Is it the 3 cylinder VXR? This car, like Khyber, Mehran, and Alto, has a surprising amount of low end torque. It makes excellent torque from 2300 rpm onwards (telling from years of experience).
As a general rule, these are the shift speeds: 1st - 2nd between 15-20 km/h, 2nd to 3rd 30-40 km/h, 4th 50-60 km/h, and 5th at any speed above 65 km/h. Cruise in the highest gear possible to go as slow as traffic, or else people will get in your way
If you want to overtake, your RPM should be at least 3k. If not, downshift. It will shoot like a rocket.
It has an automatic choke; engine RPM will be high during cold starting. This is normal; it will automatically settle down once the engine is warmed up a bit.
The brakes are OK at best. Never tailgate anyone. If you need to stop, plan ahead and brake earlier to avoid any mishaps. If in doubt, just assume that the car doesn't have brakes and drive accordingly.
I learned to drive on this car, I know all its strengths and flaws :D. Don't have experience with the EFi model, though.
