There’s a piece of foam insulation under the engine cover that makes it sound slightly more metallic and clicky. Otherwise, they are quite noisy in general at idle.
EDIT just realised you are taking about a new car not an old one. Ignore that.
Re the service intervals – long life service is variable and governed by measuring oil temp and engine load, so if you do lots of long motorway miles it approaches 18k miles before it reminds you. Lots of town or aggressive driving and it will be much less than 10k miles. It needs special oil too for this.
You can switch the service reminders back to annual and 10k miles of you want.
