Smile engine temperature

Hi,

I would like to ask about the engine temperature.
My car is a 2015 year's A250. The normal engine temperature is around 90C.
And the warm up time is normal, it usually takes less than 10 minutes to achieve 90c (outside environment temperature is 20c).
When I drive in city, the engine temperature can maintain at 90C. And while i drive in highway (speed around 80km/hr to 110km/hr). The engine temperature can maintain at 90c.
But when the speed goes up to 120km/hr above, the engine temperature drops to 80C or even slightly below 80C.
Just want to know is it normal? Or should it has a problem on the thermostat?

Thanks for your answer in advance.

Welcome to the forum, izzyyuen

80-100C is normal operating temperature and is within MB spec. And yes, the temp gets lower to about 80C on speeds over 60 mph.

You own a great little Mercedes, btw, what's your location?
