1. Powertrain & Combustion Architecture

All variants across the D27A Alza range utilize the naturally aspirated 1.5-litre 2NR-VE 4-cylinder engine, tuned with Dual VVT-i and an Eco Idle start-stop system to maximize fuel efficiency while carrying 7 occupants.

  [Dual VVT-i] ──► 16V DOHC Pentroof Head (11.5:1 CR) ──► 78 kW (106 PS) @ 6,000 RPM
  [Multi-Point]──► 72.5 mm × 90.6 mm (Long-Stroke)   ──► 138 Nm @ 4,200 RPM

• Engine Code: Toyota / Daihatsu 2NR-VE
• Cylinder Configuration: In-line 4-cylinder, transverse front-mounted
• Displacement: 1,496 cc (1.50 Litres)
• Bore x Stroke: 72.5 mm x 90.6 mm (Long-stroke / under-square geometry)
• Bore-to-Stroke Ratio: 0.80 (Optimized for low-to-mid-range torque response)
• Compression Ratio: 11.5:1
• Valvetrain: Double Overhead Camshaft (DOHC), 4 valves per cylinder (16 valves total), timing chain driven with Dual VVT-i (continuous variable timing on intake and exhaust camshafts)
• Fuel Delivery: Multi-Point Electronic Fuel Injection (EFI)
• Block / Head Material: High-pressure die-cast aluminum alloy block and cylinder head
• Maximum Power Output: 78 kW (106 PS / 105 bhp) @ 6,000 RPM
• Maximum Torque Output: 138 Nm (101.8 lb-ft) @ 4,200 RPM
• Specific Power Output: 52.14 kW/L (70.85 PS/L)
• Specific Torque Output: 92.24 Nm/L
• Start-Stop System: Perodua Eco Idle automatic idling stop system standard across all trims

2. Transmission & Driveline Kinematics

The D27A Alza pairs the 1.5L powerplant exclusively with Daihatsu’s Dual-Mode Continuously Variable Transmission (D-CVT), replacing the previous generation’s 4-speed torque converter.

• 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)
• Dual-Mode Operating Logic:
  • Belt Mode (Low-to-Mid Speeds): Traditional expanding/contracting pulleys provide smooth step-off acceleration and continuous variable ratio adjustment for urban commuting.
  • Split-Gear Mode (High-Speed Cruise): At sustained highway speeds, a planetary gear set engages via a clutch pack to transfer drive mechanically, reducing high-RPM belt slip and cutting thermal/parasitic friction losses.
• Manual Shifting: Gated shift lever with manual sequential mode (+ / – virtual steps).
• Drive Mode Selector (H & AV variants): Steering-mounted switch offering 3 operational modes: Eco, Normal, and Power (PWR).

3. Chassis, Suspension & Braking Dynamics

Built on the DNGA-B modular architecture, the Alza sits significantly lower than conventional ruggedized MPVs, prioritizing car-like dynamics, a low center of gravity, and high torsional rigidity.
