The 220d is the cheapest of the new diesel engines in the new GLC coupe line up, (relacing the old 2.2 litre unit) and it's a popular choice having already seen widespread use throughout the rest of the Mercedes range. It's a 2.0 litre 4 cylinder turbo motor that generates 177 horsepower and 400Nm of torque, good for a 0-60 time of just over 8 seconds and a top speed of 134mph. It's good for a towing capacity of 2500kg and is the biggest seller in the GLC range due to both the affordability and the flexibility of the engine. It's mated to an automatic gearbox as standard (no manual is available) and also has 4Matic 4 wheel drive as standard, so traction isn't an issue.
