cars - power bulge on/in the bonnet

[nyota]

If I'd like to use the words 'bonnet' and 'power bulge' together, which preposition should I go for: power bulge in the bonnet or on the bonnet?

Google gives a similar number of results for both.

Under a subtle power bulge in the bonnet is a mighty V8 engine tuned by the AMG engineers to pump out 457bhp giving the car a blistering 0 to 60 time of 4.4 seconds with its top speed limited to 156mph.

Thanks Bennevis.

Here autocar.co.uk, on the other hand, it's 'in'. Perhaps it doesn't make much difference.

A power bulge in the bonnet is more than a little unnecessary on a 134bhp hybrid.

In my example, it's "in" as well. Go with it.

Gosh, I know how to argue my case
I meant to find an example with 'on'. Here it comes:

From the outside, it looks much like the previous model, although if you get your magnifying glass out, you'll spot a power bulge on the bonnet. Topgear

In your second example, the verb "spot" justifies the use of the preposition "on" (spot it where? - on the hood), but, in general, since the bulge is part and parcel of the hood, I do find "in" perfectly appropriate to use in that collocation.

Never use those phrases with North Americans. They'll laugh at you.

Do tell
Is it just the 'bonnet'?

America and England are two nations divided by a common language. (Who said that?)

Everyone says it!

Yeah, "power bulge" is pretty laughable.
