Whats the difference between the BMW 650 and the 650i?

My question is not only about the 650 model, i want to know the difference between a BMW with an " i " in its model name and the BMW without the " i "|||BMW 650i exists and the 650 does not.





BMWs follow a certain nomenclature in the naming of many of their vehicles; a 3 digit number is followed by 1 or 2 letters. The first number is the series number. The next two numbers traditionally represent the engine displacement in cubic centimeters divided by 100.





The system of letters is:





* d = diesel


* i = fuel-injected


* x = all wheel drive


* L = long wheel base


* C = coupe (no longer used)


* T = touring (wagon/estate)


* t = hatchback


* g = biogas


* s = sport package (typically includes front sports seats, spoiler, aerodynamic body kit, upgraded rims, etc.)


* e = eta (essentially "economy" in English)


* es = eta sport


* cs = sport coupe (a combination seen on early highend coupes like the E9, E24, and special Motorsport variants of the E31)





For example, a BMW 760Li is a fuel-injected 7 Series with a long wheel base and 6.0 litres of displacement.





However, there are exceptions. The 2007 BMW 328i is a 3 Series that has a 3.0 litre engine. The 2007 BMW 335i also has a 3.0 litre engine; however, it is twin-turbocharged, which is not identified by the nomenclature.





The 'L' signifies special luxury variants. Most notable being the L7 (most famous of which are E23 and E38 based) and L6 (E24 based). They traditionally featured extended leather as well as special interior appointments.





The 'M' - for Motorsport - identifies the high-performance M vehicle of a particular series (e.g. M3, M5, M6, etc). For example, the M6 is the highest performing vehicle in the 6 Series lineup. Although 'M' cars should be separated into their respective series platforms, it is very common to see 'M' cars grouped together as its own series.





The 'Z' identifies a two seater roadster (e.g. Z1, Z3, Z4, etc). M variants of Z models have the M as a suffix or prefix, depending on country of sale. (e.g. 'Z4 M' / 'M Roadster' in Canada)





A capitalized 'X' may supersede the series number (e.g. X3 and X5) which refers to the Sports Activity Vehicle (SAV) lineup, all of which feature BMW's xDrive.





Both X %26amp; Z vehicles will have 'i' or 'si' follow the engine displacement denoted in litres. The 'si' (e.g. X3 3.0si) identifies the vehicle as being equipped with the 'sport package' %26amp; is 'fuel-injected'. X %26amp; Z vehicles only denoting 'i' (e.g. X3 3.0i) identifies the vehicle as 'fuel-injected' and no sport package.





Also, station-wagons/estates are traditionally given the "Touring" or "Sport Wagon" tagline, depending on country of sale.|||650i means its "injected" which slightly boosts power from an engine and improves performace |||One has an "i" and the other one doesn't.|||My grandmother has a 2007 650i, when we went to the BMW dealer they told us that the 'i' meant injected. Basically they told us it has more power (which she likes)


Hope this helps.|||there is no just 650.





All BMW's are i, xi, or ci.


325i


330ci


330xi


645i


650i


530i


545xi





i is the base version of the car(the cheapest version with RWD)


xi is the All wheel drive version of the car, which is also more expensive.


ci is the convertible version of the car.





650 means it is a BMW 6 series with a 5.0L engine.


325 means it is a BMW 3 series with a 2.5L engine.


545 means it is a BMW 5 series with a 4.5L engine.
