1. Powertrain & Combustion Architecture
The Axia AV utilizes the naturally aspirated 1KR-VE 3-cylinder engine, engineered for high thermal efficiency and urban stop-and-go drivability.
- Engine Code: Toyota / Daihatsu 1KR-VE
- Cylinder Configuration: In-line 3-cylinder, transverse front-mounted
- Displacement: 998 cc (1.0 Litre)
- Bore × Stroke: 71.0 mm × 84.0 mm (Under-square / long-stroke geometry)
- Bore-to-Stroke Ratio: 0.85 (Optimized for low-end torque)
- Compression Ratio: 11.5:1
- Valvetrain: Double Overhead Camshaft (DOHC), 4 valves per cylinder (12 valves total), timing chain driven with Variable Valve Timing (VVT-i) on the intake camshaft
- Fuel Delivery: Multi-Point Electronic Fuel Injection (EFI)
- Cylinder Block / Head Material: Die-cast aluminum alloy block / Aluminum alloy head
- Maximum Power Output: 50 kW (68 PS / 67 bhp) @ 6,000 RPM
- Maximum Torque Output: 91 Nm (67.1 lb-ft) @ 4,400 RPM
- Specific Power Output: 50.1 kW/L (68.1 PS/L)
- Specific Torque Output: 91.18 Nm/L
2. Transmission & Driveline Kinematics
The D74A Axia AV features Daihatsu’s Dual-Mode Continuously Variable Transmission (D-CVT), which switches between a belt drive and a physical gear set.
- Transmission Type: Daihatsu D-CVT (Belt-driven CVT integrated with a planetary split-gear mechanism)
- Manufacturer: Akashi-Kikai / Daihatsu Motor Company
- Drivetrain Configuration: Front-Engine, Front-Wheel Drive (FF layout)
- Operating Logic:
- Belt Mode (Low-to-Mid Speeds): Traditional expanding/contracting pulleys provide infinitely variable ratios for smooth low-speed response.
- Gear Mode (High-Speed Cruise): At highway cruising speeds, a planetary gear set engages via a clutch pack to transfer drive mechanically, reducing friction losses and belt slip.
- Drive Mode Selector: Steering-mounted
PWR(Power) mode button (sharpens throttle response and holds higher virtual pulley ratios). - Start-Stop System: Perodua Eco Idle automatic engine stop/restart with dedicated auxiliary electrical circuit.
