ADAC Ecotest 2024 is an annual study conducted by the German automobile association, ADAC, which evaluates vehicle efficiency under real driving conditions. It has become a European benchmark, assessing a wide range of factors that influence fuel consumption and CO2 emissions of a vehicle.

The latest study, recently published by this organisation, includes evaluations of a total of 84 models.

Electric cars clearly dominate the ADAC Ecotest in 2024. However, some combustion engines remain competitive, with the efficiency of a diesel model also highlighted.

The top eight positions in the ADAC Ecotest 2024 ranking are exclusively occupied by fully electric vehicles, all awarded a five-star rating. ADAC does not consider electric cars as zero-emission vehicles, taking into account the CO2 and pollutant levels that arise during electricity generation.

The Peugeot e-208 and its "big brother," the e-308, lead the Ecotest 2024 evaluation with a total of 105 points. Their low consumption of 16.0 kWh per 100 kilometres (including charging losses) translates to only 80 grams of CO2 per kilometre. The electric Opel Corsa follows closely with a total of 103 points, thus securing third place. A third Peugeot in this test, the e-2008, equipped with the same engine, ranks first among SUVs and sixth overall. These Peugeots also offer some of the best range in their class: 410 km for the e-208, 413 km for the e-308, and 406 km for the e-2008 (WLTP combined cycle).

Hot on the heels of the Stellantis models is the Tesla Model 3. The mid-size sedan ranks fourth in the standings. The Tesla is the largest vehicle in the top category and consumes 17.2 kWh/100 km in the test. Its CO2 emissions are 86 grams, giving the Model 3 an overall rating of 100 points. The fifth position goes to the Opel Astra Electric Sports Tourer with 115 points and 87 grams of CO2.

With the Prius, Toyota demonstrates how efficient combustion engine cars can be in their plug-in hybrid variant. The Japanese model is the only gasoline engine vehicle to secure a spot among the top ten tested in 2024. When driven with a fully charged battery, it consumes 11.5 kWh of electricity and 1.7 litres of gasoline in the first 100 kilometres. This results in a CO2 balance of 104 grams per kilometre. Once the battery is depleted, the test engineers measured a fuel consumption of 4.8 litres.

As the best diesel, the VW Passat Variant 2.0 TDI reached 38th place with a four-star rating, highlighting its consumption of 5.0 litres of diesel per 100 kilometres. According to the study's authors, this model demonstrates "how clean modern diesel engines are now." In the pollutants chapter, VW achieves the maximum number of points thanks to its exhaust gas purification system.

To conduct this evaluation, ADAC measures fuel consumption in city, highway, and mixed cycles. Tests are conducted under real driving conditions to measure fuel consumption in different scenarios. The vehicle's acceleration and recovery capacity, as well as its throttle response, are also evaluated.

To carry out these tests, ADAC uses a precise and standardised methodology that ensures the comparability of results.

ADAC Ecotest Stages:

    Imagen principal - Vehicle Selection:

    Vehicle Selection:

A wide range of vehicles is selected, from compact cars to SUVs and electric vehicles, to ensure a comprehensive representation of the market.

  1. 2

    Imagen principal - Vehicle Preparation:

    Vehicle Preparation:

Before the tests, vehicles are prepared according to the manufacturer's specifications and filled with the recommended type of fuel.

  1. 3

    Imagen principal - Driving Cycles:

    Driving Cycles:

Vehicles undergo a series of driving cycles that simulate different real-world situations, such as city, highway, and motorway driving. These cycles are designed to reflect the average driving habits of drivers.

    Imagen principal - Fuel Consumption Measurement:

    Fuel Consumption Measurement:

During the driving cycles, fuel or electric energy consumption is precisely measured, depending on the type of vehicle.

  1. 5

    Imagen principal - Emissions Analysis:

    Emissions Analysis:

In addition to fuel consumption, CO2 and other pollutant emissions are measured. Other factors that may influence efficiency, such as aerodynamics, vehicle weight, and technology used, are evaluated.

The results of the ADAC Ecotest 2024 confirm the trend towards the electrification of the automotive fleet. Electric vehicles are becoming increasingly efficient and offer a more pleasant driving experience. However, they also highlight the importance of continuing to improve the efficiency of internal combustion vehicles to reduce their environmental impact.
