" …am not comparing VW Golf to any car…just feeling the diesel engine may not be well protected (and diesels run for a long while ) "
Consider this. Although engines are very tough in a collison, engine accessories can be replaced and even engine blocks, too.
Engine placement figures into the overall crash worthiness of the vehicle and the important part of the car to protect in a collision is the passengers, not the metal and plastic. Would you rather have a well protected engine in your lap following a collision ?
I’d concern myself with the safety of the vehicle for the draiver and passengers. Let the Insurance company worry about repairing plastic and metal. Also, you can check and see what the insurance companies think of the vheicle, collision and repair cost-wise, as well as medical payouts on the IIHS site.
It’s just a car. Don’t worry so much about it. They’re fixable and replaceable. Your health, not so much.
I’m just curious, do you drive by the “Braille Method” or have a history of crashing into cars and objects ?
