The Hyundai i20 Blue stands out in the competitive small car segment by prioritizing fuel efficiency and low emissions without sacrificing everyday usability. This diesel-powered model delivers official figures of 76.4mpg combined and just 98g/km CO2, making it Hyundai’s greenest offering and a smart pick for budget-conscious commuters.

Engine and Performance Breakdown

At the heart of the i20 Blue is a 1.4-liter CRDi diesel engine producing 90 horsepower and 220 Nm of torque from as low as 1,750 rpm. Paired with a six-speed manual transmission, it provides adequate pull for urban and highway duties. Reviewers note its smooth operation around town, aided by an Intelligent Stop & Go system that shuts off the engine at junctions to save fuel.

Acceleration is modest, with 0-62mph in around 12.9 seconds, but the low-end torque ensures effortless merging and overtaking. The turning circle of 10.2 meters enhances maneuverability in tight spaces, ideal for city parking.

  • Power: 90 bhp
  • Torque: 220 Nm @ 1,750 rpm
  • Transmission: 6-speed manual
  • Top Speed: 109 mph

Fuel Economy and Emissions Excellence

The i20 Blue’s eco credentials shine brightest here. Technologies like low rolling-resistance tires, aerodynamic wheel deflectors, and ISG contribute to a 12g/km CO2 reduction over standard i20 diesels, hitting 98g/km. This exempts it from road tax and London Congestion Charge, boosting appeal for urban drivers.

Official economy reads 68.9mpg urban, 76.4mpg combined, and over 80mpg extra-urban. Real-world tests confirm around 755 miles per full tank, costing about £63 to fill—exceptional for a supermini.

Design and Dimensions Overview

Measuring 4,035mm long, 1,474mm high, and with a 2,570mm wheelbase, the five-door hatchback offers a practical footprint. It seats five comfortably, with 301-352 liters of boot space expandable to 1,165 liters.

Exterior styling is clean and modern, available in shades like Meta Blue. Alloy wheels and subtle eco badging distinguish the Blue variant. The wheel-at-each-corner layout aids stability and parking ease.

Interior Comfort and Practicality

Inside, the cabin prioritizes function with air conditioning, Bluetooth, USB port, electric windows, and mirrors as standard. Higher trims add a CD/MP3 player. While some hard plastics feel budget-oriented, assembly is solid without rattles.

Rear space accommodates adults for short trips, and the boot swallows weekly shopping. An eco-driving indicator on the dash encourages efficient habits.

Driving Dynamics and Handling

The suspension strikes a balance: firm enough for composed cornering yet absorbent over potholes. It’s nimble in traffic, with taut European-tuned dynamics. Not sporty like a Ford Fiesta, but reliable for daily commutes.

Steering is precise, and the ride suits mixed roads. Noise levels are low on motorways, though wind rush is noticeable at speed.

Running Costs and Ownership Perks

Priced around £13,195-£13,600 OTR, it’s cheaper than rivals like the Fiesta Econetic (£15,190), with better whole-life costs at 35.1ppm versus 35.5ppm. Residual values sit at 28%, and BIK tax benefits persist post-2017 changes.

Hyundai’s five-year unlimited mileage warranty, including roadside assistance and health checks, adds peace of mind. Low insurance groups and fuel savings keep costs down.

Safety and Reliability Features

Standard safety includes ABS, stability control, and multiple airbags. A catalytic converter ensures emissions compliance. Hyundai’s reputation for durability shines, backed by the long warranty.

Competitor Comparison

Versus the Ford Fiesta Econetic: i20 Blue wins on price and costs but trails in residuals and refinement. Toyota Yaris hybrids offer better mpg but higher upfront costs. VW Polo provides premium feel with less boot space.
