Determining the best fuel consumption car in South Africa depends on verified, real‑world data – not marketing claims. Below is a factual overview based only on credible published figures and tests, focused on cars that have been sold in South Africa in recent years and are known for exceptionally low fuel consumption.
How “Best Fuel Consumption” Is Measured
Most manufacturers quote fuel consumption using standardised test cycles (NEDC, WLTP or similar), usually in litres per 100 km (L/100 km). Independent tests in South Africa often report their own real‑world results, which can differ from official figures but are useful for comparison.
Hybrid Leaders: Toyota Hybrid Range
Toyota Prius
The Toyota Prius has long been one of the most fuel‑efficient cars available globally, and it has been offered in South Africa in multiple generations.
- The UK’s Vehicle Certification Agency lists a 2019 Prius 1.8 hybrid with combined fuel consumption as low as 3.4–3.7 L/100 km, depending on specification, based on official test cycles

Although exact South African homologation data is not centrally published online, the Prius sold in South Africa has used the same 1.8‑litre hybrid drivetrain as in Europe and Japan, meaning its official consumption figures are in the same low range (around mid‑3 L/100 km). This places the Prius among the most fuel‑efficient petrol‑powered passenger cars ever officially sold here.
Toyota Corolla Hybrid
Toyota introduced hybrid versions of the Corolla sedan and hatch, and these have been praised in South African media for low fuel use.
- Toyota UK lists the Corolla 1.8 Hybrid with WLTP combined consumption from 4.4 to 4.7 L/100 km, depending on body and wheel size

The South African models share this 1.8 hybrid system, so their official figures are very similar. Local road tests have frequently reported real‑world averages in the 4–5 L/100 km range in mixed driving, which is extremely efficient for a family car.
Small Petrol Cars With Excellent Fuel Economy
Renault Kwid
The Renault Kwid is a budget city car that has been a strong seller in South Africa. It’s known for very low fuel consumption thanks to its small 1.0‑litre three‑cylinder engine and lightweight design.
- Renault India’s official brochure for the current Kwid 1.0 lists fuel consumption of 21.7 km/L, equivalent to roughly 4.6 L/100 km, on its certified test cycle
Source: https://www.renault.co.in/cars/renault-kwid/specifications.html
While this is based on the Indian certification cycle, the basic engine and platform are similar to those used in the South African market, placing the Kwid among the most economical non‑hybrid petrol cars in its class.
Suzuki Celerio
The Suzuki Celerio has been marketed in South Africa as a very frugal compact hatchback.
- Suzuki UK lists the 1.0 Dualjet Celerio with combined fuel use of 4.3–4.7 L/100 km under the NEDC‑correlated method, and around 4.7–4.8 L/100 km WLTP depending on spec
Source: https://cars.suzuki.co.uk/new-cars/celerio/specifications/
The South African Celerio uses the same 1.0‑litre three‑cylinder engine, so its official economy is in the low‑to‑mid 4 L/100 km band. That places it alongside the Kwid as one of the most fuel‑efficient small petrol cars available locally.
Suzuki Swift
The Suzuki Swift is another popular compact car in South Africa and is frequently highlighted for its light weight and thrifty engine.
- Suzuki Australia, using ADR‑based figures that are close to European WLTP numbers, quotes 4.6 L/100 km combined for the 1.2‑litre manual Swift GL

With similar hardware and tuning, the South African Swift delivers comparable official fuel economy, and local tests commonly find real‑world averages between about 5.0 and 5.5 L/100 km in mixed driving.
Diesel Options: Efficient Long‑Distance Cruisers
Diesel engines are typically more fuel‑efficient than equivalent petrol engines on the open road, which matters for South Africans who do long intercity trips.
Volkswagen Polo TDI / TDI BlueMotion (Historical)
Although newer generations have moved away from small diesels, earlier Volkswagen Polo TDI and especially Polo BlueMotion models that were sold in South Africa were extremely economical.
- VW UK’s historical data for the Polo BlueMotion 1.2 TDI quotes combined consumption of 3.4 L/100 km under the NEDC test

While this specific BlueMotion variant is no longer new in South Africa, it illustrates that some diesel superminis have been able to match or even beat hybrid fuel consumption in standardised tests.
Modern Small Turbodiesels (e.g. Peugeot, Citroën, VW 1.5 TDI)
Many small European diesels sold in South Africa share engines with their UK/EU counterparts. For example:
- Peugeot’s 1.5 BlueHDi engines in models like the 208 and 2008 are quoted in Europe with combined WLTP figures around 4.0–4.5 L/100 km, depending on model and specification
Source: https://www.peugeot.co.uk/showroom/208/specifications.html
Where these engines are used in South Africa, they are typically among the most fuel‑efficient choices for long‑distance commuters, often delivering real‑world numbers in the 4–5 L/100 km range on the open road.
Plug‑In Hybrids and Electric Vehicles
If you consider electricity as an energy source, some plug‑in hybrids (PHEVs) and battery‑electric vehicles (EVs) can beat any conventional car on energy per kilometre, though their running‑cost and “fuel consumption” metrics are different.
Toyota RAV4 Plug‑in Hybrid (International Benchmark)
The RAV4 Plug‑in Hybrid is not widely available in South Africa, but it’s useful as a benchmark of what plug‑in technology can do.
- Toyota Europe lists combined WLTP fuel consumption from 1.0 L/100 km (depending on wheel size and test conditions) thanks to its large battery and electric‑only range
Source: https://www.toyota-europe.com/new-cars/rav4-plugin-hybrid/specs-and-tech
This figure is highly dependent on charging habits and daily distance, and it shows why PHEVs can appear to have extremely low “fuel” use on paper.
Battery‑Electric Vehicles
EVs such as the Nissan Leaf and BMW i3, which have been sold in South Africa in limited numbers, don’t use petrol or diesel at all, so their efficiency is measured in kWh/100 km instead of L/100 km.
- The Nissan Leaf’s official consumption in Europe is around 17–20 kWh/100 km WLTP depending on generation and battery size

If your primary goal is to reduce spending on liquid fuel entirely and you have suitable charging access, EVs can effectively deliver zero litres per 100 km of fuel use.
Why There Is No Single “Best Fuel Consumption Car” for Everyone
Because test methods, body styles, driving conditions and availability change over time, it’s impossible to name one absolute “best fuel consumption car in South Africa” that suits every driver. However, based on credible official data from comparable markets and known South African model line‑ups, the following groups consistently rank among the top for low fuel use:
- Hybrid leaders
- Toyota Prius – around 3.4–3.7 L/100 km combined on official test cycles

How to Choose the Most Economical Car for Your Needs
When comparing for yourself in South Africa:
- Check the official fuel consumption label on the specific model and engine you’re considering, expressed in L/100 km.
- Look for independent road tests from reputable motoring publications that include long‑term fuel figures for South African conditions.
- Match the drivetrain to your driving:
- City‑heavy use: hybrids and small petrols (e.g. Prius, Corolla Hybrid, Kwid, Celerio) perform best.
- Long‑distance highway driving: small diesels (e.g. 1.5‑litre turbodiesels) can be exceptionally efficient.
- Consider total cost of ownership, including fuel, servicing, tyres, insurance and potential battery or diesel‑system maintenance over the life of the car.
For South African buyers focused purely on low fuel consumption from currently and recently available mainstream models, Toyota’s hybrids (Prius and Corolla Hybrid) and small city cars like the Renault Kwid and Suzuki Celerio stand out in credible, published data as some of the best in their respective segments.
