As a fellow amateur I am guessing it might just be how the transmission is tuned for highway vs. off-road driving in the 2 vehicles.

More than the tuning, its the FWD nature of the S-Cross which helps in reducing the strain on engine.

Front wheels are kind of directly connected with the engine in a FWD with the help of dedicated drive shafts transferring power to each wheel. This results into much lesser power loss compared to the similar specced vehicle with the RWD setup which has a single long driveshaft transferring the power into an axle, then transfer the power into the rear wheels.

FWDs are also much easier to handle, drive and control during the daily day driving conditions for a normal joy, especially in case of mild under or over steers. But if an inexperienced, non-enthusiast routine office-goer person ends up with under or over steer during incremental acceleration in a RWD car then chances of turning it into a disaster are much higher.

FWDs are also more fuel efficient and cheaper to manufacture. Thats why the majority of commuter category cars are sold with this setup.

Its not always about the engine or transmission, but how the actual car shape is. S-Cross is far more aerodynamic than Jimny, which has the aerodynamics of a brick. So it takes far more effort to reach the same speed in the Jimny than in S-Cross.

I am not sure that we can take whatever is said in this video at face value.

The 235/75/R15 has 6% larger circumference than the stock tyres - and thus 6% speedo error. This means, that when they measured the 0-100 kmph timing for the Jimny with 235s, they were actually measuring the 0-106 kmph timing.

In reality, the time difference may be much smaller - perhaps even lesser than 1 second.

Also, note that the Jimny with 235/75/R15 will reach 100 kmph at a slightly more relaxed engine rpm of around 2750 rpm (compared to 2900 rpm for the stock tyres) - thanks to the larger circumference of 235/75/R15 tyres.

Any updates on fuel economy for Jimny? 2-3 posts mentioned speedometer showing FE as 7-8 kmpl but considering them as a test cars they must have been used on lower gears a lot.

Anyone got actual on road mielage yet? Also enquiring about OTR price in Pune but still SE had no clues it seems. Anyone got any clue about OTR price in Pune?

Besides, its better to have the proven mechanicals globally of the K15B and 4AT.

Overall engine note felt much better in K15B, due to which I would not mind even if it has slightly higher growl inside the cabin.

So overall in contrast to my initial display on the GB choice by Maruti, obviously from the options within their stable, I would prefer the 4AT on Jimny over the 6AT.

These 2 posts amongst others greatly point ot the fact that new is not always better. Very nice analysis.

The old Jatco 4AT you are talking about here is Model 405E used in Astar, SX4 etc right?

Also can any of the Jimny owners share the ATF maintenance schedule (ATF spec and change interval)?

As per the 2023 Jimny owner's manual, the ATF needs to be changed every 165,000 kms or 11 years whichever is earlier.

It is the information or lack thereof regarding the change interval for the manual transmission that is concerning.

As per the manual, the transmission fluid in the manual variant does not need to be changed till 80,000 kms or 8 years (the manual does not go beyond 80,000 kms/96 months). This almost seems like an error as I have never seen such a thing in 27 years of owning 11 different vehicles 4 out of which came with manual transmission. 80,000 kms change interval for the manual transmission fluid is definitely pushing it, especially in Indian conditions (more dust/particulates).

My suggestion: change the manual transmission fluid at 50,000kms (I have spent 22 years in the automotive/industrial lubricants industry & yes, I know what I'm talking about). Transmission fluid is cheap compared to the cost of a brand-new transmission besides the quantity required is a meager 1.2 ltrs.

I'm enclosing the maintenance pages in addition to the fluid specs page & bulb replacement guide for everyone's reference.

Get in touch with Shibu Varghese a.k.a Jeep Captain. He's here on teambhp as well. He can guide you.

Dr. Tejas Kothari runs a 4wd school in Mumbai.

In Chennai there's Madras Battle Axles and Terra Tigers. As well as other groups.

Most of what is pushed around as new technology is merely inferior technology - forced by rapidly escalating fuel efficiency standards that the govts are forcing down the throats of automakers.

Among such new technologies - the cake goes to turbo-petrol engines - small sized engines generating large power output - primarily aimed at meeting fuel efficiency norms.

They have such weak low-end pulling that it's a pain to drive them inside cities or in the hills, where it's difficult to maintain the engine above 2500 rpm. Frankly, i feel sorry for the crowd which buy cars like Kushaq with the 1.0 litre turbo petrol engine. What a pain it's to drive anywhere, except on open highways.

The reliability and durability of these turbo engines are very questionable.

K15C is another new technology which mainly achieves better fuel efficiency, while being inferior at everything else.

Hope this Helps !
Dealer still says its tentative pricing though.

Power train wise Maruti is now archaic, purely commuter spec. Let's not think of the old Ecoboost and imagine 1.0 TSi to be like that, it will blow NA engines straight out of the water when it comes to performance, there is no getting away from it, be it the 1.6 VVT or the 1.5 ivtec in Verna and City respectively.

Turbo charged engines are good at high altitude, the only trouble is if the gearing is not proper , however they are still better than small NA engines because, Turbo charging is invented to deal with altitude to begin with. The most inadequate powertrain for hill driving in my experience is the K15C with 6AT, the only reason Jimny does not have it is because MS did not have enough time to shoehorn it into the Jimny, I think Sirish Chandran happened to mention it.

We have the Ciaz 4AT with the older K14B engine, and it does have the Aisin box.

Agree with this at engine rpm higher than 2500.

Problem is - 90% of Indian drivers, drive 80% or more of the time at below 2500 rpm. Our cities and roads are like that only.

I can’t say I agree with this view. Modern turbo-petrols are now a popular tech for manufacturers to help comply with stringent government norms - yes.

They aren’t exactly new tech - yes. But that’s where your your accuracy ends I’m afraid.

Small capacity turbo petrols are a boon for their volumetric efficiency. Lower volume combustibles intake = lower volume exhaust gases = less pollutants in the air, thus complying with stringent norms that are now a mandate. That isn’t such a bad thing if you think about it, considering you mostly get better fuel efficiency as a byproduct of higher compressions in the combustion chamber.
A lighter engine block and steeper power curve also means you get your Yeehaa! moments much earlier in the rev counter than a typical NA engine. So that’s one for the thrill.

But, are they the be-all of modern cars? Nope. Their applications are best left to road-going passenger (read family) vehicles and not case specific off-readers like the Jimny and other petrol models, where sudden power surges won’t be as welcome as a steady flow from the K15B unit. NA engines are also much less complicated with fewer components than a turbo or a bolt-on turbo that one can now buy for Jimny’s. Naturally, they are more durable and helps the car gain it’s bulletproof reputation. All for it myself.
