What transmission does a Honda Civic SI have?

The Honda Civic Si uses a six-speed manual transmission. There is no automatic option for the Si in the current generation.

In the latest (11th-generation) Civic lineup that began with model year 2020, the Si remains a manual-only variant, pairing its turbocharged 1.5-liter engine with a six-speed manual gearbox to emphasize driver engagement and sporty performance. This setup stands in contrast to other Civic trims, which offer automatic transmissions in various markets.

Transmission basics for the Civic Si

Here are the core facts about the Si's gearbox and how it affects driving dynamics.

• Transmission type: 6-speed manual (6MT)


• Drive configuration: front-wheel drive with the manual gearbox


• Availability: exclusive to the Civic Si; automatic transmission is not offered for this trim in current generations

With a standard six-speed manual, drivers control gear selection and rev matching themselves, delivering a traditional sports-car character that fans expect from the Si line.

Context and market variations

While the 6MT is the standard across North American and most markets for the Civic Si, Honda has occasionally tweaked engineering details across model years. The Si remains a performance-focused variant that prioritizes engagement over automatic convenience, unlike other Civic trims which offer automatic options or CVTs. If you’re shopping in a market outside North America, verify local drivetrain options, as there can be regional differences.

Summary

The Honda Civic Si is equipped with a six-speed manual transmission. There is no automatic option in the current generation, reflecting the model’s focus on driver involvement and sport performance.

Which is better, SI or type R?

The Type R is better for ultimate performance, while the Si is the better all-around value for a sporty daily driver. The Type R has significantly more power, a superior chassis and suspension, and more aggressive performance features, but costs more and is less fuel-efficient. The Si is a more affordable option that is still fun to drive, but lacks the Type R's extreme performance capabilities.
 
Honda Civic Type R

• Performance: Has more power, better suspension, and superior handling, making it a superior performer. It is considered a top-tier front-wheel drive car, especially for track use. 
• Cost: More expensive to buy, which can be a significant factor. 
• Efficiency: Less fuel-efficient due to its higher power output. 
• Features: Has more driving modes and a wider track with a longer wheelbase for better performance. 
• Body style: Available as a hatchback, which offers more cargo space. 

Honda Civic Si

• Performance: A fun and sporty car, but significantly less powerful than the Type R. 
• Cost: A much more affordable option, providing excellent value. 
• Efficiency: More fuel-efficient. 
• Features: Available as a sedan, which is a practical choice for a daily driver. 
• Modifications: A popular choice for enthusiasts who plan to modify their cars. 

Which one should you choose?

• Choose the Type R if: Your budget allows for it and you prioritize maximum performance for track days or spirited driving. 
• Choose the Si if: You want a fun, sporty car that is also practical, fuel-efficient, and more affordable.

Does Honda still use CVT transmissions?

Yes, Honda continues to use continuously variable transmissions (CVT) in many of its models for their fuel efficiency and smooth operation. You can find CVTs in vehicles like the Civic, CR-V, and Accord, as well as their hybrid variants. Honda has improved its CVT technology over time to address previous concerns about reliability.
 
How CVTs work in Honda vehicles

• A CVT doesn't have fixed gears like a traditional automatic. Instead, it uses a pulley system to provide a seamless range of gear ratios.
• This system allows the engine to operate at its most efficient RPM, which leads to better fuel economy.
• The lack of distinct "shifts" results in a smoother driving experience that some drivers prefer. 

Common Honda models with CVTs
Civic Sedan and Hatchback (including Hybrid), Accord and Accord Hybrid, CR-V and CR-V Hybrid, HR-V, and Prologue. 
Considerations

• While Honda's CVTs are considered reliable, especially in newer models, they still require regular maintenance, such as fluid changes, to ensure longevity. 
• Some drivers may not enjoy the driving feel of a CVT, which can sometimes feel different from a traditional transmission. 

What's so special about Civic Si?

The Honda Civic Si is powered by a 1.5-liter turbocharged inline-four engine. This engine produces 200 horsepower and 192 lb-ft of torque, giving it a solid balance of power and handling. The turbocharged setup provides strong mid-range torque, making the Si feel quick and responsive on the road.
