I have a friend of mine who once I let him have a go in my Exora, his feedback was that the Exora is very powerful compared to his mom's Innova (he often drives his mom's Innova).
According to him, the Innova requires hard revving for it to accelerate decently. Whereas for the exora, once the turbo kicks in, all the acceleration power is there when you need it.
Since then, he constantly complains about his mom's Innova being underpowered and how he wishes he could turbocharge it

Moreover, on paper (the specs) the Innova IS underpowered.
Based on the calculations of the engine output figures (Horsepower, torque), and the kerb weight of the Innova.
The exora may not be the most powerful MPV around, but thanks to the 1.6 turbo engine, it's definitely one of the better performing MPVs.
The Innova doesn't have much torque despite being a 2.0 in order to lug around the massive weight of the car (due to the engine being naturally aspirated, as opposed to a turbo engine which has lots of torque)
Torque is very important to an MPV, just like how it is to a pickup truck

Myvi small and light ma. The engine doesn't need to work as hard to get it moving

i see, then probably you are right then. when i test drive exora and driving uphill, it felt powerful and no lagging (i dont need to over press the fuel pedal). but the engine noise is really loud (especially i compare to those peugeot turbo engine) but i guess it's a wrong comparison since the price nearly double what proton cost us right. so far are you happy with exora? any problems faced? How much you bought?
