The Honda R06A is a 660 cc (0.66 L) inline-three cylinder gasoline engine. Introduced around 2013 to succeed the P07A engine, the R06A is currently utilized across Honda’s "Kei" vehicle lineup in Japan, including the N-Box, N-WGN, N-One, and the S660 sports car.

: Regular oil changes every 5,000 km are critical, especially for turbocharged variants.
Paired with Suzuki's Smart Hybrid Vehicle system (SHVS). It uses an Integrated Starter Generator (ISG) and a small lithium-ion battery to assist the engine during acceleration and recapture energy during braking. Crucial Maintenance Specs (From the Factory Manual) r06a engine manual pdf
The R06A is designed for maximum thermal efficiency in a compact footprint. Specification Inline 3-cylinder, DOHC 12-valve Displacement 658.2 cc (40.2 cu in) Bore x Stroke 64.0 mm x 68.2 mm Valvetrain DOHC with VVT (Intake and Exhaust on NA models) Drive System Timing Chain Block/Head Material Compression Ratio 11.0–11.5:1 (Naturally Aspirated); 9.1:1 (Turbocharged) Key Technical Features
Many people try to use a K6A manual for the R06A. This is a dangerous gamble. While the mounting points may look similar, the timing chain guide design, oil pump specifications, and torque sequences changed significantly.
Unlike its predecessor, the R06A uses a low-friction timing chain designed to last the lifetime of the engine. However, if replacement is required due to oil starvation or stretching, follow this alignment workflow: The Honda R06A is a 660 cc (0
Misfires and poor idle are often due to dirty VVT screens. The manual shows how to test the solenoid resistance (typically 6-8 Ohms at 20°C) and the correct cleaning solvent to avoid damaging the seals.
Tightened in a multi-step sequence. Generally involves an initial torque phase (approx. 20-25 Nm), followed by specific angle turns (e.g., 60 degrees, then another 60 degrees) to properly stretch the torque-to-yield bolts.
Oil drains completely out of the VVT sprocket due to a worn internal locking pin or using an oil filter lacking an anti-drainback valve. Paired with Suzuki's Smart Hybrid Vehicle system (SHVS)
: For the most accurate vehicle-specific data, the Maruti Suzuki Owner's Manual portal provides digital copies that include basic maintenance schedules for the R06A used in the Wagon R.
