Q & A

Why is it important to understand the engine during a test drive?

It’s important because the engine is a key component of the car. If it’s not good, the joy of ownership can be completely ruined, even if other features are appealing. A proper understanding of the engine's performance, reliability, and maintenance costs is essential for a long-term positive ownership experience.

What are the top contenders in the A-segment for car engines?

The top contenders in the A-segment are the Maruti 1L three-cylinder engine (K10C) and the Maruti 1.2L three-cylinder engine (K12N). The K10C engine is preferred for its better mileage and lower maintenance costs, even though the K12N engine provides better power.

What is the biggest drawback of the Renault Kwid's engine?

The Renault Kwid’s engine has long-term reliability issues due to its plastic sump, which can break, causing the engine to starve for oil. This results in significant engine damage for some owners, although it doesn't happen to everyone.

Which engine is the best in the B1 segment for hatchbacks?

The best engine in the B1 segment for hatchbacks is Maruti's new 1.2L three-cylinder engine, found in cars like the Swift and Dzire. Despite being slightly unrefined, it offers impressive mileage (16-17 km/l in city traffic) and good performance.

What is the performance difference between Maruti's K-series engine and Honda's VTEC engine in the B2 segment?

Both engines have similar peak power outputs around 89 bhp. However, Honda's 1.2L iVTEC engine is slightly more refined and performs better over the long term compared to Maruti's K-series engine, even though Maruti offers better mileage (14-15 km/l).

What is the key feature of turbo-GDI engines in sub-4-meter SUVs?

Turbo-GDI engines, like the 1L TSI from Skoda and Mahindra's 1.2L Stallion GDI, provide higher power outputs compared to naturally aspirated engines. However, they suffer slightly in long-term reliability and maintenance due to the need for gasoline particulate filters (GPF), which can increase maintenance costs.

Why is Mahindra’s 2L mStallion engine considered one of the best in the D1 segment?

Mahindra’s 2L mStallion engine is praised for its strong performance, delivering excellent power and acceleration. With a score of 9.5 out of 10 for performance, it is recognized as one of the best petrol turbo engines in the D1 segment, especially due to its fast acceleration.

What are the main advantages of Toyota’s 2.4L diesel engine in the D1 segment?

Toyota's 2.4L diesel engine is known for its outstanding long-term reliability, lasting up to 7-8 lakh kilometers without noticeable issues. This, combined with good refinement and lower maintenance costs, makes it the top choice in the D1 segment for diesel engines.

What factors should be considered before purchasing a diesel car in India?

Before purchasing a diesel car, it’s important to consider the maintenance costs associated with DPF (diesel particulate filter) cleaning, especially since the introduction of BS6 Phase II. Diesel engines require highway usage of at least 30% per month to avoid DPF clogging and the associated high maintenance costs.

What is the best engine in the C-segment SUVs for GDI engines?

The best GDI engine in the C-segment SUVs is Hyundai-Kia’s 1.5L GDI engine. It offers better performance and slightly higher power compared to other GDI engines in this segment, making it the top choice for performance and refinement.
