These days, instead of wondering which car engine is the best, it is a better idea to go for what is renowned as the most efficient and reliable petrol engine in the segment when you plan to buy a car.

Come meet the K-Series line-up of petrol engines which have created benchmarks on all these fronts.

The History of the Most Reliable Petrol Engine in India

If you had asked which car has the best engine back in 2008, the answer would have been the all-new A-Star that was then launched fitted with the very first K-series engines by Maruti Suzuki. The engine was a Euro IV and V compliant, 1L “green engine”.

Ever since then, Maruti Suzuki has been consistently working towards enhancing its powertrains. Today, the K-series engines embody the global design trend with their innovative design technique that perfectly optimises engine performance.

What Makes K-Series the Most Efficient Petrol Engine in India?

K-series engines promise superior NVH (Noise, Vibration, and Harshness) performance, best-in-class fuel efficiency, and a smooth driving experience. The engines have a crisp throttle response that ensures linear power delivery and an unmatched drive. Here are the three key features of these engines: -

• Reliable

The engines are rigorously tested over time and go through lakhs of kilometres of testing to ensure that they can deliver optimum performance. About 6.3 million K-Series engines have already been sold by Maruti Suzuki, which are fitted in cars across all segments.

• Efficient

K-Series engines are equipped with a refined gasoline engine technology for fuel efficiency and performance; silent timing chain and improved engine stiffness for better NVH characteristics; and an SDLI (smart distributor less ignition) system with advanced injectors and dedicated plug top coils for optimised and uniform combustion.

• Great Mileage

The all-aluminium engines include innovative rocker-less DOHC cam shafts, offset crank shafts with low tension rings, and plastic intake manifolds. They also have enhanced thermal efficiency and higher compression ratios. All of these together ensure great fuel efficiency. Using advanced low friction oils for the engine helps to further enhance efficiency.

A Step Towards Green Mobility

Other features that contribute to enhanced fuel efficiency are the dual VVT, dual injectors, cooled EGR, and higher compression ratios that the K-Series engines are well-known for. Apart from the mileage, these features also help in lowering engine emissions which, in turn, contribute a lot to green mobility.

BS6 Compliance

BS6 engines must adhere to the stricter emission norms which require a substantial reduction of almost 25% in NOx (nitrogen oxide) emissions. For that purpose, K-series engines by Maruti Suzuki have been upgraded and fine-tuned to ensure that they meet these stringent requirements.

Engineered to be the most reliable and efficient, K-Series engines can run on both BS4 and BS6 fuels. Further, these petrol engines have been rigorously tested in actual Indian driving conditions to ensure that they are not only able to deliver optimum performance but also contribute to a greener and sustainable mobility.
