Petrol Cars - FAQs
Diesel engines are costly to manufacture as they have to endure the extremely high compression pressures that are required to combust the fuel. A catalytic converter aside, petrol cars usually don't need any additional hardware to keep tailpipe emissions in check, further reducing costs.
Petrol engines in high-performance cars use high-precision direct injectors to spray fuel as and when required, combining variable valve technology and modern turbochargers to extract as much power as possible throughout the combustion sequence and engine RPM.
Almost all modern diesel engines in passenger cars feature a turbocharger to optimise performance and reduce emissions. Similarly, many modern petrol cars are offered with turbocharged engines with either direct injection or multi-point fuel injection. While the latter is cheaper, direct-injection technology often delivers more power and superior fuel economy when comparing similarly sized petrol engines. It also allows a more precise quantity of fuel to be introduced into the engine at the exact moment it is needed for optimal combustion, preventing fuel wastage and boosting efficiency. However, since diesel engines rely on compression ignition, a similarly sized diesel engine will usually deliver higher fuel efficiency.
Trending Questions on Cars - Answered by Autocar Experts
Hi Autocar Team, I am planning to buy my first car and am confused between the Mahindra XUV 3XO RevX A MT Petrol and the Maruti Suzuki Brezza ZXi+ Turbo MT Petrol. I feel the Brezza offers better value for money, more features, and is actually priced lower than the 3XO. At the same time, I understand that the Brezza offers better reliability, fuel efficiency, and long-term peace of mind. However, the 3XO feels more premium and, from what I have heard, offers a better ride quality. I plan to keep the car for 10 years or more, so long-term ownership is an important factor. Could you please suggest which of these two would be the better choice for my requirements?
Maruti Suzuki BrezzaMahindra XUV 3XOI am a 21-year-old college student. We currently have a 2025 Mahindra XUV 700 at home for family trips, outings, and weekend drives. However, I require a second car (preferably a non-SUV) for daily city commutes, easy parking, and college use. My budget is below Rs. 12 lakh, and I do not want an EV.
Maruti Suzuki BalenoBeing a Maruti Suzuki customer for 15 years now and I am very much used to hassle free ownership considering Brezza ZXI+ Petrol AT NA engine compared to TCMPFI AT in 3XO or Nexon DCA (dropped due to DCA). However, considering upfront extra cost for Brezza coupled with smart hybrid replacement possibility and no spare wheel, I am simply unable to convince myself to go for Brezza top variant as I like 360 camera feature. With my congested traffic city driving around 500-800 km per month, will it be still worth to pay additional 2.30 lakh rupees compared to any car in segment, only for Maruti Suzuki brand especially when competition is offering so much more for such a lesser price than Brezza top variant. Lesser mileage costs also gets compensated for any turbo engine with lesser purchase cost than Brezza.
Maruti Suzuki BrezzaMahindra XUV 3XOMy current car is a Toyota Etios Petrol, and I am planning to upgrade to a D-segment SUV. My on-road budget is Rs. 30 lakh. My usage is very low, as I do not drive daily. I drive occasionally during the week, with a total running of around 20-30 km per month, along with a few long trips each year. Considering the current E20 petrol scenario, should I buy an EV or continue with a petrol SUV? I also have the facility for home charging.
Mahindra XEV 9STata Sierra EVI'm looking for your expert opinion to help me finalise my next used family car. I'm currently considering the MG Hector Plus Sharp Pro 1.5 Turbo Petrol MT (2024), Hyundai Alcazar 2.0 MPI Petrol, Kia Carens 1.5 Naturally Aspirated Petrol, and Maruti XL6 Alpha Plus Petrol. My usage is around 500 km per month (approximately 6,000 km per year), with most of my driving being in the city. My family consists of four members, and while I rarely need the third row, having a 6- or 7-seater is a bonus for occasional family trips. I plan to keep the car for at least 7 to 10 years. Fuel economy is not a priority; instead, I value comfort, features, reliability, and good performance. Long-term dependability, ease of maintenance, and a hassle-free ownership experience are far more important to me than mileage. One of my biggest concerns is the increasing use of ethanol-blended petrol, with E20 already in use and the possibility of higher blends such as E30 in the future. I'm unsure whether I should avoid turbo-petrol engines for long-term ownership or whether modern turbocharged engines are reliable enough. Based on my usage, which of these four cars would you recommend? Would you choose a naturally aspirated engine, such as those in the Alcazar, Carens, or XL6, over the MG Hector's 1.5-litre turbo-petrol for someone planning to keep the vehicle for 7 to 10 years? How concerned should I be about E20 or future E30 fuel and its long-term impact on these engines? Is the MG Hector's 1.5 Turbo Petrol engine dependable enough for long-term ownership, or would you prefer the Hyundai 2.0 MPI or the other naturally aspirated options? Is the Kia Carens 1.5 NA petrol sufficiently powerful for occasional trips with six or seven passengers, or is it likely to feel underpowered? Similarly, is the Maruti XL6 Alpha Plus adequately powered for highway driving with a full load, or does its 1.5-litre mild-hybrid engine struggle in such conditions? Finally, how would you rank these four cars in terms of long-term reliability, performance (especially when fully loaded), build quality and safety, maintenance costs, service network, feature list, and overall ownership experience? If this were your own long-term family car purchase, which one would you choose and why? I'd really appreciate an unbiased recommendation based on my specific requirements rather than general market popularity. Thank you!
