- Mercedes-Benz CLA EQ 250+ achieved the highest Green NCAP score with a 91% rating.
- MG HS recorded the lowest sustainability performance with lifecycle emissions exceeding 303 g CO2/km.
Green NCAP conducted a new round of environmental assessments on June 18, evaluating vehicles across electric, hybrid, and gasoline powertrain categories to measure their sustainability performance. The latest assessment covered four models: Mercedes-Benz CLA EQ 250+, Toyota C-HR, MG Motor HS, and MINI Cooper C. The program analyzes efficiency, emissions, and lifecycle environmental impact, with smaller and lighter electric vehicles generally delivering the strongest sustainability outcomes.
Green NCAP Sustainability Results Overview
The evaluation highlighted significant differences between electric and conventional vehicles in terms of efficiency and lifecycle emissions. The Mercedes-Benz CLA EQ 250+ secured the highest rating among the tested models, while the MG HS recorded the weakest environmental performance. Hybrid and gasoline-powered vehicles achieved intermediate results, reflecting varying levels of fuel efficiency and carbon impact across different vehicle architectures.
Green NCAP Ratings and Performance Comparison
The following table summarizes the key findings from the latest Green NCAP vehicle assessment.
| Vehicle Model | Rating | Score | Lifecycle Emissions |
|---|---|---|---|
| Mercedes-Benz CLA EQ 250+ | 5 Star | 91% | 119 g CO2/km |
| Toyota C-HR | 3.5 Star | 66% | 196 g CO2/km |
| MINI Cooper C | 3 Star | 52% | 230 g CO2/km |
| MG HS | 1.5 Star | 26% | 303.7 g CO2/km |
Mercedes-Benz CLA EQ 250+ Achieves Top Sustainability Score
The Mercedes-Benz CLA EQ 250+ emerged as the best-performing vehicle in the assessment, earning a 5-star rating and an overall score of 91%. Its strong performance was supported by a long driving range, rapid charging capability, low operational emissions, and efficient energy consumption. The vehicle offers a range of up to 690 km and records official energy consumption of 12.2 kWh/100 km. During testing with air-conditioning enabled, energy use remained efficient at approximately 13.9 kWh/100 km. Its estimated lifecycle emissions stand at around 119 g CO2 per kilometer.
Toyota C-HR Delivers Competitive Hybrid Efficiency
The Toyota C-HR secured a 3.5-star rating with a total score of 66%. The model demonstrated efficient fuel consumption, averaging 4.4 l/100 km on mixed-road conditions and 3.6 l/100 km in urban driving. Lifecycle emissions were measured at approximately 196 g CO2 per kilometer. While this performance is strong for a gasoline-powered vehicle, its overall environmental footprint remains higher than that of leading electric vehicle benchmarks such as the New Grecale, New GranTurismo, and New GranCabrio EV models.
MINI Cooper C Records Mid-Level Sustainability Performance
The MINI Cooper C, equipped with a 1.5-liter three-cylinder turbocharged gasoline engine, achieved a 3-star sustainability rating and a score of 52%. The vehicle delivered moderate fuel economy ranging between 6 and 7 liters per 100 kilometers. However, its lifecycle emissions reached approximately 230 g CO2 per kilometer, limiting its overall sustainability performance compared with more efficient hybrid and electric alternatives.
MG HS Receives Lowest Environmental Rating
The MG HS, powered by a 1.5T GDI engine, produced the weakest results among the tested vehicles. The model received a 1.5-star rating and an overall score of 26%. Highway fuel consumption reached as high as 9.9 l/100 km, while the vehicle failed to earn points in both efficiency and emissions categories. Its lifecycle emissions were calculated at approximately 303.7 g CO2 per kilometer, exceeding the benchmark threshold and resulting in the lowest sustainability ranking in the assessment.
Frequently Asked Questions
Which vehicle achieved the highest Green NCAP sustainability rating in the latest assessment?
The Mercedes-Benz CLA EQ 250+ achieved the highest Green NCAP sustainability rating with a 5-star score of 91%. The electric vehicle demonstrated excellent efficiency, low lifecycle emissions, strong range capability, and effective energy management during testing. It recorded official energy consumption of 12.2 kWh/100 km and lifecycle emissions of approximately 119 g CO2 per kilometer, making it the strongest performer among the four vehicles evaluated by Green NCAP.
Why did the MG HS receive the lowest sustainability score?
The MG HS received the lowest sustainability rating because of its high fuel consumption and elevated lifecycle emissions. The vehicle earned only a 1.5-star rating with a score of 26% after recording highway fuel consumption of up to 9.9 l/100 km. It also scored zero in efficiency and emissions categories. Lifecycle emissions reached approximately 303.7 g CO2 per kilometer, significantly exceeding the environmental performance levels achieved by the other tested vehicles.
