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.
I just got my driving license a few weeks before. I don't have much experience in driving cars. Now I am planning to buy one, as everyone says, small cars are good for new drivers I have shortlisted Tata Tiago XZ and Ford Figo Titanium MT. I didn't like Celerio. But I really like Baleno, it will almost drain my pocket, but is a big car like Baleno Zeta suitable for new drivers like me ? If it is better to stick with a small hatchback, which one is better ? Tiago vs Figo ?

There is one more suggestion that we would like to give you, as you are a beginner, you can also go for a used car and then practice then after you attain perfection, you can sell it out and purchase a new one.

You would need to check the owners manual for the driving instructions. Generally there are some instructions given by manufacturers to drive the car during the break-in period which is generally around 1000kms.
Yes, you can surely take a car for a long drive. You just need to ensure that you drive within the limits specified in your car.
A 2,500 km running-in period is ideal. After this, you can high-rev her away to glory.
For a petrol engine, don't allow the RPMs to go over 2,500 for the first 1,000 km. After that, you can increase the limit to 3,000 RPMs until 1,500 km and then, gradually increase it to the maximum by 2,500 km.
For a diesel engine, restrict the RPMs to about 2,200 for the first 1,000 km. After that, you can increase the limit to 2,500 - 2,800 RPMs until 1,500 km. Then, gradually increase it to the maximum by 2,500 km.
Long highway trips or time spent in bumper-to-bumper traffic is bad for the run-in process. The key to the run-in is to subject the engine to a wide range of RPMs, so you will probably have to alter your driving style and make a point of driving under various conditions.
