For the first time since I collected my GTI in March I tried 'Eco' mode. I never thought I'd use it but curiosity got the better of me whilst visiting a customer about 80 miles away this morning, and I was surprised, and very impressed by it.
The way the coasting function works is very impressive and I like the way it picks the gear back up to give you engine braking as soon as you hit the brake pedal.
So much so, on a 160-mile round trip I averaged 38mpg on a mix of Motorway/Stop Start and rush hour A-Road driving.
Excellent.
