Recently done a trip from Mumbai to Pune in my Linea MJD.. My observation is, Linea MJD, with and without AC, are simply two different cars.. The response when AC off is totally different.. The car has excellent pick up, even in lower gears, accelerates much faster, feels very smooth and agile, even with full load... However, the moment the AC is switched on, the response in lower gears (1, 2 and 3) immediately becomes sluggish... Feels like driving a tractor..
