Yup our very own Indian Accord V6 uses this tech. Quite good mileage for a 6 cylinder auto with 220bhp on tap.

No it doesn't. The Indian Accord didn't get Variable Cylinder Management. It's found on the Japanese version of this Accord, called the Honda Inspire.

I read this in ACI about the cylinder management in the Indian Accord, need to check it up and get back, its there in the Indian Accord IMO.

Adding further, the new technology in terms of hybrid vehicles are also effective. A petrol -electric or desil -electric hybrid will consume lesser fuel, provide more startup torque (due to electric motor), and provide a punchy city ride, without compromising on fuel economy. The best examples of desil-electric usage can be seen on our locomotives, tremondous torque, power and a decent milage of close to 2 kms per litre pulling a 24 coach train.

as far as a stock petrol engine is concerned , nothing can be as fuel efficient and power generating than a bi-vanos and valvetronic put together , which will only be found in a BMW...
cheers

Question 'underpowered' - is it purely subjective?

Hi

Is there any objective way to decide that a car is underpowered?
For example, would total weight, engine BHP/Torque, ambient temperature (for AC requirement) come into an equation to determine that a car is underpowered?

If it were so, one could add it all up, to choose a vehicle of certain trim having engine A versus a different trim with engine B.

This would be much easier than hypothetically taking 5 persons and luggage for a TD

Or is it purely subjective - based on how one wishes to drive, and whether the vehicle can overtake etc.?

Thanks in advance.

Regards,
Sridhar

Good question. If one wants a simple answer, yes in the end it all boils down to subjective opinion whether a car is underpowered or adequate. It all depends on the vehicle the person is using as an industry or personal standard (or point of reference) when comparing another vehicle. This is the case in point when it comes to it, one tends to refer to the segment leader of power to weight ratio when comparing with another car to determine if its underpowered, even though the power/torque of the said vehicle may be more than adequate to match average country speeds.

Underpowered is confusing because what exactly is one referring to when he/she means that? Is it 0-100 timings? Or is it torque to move about smoothly in traffic, or is it weight carrying capacity at speed? Sometimes overpowered vehicles would be inconvenient in traffic as they may have too much torque to smoothly inch forward. Each vehicle has a different power-band setup afterall.

Technically the best way to somewhat gauge the power of the vehicle is to calculate its hp+torque to weight ratio, even though there are variables like drag co-efficient (wind speed), gearing ratios and tire specs. It can thus be concluded that power is subjective based on needs/usage of each person, because of which there would be no single car that would be perfect across all needs.

Default Re: Do we really NEED more horsepower?

Thanks.
So as I understand, there is no easy rule-of-thumb formula that includes engine specs and total weight of passengers. To be sure the car is sufficiently powered, the buyer has to do a TD with all on board.
