All production years 2021–Present meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/5684).
The Honda U24A is a 2,356 cc inline‑four turbocharged petrol engine engineered for high-performance hatchbacks (2021-Present). It combines direct injection with VTEC and a single-scroll turbocharger to deliver a broad, flat torque curve. Designed to meet Euro 6d standards, it balances aggressive performance with stringent emissions compliance.

The Honda U24A is used exclusively in Honda's FL5 platform with transverse mounting. This engine was developed specifically for the Civic Type R and features unique components-reinforced engine mounts, a larger intercooler, and a bespoke exhaust-not found on other Honda engines. No licensing to other manufacturers has been documented. All adaptations are documented in OEM technical bulletins.
The U24A's primary reliability risk is thermal stress under sustained high-load conditions, with incidence highest in track-driven FL5 Type Rs. Honda internal service data indicates that adherence to cooldown procedures and the 0W-20 specification is critical. Sustained high-RPM operation and infrequent oil checks make adherence to the 10,000 km service intervals non-negotiable for long-term health.

The most common questions about engine codes, what they mean, how to find them and how this database works
The U24A is a new engine, but its design is based on proven Honda architecture. Its main potential weakness is thermal stress under extreme track use. With strict adherence to cooldown procedures, oil changes (using 0W-20), and avoiding prolonged abuse, it is expected to be very reliable long-term, following Honda's performance engine heritage.
As a new engine, widespread issues are not yet documented. Potential concerns based on early service bulletins include turbo heat soak under track conditions, GPF clogging from insufficient highway driving, HPFP failures, and carbon buildup on intake valves. These are being monitored by Honda.
The U24A is currently used exclusively in the eleventh-generation Honda Civic Type R (FL5, 2021-Present). It is the successor to the K20C1 engine and was developed specifically for this high-performance model.
Yes, the U24A responds very well to tuning. A simple ECU remap can safely yield 300+ PS. More extensive modifications (downpipe, intercooler, injectors) can push it to 400+ PS. The stock internals are strong, but supporting mods, high-quality fuel (RON 98), and oil are essential for reliability, especially with increased power.
In the FL5 Civic Type R, expect 28-34 mpg (UK) combined under normal driving. Fuel economy drops significantly with aggressive driving or track use. The GPF and turbocharger also make it less efficient than naturally aspirated engines. Using higher octane fuel (RON 98) as recommended does not significantly impact economy.
Yes. The U24A is an interference engine. If the timing chain were to fail (a rare occurrence), the pistons would collide with the open valves, causing catastrophic internal engine damage. The chain is very durable with proper maintenance.
Honda strongly recommends 0W-20 synthetic oil for optimal performance and protection, especially for the VTEC system and turbocharger. This is non-negotiable for warranty and reliability. Using a different viscosity can lead to increased wear and potential engine damage.
