The fuel economy of the 2023 Mercedes-Benz GLC in the Malaysian market varies depending on the powertrain configuration. The GLC 200 model is equipped with a 2.0-litre turbocharged engine, with a combined fuel consumption of approximately 6.6 litres per 100 kilometres. The 4MATIC version of the GLC 300, due to its all-wheel-drive system, has a slightly increased fuel consumption to around 7.0 litres per 100 kilometres. The actual fuel consumption may be affected by factors such as driving habits, road conditions, and the use of the air - conditioning. It's worth noting that the 2023 Mercedes - Benz GLC features a 48V mild - hybrid system, which can recover kinetic energy during start - up and coasting, further optimizing fuel efficiency. For Malaysian consumers, the tropical climate and congested urban road conditions may cause the fuel consumption to be slightly higher than the official figures. Luxury SUVs in the same class, such as the BMW X3 or Audi Q5, also offer similar mild - hybrid technologies. However, the specific fuel economy performance needs to be compared through actual test drives. When making a choice, factors such as after - sales service and local adaptation should also be considered.
