Wiesmann GT MF4 S 4.0 V8 (420 Hp) Automatic

The Wiesmann GT MF4 S 4.0 V8 Automatic, produced between 2003 and 2014, represents the high-performance pinnacle of the first-generation Wiesmann GT (codenamed GT MF4). This model, a two-seat, two-door coupe, distinguished itself within the Wiesmann lineup as the most powerful variant, offering a significant step up in performance and exclusivity compared to earlier, less potent versions. The “MF4” designation signifies the model’s mid-front engine placement and four-wheel drive configuration, although the S 4.0 V8 variant is rear-wheel drive. The GT MF4 S catered to enthusiasts seeking a handcrafted, luxurious grand tourer with genuine sports car credentials.

Wiesmann GT MF4 S: A Performance Overview

The GT MF4 S 4.0 V8 Automatic was positioned as the flagship model of the Wiesmann GT range. While the initial GT models utilized BMW inline-six engines, the MF4 S introduced a naturally aspirated 4.0-liter V8 engine sourced from BMW’s M division, significantly elevating the car’s performance capabilities. This variant targeted buyers who desired a more visceral and engaging driving experience than the earlier, more comfort-oriented models. It competed with other high-end sports cars and grand tourers, such as the Porsche 911, Aston Martin Vantage, and Maserati GranTurismo, offering a unique blend of German engineering and bespoke craftsmanship.

Powertrain & Engine Architecture

At the heart of the GT MF4 S lies the BMW S65B40 engine, a 3,999 cc (244.03 cu. in.) naturally aspirated V8. This engine, also found in the BMW M3 (E46) and M5 (E60), is renowned for its high-revving nature and linear power delivery. The engine boasts a bore of 92 mm (3.62 in.) and a stroke of 75.2 mm (2.96 in.), with a compression ratio of 12:1. It produces a maximum power output of 420 hp (313 kW) at 8,300 rpm and 400 Nm (295.02 lb-ft) of torque at 3,900 rpm. The engine features double VANOS (Variable Valve Timing) for both intake and exhaust valves, optimizing performance and efficiency across the rev range.

The engine is mated to a 7-speed automatic transmission, providing smooth and relatively quick gear changes. While a manual transmission was not offered on the MF4 S, the automatic transmission was specifically tuned to complement the V8 engine’s characteristics. The drivetrain is rear-wheel drive, contributing to the car’s dynamic handling balance. The engine is longitudinally mounted in the front of the vehicle, contributing to a favorable weight distribution.

Driving Characteristics

The Wiesmann GT MF4 S delivers a thrilling driving experience characterized by its responsive throttle, sharp steering, and potent acceleration. 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 automatic transmission, while offering convenience, is programmed for performance, holding gears longer and downshifting quickly under braking. The car’s relatively lightweight construction (1,370 kg / 3,020.33 lbs) further enhances its agility and responsiveness. Compared to earlier GT models with inline-six engines, the MF4 S offers a significantly more powerful and engaging driving experience, with a more pronounced exhaust note and a greater sense of urgency.

Equipment & Trim Levels

The Wiesmann GT MF4 S was characterized by its high level of customization and luxurious interior appointments. Standard features included leather upholstery, air conditioning, power windows, and a high-end audio system. The interior was handcrafted with meticulous attention to detail, offering a bespoke feel. Customers could specify a wide range of interior trim options, including different leather colors, wood veneers, and stitching patterns. Optional extras included navigation systems, heated seats, and upgraded audio systems. The exterior was typically finished in a high-quality paint finish, with customers able to choose from a variety of colors. The car’s design, inspired by classic British roadsters, featured prominent wheel arches, a long hood, and a short rear deck.

Chassis & Braking

The GT MF4 S utilizes a double wishbone suspension system at both the front and rear, providing a comfortable yet controlled ride. The suspension geometry was carefully tuned to optimize handling and stability. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during hard braking. The car rides on 18-inch alloy wheels, fitted with 245/45 R18 tires. The chassis is constructed from a combination of steel and aluminum, balancing strength and weight.

Market Reception & Comparison

The Wiesmann GT MF4 S was generally well-received by automotive critics, who praised its performance, handling, and luxurious interior. However, its high price tag and limited production numbers meant it remained a niche product. Compared to other models in the Wiesmann lineup, the MF4 S offered a significant performance advantage, but at a considerable premium. Fuel economy was not a strong point, with combined fuel consumption of 12.3 l/100 km (19.1 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 and the need for skilled technicians.

Technical Specifications

Legacy

The Wiesmann GT MF4 S 4.0 V8 Automatic remains a highly sought-after vehicle among collectors and enthusiasts. Its combination of performance, luxury, and exclusivity ensures its continued appeal. The BMW S65 V8 engine is known for its durability and tunability, making the MF4 S a relatively reliable sports car. However, as with any specialized vehicle, regular maintenance and careful ownership are essential. In the used car market, the MF4 S commands a premium price, reflecting its rarity and desirability. It represents a unique chapter in automotive history, showcasing the artistry and engineering prowess of a small, independent manufacturer.
