Sentences with phrase «extra acceleration power»

Not exact matches

A 6 kW electric motor in the main wheel provides extra power during acceleration and taxiing to reduce electrical power consumption on the ground.

LaFerrari takes advantage of the electric boost in a straight line, where the tires can handle the extra power output, but when the car is exiting a corner and the tires, limited by grip and lateral acceleration, can only transmit a limited amount of torque to the ground, the KERS system uses the V - 12's excess torque to recharge the battery pack.

The engine can practically stay in high gear all the time when the e-motor can step in and provide extra torque when needed, except in «GTE» power mode when gear shift is necessary to wring out maximum acceleration.

The V8's acceleration and top speed numbers are beyond impressive, but the V8 doesn't have quite the private - jet feel its W12 - powered stablemates have — the 12 just has that little extra... something.

The gasoline engine will serve as the main power source, and the electric motor will assist when extra power is needed, such as during passing, start up and acceleration.

We felt the engine was noisy when starting up for extra power (as if motor was falling out of vehicle) and poor acceleration from 0 - 60 even for a hybrid.

When I slammed the accelerator for some quick acceleration, the CVT readily changed ratios, pulling extra power from the engine.

During normal driving conditions, these extra valves will be closed, but they'll open during harder acceleration, creating lower backpressure, more engine power, and that beautiful Corvette signature sound.
