Whats the difference between the BMW series 1 through 7?

Just wondering what the difference between the BMW series are, is it that a series 7 is better than a series 1, and what sort of difference are we talking about?

Whats the difference between the BMW series 1 through 7?norten

1 Series = smallest + cheapest

3 Series = smaller + more expensive

5 Series = midsize + even more expensive

and so on...

1 Series: Sub-compact hatchback which is currently sold only in Europe. It's a tiny little commuter car with your base BMW features. It's also pretty low on luxury. Cheapest BMW to purchase.

3 Series: Compact-Midsize sedan. BMW's bread-and-butter vehicle. Awesome handling, four doors and is a competitor with the Lexus IS, Acura TL, Audi A4 and Infiniti G35, among others. Turbocharged engine that makes 300 hp is an option. Price starts reasonably in the mid-30s but gets really high with all those options like navigation and sport package.

5 Series: Midsize sedan which is competitor to Merc E-Class, Audi A6, Infiniti M and Lexus GS. This is for people who want BMW handling + functionality. Base engines puts out 215 hp, but more expensive models like the 550i make 360 hp. Luxurious interior, but once again, is extremely pricey if you add those options.

6 Series: Full-size luxury coupe or convertible, starts in the mid-70s for the coupe and low-80s for the convertible. Navigation and all those creature comforts are standard as well as a 360 hp engine. Is a competitor to Merc CLK and SL, Lexus SC and Cadillac XLR.
