffness by 12 % over the previous generation.
- Steering Ratio – Swift‑ratio rack‑and‑pinion delivers 2.7 turns lock‑to‑lock, ideal for rapid direction changes on winding roads.
Engine & Transmission: Technical Deep‑Dive
- B58 Twin‑Turbo Block – Aluminum construction, lightweight pistons, and a closed‑deck design boost durability at high boost levels.
- Valvetronic Variable Valve Lift – Eliminates the need for a traditional throttle plate, smoothing throttle response and improving fuel efficiency (up to 28 mpg combined).
- 6‑Speed Manual Gearset – Short‑ratio first gear (2.92:1) and close‑spaced top gears keep the engine in its torque band during spirited driving.
- Clutch – Performance‑type single‑disc, 300 mm diameter, with a pneumatic assist for smoother launches.
Real‑World Test Data: Track Day Results
| Event | Driver | Lap Time (Mile) | Notes |
|---|---|---|---|
| Nürburgring Nordschleife (Full lap) | Marco Müller (BMW Motorsport) | 8:24.5 (manual) | Compared to 8:22.9 in the Z4 auto; 0.3 s difference reflects driver’s ability to stay in peak torque band. |
| Laguna Seca, Turn 8 | Sarah K. (Road & Track) | 36.1 s | Manual allowed earlier downshifts, maintaining momentum through the “Corkscrew.” |
| Local 2‑Mile Road Course | Tom Evans (AutoWeek) | 1:07.8 | Consistent lap times across three runs, demonstrating the gearbox’s reliability under repeated high‑load shifts. |
Owner Experience: What Enthusiasts Are Saying
- “Best Manual I’ve Owned” – A 2024 Z4 owner on the BMW M Club forum praised the clutch bite point as “predictable, yet responsive,” especially on hill climbs.
- Convertible Comfort – Reviewers note that the fabric‑wrapped roof retracts in 12 seconds, and the cabin remains quiet at 65 mph, a rarity for roadsters in this segment.
- Resale Value – Kelley Blue Book projects a 5‑year resale retention of 61 %, higher than the Supra’s 55 % due to limited manual availability.
Practical Buying tips for the Manual Z4
- Verify Manual Availability – As of 2025, the manual is offered only on the M40i trim; higher‑spec GTS and M versions remain automatic‑only.
- Consider the M Sport Package – Adds carbon‑fiber front splitter,sport seats,and upgraded brakes (380 mm front discs) for an extra $3,200.
- Test the Clutch – During a test drive, simulate city traffic stop‑and‑go to assess pedal feel and fatigue.
- Check the Roof Mechanism – Operate the soft‑top repeatedly to ensure smooth deployment; a common issue in early 2023 units was a delayed latch.
- Insure for Convertibles – Expect a 12‑15 % premium increase over coupe rates; factor this into total cost of ownership.
Maintenance & Ownership Costs
- Scheduled Service – BMW’s “Ultimate Care” plan (3 years/36,000 mi) covers oil changes, brake fluid, and filter replacements; estimated at $650 per service.
- Clutch Longevity – With normal street driving, the clutch typically lasts 80,000-100,000 mi; aggressive track use may reduce this to 40,000 mi.
- Tire Wear – The Z4’s wider rear (225/45R18) tire tends to wear faster; a set of high‑performance summer tires averages 15,000 mi before replacement.
- Fuel Cost – At an average of 28 mpg combined and a US average price of $3.80/gal, yearly fuel expense for 12,000 mi is roughly $1,630.
Benefits of Choosing the Z4 Over the Supra
- Open‑Air Experience – true convertible roof vs. Supra’s fixed coupe silhouette.
- Manual Purity – Z4 remains one of the few modern roadsters offering a six‑speed manual, satisfying purist drivers.
- Luxury Interior – Premium leather,ambient lighting,and the newest iDrive 9 system with over‑the-air updates.
- Brand Heritage – BMW’s decades‑long roadster lineage (Z8, Z4, M Roadster) adds a cultural cachet that resonates with collectors.
