I have a Škoda Superb L&K 2022, which comes with a front-wheel-drive (FWD) drivetrain, while in some international markets, the Superb has been offered with a rear-wheel-drive (RWD) setup. My first question is: how does FWD differ from RWD in terms of basic driving dynamics? Secondly, what does chassis weight distribution mean in a car, and what significance does it have for driving dynamics and handling? Is an ideal weight distribution necessarily associated with an RWD setup? Also, is it correct to say that RWD is always better than FWD or AWD? Finally, does a four-cylinder engine with twin turbochargers have any significant advantage over an inline-six-cylinder engine?

The Skoda Superb is a front-wheel-drive car globally, including in international markets. There is no rear-wheel-drive version of the Superb. The confusion may come from the fact that some premium sedans in the same segment, such as the BMW 5 Series and Mercedes E-Class, are rear-wheel drive, but the Superb itself is not. The Superb is available in some markets with AWD (all-wheel drive), but that too is a front-biased system with the rear wheels driven only when needed.

The difference between FWD and RWD is most noticeable in driving dynamics. In a front-wheel-drive car, the front wheels are responsible for both steering and putting power down, which can lead to understeer (the car does not turn as much as intended) and torque steer (the car pulls to one side on its own) when pushed hard. In a rear-wheel-drive car, the front wheels steer while the rear wheels deliver the power, which generally results in better balance and a more engaging driving experience, especially in performance driving.

Weight distribution refers to how the car's mass is spread between the front and rear axles. A 50:50 weight distribution is often considered ideal because it helps the car remain balanced during cornering. This is not exclusive to rear-wheel-drive cars, but it is easier to achieve in RWD layouts because the drivetrain components are more evenly distributed along the length of the car.

It is not correct to say that RWD is always better than FWD or AWD. Each layout has its own advantages. FWD is more space-efficient, cost-effective, and better in slippery conditions; RWD offers better driving dynamics; and AWD provides the best traction in all conditions.

On the engine front, a 4-cylinder twin-turbo can produce impressive power and torque, and tends to be lighter, but an in-line 6 or V6 is inherently smoother and more refined. A larger-capacity engine tends to also be more effortless than a boosted low-capacity engine making the same power output. The choice between the two depends on the application: the 4-cylinder is lighter and more efficient, while the inline-6 offers a more premium and refined driving experience.

I’m looking for an Audi, BMW or Mercedes-Benz test-drive car that has covered less than 5,000 km and is priced within a budget of Rs 65-70 lakh. Which would be the best cars available in this budget?

Firstly, don’t assume that a low-mileage test-drive or dealer demo car will be easy to find. The best examples are often sold quickly, and availability will vary sharply by city, dealer and model.A Mercedes-Benz E-Class would be our pick if you can find a clean, well-specced example, but even one with under 5,000km may stretch beyond your Rs 65-70 lakh budget. Also, many dealer demo cars are unregistered. That means you become the first registered owner, which is a plus, but it also means the dealer may not discount it as aggressively as a formally pre-owned car.You could also look for a BMW 5 Series LWB demo car, although finding one within budget may again be difficult. The more realistic option could be an Audi A6, especially because Audi has historically offered strong discounts on outgoing or slow-moving stock. Do check availability with your local dealer, though, as stock can be limited depending on the city and the model year.For this money, our more practical recommendation would be a nearly new BMW 3 Series. It is likely to fit the budget more comfortably, is genuinely engaging to drive, and should offer a newer car with lower financial risk than stretching for an E-Class or 5 Series.Whichever route you choose, insist on a full-service record, tyre and brake inspection, accident-repair history, remaining warranty details, and clarity on whether the car has been registered. A dealer demo can be good value, but only if the discount properly reflects its usage and age.
