Kia Rio 1.4 Diesel 2017 Complete Review: Economy, Space, Ride

The 2017 Kia Rio 1.4 diesel enters the crowded supermini market with promises of exceptional fuel savings and low emissions, targeting high-mileage drivers. This model balances practicality and affordability, though it struggles to match the dynamism of top competitors.

Engine Performance and Efficiency Breakdown

At the heart of this Rio variant sits a 1.4-liter CRDi diesel engine delivering 89 horsepower and 240Nm of torque. It awakens briskly from around 1,500rpm, providing solid in-gear acceleration for overtaking and merging. Official figures claim 74.3mpg combined economy and 98g/km CO2 emissions, making it a standout for company car users or those prioritizing running costs.

However, power fades sharply beyond 3,000rpm, accompanied by audible clatter under hard acceleration. This contrasts with smoother petrol alternatives like Kia’s own 1.0-liter T-GDi, which offers better flexibility across revs. Paired with a six-speed manual gearbox, shifts are precise, helping maintain momentum in the engine’s narrow sweet spot.

• Torque delivery: Strong low-end pull ideal for urban and motorway cruising.
• Top-end weakness: Lacks urge when revved high, unlike some rival diesels from Citroen or Mazda.
• Fuel reality: Achieves high-70s mpg in mixed driving, per tester reports.

Driving Dynamics: Handling and Ride Assessment

On twisty roads, the Rio feels composed with direct steering, though it lacks the sharp feedback of a Ford Fiesta. The diesel’s added weight slightly dulls turn-in compared to petrol siblings, but everyday stability remains predictable.

Ride quality draws criticism: it’s jittery over urban potholes and harsh on uneven surfaces, with noticeable suspension thumps and elevated road noise versus a VW Polo. Body control suffices for spirited drives, but the overall package feels less polished than segment benchmarks.

Interior Comfort and Practicality Highlights

The cabin impresses with generous space for front and rear passengers, surpassing many peers in rear legroom and boot capacity. Materials mix soft-touch surfaces with harder door plastics, creating a functional but not premium ambiance.

Higher trims like ‘3’ spec include a 7-inch touchscreen supporting Android Auto and Apple CarPlay, heated seats, faux leather, and climate control—generous for the price. Visibility aids easy maneuvering, and the 325-liter boot expands usefully with 60/40 split-folding seats.

• Seating: Supportive fronts, ample rear space for adults.
• Storage: Deep door bins, large glovebox.
• Tech: Intuitive infotainment, though base models skimp.

Design and Exterior Styling Analysis

Kia’s fourth-generation Rio adopts a mature, understated look with sleek lines and a bold grille. Sixteen-inch alloys on mid-spec models add poise, but the silhouette lacks flair next to edgier rivals. LED daytime lights enhance modernity without excess.

Build quality appears solid, backed by Kia’s industry-leading seven-year warranty, boosting buyer confidence.

Running Costs and Ownership Experience

With sub-100g/km emissions, the diesel qualifies for low Benefit-in-Kind tax, appealing to fleet buyers. Insurance groups hover low (around 12-15), and servicing intervals stretch to 20,000 miles or yearly. Resale holds firm thanks to warranty coverage.

Petrol 1.0 T-GDi variants edge it for all-round use, blending 60+mpg with quieter operation. Consumer feedback praises reliability and economy, with few major issues reported.

Safety and Reliability Considerations

Standard safety kit includes stability control, multiple airbags, and hill-start aid. Euro NCAP awarded five stars, though active tech like autonomous braking was optional. Long-term owners report rock-solid durability, aligning with Kia’s reputation.

Market Positioning Against Competitors

Priced keenly from £16,000, the Rio undercuts some rivals while matching kit levels. It trails Ford Fiesta in fun-factor and VW Polo in refinement but leads in space and warranty.

• Strengths vs. rivals: Efficiency, space, value.
• Weaknesses: Ride, engine noise, excitement.
