I did not realize til after I bought my Volvo S40 T5 that the 5 cylinder engine design included a girdle as shown below. With the twin overhead cams and 4 valves per cylinder, they were pretty advanced for their time (mine is a 2005)

Honda engines are similar, this is the S2000 engine when I was mid rebuild, think it's fairly common for anything relatively high revving.

They even have steel inserts cast into the aluminium ladder for local stiffness around the bearings.

Ladder frames have become more common. Many of our UK Fords have had them since the 1990's petrol & the small diesels too.

And it’s Terry for the win. He is absolutely correct.
