Chassis and engine classifications

[ALBundy]

Ever talked to somebody about BMWs? Of course you have. If you tell him/her you've got a 5 series he/she may ask what type. Then it dawns on you, 5 series could mean FOUR different types of BMW! An original late 70's model, the revised 81-87 car, the radically new 88-96 car or a brand spanking new 97 model. Now imagine you need to order a part from BMW. Clearly asking for a front bumper for a 5 series isn't going to get you far. Neither will the year as a 1996 5 series could be one of two models. What we need is a model code for both the car and the engine. People on the BMW digest also use these codes frequently to avoid confusing between models so knowing them is useful.If anyone finds errors or omissions please tell me. Eventually a dedicated page will appear for each model and engine, sleep is for wimps!Car Model DesignationsModel Year Cars 114 / E6E10 / E12 67 - 77 1502, 1600, 1602, 1800, 1802, 2000, 2002ti/tiiE10 was the touring three door modelE20 was the 2002 tii & turbo E3 68 - 77 2500, 2800, Bavaria, 3.0S/Si, 3.3Li E9 65- 75 2000CS, 2500CS, 2800CS, 3.0CS/i/L E12 72- 81 518, 518i, 520, 520i, 535, 525i, 528i, 530i, M535i E21 75-83 316, 318i, 320, 320i/s, 323i E23 78-87 725i, 728, 728i, 730i, 732i, 733i, 735i, 745i, L7 E24 77-89 628i, 630CS/i, 633CSi, 635CSi, M635CSi, L6 (highline) E26 78-81 M1 E28 82-88 518i, 520i, 524td, 525i/e, 528e, 533i, 535i, M535i, M5 E30 83-91 316, 316i, 318i/s, 320i, 323i, 324td, 325e, 325i/ix/is, M3 E31 90 on 840i, 840Ci, 850i, 850Ci, 850CSi E32 88-94 730i, 735i/iL, 740i/iL, 750iL E34 88-96 518i, 520i, 525i/x, 525td/s, 530i, 535i, 540i, M5 Z1 (E30) 89-91 Z1 convertible Z3 (E36/7) 96 on Z3 convertible and Z3 coupe (Z5) E36 91 - 99 316i, 318i/s/ti/tds, 320i, 323i, 325i/td/tds, 328i/s, M3,Z3 E38 95 - 2002 728i, 730i, 730d, 735i, 740i/iL, 750i/L E39 97 on New 5 series 520i, 523i, 525tds, 528i, 530d, 535i, 540i, M5 E46 late 98 Next 3 series E53 2000 X5 four wheel drive SAV E52 2000 Z8 roadster E60 2002?

Engine DesignationsNot all engines are available in all markets. For example, smaller engines tend not to be available in the US. Diesel engines were not available in the UK until fairly recently. Power figures are for european models, most older US engines tend to be restricted by emissions regulations.BMW Code Size(litres) Cyl Valvesper Cyl Power (bhp@rpm) Torque (lb/ft@rpm) BHP/litre Torque/litre Manufactured Bore x Stroke(mm) Timing Weight(kg) VANOS Used in Notes & Comments M10 1.5 1.6 1.8 2.0 2.0i 2.0tii 2.0 turbo 4 2 75 @ ? 85 @ 570090->98 @ 5250100 @ 5500125 @ 5700130 @ 5800170 @ 5800 ? 91@ 3000108 @ 3000116 @ 3000129 @ 4350131 @ 4500181 @ 4000 50 53.152.25062.56585 ? 56.96058656590.5 75 66 -> 69?71 -> 8768 -> 75E21 320i / E12 520i71 -> 7573 -> 74 82x71 84x7189x7189x8089x8089x8089x80?

VANOS = variable valve timing.To convert from ft/lb to Nm multiply by 1.36 (100ft/lb = 136Nm).To convert from BHP to kW multiply by 0.735 (100 bhp = 73.35kW).Engine weights are for a dry engine with no manifolds, starter motor, alternator, etc. They will vary by 2 or 3 kg for different types of fuel injection and model year. US M50 had an iron block due to sulphur problems and is much heavier than euro. Anti-pollution kit will add a few kgs to earlier US spec engines.

Hahahhahaha damn long .... LONGEST POST AWARD Bro i think we have to classify according to model .. easier viewed ..cheers

saved from the old forum:M Series Engine SpecBy chanklI believed we discussed the specs of the M50/M50TU/M52/M52TU/M54 before but the 3 series forum has been pruned so all those info was lost. I just spent a bit of time reviewing the TIS (again) and compiled the following specifications information on the M5x engines. The number in hp are U.S number which typically is 1 or 2 hp less than what the other part of the world uses. I try to stay close to the CKD model so some specific model like E46 325Ci or E38 or E53 are not listed. Well, let see how long can these spec info survived in this forum.The M50 engine was first introduced in 1990 in the E34 525i replacing the M20 engine. In 1993, the M50TU replaced the M50 engine in the E35 525i and E36 325i. In this spec, the maximum torque arrive at a lower rpm compared to the M50 engine.M50B20 110KW/6000rpm, 190Nm/4700rpmM50B20TU 110Kw/5900rpm, 190Nm/4200rpmM50B25 141KW(188hp)/5900rpm, 245Nm(181lb.ft)/4700rpmM50B25TU 141KW(188hp)/5900rpm, 245Nm(181lb.ft)/4200rpm (E36)M50B25TU 141KW(189hp)/5900rpm, 250Nm(184lb.ft)/4200rpm (E34)The TU stands for Technical Update, which offer a new Engine Conrol System (DME 3.3.1) and the introduction of Variable Camshaft Control (through VANOS) which gave improved torque curve, lower fuel emissions, better idle quality, and lower fuel consumption as compared to the M50 engine.M52B20 110KW/5900rpm, 190Nm/4200rpmM52B25 125KW/5500rpm, 245Nm/3950rpmM52B28 142KW(190hp)/5300rpm, 280Nm(207lb.ft)/3950rpmThe M52B28 engine was available on the E36 328i and E39 528i in CKD form. The earlier batch of M52 engine incorporate a cast iron cylinder block while the later batch was make of alunimium silicone alloy. (I found out recently that the earlier batch of 328i use the same cylinder head as the M50TU. The different is in the number of holes for cooling has increased. There are other differences in the cam design and hydraulic lifters but I wouldn't go into details. Now I know why we don't hear M52 engine overheat that often). Engine control is via the Siemens MS41.1 system.When the E46 was launch in 1999, the M52TU engine was introduced in E46 323i, E46 328i and the E39 528i. The major changes in this Technical Update is the redesigned crankcase, modified pistons, Double VANOS for the camshaft drive, and Siemens MS42 DME syste. Later the E39 523i was introduced with the M52B25TU engine.M52B25TU 126KW(170hp)/5500rpm, 245NM(181lb-ft)/3500rpmM52B28TU 144KW(193hp)/5500rpm, 280Nm(206lb-ft)/3500rpmIn 2000/2001, the M54 engine replaced the M52B2xTU engine. These are available in the E46 320i, 325i and 330i, E39 525i and E39 530i. Interesting to note is that the E36/7 Z3 2.5 and Z3 3.0 also uses the M54 engine!M54B22 125KW(170hp)/?, 245Nm(181lb-ft)/?M54B25 141Kw(189hp)/6000rpm, 244Nm(180lb.ft)/3500-4750rpmM54B30 170KW(228hp)/5900rpm, 298Nm(220lb.ft)/3500-4750rpmNoticed the range of rpm for the torque. I remember 3er mentioned something on the infinite variable camshaft control. I have yet to dig up more on that.The development objectives of the M54 engine were to reduce emission and fuel consumption levels while maintaining power and performance compared to the M52TU six cylinder engines. In the M54B30 engine, the changes include shorter skirt pistons, forged crankshaft, higher lift camshaft, shorter ram tubes intake manifold, slightly large injection valves. On the M54B25 engine, most of the features in the M52 engine were carried over. New on the M54 engine is the use of Siemens MS43.0 engine management system which is an electronic throttle control system adopted from the ME7.2 system on the M62 engne.It is tough going through all the spec! The version I had don't have a complete picture yet. Anyone want to do some home work on the M4x or M6x series engine spec?

The M54 specs look like UK specs.. Anyone know the diff between the UK specs and German/Asia spec M54s which make up the power difference. Heard that we've also tested out the power differences between Marco's ride (UK spec) and JPB/Chester's car (CKD).
