I’m still at 48.0mpg after 1 month, 2 tanks of petrol and ~800 miles of ownership.
Since getting this car, I would say I have driven 98% ‘sensibly’ and pretty much always drive smoothly, including acceleration, cruising and deceleration using the hybrid technique. I stick to 60mph on the motorway; occasionally 65mph.
90% of my mileage is motorway.
Just found data from a 2500 mile drive I did to Europe last summer (hottest week of the decade; dash display frequently showed the temp to be 40 degrees Celsius!) in a small 2 door 1.6 petrol car, and giving absolutely no mind to economy; accelerating as I wanted and overtaking etc, and I got 45.5mpg; that was all motorway and never less than 70mph; much much faster in Germany where I think I did 80-85mph for hour after hour. A/C was on full blast ice cold the entire way, and due the heat continually overpowering it, I had to have the window party open; so all really bad for economy.
I can only explain the relatively poor economy of my 2.0L Corolla TS by the fact that it’s winter and every drive I do now, I have the heater on (and often A/C as the car keeps steaming up).
I didn’t choose the Corolla TS Hybrid for economy, but now I have it, I have become quite fixated on it!
I hope to do the same European road trip hopefully this year Summer or next year, and will be very interested to see what mpg I get.
