BMW stopped using truly limited-slip differentials with the advent of the E9X and E60 platforms. The advantages between an open and limited-slip differential are seconds on the track and a massive increase in corner exit grip.

What diff is on an E46 M3?
However, all E46 M3’s have the standard 3.62 ratio. Luckily, BMW Motorsport came up with a different final drive gear sets for their racing program which happen to fit inside the E46 M3’s ‘Large Case 210 Diff’.
What differential does the M3 have?
The new rear differential of the BMW M3 and M4 is the brand’s best one yet and comes with two different final drive ratios; 3.15 for automatic transmissions and 3.46 for manual transmissions.
How much oil does a e46 Diff take?
Using a good fluid pump, fill the differential with 75W-90 synthetic gear lubricant until it overflows out of the fill hole. The differential will take approximately 1.5 quarts to fill.
What is an M sport differential?
The M Differential It compensates for different rotational speeds of the rear wheels, particularly on curves. The inner curve wheel covers less distance than the outer curve wheel, meaning the outer wheel turns faster when cornering.
How does a Torsen diff work?
Does BMW have differential lock?
wheel. This fundamental difference is set off by the axle differential. large difference in frictional coefficients on the drive wheels.
What year E46 is best?
- VANOS Oil Pump.
- VANOS Solenoid.
- Camshaft Sprocket Bolts.
- Exhaust Camshaft Hub.
Why is the E46 so good?
It had a high-revving inline-6 engine, and lightweight construction, capturing the essence of the iconic BMW M3 E30. Since then, people considered the E46 generation as the greatest M car built due to its simplicity, appeal, and just overall design of it all.
Is E46 M3 fast?
Fresh from the dyno, the M3 claimed the title of “Fastest BMW” with a speed of 178mph.
How much oil does a BMW differential take?
BMW sells 500ml bottles of fluid, and the differential takes roughly 1-1.2L. The bottles are around $60 a piece, so you’ll need at least two bottles to fill the diff.
What does M Sport Package include?
The package is available on many BMW models and usually includes features such as larger wheels with performance tires, unique exterior trim, an M steering wheel or M sport steering wheel with paddle shifters, an aerodynamic kit, and sport seats.
What is 3 Series M Sport package?
What is an active differential?
Active Differential: Very similar to a limited slip differential, the active differential still employs mechanisms to provide the resistance needed to transfer torque from one side to another – but rather than relying on purely mechanical force, these clutches can be electronically activated.
Why is Torsen differential disadvantages?
The main disadvantage of the Torsen differential is when no torque is sensed on one of the axles, the differential does not lock. Torsen differential is not capable of transferring 100% of torque to one of the axles.
What cars use Torsen differential?
- Audi Quattro (1987-current)
- Audi 80 & 90, Audi S2, Audi RS2 Avant.
- Audi 100 / Audi 200 / Audi 5000.
- Audi Coupé quattro.

- Audi A7, Audi S7, Audi RS7.
Who invented the Torsen differential?
Torsen Torque-Sensing is a type of limited-slip differential used in automobiles. It was invented by American Vernon Gleasman and manufactured by the Gleason Corporation. Torsen is a portmanteau of Torque-Sensing.
What is BMW electronic differential lock?
Electronic Differential Lock (EDL) is a limited slip differential imitation – this is an electronic system that detects wheelspin via ABS sensors and applies brakes to spinning wheels. This results in the torque being transferred via open differentials to another wheel that has more traction.
What is active M?
The Active M differential takes into account so-called pre-steering components, which means that it not only responds to an event but actually sets the locking torque even before an event occurs. This results in enhanced transparency in terms of vehicle behaviour and also in better controllability.
What differential does a M4 have?
The BMW F82 & F83 M4 is manufactured with a friction welded ring gear and an electronically locking plate differential.
How much horsepower does a E46 have?
The BMW M3 E46 generation left the BMW factory in Regensburg with 333 hp and 268 lb-ft of torque.

What motor is in the E46 M3?
The 3.2-litre S54B32 engine built on the legacy of its predecessor. Nevertheless, it was an almost entirely new development. It is regarded as the pioneer of BMW’s now well-established high-rev concept, where its only time for the next gear at just under 8,000 revolutions.
Why are E46 M3 so expensive?
The BMW E46 M3’s all-round excellence and increasing scarcity have led to high prices. The BMW E46 M3’s timelessness means finding one to call your own takes a considerable amount of money, especially for models in pristine condition. The magic of this car is that it can be many things to many drivers.
Is the E46 a classic?
