Diesel vs petrol cars: 2022 Jan to Sept model-wise sales figures

The availability of a proper automatic transmission (torque converter gearbox) has a significant impact on buying decisions for self-driven passenger vehicles.

BHPian pqr recently shared this with other enthusiasts.

2022 (Jan-Sep): Product-wise diesel-mix-trend

  • Diesel is the preferred choice for SUVs or MUVs having a body-on-ladder-frame chassis due to fuel efficiency and weight considerations, which are mainstays for Toyota and Mahindra.
  • Diesel becomes the preferred choice when petrol drivetrain’s value proposition is weak – Hyundai-KIA, Toyota & Jeep Compass.
  • The availability of a proper automatic transmission (torque converter gearbox) has a significant impact on buying decisions for self-driven passenger vehicles; unfavourable for the Hyundai Venue, Honda City, Mahindra XUV 300, Tata Nexon, and MG Hector.
  • Hyundai, KIA, Mahindra, and Toyota have a strong dependence on diesel powertrains for the UV portfolio.
  • The small diesel engine volumes of Tata and Honda are too low to sustain in the future (BS6-RDE phase).
  • Hatchback and sedan diesel drivetrain volume is too low to sustain in the future (BS6-RDE phase).

SUV: Ladder frame chassis

SUV/Crossover: Monocoque chassis




Here’s what GTO had to say about the matter:

These are the kind of stats that industry followers like us thrive on!

  • Diesel percentages of Nexon, i20, Altroz, WR-V & Venue show how diesel small cars are more or less finished. Goodbye, budget diesels. How Maruti predicted this trend is just remarkable.
  • Scorpio diesel mix of 96% is for the old car. The new Scorpio-N’s deliveries have only just started. I would expect it to be 25-35%. It’s a very good turbo-petrol that will appeal to urban dwellers.
  • Fortuner, no surprises there, Delhi-NCR 10-year ban notwithstanding. It still remains primarily a diesel car with just 3% of sales from the petrol. Of course, one reason will be that the old NA petrol itself is quite an average motor (unlike say, the modern turbo-petrols of other SUVs & crossovers).
  • What I find most interesting is how sales of the crossover champions = Creta & Seltos – are about half & half for petrol : diesel. Urban users, sure. But also, unlike big trucks (Fortuner), the petrol versions of these smaller SUVs still deliver acceptable FE. Plus, there is no large price difference between the turbo-petrol DCT & Diesel ATs.

Here’s what BHPian fhdowntheline had to say about the matter:

Hyundai Alcazar’s numbers look pretty interesting. For what is perceived as a “just adequate” performance of the 1.5 CRDI with 115BHP, it appears that people are comfortable with it over the petrol variant, which ideally should be the choice for that car.

This is also echoed somewhat in the Carens numbers with 53 % opting for diesel. Apparently, customers equate people-movers with diesel efficiency.

On the other hand, Hector’s 36 % for its arguably best powerplant option can only be explained by the lack of an AT transmission.

I also thought the Compass shows an interesting trend of 43 % owning the petrol version, which is way more than the popular perception.

Here’s what BHPian achyutaghosh had to say about the matter:

  • The monocoque petrol XUV700 is as potent as the diesel, yet 2 out of 3 XUVs are diesels. Petrol SUV value proposition will always remain weak because of efficiency concerns, so till the day diesel options are available, and there are no 10-year rulings applicable, most people will continue to buy the diesel options.
  • I am really surprised that petrol accounts for 2 out of every 3 MG Hectors sold. The petrol Hector is inadequate, by all accounts, and the resale market is flooded with them. Is the lack of automatic the only reason for the lack of diesel sales though, given the 2-liter engine is very good?
  • The Compass’ diesel skew may be also because of the availability of 4×4 in those variants.
  • The Scorpio didn’t get a petrol option till the launch of the Scorpio-N. So that 96% diesel number may reduce to a Thar-like 75% for Scorpio over time I guess.
  • The diesel skew in Alcazar is surprising. One may say heavier 7-seater, refined engine etc, but then the 7-seater Carens with the same engine doesn’t have that skew, as does the Seltos and Creta.
  • 5% petrols for Innova vs 3% of Fortuner. Didn’t realize the split is so close. I see a lot of petrol Innovas at least in NCR.
  • Would be good to have some break-ups for NCR if possible. These numbers will look a bit different.

Here’s what BHPian ashis89 had to say about the matter:

Diesels were popular when the fuel was cheaper and delivered better FE. While the slightly better FE of a diesel engine remains (BS6 spoils that too), the fuel price being at par with petrol has changed the reference/preference of the buyer. And the turbo petrols are smooth fun too.

Buyers have been avoiding diesels and moving to petrol due to DPF scare, NGT scare and of course, the perception of diesel having higher maintenance costs.

With increasing purchasing power, people don’t fret over the single-digit FE of a petrol. People who drive fewer thousand in a year, have realised they won’t save much going with the heavy dirty fuel. To compare, for someone driving 5-10k in a year, a petrol will have less than an extra EMI cost as additional fuel expense compared to a diesel.
