Similar to the sport differential in conventional quattro vehicles, these motors allow torque vectoring — the targeted acceleration of individual wheels and thus an active distribution
of tractive power.
Driving dynamics The normal distribution
of the tractive power is clearly biased toward the rear axle.
Driving Dynamics The normal distribution
of the tractive power is clearly biased toward the rear axle in accordance with the weight distribution of the e-tron.
Gearshifting occurs practically without interruption
of tractive power within hundredths of a second, and so dynamically, smoothly and comfortably as to be hardly noticeable.
[4] The front and rear drive shafts are fully locked, forcing them to rotate at the same speed regardless
of tractive conditions.
There is the occasional hint
of tractive corruption to the steering, evident mostly as you tip into the accelerator with steering angle dialled in or on an uneven surface — and, to be fair, you don't feel it in four - wheel drive E-Paces.
In its basic setting, the torque - sensing centre differential delivers 40 percent
of the tractive force from the engine to the front axle and 60 percent to the rear axle.
This ensures that the high torque of 440 Newton metres in total — 240 Nm from the 1.4 TFSI plus an extra 200 Nm from the electric motor — is transformed into the required level
of tractive power when accelerating.
The high torque of 390 Nm in total (287.64 lb - ft)-- 240 Nm (177.01 lb - ft) from the 1.4 TFSI plus an extra 150 Nm (110.63 lb - ft) from the electric motor — is transformed into the required level
of tractive power when accelerating.
The overall gear ratio selected provides a balance between the amount
of tractive torque available from the electric motor and the vehicle speed range available before the EV mode is disengaged at higher vehicle speeds.
Not exact matches
Some
of the proposed requirements include: equipping new passenger cars that have powered side doors with an obstruction detection system and a bypass feature that allows a train engineer to manually override the door safety system; connecting new passenger cars that have either manual or powered exterior side doors to a door summary circuit that informs the controlling cab
of the status
of the doors to prohibit the train from developing
tractive power if any
of the exterior side doors are open; and safety briefings for train crews to identify crewmember responsibilities as they relate to the safe operation
of the exterior side doors.
Equal acceleration gives equal weight transfer, regardless
of where the
tractive force is being put to the road (weight transfer under acceleration is primarily a function
of wheelbase length, CG height, spring rates, and the amount
of acceleration).
The
tractive force
of a vehicle (exerted by tyres on road) is maximum when engine generates maximum torque, which makes acceleration directly dependent on engine torque.
The mass
of the vehicle is constant which makes acceleration directly proportional to force (here
tractive force exerted by tyres).
A drive wheel is a wheel
of a motor vehicle that transmits force, transforming torque into
tractive force from the tires to the road, causing the vehicle to move.
We had no occasion during our sunny week with this Outlander to test its
tractive abilities, but the elaborately - named Super All Wheel Control has three modes with increasing amounts
of dig: Normal, Snow and Lock.
Torque Vectoring Control, which automatically applies small amounts
of brake force to limit wheel spin at the front axle, further enhancing available
tractive force.
While this tuning reduces low - down torque, that is supplemented by the
tractive efforts
of a 32kW electric motor that can produce up to 170Nm.
Both actuation
of the clutches and gear shifting take place fully automatically and without any interruption in
tractive power.
When the vehicle requires additional
tractive power during rapid acceleration or while climbing gradients, the system can deliver an instant peak torque boost
of up to 3400 N · m (2,508 lb - ft) for a short period.
The Euro 6 turbo engine has a maximum torque
of 1150 N · m (848 lb - ft), providing the same
tractive force as a diesel engine
of this performance class.
Finally, to help the MDX itself get out
of slippery spots, a new generation
of Acura's Super Handling All - Wheel Drive debuts, doubling down on
tractive performance with a twin - clutch design.
The strengths
of the AMG DCT sports transmission include spontaneous gear shifting without any interruption in
tractive power, a tailor - made control strategy, extremely smooth and easy gear shifting and a high level
of efficiency.
This also increases the
tractive force: In Sport Plus mode, the time taken to accelerate from 80 km / h to 120 km / h has dropped to 2.9 seconds (a reduction
of 0.2 seconds).
