Why L/100 km is the better unit
L/100 km is a consumption metric (lower is better). MPG is an economy metric (higher is better). The two scale differently: a 5 MPG improvement at 15 MPG saves three times as much fuel per kilometre as a 5 MPG improvement at 35 MPG. L/100 km flattens that out — every 1 L/100 km reduction is the same amount of fuel saved.
Real-world vs EnerGuide
Natural Resources Canada’s EnerGuide labels reflect the five-cycle laboratory test (city, highway, AC, cold-temperature, high-speed). Real-world Canadian driving consistently shows 10–25% higher consumption, particularly in winter. Cold engines, AWD systems, winter tires, snow drag, idling at red lights with the heater on — none of those are in the lab cycle.
Common Canadian benchmarks
- Compact sedan (Civic, Corolla, Elantra) — 6.5–7.5 L/100 km combined.
- Compact crossover (CR-V, RAV4, Tucson) — 7.5–9 L/100 km combined.
- Mid-size SUV (Highlander, Pilot, Telluride) — 9–11 L/100 km combined.
- Full-size pickup (F-150, Silverado, RAM 1500) — 11–14 L/100 km combined.
- Hybrid sedan (Camry Hybrid, Prius) — 4.5–5.5 L/100 km combined.
- Hybrid SUV (RAV4 Hybrid, CR-V Hybrid) — 6–7 L/100 km combined.
Driving habits with the strongest leverage
Speed is the biggest lever — at 120 km/h you burn 20–30% more fuel than at 100 km/h, all else equal. Aggressive acceleration / hard braking adds 15–30%. Cold starts hammer urban consumption: a five- minute trip costs proportionally far more than a 30-minute trip. Roof boxes, bike racks and trailers hit drag exponentially with speed. Tire pressure matters more than people think — a tire down 7 PSI from spec costs roughly 3–5% in fuel economy.
