Kia EV4 Fastback (UK) The Electric Coupe-Sedan.

Kia EV4 Fastback (UK) The Electric Coupe-Sedan That Might Just Shake Up the Family EV Market

The UK electric car market is getting crowded fast, but few upcoming models are creating as much curiosity as the new Kia EV4 Fastback from Kia. Sitting between a sleek saloon and a coupe-inspired fastback, it’s designed to tempt drivers who want EV practicality without falling into the usual SUV shape.

And yes it’s shaping up to be one of Kia’s most design-led EVs yet.

Design: “Concept car for the road” energy

The EV4 Fastback takes Kia’s latest “Opposites United” design language and stretches it into something more dramatic than practical. Expect:

Low, elongated fastback silhouette
Sharp LED lighting signatures (front and rear “star map” style)
Hidden rear door handles for a cleaner coupe profile
Aerodynamic wheels designed to maximise range
A noticeably long tail section improving boot capacity vs hatch rivals

It’s clearly aimed at drivers who think the EV6 is great… but a bit too SUV-like.

Battery & Performance (Expected UK Specs)

While official UK final specs may still vary, the EV4 is expected to follow Kia’s proven EV platform strategy (similar to EV3 / EV5 direction).

Likely configuration:

Single motor (RWD) – standard range focus
Dual motor (AWD) – higher trims (GT-Line style variants)

Expected battery options:

~58 kWh usable (entry range model)
~81 kWh usable (long-range version)

Estimated range:

Around 250–350 miles (WLTP) depending on trim and wheel size

Performance estimate:

0–62 mph: ~7.5s (single motor)
~5.5s (dual motor AWD)

Fast enough for UK motorway overtakes, efficient enough for long A-road cruising.

UK Trims (Expected Line-Up)

Kia typically keeps things simple, and the EV4 Fastback should follow suit:

1. Air (Entry Trim)

Standard range battery
18” alloy wheels
Minimalist interior with dual digital displays
Heat pump likely included as standard
Fabric seats with sustainable materials

2. GT-Line

Sportier body styling
19” wheels
Upgraded ambient lighting system
Heated steering wheel & seats
Larger infotainment interface

3. GT-Line S / Performance Variant (Expected top spec)

Dual motor AWD option
Premium sound system (Harman Kardon expected)
Ventilated seats
Advanced driver assist package
Glass roof / panoramic roof option

Interior: Kia’s tech-heavy comfort zone

Inside, the EV4 Fastback is expected to continue Kia’s digital-first approach:

Dual panoramic display (driver + infotainment merged look)
Over-the-air updates
Minimal physical buttons
Sustainable materials (recycled plastics, vegan leather options)
Sliding centre console storage (Kia’s clever modular design system)

One of the most interesting expected features is rear-seat optimisation for long legroom, despite the sloping roofline Kia is clearly trying to prove coupe EVs don’t have to be cramped.

Colours & Unusual Options

This is where Kia usually gets bold, and the EV4 Fastback is expected to continue that trend.

Standard colours:

Glacier White
Midnight Black
Steel Grey
Deep Blue

More expressive options:

Matte Graphite (premium option)
Sunset Copper (design highlight colour)
Electric Green accent packages (GT-Line styling packs)

Unusual touches:

Contrasting roof options (black or dark grey)
Colour-accent interior stitching depending on exterior paint
Pixel-style ambient lighting themes synced with drive modes

Boot Space & Practicality (Why fastback matters)

The whole point of a fastback EV is to combine style with usability.

Expected advantages:

Larger boot opening than traditional saloons
Deep cargo floor for luggage flexibility
Fold-flat rear seats
Estimated boot capacity: ~450–500 litres range

And this is exactly where things get interesting…

Estimated UK Price (What to Expect)

While official pricing is not final, the EV4 Fastback is expected to sit between EV3 and EV6:

Entry Air model: ~£35,000–£38,000
GT-Line: ~£40,000–£45,000
Top spec AWD: ~£47,000–£52,000

This positions it directly against:

Tesla Model 3
Polestar 2
Hyundai Ioniq 6

Final Thoughts: Why the EV4 Fastback matters

The EV4 Fastback isn’t just another electric car it’s Kia experimenting with emotion in a segment dominated by efficiency. It’s low, aerodynamic, tech-heavy, and designed for people who want something different from the usual SUV crowd.

If Kia gets the pricing right, this could easily become one of the most talked-about EV launches in the UK.

And if you’re curious about real-world practicality, especially boot space in real centimetres rather than marketing claims don’t miss my YouTube video breakdown.
