What does Vauxhall Astra's 'ECO mode' do?

I recently purchased a Vauxhall Astra and noticed a button with 'ECO' labeled on it. What does this mode do and how will it affect my driving experience?

The 'ECO mode' in Vauxhall Astra reduces the engine power and optimizes fuel consumption. It changes the engine response and shifts earlier, resulting in a smoother acceleration. It also adjusts the heating and air conditioning system for better efficiency.

In my opinion, using the 'ECO mode' can save you money on fuel and reduce your carbon footprint. However, it may affect the performance of your car. If you prefer a sportier driving experience, you may want to keep the mode turned off.

I have been using the 'ECO mode' in my Vauxhall Astra and have noticed a slight decrease in power. However, I've also noticed an improvement in fuel efficiency and emissions. It's definitely worth using for daily commutes or long trips.
