...You just cant plonk a tiny 1.3 L engine on a 1.25 Ton car can you ?
Thats why the car is so frustratingly slow ... You can make do with in a 1 ton car like a swift or a palio but not a linea, now thats stretching it .
For all the people who think the Linea is fast car, got test drive an SX4 or a City or even a Swift in that case which is a whole segment lower.
Avik, in general the observation is valid, but we are looking at two different things here, which have got confused and tangled.
By fast and slow, you mean the car acceleration is not good - this depends on the power to weight ratio, and probably you are justified with this argument above, where you say 1.3L and 1250kg do not match.
Now the response that I see above - taking a vehicle to 160 to 170 kmph, to call it fast, is also probably misleading. The final speed is one where the engine power is just sufficient to counter all resistance to the car's movement - it will be from aero drag, road and engine/transmission friction. As long as the engine power is sufficient to provide the power to propel the car at a given speed, the car will reach it, eventually. It is ot required that this speed be attained quickly - a fast car would achieve it quickly. So for most counts this theoretical top speed is meaningless, except that it too is dependent on the total power that the engine is able to muster at the higher end of RPM.
Keeping the engine slightly underpowered encourages use of the engine with nearly a full throttle, which is good for FE - ther vehicle suffers less pumping losses, improving FE. Hero Honda CD100 is efficient for the same reasons - puny 100 cc engine on a regular use bike.
Indians being overly fixated on FE, most Indian manufacturers focus on FE rather than performance, resulting in this situation. Not exactly bad, IMHO.
