Honda S800 (1966-70)
The Honda S800 (1966–1970) was a bold declaration of Honda’s engineering ambition — a compact sports car that fused motorcycle DNA with precision automotive design. It wasn’t just a product; it was Honda’s way of saying, “We belong in the world of performance cars.” Here's how the concept and intention unfolded:
---
🧭 **Core Concept: A Jewel-Like Sports Car for the Masses**
- **Accessible performance**: Honda aimed to deliver a sports car experience in a small, affordable package — something that could excite without intimidating.
- **Engineering showcase**: The S800 was a technical marvel, designed to highlight Honda’s mastery of high-revving engines and lightweight construction.
- **Flagship identity**: It became Honda’s image car, representing the brand’s shift from motorcycles to automobiles with flair and precision.
---
🔧 **Engineering Intentions**
- **Motorcycle-inspired engine**: The 791cc inline-four featured twin cams, roller-bearing crankshaft, and dual carburetors — revving to 9,000 RPM and producing 70 hp.
- **Chain-driven rear suspension**: Early models used chain cases as trailing arms, a nod to Honda’s motorcycle heritage and a clever solution for independent rear suspension.
- **Ladder-frame chassis**: Compact and rigid, it supported the car’s nimble handling and lightweight ethos.
---
🎨 **Design Philosophy**
- **Compact elegance**: With clean lines and tight proportions, the S800 looked purposeful yet refined — a true roadster with a fixed-head coupe option introduced later.
- **Driver-focused layout**: Minimalist interior with clear instrumentation and snug seating emphasized the driving experience.
---
📊 **Market Positioning**
- **Tax-friendly engineering**: Originally conceived as a 360cc car to fit Japan’s tax incentives, the concept evolved into a more powerful model for broader appeal.
- **Global reach**: Though aimed at the Japanese market, left-hand-drive versions were exported to Europe and the U.S., often through personal imports.
- **Racing spirit**: Honda wanted the car to give “a taste of what a competition vehicle was like” — and it did, with several S600/S800s racing in the UK and Australia.
---
🏆 **Legacy and Impact**
- **Foundation for future icons**: The S800 laid the groundwork for Honda’s later sports cars, including the S2000 — both sharing a love for high-revving engines and driver purity.
- **Cult admiration**: Today, it’s celebrated as a forgotten gem — a car that dared to be different and succeeded through sheer engineering brilliance.

COMMON FAULTS
Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.
The Honda S800, like many classic cars, has its share of common faults. Here are a few issues that owners often encounter:
1. **Engine Overheating**: The high-revving engine can sometimes overheat, especially in hot weather or during extended drives.
2. **Electrical Problems**: The electrical system can be prone to faults, including issues with the alternator and wiring.
3. **Rust**: As with many cars from this era, rust can be a significant problem, particularly in the chassis and body panels.
4. **Carburettor Issues**: The twin carburettors can be tricky to tune and may require regular maintenance to keep the engine running smoothly.
5. **Suspension Wear**: The suspension components can wear out over time, leading to a less comfortable ride and handling issues.
If you're considering buying or restoring a Honda S800, it's essential to be aware of these potential problems and be prepared for regular maintenance.

Generations/Trim Levels
Please Note: Generations and Trim Levels Across Countries
Generations and trim levels of vehicles often vary between countries as manufacturers tailor models to meet the preferences and requirements of specific markets. For example, a trim level designated as “GL” in the UK might be labelled as “XS” in another country. Due to these regional differences, the information provided on this site pertains exclusively to UK-specific products.
The Honda S800 had only one generation, produced from 1966 to 1970. It was available in two main body styles: a roadster (convertible) and a coupé - autoevolution](https://www.autoevolution.com/honda/s800/).
As for trim levels, the S800 didn't have multiple trims like modern cars. However, there were some variations and updates during its production run:
1. **Early Models (1966-1967)**: These models featured chain-driven rear wheels and independent rear suspension.
2. **Later Models (1967-1970)**: These models switched to a more conventional drive-shaft and live axle rear end with four radius rods and a Panhard rod. They also included updates like disc brakes replacing the front drums.
In 1968, the S800M (also known as S800MK2) was introduced with additional safety features and minor design changes, such as flush-mounted interior door handles, side marker lights, dual-circuit brakes, and lean burn carburetion.
