A true LSD will be available in the upcoming BMW M235i (Limited Slip Differential).
The 2014 M235i is one of the most exciting BMWs to go on sale next year, claims AutoExpress, which quotes Klaus Froehlich, Senior Vice President Brand and Product Strategies BMW Group. The “M2” is currently regarded as doubtful, although the M235i is expected to surprise some BMW buyers.
“I have just approved the M Sport performance kit for the M235i, which will come with an actual limited slip differential. I’m still deciding whether to include this as a choice on all models. As a spiritual successor to the 2002ti, the M235i comes the closest. It is faster than the BMW 1M Coupe around the Nurburgring, which was my initial benchmark.
The 3.0 liter TwinPower turbocharged six-cylinder engine found in the M135i, which generates 320 horsepower and 450 Nm of torque (332 lb-ft) at 1,300 rpm, will most likely power the M235i. Redline has been adjusted to 7000 revs.
The M235i will be offered in the 2 Series lineup in an xDrive configuration, following in the footsteps of the BMW M135i.

The item is incompatible with your BMW!
For drivers who want their F22 M235i/M240i coupe to have more acceleration and grip, this modification is fantastic!
Your M235i/differential M240i’s modification increases performance over the original factory specifications. Limited-slip differentials were only available on M versions, leaving the car with just electronic traction control to control wheel spin. When both rear wheels are gaining the most traction, the F22 becomes a more capable performance vehicle. Torque is swiftly and flawlessly transferred from a spinning tire to the tire on the opposing side using a limited-slip differential. A M Performance differential transfers 30% of torque to the opposing tire (and then electronic traction control steps in). The technology operates independently and prevents traction control, which will reduce power or use the brakes, from interfering. Because there is more traction and grip, the automobile seems faster. This M Performance differential is a Genuine BMW component that can be easily and directly swapped for your existing differential. It also has the same warranty and maintenance obligations as any other BMW differential.
This M235i/M240i differential has a 3.08 gear ratio and is used in M240i with manual gearbox as well as M235i/M235xi with automatic or manual transmission. While AWD xDrive models must stick with their original factory axle ratios, other RWD models can use this ratio to increase acceleration.
Is there a limited slip differential on the BMW M4?
I came upon something that almost seems too wonderful to be true while perusing the 2014 M3 and M4 models’ new features. It appears that the new vehicles will employ a unique limited-slip differential with a 100% lockup capability.
Even among supercars, few are equipped with such features, making this an exceptional achievement. However, the press release states plainly that “the degree of lock – which may be anywhere between 0 and 100% – is altered as required within a fraction of a second.”
The M3 and M4 are truly shaping up to meet the greatest of expectations, if this proves out to be true and not simply some sort of marketing ploy.
Along with the LSD, the cars will also gain access to the DSC’s M Dynamic Mode subfunction, which enables reckless driving in total safety. When you want more wheel slip and drifting ease, the system intervenes, allowing you to do so, but it also serves to keep you in check if you go too far (unless you deactivate it completely).
Is there a limited slip differential on a BMW?
Most motorsports cars have significantly more power than the typical LSD can manage, which leads to inadequate traction and power transmission. Due to this, the majority of BMW race cars have a clutch-pack limited slip differential. More traction, improved vehicle control, and more efficient use of the vehicle’s power are all benefits of using an LSD.
If my BMW has a limited slip differential, how can I know?
By jacking up the vehicle and spinning one of the rear tires, you may quickly determine if you have an open differential. You have an open differential if the other wheel spins the other way. Your vehicle has a limited slip differential, or LSD, if it spins in the same direction.
Is there a limited slip differential on the BMW xDrive?
All 7-series sedans have what is effectively a pseudo-limited-slip rear differential, and the xDrive also works with it.
Is there a limited slip differential on the M240i?
Now that the mechanical details are out of the way, how do these automobiles feel to drive?
After a few days in an Audi R8 Spyder, I immediately drove the M240i, which gave me a good opportunity to “clear” my automotive palette with something completely unrelated to the M2. Even after a burst of ferocious V10 power, the M240i feels incredibly responsive.
The mid-range has a ton of power, so you hardly ever need to crank the engine all the way up. It has a little different sound from its N55-powered predecessor, but it still doesn’t have a particularly pleasing six-pot.
The M240i is a highly capable and enjoyable B road weapon, but depending on the circumstances, you get the impression that it is occasionally pushing the limits of what its more basic chassis can handle. The lack of a limited-slip differential makes it uncomfortable when you lose control in the back (this is one-tire-fire territory, lads), which will happen rather frequently due to the ample amount of midrange torque. Additionally, the brakes need to be strengthened.
As soon as I was back in the M2, I realized that the improvements mentioned above resulted in an entirely new vehicle. With a sharper turn-in and significantly less body roll, you achieve the kind of confidence in the corners that the M240i simply cannot provide. It is significantly more stable when you push past the limit because of a correctly adjusted limited-slip differential and has a lot more manageable attitude. The open rear diff on the M240i is truly its weak point, so if you decide to purchase one of these, you should definitely consider the optional (at dealer pricing) PS2500 LSD.
It’s difficult to judge performance because the M240i actually seems faster because of the robust torque delivery. However, the older N55 from the M2 is considerably more pleasurable to use because it is quicker and more responsive. The M2 is much happier being pushed to the rev limiter than the M240i, where you rarely find yourself changing above 6000rpm.
Is there a restricted slip diff on the M340i?
the classic sports sedan from BMW in its seventh generation. New design, suspension, engine, and technology generations. 369 lb-ft of torque and 382 horsepower. standard limited-slip differential for M Sport
Is there a limited slip differential on the M4?
Can we have more fun by activating M Dynamic Mode (MDM) while DSC traction is at step 0?
No. You are driving in DSC OFF mode when using M Traction Control, which means that you will have sole control over the vehicle. Additional braking intervention is used by MDM as part of the DSC to further stabilize the vehicle.
There is no M Traction Control setting that is equivalent to MDM because M Traction Control and MDM are different functionalities. M Traction Control, to put it simply, is a slide control system that, when DSC is turned off, manages rear wheel slip in 10 phases. Wheel spin is permitted at any time at Level 0, which is OFF. There is virtually little room for slide at the higher levels. The engine’s rpm is the only factor used to regulate slip. Yaw rate of the vehicle is not being regulated here. MDM is a component of the DSC process and actively regulates the vehicle’s yaw rate, in contrast to M Traction Control. To stabilize the vehicle dynamics on the road, DSC/MDM employs braking interventions as well as engine power adjustments. Depending on the yaw rate behavior, MDM applies M Traction Control levels 4 to 7.
A restricted slip differential with electronic control is used in every new BMW M3 and M4 model.
Undoubtedly, an electronically controlled limited slip differential is used in every new BMW M3 and M4 car. For more information on the rear differential, see episode 16.
Yes, MDM is a standard feature for all M models, even those with manual transmissions.
In general, M Traction Control is an optional feature that comes with the M Drive Professional (option code 1MB), which is standard in some areas. Please consult the information from your nearby dealer.
Which automobiles include limited slip differentials?
The Challenger and Charger from SRT are more powerful versions of the corresponding ordinary Dodge cars. They differ from the ordinary variants in their aggressive design, larger wheels and tires, firmer springs, and more power, obviously. The 6.4-liter, 392 cubic inch (thus the name) engine in the SRT392 generates 485 horsepower, 110 more than the typical V8. The 707 horsepower Hellcat variants are also available if you require nearly twice as much power as the standard V8.
On the less potent versions of these cars, limited slip differentials can be difficult to find, while Getrag mechanical torque-sensing systems are standard on the SRT models. The Getrag unit is ideal for utilizing all of that Hemi power since it has a torque ratio of 1.8, which means it can deliver 1.8 times more power to the wheel with traction than to the wheel without grip.
What unique features does the M3 possess?
The redesigned rear differential is one of the most crucial components of the performance of the new BMW M3 and M4. Over the past few years, BMW has made significant advancements to its electronically controlled limited-slip rear diffs, and as a result, this new BMW M3 diff is the greatest one yet. We get to see how it functions and how crucial it is to the car’s performance in this brand-new BMW M film.
BMW’s new rear differential, which has two alternative final drive ratios—3.15 for automatic transmissions and 3.46 for manual transmissions—is the greatest the firm has ever produced. Additionally, it is electrically regulated for the quickest and most accurate reaction. It also contributes to maximum traction coming out of corners, which improves the M3’s handling ability. The BMW M3 and M4 can launch so effectively despite only having rear-wheel drive at the moment thanks in part to the diff.
With a description of its components, this new video demonstrates how it operates. Additionally, it demonstrates where it is situated, how it is positioned beneath the BMW M3, how it is intended to reduce cabin noise, and even how its output shafts function.
We don’t have enough time in the new BMW M3 or M4 yet, but we want to test the new rear diff shortly. To gauge how much better it is over the previous generation vehicle, we’d also like to contrast it with the F80 BMW M3. Even so, I do recall how much better the rear differential of the F80 M3 Competition Package was than the original. I therefore have high hopes for the rear differential of this new M3 and its capacity to transfer all of its enormous power to the ground.
What is a rear differential on a BMW?
The component in your BMW that divides the engine’s torque between the left and right wheels is known as the rear differential. Both wheels will be able to spin at various rates when the torque is divided between them. When turning, your BMW will need the rear wheels to spin at various rates. In a left-hand turn, for instance, the right rear wheel will need to move forward more quickly than the left because of the greater distance covered. In order to guarantee that the wheels have the appropriate quantities of torque, the rear differential is in charge. The computerized sensors that monitor the rear differential in a recent BMW will decide how much torque is necessary.
