A
mechanical differential is a device in a vehicle that helps the wheels turn at different speeds. It allows the wheels on the same axle to rotate at different rates, which helps during turns and prevents skidding.
Full definition
In fact, the steering and
mechanical differential work so effectively together that you can feel precisely how wide you can open the throttle before the front wheels will spin up.

different mechanical differential locks.
Further performance modifications contain
TRD mechanical differential instead of the stock Torsen unit, while the final drive ratio has been shortened to 4.8:1.

A trick suspension that includes something called dual access strut which reduces torque steer by up to 55 % a
funny mechanical differential electrically assisted steering and some pretty mental aero amongst other things of course.
The i30 N on the other hand does have something Hyundai also calls the Performance Pack, also bringing with it an electronically -
controlled mechanical differential (of Hyundai's own design, no less), plus bigger brakes and more power.
The Cup Racer is offered in two versions: one with a DSG transmission priced at $ 70,000 ($ 92,000) and the endurance version with a sequential transmission and
mechanical differential lock priced at $ 95,000 ($ 124,500).
SE Technology adds that to the mix, with 16 - inch alloy wheels replacing 15 - inch steel rims, front fog lamps with cornering function, a leather steering wheel and gear knob, chrome interior trim, cruise control and XDS differential lock, which essentually uses the brakes to try and mimic the effects of a traditional locking
mechanical differential.
When the twist action reaches the rear wheels, it is channeled through
a mechanical differential lock which works chip in hand with the electronic torque vectoring device.
Front - wheel drive becomes four, with the fitment of a Haldex all - wheel - drive system with Quaife front and rear
mechanical differentials to keep everything under control, combined with a set of six - piston calliper brakes from Brembo.
It wasn't so much the additional effort of the three - pedal dance, but
the mechanical differential out back that changed the game.
Due to the absence of transfer cases and
mechanical differential locks, in extreme conditions it's up to the traction control, ABS, and ESP systems to help achieve optimum stability when grip starts to slip.
«With
a mechanical differential, you're fixed on bias.
Unlike the current SH - AWD system, which would send power to the front wheels by way of a driveshaft and
a mechanical differential, the NSX's front wheels will instead be powered by a pair of electric motors.
Not fitted to our car, the PP adds 10 hp,
a mechanical differential lock, and larger vented rotors all around (the base car gets solid rear discs).
Also available is Porsche Torque Vectoring, which can dab an inside rear brake to improve turn - in, or lock up
its mechanical differential to boost traction on exit.
The Quattro hardware is similar to that in other Audi cars — a hydraulic clutch pack sends torque forward and aft and
a mechanical differential directs it to individual rear wheels — but the software has been improved such that it recalculates the proper torque split every hundredth of a second and can send up to 100 percent of its torque to the rear wheels.
It doesn't give the same slingshot acceleration away from a bend as
a mechanical differential and in slower second gear corners, with the traction control as off as it will go, it can struggle to get all of its power down.
It's agile too — running a short wheelbase and three
mechanical differentials for that trademark - Block - four - wheel - drift.
The 4MATIC system does not have
mechanical differential locks, but an electronic traction system (4ETS).
Rear - drive vehicles come standard with
a mechanical differential.
This includes Alfa Active Suspension (this is optional otherwise), self - locking rear
mechanical differential, paddle shifters machined from solid aluminium and 20 - inch alloys.
In most cars, the car's differential allows that to happen in proportion to how far each wheel needs to travel, but
mechanical differentials are stupid and think spinning one tire on ice or snow is actually the car taking a very tight corner.
The V6 gets 335 horsepower plus the suspension from the Camaro SS plus Goodyear Eagle F1 run - flat tires capable of maintaining grip to 0.97 g, Brembo brakes, an upgraded cooling system for the engine, transmission and
mechanical differential plus two outboard coolers.
Gears in
a mechanical differential make that happen.
A special variant of the Cup Racer for endurance racing can be equipped with a sequential racing transmission with a shift lever on the centre console and
a mechanical differential lock.
VAT), while the endurance version with a sequential transmission and
mechanical differential lock is priced at $ 95,000 (also excl.
For the 2013 season, the 1.4 - litre turbocharged engine now has 200 hp / 147 kW, a 7 - speed DSG operated from the steering wheel and
a mechanical differential lock for outstanding traction.
Those looking for the ultimate in road holding, or who regularly have to deal with poor weather conditions, can order Transporter with VW's 4Motion four - wheel drive system, including
a mechanical differential lock.
If one of the drive wheels threatens to spin, specific brake pressure is applied to create the effect of
a mechanical differential lock.
Driving safety optimised to an even higher standard is ensured by Dynamic Engine Mounts and Porsche Torque Vectoring (PTV) including

Thanks to
the mechanical differential lock on the rear axle, the driver experiences maximum traction without any slip.
There is the direct shift, dual clutch, 6 speed gearbox (DSG) transmission model, and the «Endurance», with a sequential trans and

If Volkswagen had beefed up

Drivers will smash these resources to the ground through a six - speed hydraulic - shift manual gearbox, a four - wheel drive setup, and two

Thanks to
the mechanical differential lock on the front axle (included in the Dynamic Plus package for 2.618 Euros), the driver can jump on the throttle at a surprisingly early pace: the four - wheel drive sprawls forward, accompanied by the rumble of the 381 PS four - cylinder engine, which is particularly fierce in the low engine speed range.
In order to put this force safely to the road,
a mechanical differential lock on the front axle was added.
