Why do reverse gear sounds in AGS?

Asked by: S Lanong
If by sound, you mean the whining or whirring sound you typically hear when reversing, then that is on account of the shape of the reverse gear wheel. In a manual gearbox, and thus automated manuals, forward gear wheels are helical-cut, which is to say the teeth mesh at a diagonal angle. This allows the engagement of teeth to be gradual and silent. A helical-cut gear can also handle more load. 
The reverse gear typically has straight-cut teeth; this is simpler and cheaper to produce, but causes the meshing of teeth to be more sudden, thus giving rise to the noise you often hear when driving in reverse.

Which family scooter or bike is best for both city and highway use for me? My height is 5′3″.

Coming to the 160cc class, bikes like the Bajaj Pulsar N160, TVS Apache RTR 160 4V, Honda Unicorn / SP160 and Yamaha FZ models are worth taking a look at.Take a test ride of all before you make a decision.

Hi AUTOCAR, I want to purchase the smallest car for solo driving. It should be safe, reliable, comfortable, and equipped with a good engine that performs well. My budget is 10 lakh, and my running will be around 1000 per month. Also, should I go with automatic or manual? Please advise.

Given that you travel extensively, choosing automatic will add to your day-to-day convenience. The Honda Amaze CVT meets most of your requirements well. It is a comfortable car with excellent ride quality, and the 1.2-litre petrol engine offers smooth and dependable performance. The VX petrol CVT variant should also fit within your budget.

Asked by: Manu

My monthly usage is under 1,000 km, with occasional long trips of around 500-600 km (round-trip) to temples. I am looking for a 7-seater. I have found a 4-year-old Hyundai Alcazar Prestige with a manual transmission, quoted at ₹13.5 lakh. The current seller is the second owner, and I would become the third owner. The vehicle has done approximately 40,000 km. Is this price justified? I plan to keep the car for another 10 years.

Hyundai is expected to discontinue the Alcazar soon. While manufacturers support spare parts availability for several years, availability typically reduces over time, and costs tend to rise. This can make long-term ownership and servicing more expensive and less convenient. Keeping this in mind, it may be worth considering alternatives that are likely to remain in production for longer.

I have been using a Skoda Superb car for the last few years. I am now planning to buy a new car. For some time now, I have developed knee pain. Considering this, would a SUV be better suited for me as compared to a sedan? Can you please also give me some recommendations for the car? My budget is up to ₹75 lakh.

While you are advised to personally test the vehicles to judge comfort, a higher-riding SUV usually is more comfortable to get into and out of than a sedan. There are a fair few options within your budget (do remember to haggle hard!), among which we'd suggest you check out the BMW iX1, BMW X3, Mercedes-Benz GLC, Audi Q5, Volvo XC60 and Land Rover Discovery Sport.You could also look at the Kia Carnival if you are open to the MPV body style.
