For years, many drivers believed that automatic cars consumed more fuel than manual ones. That used to be true, but modern technology has changed the scenario completely. Today, automatic transmissions — especially CVTs, dual-clutch gearboxes and optimized torque-converter automatics — can achieve fuel consumption equal to or even lower than many manual versions.
Among the models available in the Portuguese market, several stand out as exceptionally efficient, offering the best fuel economy with an automatic transmission. These are the top contenders.
1. Toyota Yaris Hybrid — the most fuel-efficient automatic car in Portugal
When it comes to real-world efficiency, the Toyota Yaris Hybrid is consistently at the top.
Its hybrid system uses an e-CVT automatic transmission designed for maximum efficiency, often delivering consumption below 4 L/100 km.
Why is it so efficient?
- highly reliable and mature hybrid system
- small petrol engine combined with an electric motor
- automatic transmission that keeps engine revs low
- exceptional performance in city driving where the electric mode operates frequently
For anyone looking to minimize fuel costs, it is difficult to find a better option.
2. Toyota Corolla Hybrid — comfort, space and low consumption
The Toyota Corolla Hybrid follows the same philosophy as the Yaris but offers more space and power.
Even as a larger car, it maintains impressively low consumption for an automatic model.
Highlights:
- efficient e-CVT automatic gearbox
- very smooth operation
- consistently low fuel consumption
- excellent reliability record
It is ideal for drivers who want outstanding economy without sacrificing comfort.
3. Honda Jazz Hybrid — consistent efficiency
The Honda Jazz Hybrid is another highly rational choice, combining a compact design with an efficient automatic transmission.
Strengths:
- excellent consumption in urban conditions
- smooth automatic operation
- well-calibrated hybrid system
- surprisingly spacious interior
It is particularly suitable for city drivers who spend a lot of time in traffic.
4. Renault Clio E-Tech Hybrid — the efficient French alternative
The Renault Clio E-Tech Hybrid uses an innovative multi-mode automatic transmission inspired by Formula 1 technology.
The result is a compact car that offers comfort and remarkable fuel efficiency.
Advantages:
- intelligent and efficient automatic gearbox
- smooth driving feel
- balanced consumption even on motorways
It is a strong choice for those who want an economical automatic without leaving the small-car segment.
5. Toyota C-HR Hybrid — the fuel-efficient automatic SUV
For drivers who need a crossover or SUV, the Toyota C-HR Hybrid is one of the most fuel-efficient automatic options on the market.
Reasons:
- extremely efficient hybrid system
- responsive and lightweight e-CVT
- surprisingly low fuel consumption for an SUV
It is an excellent choice for families or drivers who prefer a higher driving position while keeping fuel costs low.
So, which automatic car is the most economical?
Considering real-world fuel consumption, technology, reliability and long-term ownership cost, the leader is:
Toyota Yaris Hybrid
It consistently ranks as the most fuel-efficient automatic car in Portugal, with consumption figures lower than almost all competitors and very low maintenance expenses.
The idea that automatic cars consume more fuel than manuals no longer reflects reality.
Modern automatics — especially hybrids — have become the true champions of efficiency, making them the smartest choice for drivers who want comfort and fuel savings at the same time.
