The actual fuel consumption of the Mercedes-Benz S450 is approximately 10-12L/100km. Here are the relevant details about the Mercedes-Benz S450: 1. Powertrain: The Mercedes-Benz S450 is equipped with a 3.0T V6 twin-turbocharged engine, delivering a maximum power of 245kW (333PS)/5250rpm and a peak torque of 480Nm/1600-4000rpm, paired with a 7-speed automatic transmission. 2. Body Dimensions: For the short-wheelbase version, the vehicle measures 5116×1899×1483mm in length/width/height, with a wheelbase of 3035mm, while the long-wheelbase version has a body length of 5246mm and a wheelbase of 3165mm.

I've been driving a Mercedes-Benz S450 for over half a year, mostly for urban commuting. According to my fuel consumption records using Xiaoxiong Youhao app, the average is around 11.5L/100km. During rush hour traffic jams, it can spike to 14L, while on highways it stays stable at just over 9L. The 3.0T engine with 48V mild hybrid system does help with fuel efficiency, but the electric motor assistance is limited in traffic jams. Using AC increases fuel consumption by about 1L, and aggressive acceleration/braking also affects the data. Compared to the official claimed 8.9L/100km, my real-world figures being slightly higher is normal. I recommend using 98 octane fuel for better combustion efficiency. Overall, this is quite reasonable for a D-segment luxury sedan.

Do I need to be present for the first car maintenance?

It is not necessary for the car owner to be present for the first car maintenance. Car brands usually offer the first maintenance for free. You just need to drive the car and bring the vehicle license, purchase invoice, first free maintenance card, maintenance manual, and driver's license. The vehicle license must be carried, as the staff will establish a vehicle file based on the information in the vehicle license. If you encounter traffic police during the drive, you will also need to provide the vehicle license to avoid unnecessary trouble. The first maintenance refers to the initial service after the new car has been driven. The timing of the first maintenance varies by car, typically after driving 1,000 to 3,000 kilometers. Completing the first maintenance indicates that the vehicle's break-in period has ended, and it can now be driven at the standard load and normal speed specified for the vehicle.
