Micro Hybrid

Although not strictly a hybrid (electricity from the battery is not used to propel the car), what is more commonly known as 'Stop-Start' does enable a modest reduction in CO2 emissions and fuel consumption. When the car comes to a halt, the petrol/diesel engine is shut down (at traffic lights, for example) and re-starts only when the driver activates the accelerator. The engine is instantly re-started by the alternator, which is powered by the car's battery which, in turn, receives a small boost charge from energy recouped during braking.
