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
Dear Autocar team, I am planning to buy a petrol automatic SUV priced under Rs 20 lakh. I have been considering the Tata Sierra petrol automatic but am concerned about Tata's after-sales service. My key requirements are comfortable seating for four to five adults, a spacious midsize SUV rather than a compact SUV, strong safety standards and build quality, and modern features such as a 360-degree camera. Which options should I consider?
Tata SierraKia SeltosHyundai CretaI'm planning to buy a new car with an on-road budget of up to Rs. 30 lakh in India. I want a car that offers excellent comfort, low running costs, and a relaxed driving experience for my daily commute. 1. My Driving Profile -Average monthly driving: 2,500 km -Driving conditions: 60% suburban roads and Highway and 40% city traffic -Long-distance trips: One or two trips per month -Current car: 2017 Maruti Suzuki Baleno, manual transmission 2. Comfort and Ergonomics I'm approximately 6 feet tall and currently experience fatigue and leg pain during my daily commute in my manual Baleno. My top priority is to find a car with: -An automatic transmission for easier driving, especially in traffic. -Excellent front-seat comfort and adequate legroom. -Good driving posture, lumbar support, and adjustable seating. -A comfortable suspension setup for daily commuting and long journeys. -Low cabin noise and minimal driver fatigue. 3. Running Costs and Powertrain -Low running costs and excellent overall energy efficiency are important. -I have charging facilities available at home, so I'm open to considering an electric vehicle (EV). -I'm also willing to consider petrol, diesel, or hybrid vehicles if they offer better overall value. -I want to compare energy or fuel costs, maintenance, insurance, and long-term ownership costs. 4. Family Requirements -The car will primarily be used for my daily commute. My family occasionally travels with me, so rear-seat comfort is also important. -I'm open to both 5-seater and 7-seater options, provided the car meets my comfort and cost requirements. 5. Budget and Ownership -Maximum on-road budget: Rs. 30 lakh -I want a reliable car that offers good value for money over long-term ownership. -I plan to use the car for several years, so durability, battery longevity (for EVs), resale value, and total cost of ownership matter. Please suggest a car.
Hyundai Creta ElectricMaruti Suzuki BalenoKia SeltosHi Autocar, For naturally aspirated (NA) petrol manual cars, which models offer the best real-world mileage, especially for city driving in the NCR? Also, could you provide the price range of these cars?
Maruti Suzuki BalenoMaruti Suzuki SwiftMaruti Suzuki DzireMaruti Suzuki BrezzaHi Autocar Team, I own a Maruti Suzuki Grand Vitara AT (non-hybrid) and spend around Rs. 12,000-14,000 per month on petrol. Its city mileage has dropped from around 13 kmpl to 10 kmpl. I also have solar panels at home, so EV charging would be almost free or cost a maximum of Rs. 3-4 per unit. I am confused about whether I should replace the Grand Vitara with an EV or keep it and buy a Tata Tiago EV for daily city use. Am I thinking too much about fuel savings? Should I simply keep the Grand Vitara and avoid buying a second car altogether? I would like to hear from people who have been in a similar situation. What makes more financial sense in the long run?
Maruti Suzuki Grand VitaraTata Tiago EVKia Syros EVHyundai Creta ElectricKia Carens Clavis EVMG Hector Tomahawk EVHi Autocar Team, I am currently driving a Hyundai Elite i20 Asta petrol manual. So far, I feel it is the best-designed car in its segment, offering great comfort and mileage that varies depending on traffic conditions. I was wondering if I could give it a facelift by replacing the front section with that of the new-generation i20. My second thought is whether I should wait for the new Hyundai Bayon or if a facelifted Hyundai i20 or Hyundai Verna is expected. I find the rear design of the new-generation i20 disappointing, and I still feel that the Elite i20 I currently own is the best-looking version. What are your thoughts?
