So the Euro version gets the lowest gearing for best fuel economy, even with smaller engines.
People interested in the fastest acceleration in all gears should combine the Canadian final drive with the gear ratios from the UK's 1.2L naturally aspirated Micra.
Even the lowest power 1.2L UK Micra revs lower in top gear than the Canadian Micra.
People interested in the best fuel economy should combine the Canadian (or UK supercharged) gears with the 3.438 f.d. from the 1.2L naturally aspirated Micra.
