Hyundai I20 Blue Review: 76.4mpg Diesel Supermini

The Hyundai i20 Blue stands out in the crowded supermini segment as a diesel-powered hatchback optimized for low emissions and impressive fuel economy. Building on the reliable i20 platform, this variant introduces eco-focused tweaks like stop/start technology and low rolling-resistance tires to deliver just 98g/km of CO2, making it one of Hyundai’s greenest models available at the time.

Engine and Performance Overview

At the heart of the Hyundai i20 Blue is a 1.4 CRDi diesel engine producing 90 horsepower. This setup achieves a remarkable combined fuel economy of 76.4mpg, surpassing the standard i20 Comfort trim by 9.1mpg and reducing CO2 output by 12g/km. The engine pairs with a manual transmission, emphasizing efficiency over outright speed, with a 0-62mph time around 13.1 seconds in similar petrol variants, though diesel torque provides better low-end pull for city driving.

Drivers report a pleasant, if unremarkable, handling experience. The suspension balances comfort and stability adequately for urban and motorway use, though it lacks the sharpness of sportier rivals. Top speed hovers at 106mph, sufficient for most needs. Towing capacity reaches 910kg braked and 450kg unbraked, adding versatility for light loads.

Dimensions and Practicality

Measuring 4,035mm in length, 1,474mm in height, and with a 2,570mm wheelbase, the i20 Blue offers compact dimensions ideal for tight parking spaces while accommodating five passengers. Boot space starts at 301-352 litres with seats up, expanding significantly when folded, making it competitive for family shopping or weekend getaways.

These specs position the i20 Blue as a practical choice, with tyre sizes of 195/55 R16 on alloy wheels and a space-saver spare for emergencies.

Interior Design and Comfort

Inside, the cabin features a mix of materials, with some harder plastics in lower areas but solid overall build quality free of rattles. Modern i20 iterations include an eight-inch touchscreen, Apple CarPlay, Android Auto, and a 10.25-inch digital driver’s display across trims, elevating the experience beyond expectations for the price. Comfortable seating for five and adjustable controls enhance daily usability, though rear space is snug for taller adults on long trips.

• Standard tech: 16-inch alloys, touchscreen infotainment, smartphone integration.
• Premium upgrades: Larger screens, Blue Link connectivity.
• Build quality: Well-assembled with minimal noise intrusion.

Fuel Economy and Running Costs

Official figures boast 76.4mpg combined for the diesel Blue, with urban at 47mpg and extra-urban up to 67mpg. Real-world motorway runs yield around 50mpg in petrol cousins, suggesting strong efficiency for the diesel. Priced from £13,195, it undercuts the Ford Fiesta Econetic by nearly £2,000, offers free road tax, and maintains favorable BIK tax bands. Whole-life costs at 35.1ppm beat the Fiesta’s 35.5ppm, aided by 28.0% residual values.

Low CO2 of 98g/km crowns it Hyundai’s greenest model, even edging out the smaller i10, ideal for company car drivers or eco-conscious buyers.

Driving Experience in Detail

On test drives around urban environments like London, the i20 Blue excels in congestion zones thanks to its frugal nature, dodging charges with ease. The ride is composed over bumps, with light steering suited to parking maneuvers. It’s not a thrill-seeker’s choice but delivers reliable, undemanding motoring. Diesel refinement is good, with minimal vibration, and the stop/start system operates smoothly to preserve fuel savings.

Safety and Standard Equipment

Hyundai equips the i20 generously from entry levels. SE Connect brings alloy wheels, advanced connectivity, and safety aids like lane-keeping assist in newer models. Boot practicality shines with 352 litres expandable to 1,165 litres, surpassing some rivals like the Volkswagen Polo. Safety ratings are strong, bolstered by catalytic converters and robust construction.

Competitor Comparison

The i20 Blue leads on upfront cost and whole-life expenses, though hybrids like Yaris offer superior real-world mpg in some scenarios.

Ownership Pros and Cons

• Pros: Exceptional fuel economy, low emissions, competitive pricing, generous equipment, practical boot.
• Cons: Interior plastics feel basic, handling not class-leading, resale slightly trails premium rivals.

Despite minor shortcomings, the value proposition is compelling for fleet buyers or first-time owners.

Latest Updates and Availability

While the original Blue focused on diesel efficiency, current i20 lineups emphasize petrol manuals and mild-hybrids, retaining the supermini’s fun-to-drive ethos with 53.2mpg official in manuals. Pricing starts around £18,133 new, with used from £8,799 offering bargains.
