Kia Rio 1.4 CRDi 3: 50mpg, Seven-Year Warranty

The Kia Rio 1.4 CRDi in ‘3’ specification stands out in the crowded supermini segment by blending exceptional fuel efficiency, comprehensive equipment levels, and Kia’s renowned seven-year warranty. This diesel-powered hatchback delivers real-world economy around 50mpg while offering a comfortable cabin packed with premium touches, making it an appealing option for company car drivers and private buyers alike.

Powertrain and Performance Overview

At the heart of the Kia Rio 1.4 CRDi 3 is a 1.4-litre four-cylinder diesel engine producing 89bhp, paired exclusively with a six-speed manual gearbox and front-wheel drive. This setup replaces earlier, noisier three-cylinder options, providing smoother operation and better drivability. Acceleration from 0-62mph takes 11.6 seconds in the higher-output version, with mid-range flexibility aided by the slick shifter that keeps revs in the optimal zone.

While not a thrill-seeker, the engine proves competent for urban commuting and motorway cruising. Reviewers note its refinement, though a tall sixth gear may require downshifts on inclines. The idle stop-start system functions seamlessly, contributing to efficiency without intruding on comfort. Official NEDC figures claim 74.3mpg combined with 98g/km CO2 emissions, though real-world tests yield a respectable 50.3mpg across mixed driving.

This table highlights the Rio’s edge in acceleration and economy over key rivals, positioning it as a fleet favorite with low BIK ratings around 17%.

Design and Practicality

The Kia Rio adopts a bold, aggressive exterior with sharp lines, wide tyres, and a sporty stance that belies its supermini roots. Available solely as a five-door hatchback, it improves rear passenger access without compromising style. Dimensions provide class-competitive space: adults fit comfortably front and rear, with good legroom and headroom, though the central rear seat is firmer and narrower.

Boot capacity measures a decent size for the segment, accommodating weekly shops or weekend luggage with ease. The driving position accommodates a wide range of heights thanks to adjustable seats and tilt steering, ensuring fatigue-free journeys.

• Front space: Excellent visibility and supportive seats with height adjustment.
• Rear space: Suitable for two adults; viable for three on shorter trips.
• Boot volume: Practical for everyday use, expandable via 60/40 split-folding seats.

Interior Quality and Technology

Step inside the top-spec ‘3’ model, and the cabin impresses with sturdy build quality, clear dashboard layout, and tactile switchgear. Materials feel a cut above entry-level rivals, with soft-touch surfaces in key areas. Standard kit is generous: heated leather seats, heated steering wheel, rear parking sensors, and a user-friendly infotainment system with clear button labeling.

While not as flashy as some competitors, the functionality shines. The six-speed gearbox operates with precise, light action, and climate controls are intuitive. Higher trims add value over mid-spec ‘2’ models, which save around £2,000 while retaining core features.

Driving Dynamics and Ride Comfort

On twisty roads, the Rio handles with confidence: electrically assisted steering offers good weighting, wide tyres provide grip, and body roll is minimal. It’s stable at highway speeds, filtering wind and road noise adequately. City driving feels nimble, with soft suspension absorbing urban imperfections for a ‘fun’ experience.

However, the ride has firm tendencies. It crashes over potholes and larger bumps, transmitting imperfections into the cabin more than plusher rivals like the Ford Fiesta. Speed humps are managed, but smaller road flaws and some diesel clatter persist. Braking is strong and progressive, inspiring trust in varied conditions.

The suspension strikes a balance between comfort and control, holding the chassis firmly in corners while smoothing out most irregularities.

Running Costs and Ownership

Priced from around £17,190 (2017 P11D), the Rio offers strong residuals at 30.8% after three years, with fuel costs estimated at £4,491. Depreciation is manageable at £11,890, bolstered by the industry-leading seven-year/100,000-mile warranty. Prepaid service plans, like three years for £259, further reduce outlay.

Low emissions (92-98g/km) qualify for favorable tax bands, appealing to business users. Compared to petrol variants, the diesel excels in economy, though the 1.0 T-GDi petrol warrants consideration for livelier performance at 62.8mpg.

Rivals and Market Position

The Rio competes with Ford Fiesta, Peugeot 208, and Mazda2. It undercuts the Fiesta on price (£14,295 vs £15,095 in similar spec) and offers superior warranty and kit. Fiesta edges in ride refinement, but Rio counters with power and economy. Peugeot’s BlueHDi is thriftier, yet slower. Kia’s value proposition shines for long-term ownership.

Pros and Cons

• Pros: Outstanding fuel economy, generous standard equipment, seven-year warranty, spacious interior, slick gearbox.
• Cons: Firm ride over bumps, some engine noise, tall gearing on hills.
