2009 Wiesmann Roadster MF4 Dimensions, Size & Specs

The curb weight of the Wiesmann Roadster MF4 ranges from 1390 to 1455 kilograms (approximately 3062 to 3209 pounds). This relatively light weight for a modern roadster is significant because it directly influences the car's handling, acceleration, and braking performance. The lower weight improves responsiveness and agility, making the driving experience more engaging and dynamic. Additionally, the balanced weight distribution typical of Wiesmann vehicles contributes to excellent cornering stability and driver confidence. The lightweight construction often utilizes a mix of materials aimed at optimizing strength and rigidity without unnecessary mass, highlighting Wiesmann's commitment to delivering a purist sports car feel.

The Wiesmann Roadster MF4 is equipped with rims sized at 8J x 18 inches coupled with tire dimensions of 245/45 R18. These 18-inch wheels strike a balance between style, performance, and ride quality. The wide 245 mm tires provide a substantial contact patch with the road, enhancing grip during acceleration, braking, and cornering. The 45 aspect ratio of the tires also helps preserve ride comfort by providing adequate sidewall height to absorb road imperfections. This combination contributes to precise steering feedback and stability at high speeds, which are essential qualities in a sports-oriented roadster like the MF4. Overall, these specifications underline Wiesmann's focus on performance and driver involvement.

With a length of 4230 mm (166.5 inches), a width of 1880 mm (74 inches), and a height of 1190 mm (46.9 inches), the Wiesmann Roadster MF4 is compact enough to fit comfortably in most standard residential garages. Typical garage spaces measure roughly 2.4 to 3 meters (7.9 to 9.8 feet) in width and about 5.5 meters (18 feet) in depth, dimensions that easily accommodate the MF4’s footprint. Its lower height compared to standard passenger cars helps with maneuvering under typical garage door clearances, and the moderate width allows for adequate space around the vehicle when parked. Therefore, owners of the Roadster MF4 should expect no difficulty in garage storage in standard home setups.

The Wiesmann Roadster MF4 built upon the heritage of the earlier MF3 model but introduced several dimensional refinements suited to modern performance requirements. Compared to the predecessor, the MF4 was slightly longer and wider, with its 4230 mm length and 1880 mm width offering a more muscular stance. Height at 1190 mm remained lower than many conventional vehicles, preserving the sleek, aerodynamic profile that Wiesmann is known for. These dimension increases allowed for improved stability and interior space without compromising the traditional lightweight and agile handling traits. This evolutionary change ensured that the MF4 felt more contemporary while maintaining the distinct roadster charm valued by enthusiasts.

When compared to its peers in the luxury roadster segment, such as the Porsche Boxster or BMW Z4, the Wiesmann Roadster MF4 is generally comparable yet distinctive in specific ways. Its 4230 mm (166.5 inches) length and 1880 mm (74 inches) width position it within a similar footprint, though the MF4's notably lower height of 1190 mm (46.9 inches) is more pronounced, accentuating its aerodynamic and retro-modern appeal. The curb weight of 1390 to 1455 kg also falls into a similar lightweight sports car range, enabling superior agility and responsiveness. However, the MF4 stands out with its hand-built craftsmanship and unique styling, making it not just a sports car but also a collectible luxury roadster compared to more mass-produced rivals.

The Wiesmann Roadster MF4 is designed primarily as a two-seat sports car with a focus on driver engagement rather than extensive interior space. Due to its compact dimensions—with a length of 4230 mm and a fairly low height of 1190 mm—the cabin is snug but ergonomically optimized for a comfortable driving posture. Seating is typically low-slung to complement the car's sporty handling, and the interior offers sufficient legroom and headroom for drivers and passengers up to average height. However, taller occupants might find headroom slightly limited due to the low roofline. The minimalist interior design emphasizes premium materials and driver-focused controls rather than expansive space, consistent with its roadster ethos.

Yes, the Wiesmann Roadster MF4’s dimensions directly inform its aerodynamic design, which is crucial for high-performance roadsters. Its low overall height of just 1190 mm (46.9 inches) helps reduce air resistance and drag, which increases top speed and efficiency. The wide stance (1880 mm or 74 inches) enhances stability at higher velocities by providing increased lateral grip. Additionally, the relatively compact length (4230 mm or 166.5 inches) allows for a streamlined shape with gentle curves, reducing turbulent airflow around the body. These dimensional elements, combined with aerodynamic styling cues such as smooth surfaces and carefully sculpted lines, enable the MF4 to maintain excellent airflow management and optimal downforce for spirited driving.

While official figures for the Wiesmann Roadster MF4's ground clearance are less frequently published, typical sports cars with similar dimensions generally have a ground clearance between 100 to 130 mm (approximately 4 to 5 inches). This relatively low clearance complements the car’s sporty nature and helps lower the center of gravity for improved handling and agility around corners. However, such a low ground clearance means that everyday usability can be affected by speed bumps, steep driveways, or uneven road surfaces, requiring careful navigation to avoid underbody scraping. Owners should expect the MF4 to perform best on smooth, well-maintained roads rather than rough or unpaved surfaces.

The Wiesmann Roadster MF4, being a lightweight two-seater roadster, is not designed with towing in mind and thus does not feature a rated towing capacity, making it unsuitable for pulling trailers or heavy loads. In terms of luggage, the boot space is modest, consistent with its sports car layout. The rear storage area is tailored for light luggage and essential items rather than volume, reflecting the car’s primary focus on performance and driver experience rather than utility. This limited cargo space is standard for vehicles in this category, reinforcing the MF4's identity as a sporty, stylish roadster meant for enjoyment rather than practical transport.
