The Boxster S, a more powerful variant, accelerates from 0 to 60 mph in just 3.7 seconds, outpacing many competitors, including the BMW Z4 M40i.
Porsche’s decision to equip the 718 Boxster with a turbocharged flat-four engine marks a return to its roots, reminiscent of the 912 and 914 models from the late ’60s and early ’70s. This engine delivers a unique character that resonates with driving enthusiasts.

Comparaison des performances
Engine Power and Acceleration
When it comes to acceleration, both the Porsche Boxster and BMW Z4 M40i deliver thrilling experiences, but they do so in different ways. The BMW Z4 M40i, with its 3.0-liter straight-six engine, rockets from 0 to 60 mph in just 3.8 seconds. That’s blisteringly fast for a roadster! On the other hand, the Porsche 718 Boxster S, equipped with a turbocharged flat-four engine, achieves the same feat in 4.0 seconds. While the Z4 edges out in raw speed, the Boxster S offers a more engaging feel during acceleration, thanks to its mid-engine layout.
Here’s a quick comparison of their acceleration times:
Véhicule | Temps de 0 à 60 mph |
|---|---|
BMW Z4 M40i | 3.8 sec |
Porsche Boxster | 4.0 sec |
If you’re chasing pure speed, the Z4 might be your pick. But if you value a balanced and connected driving experience, the Boxster S has the edge.
Handling and Cornering Dynamics
Handling is where the Porsche 718 Boxster truly shines. Its mid-engine design provides near-perfect weight distribution, giving you exceptional traction and control. The steering feels smaller, more precise, and incredibly responsive. You’ll notice how easy it is to accelerate out of corners, making every twist and turn a joy.
The BMW Z4 M40i, while capable, doesn’t quite match the Boxster’s finesse. Its steering feels larger and less intuitive, requiring more effort to maintain control. Some drivers even describe the Z4’s handling as anxious, especially when applying throttle mid-corner. If you’re looking for responsive handling that feels effortless, the Boxster S is the clear winner.
The Porsche Boxster offers:
Refined and responsive handling.
Easier power application during cornering.
A more enjoyable driving experience overall.
The BMW Z4 M40i:
Features sharp turn-in but feels harder to balance.
Requires more effort to maintain consistent performance.
Braking and Stability Control
Braking performance is another area where the Porsche 718 Boxster excels. It stops from 60 to 0 mph in just 99 feet, compared to the Z4’s 103 feet. Even in wet conditions, the Boxster outperforms, stopping in 119 feet versus the Z4’s 122 feet.
718 Boxster | Z4 | |
|---|---|---|
70 to 0 MPH | 143 feet | 148 feet |
60 to 0 MPH | 99 feet | 103 feet |
60 to 0 MPH (Wet) | 119 feet | 122 feet |
The Boxster also offers optional ceramic brake rotors, which resist rust and fade while enhancing braking and handling. The Z4 doesn’t provide this option, making the Boxster a better choice for those who demand top-tier braking performance.
If you’re looking for a roadster that combines acceleration, responsive handling, and superior braking, the Porsche Boxster S stands out as the ultimate performer.

Steering Feel and Responsiveness
When it comes to steering, the Porsche 718 Boxster sets a high bar. Its steering feels precise and perfectly balanced, giving you a sense of harmony with the car. Professional drivers often rave about its feedback, describing it as granular and highly informative. It’s like the car is sampling the road at a higher frequency, letting you feel every detail. After driving the Boxster, you might find yourself becoming a “steering snob,” as one driver put it.
The BMW Z4, on the other hand, doesn’t quite match up. Its M Sport steering wheel feels bulky, and the variable-ratio rack can be too quick and imprecise. Some drivers even describe the Z4’s steering as abrupt and numb, making it harder to judge corners. If you value a connected and intuitive driving experience, the Boxster S clearly outshines the Z4.
Ride Quality and Suspension
The Porsche Boxster S doesn’t just excel in handling—it also delivers a smoother ride. Its suspension absorbs road imperfections effortlessly, making it feel composed even on rough surfaces. Whether you’re cruising through city streets or tackling winding backroads, the Boxster offers a level of comfort that’s hard to beat.
The BMW Z4 M40i, while cushioned, doesn’t handle bumps as effectively. It tends to find imperfections that the Boxster simply glides over. Although the Z4’s rigidity helps it shrug off some road irregularities, it doesn’t match the sophistication of the Boxster’s suspension. If ride quality matters to you, the Porsche 718 Boxster is the clear winner.
Transmission Options and Gear Shifts
Both cars offer automatic transmissions, but they cater to different driving styles. The BMW Z4 features an eight-speed automatic that’s perfect for urban settings and highway cruising. It provides smooth shifts and enhances acceleration, making it a great choice for comfort-focused drivers.
The Porsche 718 Boxster S, however, comes with a seven-speed automatic designed for sportier performance. Its shifts feel quicker and more engaging, prioritizing the thrill of driving over comfort. If you’re looking for a transmission that complements a spirited driving experience, the Boxster S delivers in spades.
Véhicule | Type de transmission | Driving Dynamics Impact |
|---|---|---|
BMW Z4 | Eight-speed automatic | Provides comfort in urban settings and better acceleration on highways |
Porsche 718 Boxster | Seven-speed automatic | Designed for sportier performance, less focus on comfort |
The choice here depends on your priorities. Do you want a relaxed drive or a more dynamic experience? Either way, both options have their strengths.
Design and Interior Features
Exterior Styling and Road Presence
When you first see the Porsche 718 Boxster and BMW Z4 M40i, their design philosophies immediately stand out. The Boxster’s mid-engine layout not only enhances its handling but also gives it a sleek, timeless silhouette. It’s a car that screams performance without being overly flashy. On the other hand, the Z4 M40i leans into modern aesthetics with sharp lines and a bold front grille. Its aerodynamic design isn’t just for looks—it achieves a drag coefficient as low as 0.29, compared to the Boxster’s 0.31. This makes the Z4 quieter at high speeds and slightly more fuel-efficient.
Car Model | Drag Coefficient (Cd) |
|---|---|
BMW Z4 M40i | 0.29 to 0.31 |
Porsche 718 Boxster | 0.31 to 0.34 |
Both cars have undeniable road presence. The Z4’s aggressive stance and wide kidney grille turn heads, while the Boxster’s understated elegance appeals to purists. Whether you prefer the Z4’s modern flair or the Boxster’s classic charm, both will make you feel like a star on the road.
Interior Comfort and Material Quality
Step inside, and you’ll notice the differences in their interiors. The BMW Z4 M40i feels luxurious with bright orange seats, intricate stitching, and power-adjustable options for lumbar support and lateral bolstering. It even offers extendable thigh support for added comfort. The Harman Kardon audio system, paired with textured metallic speaker grilles, adds a premium touch.
The Porsche Boxster, in contrast, opts for a minimalist approach. Its interior features manual seat adjustments and a smaller infotainment screen. Critics often describe it as a “sea of black” with subtle satin metallic trim. While it may lack the flashiness of the Z4, the Boxster’s simplicity appeals to those who value function over form.
If you’re looking for comfort and luxury, the Z4 takes the lead. But if you appreciate a no-nonsense, driver-focused cabin, the Boxster might be your pick.
Technology and Infotainment Systems
Technology plays a big role in modern roadsters, and both cars bring something unique to the table. The BMW Z4 M40i features a 10.3-inch touchscreen infotainment system with wireless Apple CarPlay. However, after the one-year trial, you’ll need a subscription to keep using it. The system is straightforward and easy to navigate, making it perfect for tech-savvy drivers.
The Porsche Boxster, on the other hand, offers a smaller infotainment screen that integrates seamlessly into the dashboard. It supports wired Apple CarPlay without any subscription fees. While it’s not as flashy as the Z4’s system, it’s fuss-free and gets the job done.
If you’re someone who loves cutting-edge tech, the Z4’s infotainment system will impress you. But if you prefer a simpler, more integrated setup, the Boxster’s system might suit you better.
Fun fact: Both cars offer infotainment systems that are more advanced than older classics like the miata or s2000, proving how far roadsters have come in blending performance with technology.
Cargo Space and Practical Usability
When it comes to cargo space, roadsters like the Porsche Boxster and BMW Z4 M40i aren’t exactly known for their practicality. However, both models offer unique solutions to make the most of their limited storage.
The BMW Z4 M40i features a single trunk that’s both wide and deep. This design makes it easier to load larger items, like a weekend bag or a small suitcase. With 9.9 cubic feet of cargo space, the Z4 is surprisingly practical for a two-seater. It even accommodates a compact spare tire, which can be a lifesaver if you’re traveling through rural areas where roadside assistance might not be readily available.
The Porsche Boxster, on the other hand, takes a different approach with its split trunk design. It offers a front trunk (or “frunk”) and a rear trunk, providing a combined cargo volume of 9.7 cubic feet. While this setup allows you to separate items, it can feel less practical for everyday use. The smaller compartments make it harder to fit bulkier items, and loading can be a bit of a puzzle.
In real-world scenarios, the Z4’s single, larger trunk often proves more convenient. Whether you’re heading out for a road trip or just running errands, its layout makes packing a breeze. The Boxster’s dual trunks, while clever, might leave you wishing for a bit more flexibility.
If you’re used to the minimal storage of classics like the miata or s2000, both cars will feel like an upgrade. But between the two, the Z4 edges out as the more practical choice for daily life. It’s a roadster that doesn’t just pass the test of performance but also adds a touch of everyday usability.
Value and Practicality
Pricing and Available Trims
When it comes to pricing, both the Porsche Boxster and BMW Z4 M40i offer a range of trims to suit different budgets. The BMW Z4 starts at $50,695, making it the more affordable option. With additional features and packages, the price can climb to $63,545. In the UK, the Z4 M40i starts at £48,535, with a fully loaded version reaching £51,985.
The Porsche Boxster, on the other hand, starts at a higher price point. The Boxster S begins at £53,714, while the more powerful GTS trim starts at £62,418. If you opt for all the bells and whistles, the total price can soar to £74,419. While the Z4 offers a more budget-friendly entry point, the Boxster justifies its premium pricing with its mid-engine layout and unmatched driving dynamics.
If you’re looking for a roadster that balances affordability and luxury, the Z4 might catch your eye. But if you’re willing to invest in a car that delivers top-tier performance, the Boxster could be worth the splurge.
Fuel Efficiency and Maintenance Costs
Fuel efficiency is another factor to consider. The BMW Z4 M40i achieves an impressive 33.2 mpg, making it one of the more economical choices in the roadster segment. The Porsche Boxster, while not as fuel-efficient, compensates with its thrilling performance.
Maintenance costs, however, might sway your decision. Over five years, the Z4’s ownership costs are estimated to be $6,610 to $18,960 less than the Boxster. This includes everything from fuel and insurance to repairs and maintenance. If you’re looking for a roadster that’s easier on your wallet in the long run, the Z4 takes the lead.
Resale Value and Long-Term Ownership Benefits
Resale value is where the Porsche Boxster shines. After three years, the Boxster retains its value better than the Z4 M40i. The Z4 tends to depreciate more significantly, with its value dropping nearly $20,000 in the same period. The Boxster’s established reputation and loyal fanbase contribute to its strong resale value.
That said, the Z4 has improved compared to previous generations. While it still lags behind the Boxster in value retention, it offers a more modern package that appeals to a broader audience. If you’re planning to keep your roadster for years, the Boxster might be the better investment.
Conseil de pro: If you’re coming from classics like the miata or s2000, you’ll find both the Z4 and Boxster to be a significant upgrade in terms of practicality and long-term value.
Choosing between the Porsche Boxster and BMW Z4 M40i ultimately depends on what you value most in a roadster. If you prioritize a thrilling driving experience, the Boxster S stands out with its mid-engine layout, precise steering, and quicker shifts. Its performance metrics, like a 0-60 mph time of 3.7 seconds and a quarter-mile finish in 12.0 seconds, showcase its edge over the BMW Z4.
Aspect | Porsche Boxster S | BMW Z4 M40i |
|---|---|---|
0-60 mph | 3,7 secondes | 3,9 secondes |
Quarter mile | 12.0 seconds at 116.0 mph | 12.3 seconds at 114.1 mph |
Steering feel | More informative | Less informative |
Ride quality | More connected to the road | Feels more cushioned |
On the other hand, the BMW Z4 M40i offers a more luxurious cabin, better tech integration, and a practical single trunk. It’s a roadster that blends comfort with performance, making it ideal for daily drives. While its handling feels less intuitive than the Boxster S, it still delivers an exciting ride.
Both cars are a significant upgrade from classics like the Miata or S2000, offering modern features and better usability. The Boxster excels in performance and long-term value, while the Z4 shines in comfort and affordability. Your choice comes down to whether you want a purist’s sports car or a refined, tech-savvy roadster. Either way, you’re in for an unforgettable experience.
