Kia's Cee'd small family car will be available with a stop-start system from early next year.
Kia calls the system ISG Idle Stop Go and it works by cutting off the engine when the car comes to a halt and reignites when the clutch is depressed, which lowers carbon dioxide emissions and increase fuel efficiency.
The company plans to introduce ISG on all of its small cars, including the Soul, which goes on sale in March.
However, wait 12 months and you could get a Soul with a mild hybrid petrol-electric engine. A mild hybrid engine works solely in conjunction with the petrol engine, unlike true hybrids, which can run on their own at low speeds.
In the meantime, the Soul will initially be available with a 122bhp petrol engine or a 126bhp diesel unit, but a smaller petrol engine will be available later.
Kia also confirmed that a five-seat MPV, based on the Soul, will arrive in the UK late next year. The Citroen C3 Picasso/Vauxhall Meriva rival will be a standalone model and will not carry the Soul name.
