Wiesmann GT MF4 4.4 V8 (407 Hp) Automatic

The Wiesmann GT MF4 4.4 V8 Automatic, produced between 2003 and 2014, represents a unique offering in the high-performance sports car segment. Wiesmann, a German manufacturer known for its handcrafted, retro-styled roadsters and coupes, positioned the GT MF4 as its flagship model. The “MF4” designation signifies the model’s mid-front engine placement and four-liter displacement. This variant, powered by a 4.4-liter twin-turbocharged V8 engine paired with a six-speed automatic transmission, was the most potent offering in the GT lineup, aimed at buyers seeking a blend of luxury, performance, and exclusivity. It was built on a bespoke chassis, rather than sharing components with larger automotive groups.

Wiesmann GT MF4 4.4 V8: A Detailed Overview

The GT MF4 was conceived as a modern interpretation of classic British roadsters, blending handcrafted construction with contemporary German engineering. Unlike mass-produced sports cars, each Wiesmann was largely assembled by hand, contributing to its high price point and limited production numbers. The MF4 specifically targeted drivers who desired a powerful, comfortable grand tourer with a distinctive aesthetic. It occupied the top tier of the Wiesmann GT range, surpassing the earlier 3.2-liter and 3.7-liter models in both performance and refinement.

Powertrain & Engine Architecture

At the heart of the GT MF4 lies the BMW-sourced N63B44 engine, a 4.4-liter twin-turbocharged V8. This engine, internally designated as the 407 Hp variant by Wiesmann, produces 407 horsepower at 5500-6400 rpm and a substantial 600 Nm (442.54 lb-ft) of torque between 1750 and 4500 rpm. The engine features direct fuel injection, double-VANOS variable valve timing, and an intercooled twin-turbocharger system. The twin-turbo setup provides a broad torque curve, delivering strong acceleration throughout the rev range. The engine is mounted longitudinally in the front-mid position, contributing to a balanced weight distribution.

The transmission is a ZF 6HP26 six-speed automatic gearbox, known for its smooth shifting and durability. While not offering the direct engagement of a manual transmission, the automatic was calibrated to provide responsive shifts and allow the driver to maintain control of the engine’s power. The transmission features a torque converter and allows for both fully automatic operation and manual gear selection via steering wheel-mounted paddles or the gear selector. The drivetrain is rear-wheel drive, enhancing the car’s sporting character.

Driving Characteristics

The Wiesmann GT MF4 4.4 V8 Automatic delivers exhilarating performance. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 4.6 seconds, while 0 to 60 mph is achieved in around 4.4 seconds. The car boasts a top speed of 291 km/h (180.82 mph). The twin-turbo V8 provides instant throttle response and a relentless surge of power. The automatic transmission, while smooth, can feel slightly less engaging than a manual gearbox, but it contributes to the car’s ease of driving. The relatively low curb weight of 1455 kg (3207.73 lbs) further enhances the car’s agility and handling. The car’s weight distribution, aided by the front-mid engine placement, contributes to neutral handling characteristics.

Equipment & Trim Levels

The Wiesmann GT MF4 was characterized by a high level of customization. While a base specification existed, customers could extensively personalize their vehicles with a wide range of options. Standard equipment typically included leather upholstery, air conditioning, power windows, and a high-end audio system. Interior trim could be specified in a variety of colors and materials, including premium leather, wood veneer, and carbon fiber. Optional extras included navigation systems, heated seats, and bespoke interior detailing. The dashboard layout was relatively simple and driver-focused, emphasizing functionality over excessive ornamentation. Exterior paint options were also extensive, allowing customers to create a truly unique vehicle.

Chassis & Braking

The GT MF4 utilizes a steel space frame chassis, providing a rigid and lightweight foundation for the vehicle. Suspension is handled by a double wishbone setup at both the front and rear, offering a balance of comfort and handling precision. The braking system consists of ventilated discs all around, providing ample stopping power. Anti-lock Braking System (ABS) is standard. The car rides on 18-inch alloy wheels, typically fitted with 245/45 R18 tires. The suspension was tuned to provide a comfortable ride for long-distance cruising, while still maintaining a firm and controlled feel during spirited driving.

Market Reception & Comparison

The Wiesmann GT MF4 4.4 V8 Automatic received generally positive reviews from automotive journalists. Critics praised its powerful engine, handcrafted construction, and distinctive styling. However, the car’s high price and limited availability were often cited as drawbacks. Compared to other high-performance coupes of the era, such as the Porsche 911 or Aston Martin V8 Vantage, the GT MF4 offered a unique blend of luxury and performance. Fuel economy, at 12.3 l/100 km (19.1 US mpg), was typical for a vehicle of this type. Reliability was generally good, benefiting from the use of proven BMW engine technology, although maintenance costs could be high due to the car’s specialized nature and limited parts availability. The car’s CO2 emissions were rated at 285 g/km, meeting Euro 5 standards.

Technical Specifications

Legacy

The Wiesmann GT MF4 4.4 V8 Automatic remains a sought-after vehicle among collectors and enthusiasts.
