Imagine a whole planet already driving more fuel efficient cars then bmw.

What do you mean be „too much”? Today sportcars is 500-600 horsepower and more, my F Type S with its 380 hp is an entry level sportscar and nothing more. And no, you can not have a sportcar with a 1.8 engine.

Why do i want exhaust in sportcar? Emm, its like asking why i want a burger with meat. Because its how it is made?

I had 335i before and it’s fuel consumption is great for it’s power.

That was predictible :)

I need at least 3 liter 400+ horsepower engine with good exhaust in an entry level sportcar, not a joke 1.5l mini cooper engine dude.

Coolest car ever with a 1.5l engine? Do you drive cars or only sit inside lol?

Well you just got the top secret - you can get an M3 for only 300 USD remap. Thats how it works/s
