deceleration peaks in the range of 1.2 g; lateral acceleration peaks of over 1.1 g and optimum weight distribution 40 % over the front axle and 60 % over the rear, not to mention a power - to - weight ratio of over 250hp per tonne, values worthy of true supercar.
While the car is
on the move, the electric drive itself contributes to a favourable energy balance through recuperation, by converting kinetic energy into electric current in
deceleration mode and during
braking and feeding this energy into the battery.
A gyro measures the rate of
deceleration and flicks
on the LED
brake lights accordingly.
Also standard
on New Generation i20 is Hyundai's Emergency Stop Signal (ESS) system, which activates the hazard warning lights if a driver suddenly
brakes heavily, warning drivers of following vehicles of the car's rapid
deceleration.

deceleration front, the E 63 S can be had with carbon - ceramic
brakes that will set you back nearly $ 9,000.
2006: the «Pre-Safe Brake»
on the CL - Class C216 [44] was their first to offer partial autonomous
braking (40 %, or up to 0.4 g
deceleration) if the driver does not react to the BAS Plus warnings and the system detects a severe danger of an accident.
Using sensors that monitor throttle position, vehicle speed, and acceleration /
deceleration and then comparing these inputs with a map stored in the transmission computer, the system is able to determine when the vehicle is
on an incline and adjust the shift schedule for improved climbing power or downhill engine
braking.
This is demonstrated by a top speed in excess of 250 km / h, only 4.5 seconds to accelerate from 0 to 100 km / h, 1.1 of side acceleration
on corners and 1.25 g of maximum
braking deceleration.
Just by closing the valves
on deceleration Honda was able to improve regen
braking efficiencies by about 10 %
on their new civic, I believe.
The regenerative
braking system efficiently converts kinetic energy to electricity during
deceleration, stores it in capacitors and then uses it to power the vehicle's electric equipment, thereby reducing load
on the engine and saving fuel.
Still, there are enhancements for the 2015 model year, including a standard backup camera and leather - wrapped steering wheel, a new «Brake» drive mode
on the gearshift that increases regenerative
braking during
deceleration, a light in the charging port and the ability to unlock its little door from the key fob, as well as an available energy - saving hybrid heater system.
The system uses an integrated starter and alternator to reap and harvest power depending
on need and opportunity and can recover power under
braking and
deceleration.
The
deceleration is dependent
on the driving condition and is split into a recuperative
brake - force portion and a portion to be supplied by the wheel
brakes.
Thus, the new M5 will be equipped with engine start - stop capability,
brake energy regeneration (this is when the alternator works overtime to charge the battery
on deceleration to minimize alternator drag when the car is in cruise and acceleration modes), and a variable flow oil pump.
While the car is
on the move, the system converts kinetic energy into electric current in
deceleration mode and during
braking, feeding this energy into the lithium - ion battery, which is located underfloor.
