What is the top speed of Tata Nano?
Let’s think first. It has only 33 hp, so probably it won’t be able to climb mountain roads without everyone getting out and pushing it uphill. A 33 bhp engine would be strained and quickly slow down on an uphill grade. Going uphill too long without stopping the strain, would probably burn the motor up. From India Times: The engine performance is a 623.6cc engine making 33bhp at 5000rpm coupled to a lusty 48 Nm of torque at 2500rpm. In fact the commuter nature of the car is best shown on the torque front with the low engine speed peak torque is produced, staying in a linear line all the way to the upper ends of the rev range.
