What's that technology called that Mazda has It stores electricity from the forward momentum and uses it to move the car forward?

I'm not sure if it's a Mazda or Toyota, but it stores some of the energy from the forward momentum into a battery and then uses it to move the car form a standstill point instead of using petrol

I'm asking because I'm trying to recommend a car that has this technology after his Ford Telstar vehicle had died.

Added (1). Update: I think it's also in Toyota Camry's from 2015 to 2018 because I always hear this slight whistle from these Camrys as they decelerate. I assume that is the generator storing the electricity so that it can move the car from a standstill point instead of using petrol.

This is a feature of all all electric cars. It's called regenerative braking.

You are thinking of the Toyota Prius with its hybrid drive system. The car has a battery and electric motor system that can drive the car under electric power only (at slow speeds), and slow the car down by converting forward motion into electricity, then storing the electric energy in the battery. Most of the time the Prius will run the gasoline engine in the most efficient way possible, under computer control, to drive the car forward and charge the battery for the next time the electric motor will be needed to assist the engine or power the car silently with the engine off.

Are you asking about hybrids?
