1. Powertrain & Combustion Architecture

The All-New Saga swaps out the old iron-block CamPro engine for Geely-derived aluminum 1.5-litre i-GT (BHE15PFI / BHE15-CFN) technology. It runs on an efficiency-focused Atkinson combustion cycle with a low-maintenance silent timing chain and dual variable valve timing (DVVT).

• Engine Code: BHE15PFI / BHE15-CFN (i-GT NA)
• Cylinder Configuration: In-line 4-cylinder, transverse front-mounted
• Displacement: 1,499 cc (1.5 Litres)
• Bore x Stroke: 73.4 mm x 88.57 mm (Under-square / long-stroke geometry)
• Valvetrain: Double Overhead Camshaft (DOHC), 16 valves, silent timing chain with Dual Variable Valve Timing (DVVT)
• Combustion Cycle: Atkinson Cycle (optimised thermal efficiency and reduced pumping losses)
• Fuel Delivery: Port Fuel Injection (PFI / Multi-Point)
• Ancillaries & NVH: Electric water pump, dual-mass flywheel (cuts vibration by up to 25%)
• Maximum Power Output: 88 kW (120 PS / 118 bhp) @ 6,100 RPM
• Maximum Torque Output: 150 Nm (110.6 lb-ft) @ 4,000 – 5,000 RPM
• Specific Power Output: 80.05 PS/L (58.7 kW/L)
• Specific Torque Output: 100.06 Nm/L

2. Transmission & Driveline Kinematics

Proton deploys a dual-transmission strategy across the 1.5L range:

• Drivetrain Layout: Front-Engine, Front-Wheel Drive (FF)
• Aisin 4-Speed Automatic (Standard & Executive):
  • Proven 4-speed torque-converter automatic (4AT) with electronic lock-up clutch for robust durability and linear stepping shifts.
• Punch Powertrain CVT (Premium Flagship):
  • Steel-belt continuously variable transmission calibrated with an Atkinson-cycle ECU map, delivering the lowest fuel consumption in the lineup (4.9 L/100 km).

3. Chassis, Suspension & Braking Dynamics

The AMA platform replaces the previous hydraulic steering system with Electric Power Steering (EPS).
