Petrol Car or Diesel Car in 2021. Should you Buy Diesel Car in 2021

Petrol Car or Diesel Car in 2021. Should you Buy Diesel Car in 2021

Confused in Buying a Petrol Car or Diesel Car in 2021. Compare Upfront Purchase Price, Fuel Cost Savings with Maintenance Costs to know which Fuel Choice should you go for and Why

 

Petrol Car or Diesel Car in 2021 - Updated in Line with BS6 and Changed Scenario

Buying a car is an important decision - not only it reflects taste, style, aura and top of it the convenience - but it also is a big financial decision - thanks to high ownership cost of cars in India.

However, the Debate has taken a Paradigm Shift 

  • After BS6 Emission Norms been rolled where Emission levels are largely controlled in BS6
  • Price Gap in between Petrol and Diesel Models is largely Minimised (due to Economies of Scale as same Diesel Engine used in Multiple Models)

 

Pollution Levels in BS6 Diesel Cars and Petrol Cars

In BS3 and BS4 Regime Diesel Cars used to emit more than 3 times Nitrogen dioxide pollution and 22 times more tiny particles which penetrate the lungs, brain and heart.

But see how Scenario changed from BS6 where by using

  • Diesel Particulate Filter
  • NOX Reduction in Diesel Cars by using either NOX Trap or Adblue and BS6 Diesel Cars  

and by Upgrading Catalyst are what Diesel Cars Pollutants been reduced Significantly. NOX Levels which were almost 300% in BS4 in Diesel against Petrol, now just is 33% higher than Petrol in BS6 Regime

Infact from BS3 to BS6 - NOX Levels in Diesel Cars dropped by 1/6th and PM Levels by 1/10th.

 

 

 

Diesel Cars Performance

Lot of Diesel Cars are what Discontinued. Now no more Diesel Cars in market which used to be available with Turbo Lag. Present Range of Diesel Cars

  • Ford 1.5 TDCI Diesel Engine is explosive and offers lag free Performance
  • Hyundai 1.5 Diesel Engine ofr Immaculate NVH and Performance in Venue, Creta, Seltos
  • Tata 1.5 Diesel Engine in Different State of Power used in Altroz and Nexon 
  • Mahindra XUV300 Diesel Engine which is a Gem of 300 NM Torquey response

Care for a Power Driven Performance Car, you Drive and experience it. It will bring a smile on your Face. We bet

Ford 1.5 TDCI Diesel 4 Cylinder Engine as used in Figo, Aspire, Freestyle, Ecosport just takes the experience to next level if compared against 1.2 Litre 3 cylinder or 1.5 Litre 3 cylinder Engine as what used in these Cars

Tata Altroz Petrol or Nexon Turbo Petrol - you will find a substabtial Difference in Diesel Engine

Drive in 1.5 Naturally Aspirated Petrol Engine as what used in Hyundai Creta, Kia Seltos and then experience in 1.5 Diesel Engine. The kind of Diesel Engine NVH Level as attained in BS6 is what the Benchmark, clean Power Delivery will bring a smile on your Face.

Similarly, although XUV300 Turbo Petrol is very good, but XUV300 Diesel is just Awesome.

Diesel Cars Punch going to bring a smile on your face.

 

Price Difference in BS6

Some Diesel Models comes with Negligible Price Difference

  • Venue Sx Turbo Petrol and Sx Diesel is just Rs 20K On Road. Infact - Fuel Efficiency is a lot better of Diesel
  • Similarly - Ford Ecosport Diesel Price Difference is between Rs 20,000 to Rs 50,000
Model Prices
Hyundai Creta  

E Petrol

Rs. 9.99 Lakh

E Diesel Rs. 10.31 Lakh
   
Venue Select Variant  
Sx Petrol Rs. 9.85 Lakh
Sx Diesel Rs. 9.99 Lakh
   
Ford Ecosport  
Titanium Petrol Rs. 9.79 Lakh
Sports Petrol Rs. 10.99 Lakh
Titanium Diesel Rs. 9.99 Lakh
Sports Diesel Rs. 11.49 Lakh

 

Mileage

Although Fuel Price Gap in between Petrol and Diesel is narrowing

but The Fuel Efficiency of a Diesel Car is relatively 20% to 25% better as against Petrol Car. Expect Lower Running Cost of Diesel Car as against the Petrol one.

City Drive Conditions Ford Ecosport Petrol Ford Ecosport Diesel
Mileage Difference 11 Kmpl 14 Kmpl
Fuel Price in Jan 2021 Rs 85 / Litre Rs 76 / Litre
Average Running Cost Rs 7.72 / Km Rs 5.43 / Km

You can almsot save in Rs 2.3 Per Km as running cost as against Ecosport Petrol. So say if you drive in even 7500 Kms a Year you will end up saving in Rs 17,000 per Year in terms of Fuel Cost

 

 

Diesel Cars Ownership Cost Higher

1. Up Front Price Difference Cost

Although the Narrower Price Difference Petrol Cars in range of Rs 20K to Rs 50K specified in above pertains to Specific Model Variants as listed above, but if you choose in 

  • Tata Cars - Altroz and Nexon Diesel - Price Difference is very high at Rs 1.5 Lakh On Road Price Difference
  • If you choose higher up Variants of Creta and Seltos as Creta S Petrol to S Diesel, Sx Petrol to Sx Diesel. Seltos HTK Petrol to HTK Diesel - you will find On road Price Difference to to tune of Rs 1.25 Lakh+ Onwards
  • Ford Figo Diesel, Freestyle Diesel, Aspire Diesel also cost in Rs  1.25 Lakh On Road higher than counterpart 1.2 Petrol Engine

 

2. Higher Financing Cost

ยป If you buy Car on Finance - then there would be additional Interest cost for Buying Car in form of higher EMI or even if you buy car on cash - you would be forgiving the Interest which could have earned in form of Fixed Deposit at Bank

Finance : Interest on Rs 50,000 for 5 Years at 8% Interest Rate - Rs 10,840 and Rs 1.25 Lakh for 5 years at 8% Interest Rate (if Loan taken) - Rs 27,000 (Car Loan Interest is on Reducing Balance)

Own Funds : Fixed Deposit Interest on Rs 50,000 for 5 Years at 6.1% Interest Rate is 16,000 after TDS and 1.25 Lakh for 5 years at 6.1% Interest Rate - Rs 40000 (after TDS as Cumulative Interest)

 

3. Service Maintenance Cost

Additional is Service Maintenance Cost Difference where due to higher cost of Clutch Plate, Battery, additional cost of EGR Valve Cleaning, Oil and Fluid replacement Interval, Oil Filter cost. Some cars have bigger Diesel Engine requires more Oil

Even there are Parts like Catalytic Converter, Water Pump, AC Coils which though rarely fails - but if they do will cost higher in Diesel Cars vis a vis Petrol Cars.

On an average - its seen that Diesel Cars Maintenance cost if taken on Average Basis is higher to extent of Rs 2500 per Year against Petrol Model

You can check - Car Service Cost Comparison

 

4. Insurance Premium

Diesel Cars has higher Insurance Premium in later years with marginally higher risk cover as against Petrol Cars. Even - the internal loading discount in later years would be nullified in Diesel Cars as against Petrol Cars

  • On Cars with Ex-showroom Price Difference is Rs 50,000 - Expect Cumulative Insurance Premium to be higher by Rs 10,000 over span of 7 Years
  • On Cars where Ex-showroom Price Difference is Rs 1.25 Lakh to rs 1.5 Lakh - expect Insurance Premium to be higher to tune of Rs 20,000 over Span of 7 Years

  

5. Limited Life of Diesel Car in Delhi / NCR

Also a ban is imposed in Delhi, NCR for Plying 10 year Old Diesel Car (this was imposed in BS4 Regime and still continuing)

However, the way Diesel Cars Pollution Levels are well controlled in BS6 Regime - we do not expect the Ban to Extended to other Cities. 

But - consumers who are buying Diesel Cars in Delhi and NCR Zone can definitely sell these cars in other States by getting NOC Issued. (although to disclaim - fair price may not be reached but still can expect in 20% of Original Purchase price at end of 9th Year)


 

So Which to Buy - Petrol or Diesel

Pls understand Scenario Difference

Diesel Car Plus Points

  • Diesel Cars are Much More Fun to Drive. You Drive in and feel the Instant Difference. Care for Figo, Aspire or Freestyle 1.2 Petrol 3 Cylinder - you will find yourself in a different zone with 1.5 Litre 4 Cylinder Diesel Engine. Drive to Experience it
  • Running Cost would be lower by Rs 1.5 per km vis a vis against Petrol Car
  • Price Difference narrowed in Ecosport, Venue Sx Petrol and Sx Diesel, Creta E Model
  • Possibility of 10 year Diesel Ban not extending to other cities as Emission Level well controlled

 

Petrol Car Plus Points

  • Models where Price Gap Extended to higher amount like - Tata Altroz Petrol, Nexon Petrol are economical to tune of 1.75 Lakh on road against Diesel Model. Creta and Seltos higher up Variant where Petrol Car economical against Diesel
  • Fact of Higher Ownership Cost where Service Cost are Higher, Higher Insurance Premium Year on Year (where Ex-showroom Price is higher), Finance Interest Rates
  • Where your Average Annual Running is Low and / or belong to Delhi / NCR Zone as Petrol cars can well be driven for 15 Years
  • Where seek Light Clutch, Superior Engine NVH Levels - Petrol Cars still are better
  • Kia Seltos 1.4 Turbo, Creta 1.4 Turbo Engine feels even more responsive against 1.5 Diesel Engine

 

Net All - If you Planning for :-

  • Ford Ecosport Petrol Models
  • Hyundai Creta Base E Model
  • Hyundai Venue Sx

you need to serious give a consideration to there Diesel Engine. Infact - even if you considering Ford Figo Petrol, Aspire Petrol or Freestyle Petrol - the 1.5 Diesel Engine as used just enhances the performance to next level that Petrol Engine feels mediocre and if your average annual running is 10,000 Kms a Year and care for a Performance car - you can consider in 1.5 TDCI Diesel Engine

However, from Ownership cost Perspective

  • Tata Altroz
  • Tata Nexon 
  • Hyundai Creta Higher Up Variants
  • Kia Seltos Higher up Variants

have substantial Price Gap in Petrol and Diesel Model and in that case basis higher Ownership cost (Finance cost, Insurance Premium, Maintenance cost) - it may just be worth to go for Petrol from Financial Perspective - but trust Diesel Engine are lot more Fun to drive.

Dear Sir,
Mycarhelpline is my favourite since last 3 years, when it was lesser known and you were not on Youtube. Liked it too much and is really very useful. I have booked Freestyle Diesel Titanium just now (April 21) and was wondering about my decision. (Purely based on my choice for fun to drive and efficiency - i.e. price per Km and a go anywhere car) but after I booked and worked out the EMI etc had a feeling while comparing to Petrol option (Though in Test drive I liked both P&D) So while confused only one site name came to mind is MYCarhelpline. And Boss you sorted out my all points with an apt and TRUE comparison of Diesel and Petrol cars, especially about FOr and that too Freestyle in particular. I had test driven Kia too seltos and Sonet. Felt Sonet OK compared to Freestyle for better Boot space and slightly good features and modern things. But interior quality and fit and finish was not up to the mark of Ford Cars. ( I am using Ford Fusion 1.6 Petrol for last 14 years) and finally short listed on Freestyle Diesel. Need your comments on the decision as I have booked FS-D and sometimes I feel I did right thing for not selecting Seltos Bae model of Petrol or diesel costing 2.5 to 3 L more. Pls reply me. Thanks

Hi. After having examined many SUVs, i have short listed the following two:
a. Hyundai Venue SX1.5 Ex-showroom 10.00
b. Hyundai Venue Sport SX 1.5 Ex-showroom 10.40
c. Kia Sonet HTX 1.5 Ex-showroom 10.20

They all have sun roof.
Only Kia does not have Alloys but has LED Headlamps.

I have not driven Venue Sx as it was not avalable for test drive. Instead i as offered Creata top model (same engine) which had very responsive smooth diesel engine.
I also tried Kia Sonet diesel which i am felt had free revving up in comparison to Creata's response.

Yes. Kia has two tone interior which looks cool than the carbon black of Venue. (looks too much plastic not even like balenos leather finish plastic )

I think there is no point diesel BS6 will be out in next 5-7 years especially when its performance is quite similar to BS6 Petrol

I need advise between these three models in terms of Cost of maintenance and reliability of engine.


Regards

PS: I have also test drive Ecosport, but its clutch and gear shift was bit heavy.
WRV: Cost seems a bit on higher side and chances that honda may upgrade its model soon ( i feel so)

If both variants are same price, then i would prefer Diesel since it has more power and gives more mileage

But the show room person himself told me that the Kia/Hyundai diesel engine fuel efficiencies are not like other diesel engines (like Tata or Ford) they give very normal average around 14-15 only on highway for diesels. So ask if you know someone using it (Do not go as per youtubers) and double check if you're buying diesel only for better average

Ecosport 1.5 L Petrol fuel efficiency is very poor for my ecosport. Go for Diesel as suggested in this comparison. Very rarely you get fun to drive and economy together in a really good handling car

Dear Gagan,
Great comparison. However we now need to take two more factors into consideration. 1. 10 year limit for diesel 2. The narrowing gap of the two fuels.
With all this I would request your comment on the purchase of a new car. It will be important to note that my average running is approx 45000 km/ year. It is this running which has confused me.
I prefer to drive and have been doing 1000 km in a day very often. The need to use a car is due to uncertain programs and the reservation issues at short notice.
Thanks
Hemant
