Comments

The diesel-engined Mercedes GLC performs exceptionally well in this part of the assessment and leaves only a little room for improvement for emissions in cold engine start scenarios. Common past issues of the Diesel like NOx or particle emissions are no problem for Mercedes' latest generation of exhaust gas aftertreatment. The extremely low level of particle emissions is perhaps what impresses most. However, the lower results in the other two parts of the assessment prevented the vehicle from advancing to Green NCAP's additional robustness tests, and leave open the questions about its -7°C performance.

The turbo-charged diesel engine requires 5.2 l/100 km in the Warm and Cold lab tests. With 5 l/100 km, the best consumption is reached in the real-world On-Road Drive. The worst value is measured in the Highway Test – 7.3 l/100 km. The GLC makes a good use of the traditionally high efficiency of the diesel powertrain and benefits from its mild-hybrid system. Given that it is a heavy combustion engine SUV, it scores well in this part of the assessment.

Comments

In both the Warm and Cold standard WLTC tests, the measured CO2 emissions are below the officially declared value. In these tests, 25 g CO2‑eq./km well-to-tank emissions related to the fuel production and supply are added to the 137 g CO2/km at the tailpipe and result in scores of about 4 out of 10 points. In the Highway Test, the total CO2-eq exceeds Green NCAP's limits with 227 g/km CO2‑eq. While the methane (CH4) output is controlled very well, the GLC has increased laughing gas (N2O) emissions in every lab test.

Our verdict

The Mercedes-Benz GLC 220d tested here is a mild-hybrid SUV with a turbo-charged 2‑litre diesel engine. The 48-volt mild-hybrid system helps the 2 tonne car bring down CO2 emissions, but not enough to reach Green NCAP's additional robustness testing. The consumption values are a tribute to the efficient diesel engine and help the car strive for a creditable rating. In the Greenhouse Gas Index, valuable points are lost due to the non-regulated laughing gas (N2O) emissions. The GLC performs most impressively in the Clean Air part of the assessment, demonstrating extremely efficient control of both gaseous and particle emissions, the latter being at ambient air concentration levels and amongst the lowest ever seen by Green NCAP. Overall, the Mercedes-Benz GLC receives an average score of 55% and collects well deserved 3 Green stars.
