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.
