Struggling to drive fiat 500

My instructor had a fiesta then a vauxhall and I stalled barely ever. However, im three days into having my Fiat 500 Lounge and I am stalling constantly and find it hard to drive off again once I have. Please can people give tips and advice. Thank you

I know exactly what the problem is. Your instructor probably had an Ecoboost or diesel engine in the fiesta and a diesel vauxhall. Both of these cars have highier torque (rotary force) than your fiat since it's a petrol with no special injection. Diesels produce more torque than petrol making them harder to stall at the cost of running out of puff at highier speed faster. Some petrol cars (like the Up or Fiesta) have specialist fuel injection (Ford Ecoboost or VW MPi) which allows them to have diesel like torque and move away just on releasing the clutch alone. Your fiat doesn't have any of these things, and you not being used to the lower torque is what is causing the car to stall.
It sounds like your instructor gave you a bad habit of not increasing power sufficiently before moving off. Do this, rev the car to maybe 1500 - 2000 rpm and slowly release the clutch to start moving. Do the same for all petrols and even diesels, regardless of they are turbo/spec injection.

Would 2nd this - the Fiat I drive has a really high biting point, so get the revs up first, then slowly release the clutch to the biting point and you should feel and hear the difference. It definitely does take some practise though so don’t worry!
