The phrase
"axle differential" refers to a device in a vehicle that helps distribute power between the wheels. It allows the wheels on the same axle to turn at different speeds, which is important when taking turns or driving on uneven surfaces.
Full definition
In the interest of balance axle load distribution, it is located at the end of the prop shaft, in front of the
rear axle differential.
The rear
axle differential also has a new specially reinforced mount to improve the NVH (noise, vibration, harshness) characteristics.

axle differential provides a perfect alternative and supplement to the typical MINI front - wheel drive.
If both the all - wheel drive clutch and the decoupler are open, the large components in the rear -
axle differential relevant for friction and drag losses as well as the propshaft stop.
When the driving stability system is deactivated (DSC Off mode), there is an electronic locking function for the front
axle differential known as the Electronic Differential Lock Control (EDLC) which selectively and appropriately brakes a spinning drive wheel on tight corners, redirecting the drive torque to the other wheel.
The 2.0 - litre four - cylinder turbo will be paired with a seven - speed dual - clutch gearbox and come with a front
axle differential lock that VW promises will improve traction.
Fun up and NVH (noise, vibration, harshness) down with the rear
axle differential with a new reinforced mount.
An integrated decoupler in the rear -
axle differential also opens, shutting down the primary cause of drag losses in the rear section of the drivetrain.
Rear - axle steering and Porsche Torque Vectoring Plus with fully variable
rear axle differential lock increase agility and dynamics, and the wider front and rear track widths enable even better roll stability than in the 911 GT3.
Drive is sent through either a six - speed manual or a Steptronic automatic transmission to the front
axle differential.
According to Audi, that entails» an electronically controlled multi-plate clutch along with a decoupling rear
axle differential to achieve fully variable torque distribution.»
It comprises an AMG Performance suspension with stiffer tuning, an AMG rear
axle differential lock, composite brake discs at the front and a three - spoke AMG Performance steering wheel finished in nappa leather with Alcantara ® inserts in the grip areas.
Thanks to the rear -
axle differential lock, the PTV Plus system makes a positive impact by reducing rear wheel spin through targeted locking and braking interventions.
The sportiest C - Class ever features the new 4.0 litre V8 biturbo with 476 HP or 510 HP developed entirely in Affalterbach as were the Ride Control suspension, the Dynamic Select drive programmes, the rear
axle differential lock and the dynamic engine mounts.

an axle differential.
Ceramic composite brakes are standard, and the car gets a sports suspension and mechanical locking rear
axle differential.
The technical highlights include the sports suspension based on Active Body Control, the rear -
axle differential lock that now features as standard, the even more responsive AMG Speedshift MCT 7 - speed sports transmission and the five AMG Dynamic Select driving programs.
An optimised rear -
axle differential and Dynamic Torque Vectoring system also enhance the overall direction change of the car — and should help to put some of the Chiron's prodigious amounts of twist onto the tarmac.
Unlike some systems that use braking on an inside wheel to help a car trim its line mid-corner, GM's uses two electronically controlled multi-plate clutches in place of a traditional rear
axle differential.
Further down the mechanical gimmicks list we encounter electronically controlled dampers, an active rear
axle differential lock and an all - wheel - drive setup (most likely very similar to that of the current BMW F90 M5) that favors the rear axle.
All versions have low - range gearing; a locking rear
axle differential is optional.
Standout features include a Pit Speed limiter, rear axle steering, Porsche Torque Vectoring Plus, and a fully variable rear
axle differential lock.
