Engine Displacement | Heavy-duty trucks (Hilux/Fortuner) | 5.0L (4941–5038cc) ▲▲▲ vs Industry Standard 2.4L, ▲▲ vs Our Base 2.5L | ▲▲▲ 50% higher torque for towing/loads; meets ISO 3095 durability | Higher fuel consumption (30% more than 2.5L) |
| Light-duty trucks (Hiace) | 2.5L (2458–2500cc) ▲ vs Industry Standard 2.2L | ▲ 15% better fuel efficiency (18 MPG vs 16 MPG) | Lower power output (150HP vs 250HP for 5.0L) |
Fuel Efficiency | Long-distance driving | 2.5L: 18 MPG ▲ vs Industry Standard 16 MPG | ▲ 12% lower fuel costs for daily commutes | 5.0L only achieves 14 MPG due to higher power demand |
Torque Output | Off-road/Heavy Load Transport | 5.0L: 450 Nm ▲▲▲ vs Industry Standard 320 Nm | ▲▲▲ 40% more torque for rugged terrain and heavy payloads | Requires reinforced transmission (additional cost) |
Compatibility | Toyota-specific repairs | Direct fit for Hiace/Hilux/Fortuner (no adapters) | ▲▲ Plug-and-play installation for listed models | Limited to Toyota vehicles (not universal) |
Engine Condition | Budget upgrades | Used (TAI AUTO PARTS) ▲ vs New engines (40% cost savings) | ▲ 40% lower cost vs new engines; tested for 50+ hours | Requires pre-purchase inspection for wear (e.g., cylinder block integrity) |
Emissions Compliance | Urban/Regulated environments | EPA Tier 4 ▲▲ vs Industry Standard Tier 3 | ▲▲ 20% lower NOx emissions (meets EU Stage V norms) | Older models may lack DPF (Diesel Particulate Filter) |
Noise Level | Residential zones | 43 dBA (idle) ▲ vs Industry Standard 50 dBA | ▲ Quieter than refrigerator hum (ISO 3095 compliant) | Noisier under full throttle (65 dBA vs 60 dBA for newer engines) |
Cost & Maintenance | Fleet management | Used engines: $2,500–$3,500 ▲ vs New ($6,000+) | ▲▲ 58% cost savings; warranty available (12 months) | Higher long-term maintenance costs (e.g., valve replacement) |
