At what Speed Bro!!!????
@ speed 130km/hr constant on Motorway Isd to Lhr (along with speeding up smoothly for over taking slower cars maintaining pace in order to avoid breaking due to car coming from behind above 130km/hr ) following driven cars gives:
Corolla 1.3 Xli or Gli = 13.1 km/L
City 1.3 = 14.5 km/L
Grande CVTi = 14.2 km/L
Civic Turbo 1.5 CVTi = 16.4 km/L
Hence i concluded Grande to be more economical than an Xli or Gli manual1.3.
Although this is a thread dedicated to corolla....I put the Hondas just for ref as i have checked thoroughly the above 4 only all in mint condition below 20k kms driven.
