Audi's new sport differential, debuted 'torque vectoring' to quattro generation V. The Audi sport differential allowed the dynamic allocation of torque across the rear axle of the debut vehicle: the B7 (2008) S4, and is now an optional addition to all quattro vehicles, which continue to use the 40:60 asymmetric Torsen (Type "C") centre ...
Torsen differential from an Audi quattro. Torsen Torque-Sensing (full name Torsen traction) is a type of limited-slip differential used in automobiles. It was invented by American Vernon Gleasman [1] and manufactured by the Gleason Corporation. Torsen is a portmanteau of Torque-Sensing.
Audi Quattro Torsen Differential. Geared, torque-sensitive mechanical limited-slip differentials use worm gears and spur gears to distribute and differentiate input power between two drive wheels or front and back axles. This is a completely separate design from the most common beveled spider gear designs seen in most automotive applications.
On the mechanical side, the S4 25quattro was the second Audi, after the B7 RS4 to be fitted with the latest Torsen T-3 asymmetric ATB centre differential for its quattro permanent four-wheel drive system. Under normal grip conditions, this is set with a default rearwards torque distribution bias of 40:60 front to rear, and a maximum of 100% ...
Available in Coupé and Cabriolet bodies, it is a version of A5 with 4.2 FSI engine rated at 450 PS (331 kW; 444 hp) and 500 N⋅m (369 ft⋅lbf), seven-speed S-Tronic transmission, quattro permanent all-wheel drive system with crown-gear centre differential and torque vectoring (optional quattro with sport differential rear axle), 20 mm (0.79 ...
When one wheel begins to slip, the differential can reduce the torque to that wheel, effectively braking the wheel. The differential also increases torque to the opposite wheel, helping balance the power output and keep the vehicle stable. A rear-wheel drive torque vectoring differential works similarly to a front-wheel drive differential.
Audi looks poised to join in on the extreme off-road segment with its latest EV SUV concept. Known as the Audi Q6 E-Tron Off-Road, this portal axle-rocking beast takes things far beyond the brand ...
Output is transmitted via Audi's quattro generation IV all-wheel drive system, initially using the Torsen T-1 50:50 dynamic centre differential, and from 2007 for the 2008 model year, utilising the Torsen T-3 asymmetric dynamic centre differential, with a "default" torque distribution of 40 percent to the front axle and 60 percent to the rear ...
