Wiesmann Roadster MF4 S 4.0 V8 (420 Hp)

The Wiesmann Roadster MF4 S 4.0 V8, produced between 2009 and 2014, represents the high-performance pinnacle of the MF4 Roadster generation. Wiesmann, a German manufacturer known for its handcrafted, retro-styled roadsters, positioned the MF4 S as its flagship model, offering a significantly more potent and exclusive experience than the standard MF4. Built on a bespoke chassis, the MF4 S aimed to deliver a classic roadster feel combined with modern performance and luxury. It catered to enthusiasts seeking a unique, hand-built alternative to mainstream sports cars.

Wiesmann Roadster MF4 S: A Detailed Overview

The MF4 S distinguished itself from the base MF4 through its larger, more powerful V8 engine, upgraded suspension components, and enhanced interior appointments. It was a deliberate move upmarket for Wiesmann, emphasizing exclusivity and driving pleasure. The “S” designation signified a substantial increase in both power and performance, solidifying its position as a true sports car contender. Production numbers remained limited, further enhancing its desirability among collectors and driving enthusiasts.

Powertrain & Engine Architecture

At the heart of the MF4 S lies a naturally aspirated 4.0-liter V8 engine, sourced from BMW. Specifically, it utilized the S65 engine code, renowned for its high-revving character and robust construction. This engine produced 420 horsepower at 8300 rpm and 400 Nm (295.02 lb-ft) of torque at 3900 rpm. The engine featured individual throttle bodies, a high compression ratio of 12:1, and a sophisticated double-VANOS variable valve timing system. The engine layout is front-mounted and longitudinal, driving the rear wheels. Fuel is delivered via direct injection, contributing to both performance and efficiency. The engine’s design prioritized a linear power delivery and a thrilling exhaust note.

The MF4 S was exclusively offered with a 6-speed manual transmission. This choice underscored Wiesmann’s commitment to a pure driving experience, allowing drivers full control over the engine’s power. The transmission was sourced from Getrag and known for its precise shifts and durability. The rear-wheel drive configuration, combined with the manual gearbox, provided a classic sports car driving dynamic.

Driving Characteristics

The driving experience in the MF4 S is characterized by its responsiveness and engaging nature. The 4.0-liter V8 delivers strong acceleration throughout the rev range, with a particularly exhilarating surge towards the redline. The 0-60 mph sprint is achieved in approximately 4.2 seconds, and the car boasts a top speed of 182.06 mph (293 km/h). The manual transmission encourages active participation, while the rear-wheel drive setup provides excellent balance and handling. The relatively lightweight construction (1390 kg / 3064.43 lbs) contributes to its agility and nimble cornering ability. The suspension, tuned for performance, offers a firm but controlled ride, providing ample feedback to the driver. While not designed for everyday comfort, the MF4 S excels on winding roads and open highways.

Equipment & Trim Levels

The MF4 S was largely bespoke, with a high degree of customization available to buyers. Standard features included leather upholstery, air conditioning, power windows, and a high-end audio system. However, the emphasis was on personalization. Customers could select from a wide range of leather colors, wood trims, and exterior paint options. Optional extras included navigation systems, upgraded sound systems, and various aerodynamic enhancements. The interior was designed to evoke a classic roadster aesthetic, with a focus on craftsmanship and quality materials. The dashboard layout was relatively simple and driver-focused, with clearly legible gauges and intuitive controls.

Chassis & Braking

The MF4 S utilized a steel space frame chassis, providing a rigid and lightweight foundation for the vehicle. Suspension consisted of double wishbones at both the front and rear, optimized for handling and stability. Ventilated disc brakes were fitted on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) was standard. The car rode on 18-inch alloy wheels, shod with 245/45 R18 tires, contributing to both grip and aesthetics. The suspension geometry was carefully tuned to minimize body roll and maximize cornering performance.

Market Reception & Comparison

The Wiesmann MF4 S received generally positive reviews from automotive journalists, who praised its performance, handling, and exclusivity. Critics noted its unique styling and handcrafted quality as key differentiators. However, the high price tag and limited availability restricted its appeal to a niche market. Compared to other sports cars in its price range, such as the Porsche 911, the MF4 S offered a more individual and bespoke experience. While the Porsche offered a broader range of practicality and refinement, the Wiesmann prioritized raw driving pleasure and exclusivity. Fuel economy was not a strong point, with combined consumption figures of 12.4 l/100 km (19 US mpg). Reliability was generally good, benefiting from the use of proven BMW components, but maintenance costs could be high due to the car’s specialized nature.

Technical Specifications

Legacy

The Wiesmann MF4 S 4.0 V8 remains a highly sought-after vehicle among collectors and enthusiasts. Its limited production numbers and unique character ensure its continued desirability. The S65 V8 engine, known for its reliability and performance, is a key factor in its long-term appeal. While maintenance can be expensive, the car’s robust construction and use of proven components contribute to its durability. In the used car market, the MF4 S commands a premium price, reflecting its exclusivity and the passion it inspires. It stands as a testament to Wiesmann’s commitment to handcrafted quality and the enduring appeal of the classic roadster formula.
