What is the use of Tachometer in car. How does it help for efficient driving
The tachometer is located on the dashboard next to the speedometer. It measures the revolutions per minutes (RPM). The tachometer can be a digital display or on a calibrated analogue dial. They are on both automatic and manual vehicles.
Purpose of the Tachometer
The tachometer shows the rotation of the engine's crankshaft. The purpose of this is to help the driver in choosing the right throttle, and gear for driving conditions. For vehicles that have analogue dials, the danger area is marked in red. If the tachometer is driven in the red for too long, this can cause overheating, inadequate lubrication, and excessive wear on the engine. This can shorten the lifespan of the vehicle or cause the engine to fail.
Tachometer shows the rate of rotation of the engine's crankshaft. They have markings indicating a safe range of rotation speeds.
They assist the driver in selecting the appropriate throttle and gear.
Revving the engine at high RPMs (rotations per minute) may lead to overheating, inadequate lubrication, high wear and tear (friction) in a short period of time due to consistent operation of engine parts at high stress and speeds.
Diesel engines have low revs, while Petrol ones have high revs.
So there is a lot of difference in running a Diesel engine @3000rpm and a Petrol one at the same rate.
Thus,the tachometer aids you in keeping your engine long lasting and gets you the best gas mileage provided you select the appropriate gear below the limiting RPM.
Revving the engine up to the red band may cause no serious harm provided it's in the red band for just a couple of seconds, else it may cause serious damage to parts like connecting rods, camshafts, valves, pistons etc. which may lead to engine failure.
But, if your engine is supplied fuel through a fuel injector, then continuous revving in the red band will cut off the fuel supply to the engine, thus preventing any serious damage.

The performance of Ford Figo 1.2 is pretty decent even on 3rd gear. Frankly saying, its better than its rivals.
Now, talking about the performance on hill, it totally depends upon the load that you are carrying into your car or the number of people sitting in the car. If the load is more than you need to switch the gear down in order to get the maximum output (Pick up) from the engine.
Rest, we recommend you to take a test drive of the vehicle to get a better clarity.
