RNB44 replied to our post on Twitter with this question:
Is the engine OK on Lewis' car after pushing after Vettel in the latter stages of the race? If so, how can you test it? And would it be used in future on non-power tracks like Monaco / Singapore as a precaution?
AS: "You may have heard us on the radio telling Lewis his engine was getting hot. That is just the fact that when the cars get so close, you don't get clean air going into the radiators to keep it cool. It did get quite close to limit temperate but we are monitoring these limits very closely.
"You can run up to the limits, you just have to be careful you don't run over them. In Lewis' case we were OK and just up around the limit. You heard Lewis say on the radio he couldn't get past and he was going to save the engine.
"At that point, he just backed off, was cooling the car and could turn down the power of the engine so it was not having to work so hard. But, we are pretty confident the engine will be in good shape.
"We are limited in what tests we can do because we can't actually run the engine, we are not allowed to until we get to Bahrain.
"In terms of where it will be used next, at the moment that's Lewis' only engine in the engine pool, so he is going to be running that engine in Bahrain and China. We will be monitoring them as we always do to ensure everything continues to be OK."
