MINI Convertible Review (2004–)

Subcompact Convertible (originally launched 2004)

MINI UK review Since 2004 By the True Motion Auto editorial team

1. Vehicle Overview

The MINI Convertible, first introduced in 2004, is the open-top version of the iconic MINI Hatch, offering the same retro-inspired charm and agile handling — with the added joy of open-air driving.

For 2025, the Convertible continues as one of the few small soft-top cars still on sale, retaining its premium build quality, playful character, and everyday usability. Based on the current MINI Hatch (F66) platform, it’s offered exclusively with petrol engines for now, though an electric Convertible (based on the Cooper SE) is expected to launch later in 2025.

Compact, stylish, and surprisingly refined, the MINI Convertible remains the benchmark subcompact cabriolet, balancing fun and functionality like no rival can.

The MINI Convertible combines classic MINI design cues with elegant open-top proportions. It remains instantly recognizable yet refreshed for 2025 with subtle tweaks:

Signature round LED headlights and hexagonal grille

Union Jack LED taillights

Optional black contrast roof and mirror caps

17- or 18-inch alloy wheels

Chrome or Piano Black styling packs

Electrically folding soft-top roof available in black or MINI Yours pattern

Roof-down, the Convertible looks sporty and chic; roof-up, it retains the MINI’s distinctive hatchback silhouette.

4. Interior, Comfort & Materials

Inside, the Convertible mirrors the 2025 MINI Hatch’s minimalist, high-tech design, infused with tactile materials and fun details.

Key highlights

Digital driver display behind steering wheel

Retro toggle switches for roof and drive modes

Despite its compact footprint, the cabin feels solid and premium — a signature MINI trait.

5. Features & Infotainment

9.4-inch circular OLED display (touch and voice control)

Wireless Apple CarPlay & Android Auto

Hey MINI” voice assistant with animated MINI avatar

Built-in navigation with live traffic

Driving modesGreen, Core, Go-Kart

Optional Harman Kardon sound system

As with the Hatch, the Convertible includes a full suite of advanced safety features:

Automatic Emergency Braking (AEB)

Lane Departure Warning

Blind Spot Monitoring

Adaptive Cruise Control (with Stop & Go)

Parking Assist Plus and 360° camera

Rear Cross-Traffic Alert

The rigid reinforced frame and roll-over protection bars ensure strong occupant safety, even with the open roof.

7. Driving Performance

The MINI Convertible stays true to the brand’s legendary go-kart handling.

Precise steering, tight chassis control, and short wheelbase deliver fun, agile dynamics.

The 1.5L Cooper offers relaxed cruising, while the 2.0L Cooper S adds punchy mid-range power.

The JCW transforms it into a mini sports car, with 231 hp and engaging cornering.

Even with the extra weight from the roof mechanism, the Convertible feels lively and planted — one of the most engaging small cabriolets you can drive.

The smartest approach is to decide what matters most - comfort, space, efficiency, performance, image or technology - then compare the exact trim against two or three rivals on the same route and the same finance basis.
