The Hyundai i20 has always been one of those clever hatchbacks that punches far beyond its weight class. But if there’s one element that truly defines its character, performance, and long-term running costs, it’s the engine sitting under that compact bonnet. Today, we’re breaking down every Hyundai i20 engine size across generations, what each one feels like on the road, how they behave in real-world driving, and which one might suit your daily rhythm best.

Think of this as the kind of guide we’d share with a friend over coffee—only with more detail, deeper insight, and plenty of those metaphors and comparisons that make big topics feel easy and fun. So, let’s pop the hood together.

Understanding the Hyundai i20 Engine Landscape

Before we dive into specific engine sizes, let’s create a quick mental map. Across generations, the i20 has used:

• 1.0-litre petrol turbo engines
• 1.2-litre naturally aspirated petrol engines
• 1.4-litre petrol and diesel engines (older models)
• 1.5-litre diesel engines (select markets)
• 1.25-litre petrol engines (first gen)

Each one brings its own flavour—like choosing between espresso, cappuccino, or a long latte depending on how you plan to start your day.

Hyundai i20 Engine Size by Generation

Second Generation (2014–2020)

This era introduced refinement, efficiency, and modern tech into the i20 ecosystem.

Third Generation (2020–Present)

Here, Hyundai shifted toward compact turbo engines and mild-hybrid capability, meeting global efficiency standards while still keeping the fun alive.

1.0-Litre T-GDi Turbo Engine (Newer Generations)

What Is It?

A compact, three-cylinder, turbocharged petrol engine available in several power outputs (typically 100 PS or 120 PS).

How Does It Feel?

Think of it like a terrier—small but eager, lively, and surprisingly powerful. On city streets, the 1.0 T-GDi responds quickly thanks to its turbo boost, giving you effortless acceleration even at low speeds.

Why It Works So Well

• Excellent fuel efficiency
• Punchy mid-range torque
• Available with 48V mild-hybrid technology
• Great for mixed city and motorway use

Ideal For

Drivers who want balance: fun, efficiency, and smooth performance.

1.2-Litre MPi Petrol Engine (Most Popular Non-Turbo Option)

What Is It?

A naturally aspirated four-cylinder engine found in many European and Asian markets.

Road Character

Smooth, predictable, and calm—like a Sunday morning drive with no rush. It won’t pin you to the seat, but it will get you where you want to go without any drama.

Why It Stands Out

• Low maintenance
• Simple engineering
• Affordable running costs
• Ideal for new drivers or city-heavy use

Power Output

Roughly 75–84 PS, depending on region and year.

1.4-Litre Petrol Engine (Older Generations)

Personality Check

This one feels like a dependable old friend—steady and reliable. It’s not meant for spirited cornering, but it has enough muscle for long-distance comfort.

Where It Appeared

Widely offered in the first and second generations.

Strengths

• Smooth mid-range
• Excellent reliability record
• Suitable for motorway commuters

1.4-Litre CRDi Diesel Engine

The Diesel Workhorse

The 1.4 CRDi is built for efficiency first. If you’ve ever driven long stretches of motorway or love high-mileage value, this diesel engine is likely your match.

Why Drivers Love It

• Outstanding fuel economy
• High torque for hills or fully loaded driving
• Long engine life

Weaknesses

• Not the most refined engine sound
• Diesels may be restricted in future emissions zones

1.5-Litre Diesel Engine (Select Markets)

The Torque Champion

The 1.5 diesel is like a quiet weightlifter—capable, strong, and surprisingly smooth. This engine shines when carrying passengers or luggage.

Perfect For

Ride-sharing drivers, high-mileage travellers, or anyone who loves efficiency with substance.

1.25-Litre Kappa Petrol Engine (First Generation)

Charmingly Simple

The 1.25 engine helped launch the i20’s early popularity thanks to its fuss-free design and light running costs.

Pros

• Very reliable
• Cheap to maintain
• Great for new drivers

Cons

• Low power output
• Less suitable for steep motorway inclines
