Performance & Engine of Rolls Royce Spectre in Bangladesh

The Spectre moves away from internal combustion entirely, utilizing two Separately Excited Synchronous Motors (SSMs). Unlike permanent magnet motors, these do not rely on rare earth materials and allow for finer control over the torque delivery. The front motor produces 190 kW, while the rear motor contributes 360 kW. This setup is engineered specifically to mimic the effortless, "limitless" surge of a V12 engine, but with the immediate response that only electric torque can provide.

With a combined output of 584 bhp, the Spectre is more powerful than the V12 Phantom. However, the power is delivered with extreme "politeness." The throttle mapping is intentionally softened during the initial pedal travel to prevent the neck-snapping jerk typical of many EVs, ensuring that the transition from standstill to high speed remains graceful for the occupants.

The Spectre matches the Phantom's peak torque of 900 Nm. The critical difference is the availability; while the V12 requires 1,700 rpm to hit peak torque, the Spectre provides it from 0 rpm. This allows the 2.9-tonne coupé to glide away from traffic lights with a ghostly silence and a level of ease that redefines the Rolls-Royce "waft."

The Spectre is powered by a 102 kWh battery pack. Beyond just providing energy, the battery serves a secondary structural purpose. It is integrated into the aluminum spaceframe floor, adding 30% more torsional rigidity compared to previous Rolls-Royce models. Additionally, the battery acts as nearly 700 kg of sound deadening, effectively insulating the cabin from road noise coming from beneath the vehicle.

Despite weighing significantly more than the Wraith it effectively replaces, the Spectre hits 100 km/h in 4.5 seconds. This performance is intended for "spirited" grand touring. The acceleration is accompanied by a bespoke "Rolls-Royce Soundscape," a subtle, synthesized low-frequency hum that provides the driver with a sense of speed without breaking the silence of the cabin.

The Spectre offers a range of approximately 530 km, which Rolls-Royce research suggests is more than sufficient for their clients, who average 5,100 km of driving per year. The vehicle supports 195 kW DC fast charging, allowing the battery to go from 10% to 80% in about 34 minutes, providing 100 km of range in just 9 minutes of charging.
