Wiesmann Thunderball EV Prototype: 2025 First Drive Review

The Wiesmann Project Thunderball prototype marks a daring renaissance for the German sports car maker, merging nostalgic design cues with state-of-the-art electric propulsion. This two-seater convertible promises to deliver supercar thrills without a drop of fuel, targeting enthusiasts who crave heritage-inspired aesthetics alongside modern zero-emission performance.

Heritage Meets High-Tech Innovation

Wiesmann, once celebrated for its handcrafted roadsters powered by BMW V8 engines, faced bankruptcy in 2014 but has roared back with an all-electric vision. The Thunderball prototype evolves from a planned V8 model, adapting its core structure to accommodate a sophisticated EV powertrain. This shift preserves the brand’s signature gecko-eyed front fascia and elongated hood while introducing lightweight carbon-fiber bodywork—a upgrade from the glass-fiber used in earlier models.

The chassis, a bonded-and-riveted aluminum spaceframe, underpins the entire vehicle, providing rigidity essential for high-performance handling. At approximately 1,775kg (3,900lb curb weight), it strikes a balance between agility and the heft of its 83kWh battery pack. This T-shaped battery, developed in collaboration with Roding Mobility, fits neatly into the engine bay and former transmission tunnel, weighing just 110 pounds more than a traditional V8 and gearbox combo.

Powertrain: Electric Muscle in Disguise

At the heart of the Thunderball lies a dual-motor setup delivering a claimed 680hp (671hp per some specs) and 1,100Nm (811lb-ft) of torque. These axial-flux permanent-magnet synchronous motors, mounted amidships, drive a common shaft connected to a limited-slip rear differential via a single-speed direct-drive transmission. Unlike conventional radial-flux motors, the axial design offers superior power density despite a 9,000rpm redline.

The 800-volt architecture supports rapid charging up to 300kW DC, with a 22kW onboard AC charger. Wiesmann targets a WLTP range of around 300 miles, bolstered by active liquid cooling using a water-glycol mix. In prototype form, output is detuned to about 437hp for safety during development, yet it still propels the car from 0-62mph in 2.9 seconds—matching or exceeding prior V8 Wiesmanns.

Regenerative braking, adjustable via steering-wheel paddles across five levels, enables one-pedal driving without overly aggressive deceleration. This setup mimics the progressive power delivery of classic V8s, avoiding the abrupt surge common in many EVs.

Design: Timeless Appeal with Modern Refinements

The Thunderball’s silhouette evokes 1950s grand tourers, with a wider stance than predecessors for improved stability. Its carbon-fiber panels gleam under sunlight, accented by a massive billet-aluminum grille—now purely aesthetic since there’s no radiator to cool. The open-top layout emphasizes wind-in-the-hair motoring, complete with a compact 180-liter frunk and additional rear storage totaling about 10 cubic feet.

• Exterior Highlights: Sharper lines, retro proportions, carbon body for reduced weight.
• Dimensions: 174.8 inches long, 102.2-inch wheelbase, 50.6 inches tall.
• Wheels: Large alloys wrapped in performance tires for grip.

Inside, the cabin blends vintage flair with EV necessities. A driver-focused dashboard features laser-etched analog gauges, including a charming ‘clock’ for battery state-of-charge. Hand-stitched leather envelops seats and surfaces, creating a premium, bespoke ambiance. Small circular dials cluster centrally, angled toward the pilot, while digital displays relay power, torque, and thermal data in real-time.

On the Road: Prototype Poise and Promise

Despite its developmental status, the Thunderball prototype inspires confidence from the first turn of the keyless ignition. Power builds smoothly, urging the rear wheels forward with precision rather than violence. On winding German backroads, it shadowed a V8-powered MF4 sibling, demonstrating comparable pace minus the drama of revs and exhaust notes.

Steering is precise and communicative, though some reviewers noted a touch of dartiness in the prototype—likely to be refined. The chassis exhibits excellent balance, with minimal body roll and a planted feel through corners. Suspension shimmies occasionally hint at ongoing tuning, but overall dynamics feel production-ready. Braking is strong, aided by regen, and the low center of gravity from the battery enhances cornering poise.

Even detuned, the Thunderball’s acceleration feels eager and controlled, hinting at the full-fat version’s sub-three-second sprint capability.

Quieter than its V8 forebears, the EV relies on synthetic sounds or road noise for auditory feedback. This subtlety shifts focus to tactility: the weighted shifter, supple ride over undulations, and telepathic front-end response.

Challenges and Future Prospects

As a prototype, thermal management limits sustained high output, causing derating during repeated sprints—like hitting molasses, per one tester. Battery cooling refinements from Roding Mobility will address this for production. Range claims hold promise, but real-world figures may vary with driving style and conditions; EPA estimates suggest around 250 miles.

Production begins in 2024 at Wiesmann’s German facility, with first customer cars in 2025. Limited to 100 units annually, each will be customizable. At circa £250,000 ($320,000), it targets collectors valuing exclusivity over mass-market EVs.

Comparing to Rivals

The Thunderball stands out for its analog soul in an EV world, offering a purer roadster experience than hyper-EVs.

Why It Matters: Electric Evolution for Purists

For purists mourning the V8’s roar, Thunderball proves electrification needn’t dilute driving joy. Its retro-modern ethos could redefine the roadster segment, blending sustainability with soul. As batteries improve, expect even greater ranges and power without weight penalties.
