Drive

Platform information and proposed QAF engineering. Component imagery is illustrative; final configuration and regional performance require validation.

A smooth first metre. An unhurried arrival. The proposed calibration begins there.

Two layouts

The three-door carries a permanent-magnet synchronous motor on the rear axle: 50 kW, 140 Nm, driving the rear wheels through a single-speed reduction gear. The five-door carries its motor on the front axle: 75 kW, 180 Nm. Both are being considered for frequent, short guest journeys. A QAF spends its life between walking pace and forty kilometres an hour, and the useful numbers are torque from rest and the smoothness of the first metre.

The QAF calibration

We do not change the motor or the inverter. We change the map: a softer first ten per cent of pedal travel, so a guest is not moved before they are settled; creep at walking speed for a forecourt; a speed limit set in software per fleet, per zone, from the telematics; and regenerative braking tuned to one pedal in the district and coasting on the road.

Quiet

Electric drive removes combustion noise; motor, inverter, tyre and road noise still need attention. The Emerald's laminated glass and the extra insulation under the floor are there for those two sounds.

Vehicle-to-load

Vehicle-to-load is a proposed hosting option based on platform capability. Output, compatible appliances and available operating time must be confirmed for the chosen vehicle and regional conversion.
