Petrol vs Diesel vs Electric Cars in Kenya: True Cost of Driving (2026)
With petrol above KES 214 and diesel above KES 232 a litre in 2026, the cost of driving in Kenya has changed — and diesel is now pricier than petrol. We compare petrol, diesel and electric on real cost per kilometre and total ownership.
Something quietly flipped in Kenya in 2026: diesel is now more expensive per litre than petrol, reversing decades of the opposite. With petrol above KES 214 and diesel above KES 232 a litre, the “buy diesel to save fuel” rule no longer holds for everyone — and electric is suddenly the cheapest way to drive by a wide margin. Here is the real cost comparison per kilometre and over a year.
Cost per 100 km: the real comparison
| Vehicle | Consumption | Cost per 100 km |
|---|---|---|
| Petrol sedan (12 km/L) | 8.3 L | ≈ KES 1,785 |
| Diesel SUV (14 km/L) | 7.1 L | ≈ KES 1,663 |
| Efficient petrol (16 km/L) | 6.25 L | ≈ KES 1,340 |
| Electric (15 kWh/100 km) | 15 kWh | ≈ KES 230 |
Petrol vs diesel: which now?
With diesel pricier per litre but diesel engines 25–30% more efficient, diesel still wins on cost-per-km for long-distance and heavy vehicles. For ordinary city commuting in a small car, petrol is now often cheaper overall — especially once you factor in diesel’s higher servicing costs. The old “always buy diesel” advice is outdated for 2026.
Is an electric car worth it in Kenya?
On running cost, it is no contest — EVs are ~85% cheaper per kilometre and have far fewer moving parts to service. The barriers are upfront price and charging access outside Nairobi. But for a city commuter who can charge at home, the fuel saving alone can offset a chunk of the higher purchase price within a few years.

The 2026 fuel landscape rewrote the rules: petrol now often beats diesel for everyday city driving, and electric beats everything on running cost.
