Dutton Commander S2: Amphibious 4WD Review, Specs & Facts

The Dutton Commander S2 redefines versatility in the world of specialized vehicles. Built on a robust Suzuki platform, this amphibious 4WD machine seamlessly transitions from rugged terrain to open water, offering drivers an unmatched dual-purpose experience. Whether tackling muddy trails or navigating calm lakes, its design prioritizes practicality, affordability, and genuine off-road capability.

Origins and Engineering Foundations

Developed by Dutton, a British specialist in kit cars and amphibious conversions, the Commander S2 draws heavily from Suzuki’s reliable Jimny lineup. This choice ensures a strong base with proven 4WD mechanics, making it fully road-registerable in multiple countries. Available in petrol or diesel variants, it caters to diverse preferences for power and efficiency.

The vehicle’s hull integrates seamlessly with the chassis, allowing submersion without compromising structural integrity. Propulsion in water comes from the road wheels, eliminating the need for separate marine drives—a cost-saving feature that enhances simplicity. This engineering approach positions the S2 as a ‘works-out-of-the-box’ solution for enthusiasts seeking amphibious thrills without exorbitant prices.

Powertrain and Performance Specifications

At its core, the Commander S2 employs a 1300cc petrol or 1500cc diesel engine sourced from Suzuki. These units deliver adequate power for both terrestrial and aquatic demands. On land, the true 4WD system shines in low-traction scenarios, providing torque distribution across all wheels for superior grip.

Land performance prioritizes low-end torque over high-speed prowess. Acceleration to 60 mph takes around 13 seconds, with handling tuned for mud-plugging rather than track days. In water, it achieves practical speeds governed by its full-displacement hull design, which prevents planing but ensures stability.

Real-World Achievements: Conquering the English Channel

One of the most compelling endorsements of the Commander S2’s capabilities came in 2006, when two units successfully crossed the English Channel from Dover to Calais. Completing the journey in 7 hours and 5 minutes, this feat highlighted the vehicle’s endurance in challenging marine conditions. Despite less-than-ideal weather and minimal preparation, the crossing raised awareness for a wildfowl reserve, underscoring the S2’s reliability.

While not matching record times set by specialized amphibians like the Gibbs Aquada (1 hour 40 minutes), the S2’s success stems from its everyday usability. In optimal conditions, sub-5-hour crossings are feasible, proving its potential for serious aquatic endeavors.

On-Road Dynamics and Handling

Behind the wheel, the Commander S2 exudes character suited to adventure over refinement. Its elevated ride height offers commanding visibility, beneficial for off-road navigation. The 5-speed manual gearbox channels power effectively, though top-end performance tapers off beyond 90 mph due to engine limitations and aerodynamics.

• Steering: Direct but vague at speed, ideal for trail work.
• Brakes: Functional for the vehicle’s purpose, with a 3-star safety rating reflecting its niche focus.
• Ride Comfort: Extended wheelbase compared to stock Jimny reduces harshness on rough surfaces.
• Weight: Approximately 100 kg heavier than base models, enhancing stability.

Corners demand caution due to body roll, but this aligns with its mud-terrain ethos rather than sporty aspirations.

Aquatic Capabilities and Water Handling

Transitioning to water mode is straightforward: seal hatches, engage low gear, and drive off the ramp. The propelling wheels maintain momentum, with the hull’s displacement design ensuring predictable handling. Limited to around 6 mph, it prioritizes safety over speed, avoiding the risks of planing hulls.

Users report confident operation in rivers, lakes, and coastal waters. The 4WD system aids beach launches, while corrosion-resistant materials protect against prolonged exposure. For extended voyages like the Channel crossing, fuel efficiency and durability prove pivotal.

Build Options: Kit vs. Factory Assembly

Dutton offers the S2 as a kit for DIY builders or fully assembled from their Littlehampton, West Sussex facility. A diesel-powered ready-to-drive model priced under £20,000 (~$50,000 AUD equivalent) in early models made it accessible.

Left- or right-hand drive configurations accommodate global markets, excluding UK VAT for exports starting at £25,490. Kit assembly appeals to tinkerers, leveraging Suzuki donor parts for familiarity.

Comparisons with Other Amphibians

Unlike the Amphicar’s 4,000-unit sales but sluggish performance, the S2 emphasizes modern 4WD utility. The Dutton Reef, a Fiesta-based sibling, offers mid-engine layout and two-wheel drive but shares the 6 mph water limit. Gibbs models boast speed yet falter in production volume.

The S2’s balance of cost, legality, and capability sets it apart for practical adventurers.

Practical Ownership Considerations

Maintenance mirrors Suzuki servicing, with amphibious-specific checks for seals and hull integrity. Fuel economy suits mixed use, and insurance is feasible due to road approval. Storage requires dry conditions to prevent mold, but its lightweight build aids trailering.

Customization options include engine upgrades for better land pace, though water performance remains hull-limited. Community forums praise its fun factor, dubbing it a ‘pint-sized mud plugger’ with boat bonuses.

Modern Relevance and Legacy

Though rooted in 2000s tech, the S2’s design endures for rescue operations, expeditions, and recreation. Its Channel-crossing legacy cements status among amphibious icons, inspiring ongoing interest in dual-domain vehicles.
