A 30-year-old Mercedes-Benz W140, equipped with a six-cylinder diesel engine, is subjected to intense acceleration on the Autobahn, a German highway, which is not a good idea for such an old car.
In a video published on YouTube by the channel TopSpeedGermany, the vehicle, a 1994 S 350, manages to reach a top speed of 185 km/h, but this only happens on a downhill stretch after a long acceleration run. Even so, the engine shows resilience, running until the end of the run despite clear signs of stress.
During the acceleration, the temperature gauge steadily rises and hits its limit when smoke begins to emerge from the engine compartment. At the moment the smoke appears, the driver eases off the acceleration, and the coolant warning light turns on on the dashboard.

Although the smoke appears to be steam, suggesting a failure that could be simple, such as a damaged coolant hose, the condition of the engine after the run raises concerns about more serious damage.
The experience serves as a warning for drivers of old cars: it is crucial to monitor gauges during high accelerations on unrestricted highways. The pursuit of speed can have severe consequences, especially in vehicles that were not designed to withstand such pressures.
