Honda S660: Which Version to Buy and Why
The Honda S660 has one generation and two versions: 0.7 MT and 0.7 CVT. Both are Roadsters with the same 660 cc turbocharged Gasoline engine, 64 hp, 47 kW, 104 Nm, RWD, 830 kg kerb weight, 125 mm ground clearance, and a top speed of 140 km/h.
The Honda S660 has one generation and two versions: 0.7 MT and 0.7 CVT. Both are Roadsters with the same 660 cc turbocharged Gasoline engine, 64 hp, 47 kW, 104 Nm, RWD, 830 kg kerb weight, 125 mm ground clearance, and a top speed of 140 km/h. The decisive difference is the gearbox and its effect on acceleration: the 0.7 MT uses a 6-speed Manual and reaches 100 km/h in 12.6 seconds, while the 0.7 CVT uses a Variable gearbox and takes 13.4 seconds. On the available figures, the 0.7 MT is the stronger performance choice; the 0.7 CVT is the alternative for buyers who specifically prefer a Variable transmission.
Honda S660 generations and versions
The Honda S660 has 1 generation, which started in 2015. This generation is a Roadster and contains 2 versions, the 0.7 MT and 0.7 CVT. No end date is provided, so production after the stated start is not measured in the supplied data. There is no second generation to compare and no separate restyling listed. Consequently, choosing an S660 from this catalogue means comparing the two gearboxes within the same generation, rather than weighing different bodies, engines, power outputs, or generations against one another.
Honda S660 engine and specs
Both versions use the same 660 cc, 3-cylinder Gasoline engine with Turbo and Distributed injection (multi-point). The engine layout is Front, transverse, and both versions have RWD. Each produces 64 hp, equivalent to 47 kW, and 104 Nm.
The shared output works out to approximately 97 hp per litre. With a kerb weight of 830 kg, both versions carry approximately 13.0 kg per horsepower, or approximately 56.7 kW per tonne. These calculated ratios do not separate the versions because engine output and kerb weight are identical.
| Version | Power | Torque | Displacement | Fuel | Cylinders | Engine layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 0.7 MT | 64 hp / 47 kW | 104 Nm | 660 cc | Gasoline | 3 | Front, transverse | Turbo | Manual, 6 speeds | RWD |
| 0.7 CVT | 64 hp / 47 kW | 104 Nm | 660 cc | Gasoline | 3 | Front, transverse | Turbo | Variable; number of speeds not measured | RWD |
Power and torque engine speeds are not measured for either version. Cylinder arrangement, valves per cylinder, compression ratio, and bore and stroke are also not measured. Because those values are absent, they should not be used to distinguish the 0.7 MT from the 0.7 CVT.
Honda S660 performance and mpg
The 0.7 MT accelerates from 0 to 100 km/h in 12.6 seconds. The 0.7 CVT requires 13.4 seconds, making the Manual version 0.8 seconds quicker to 100 km/h. That is approximately a 6.0% shorter acceleration time than the Variable version.
Both versions have the same measured maximum speed of 140 km/h. The 0.7 MT therefore provides the better acceleration figure without changing the listed top speed.
| Version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption |
|---|---|---|---|---|---|
| 0.7 MT | 12.6 seconds | 140 km/h | not measured | not measured | not measured |
| 0.7 CVT | 13.4 seconds | 140 km/h | not measured | not measured | not measured |
Fuel consumption is not measured in city, highway, or combined driving for either version. An mpg comparison therefore cannot be made from the available data. Fuel type beyond the supplied Gasoline label is not measured, and CO₂ emissions and environmental class are not measured as well.
Honda S660 dimensions and weight
The supplied dimensions-related figures are identical for both versions. The 0.7 MT and 0.7 CVT each have a kerb weight of 830 kg and ground clearance of 125 mm. Gross weight is not measured, fuel-tank capacity is not measured, and wheel sizes are not measured.
| Version | Kerb weight | Gross weight | Ground clearance | Fuel tank | Wheel sizes |
|---|---|---|---|---|---|
| 0.7 MT | 830 kg | not measured | 125 mm | not measured | not measured |
| 0.7 CVT | 830 kg | not measured | 125 mm | not measured | not measured |
Both versions also share Independent, spring front suspension and Ventilated disc front brakes. Rear suspension and rear brake specifications are not measured. Since the recorded chassis, weight, and clearance figures do not differ, they provide no numerical reason to select one transmission over the other.
Honda S660 reliability and problems
Reliability records and problem reports are not measured in the supplied data. There is therefore no factual basis here for claiming that the 0.7 MT or 0.7 CVT is more reliable, less expensive to maintain, or more prone to a particular fault. Service intervals, repair costs, warranty details, and component durability are also not measured.
A reliability-led purchase decision should consequently remain separate from this specification comparison. The catalogue data supports a comparison of performance and transmission type, but not a judgment about long-term ownership risk.
Which Honda S660 version should you buy?
Choose the 0.7 MT if acceleration is the priority. Its 6-speed Manual gearbox accompanies a 12.6-second 0–100 km/h time, beating the 0.7 CVT by 0.8 seconds. It retains the same 64 hp, 104 Nm, 830 kg kerb weight, RWD, and 140 km/h maximum speed, so the quicker acceleration is the only measured performance advantage between the two versions.
Choose the 0.7 CVT if a Variable gearbox is the requirement. Its 13.4-second 0–100 km/h result is slower, but its listed engine output, torque, displacement, drive, kerb weight, clearance, and top speed match those of the 0.7 MT. The number of transmission speeds is not measured for the 0.7 CVT.
What extra money buys cannot be calculated because prices are not measured. Equipment levels, comfort features, safety systems, and options are also not measured, so they cannot justify a price difference from the supplied figures.
Based strictly on the available numbers, the 0.7 MT is the version to buy: it is 0.8 seconds quicker to 100 km/h while matching the 0.7 CVT in every other measured engine, weight, clearance, and top-speed figure. The 0.7 CVT makes sense when the buyer’s preference for a Variable gearbox matters more than the measured acceleration difference.
