2021 Mini Convertible MODEL OVERVIEW


  • Not too windy with top down
  • Fun driving experience
  • Quiet with the roof up


  • Tiny back seat and trunk
  • Ergonomic mishaps
  • Gets expensive quickly

The Mini Cooper Convertible is exactly what it sounds like—a drop-top version of the BMW-owned British automaker's iconic small hatch. Mini introduced the current-generation Cooper for the 2014 model year, and the convertible came two years later for 2016. It competes with other affordable convertibles including the Mazda MX-5 Miata, Fiat 124 Spider, Ford Mustang, and Chevrolet Camaro.

The Mini John Cooper Works Convertible is a 2021 IntelliChoice Best Overall Value winner.

What's New

  • Navigation and Apple CarPlay now offered on Signature

What We Think

Our first impressions of the Mini Convertible were strong ones. This is a car that feels much more solidly built than the vehicle it replaces, swapping that car's constant rattling with a newfound feeling of quality. That feeling is backed up by rich leather upholstery.

Top up, the convertible is plenty quiet, and with the roof retracted, wind turbulence in the cabin is held to a minimum. We did have some ergonomic nitpicks, though. The infotainment controller placement requires an uncomfortable kink in the wrist, and the parking brake runs up against the center armrest. Oh, and don't plan on carrying much in terms of rear passengers or cargo.

Driving the Mini Convertible, the steering is twitchy and quick, and body control is excellent. There's plenty of grip, too, and the traction control system helps put power down without feeling intrusive. This car can carry serious pace. If you dig the retro-cute design and can look past a couple of ergonomic mishaps and the price you pay for style, the Mini Convertible could be a great drop-top.

Performance and Fuel Economy

All Mini Convertibles feature FWD, and although most include a seven-speed dual-clutch automatic transmission, Mini has brought back a six-speed manual option for Cooper and Cooper S variants. Higher trim models work with four-cylinder power, but the base Mini Cooper Convertible receives a 1.5-liter turbocharged inline-three. It develops 134 hp and 162 lb-ft of torque which results in 0-60 in a claimed 8.2 seconds. In terms of fuel economy, the Cooper Convertible is EPA-rated at 26/37 mpg city/highway with the manual and 28/37 mpg with the dual-clutch.

The Cooper S and John Cooper Works convertibles both feature a 2.0-liter turbo I-4. It develops 189 hp and 207 lb-ft of torque in the Cooper S or 228 hp and 236 lb-ft in the JCW. Mini estimates 6.7 seconds to 60 in the Cooper S, and the John Cooper Works model can accomplish the same in 6.3 seconds. Fuel economy measures 23-26/32-34 mpg in the manual and automatic Cooper S or 25/33 mpg in the JCW.


Mini includes its Active Driving Assistant as standard on all trims of the Cooper Convertible, meaning forward collision warning and automatic emergency braking are included on every model. An available Driver Assistance package adds front parking sensors, auto parking assistant, and adaptive cruise control.

Cargo Space and Interior Room

This being a Mini—and a two-door, at that—its cabin is pretty tight. The Cooper Convertible seats just four, with a respectable 41.4 inches of legroom up front but just 30.9 inches for those crammed in the back. Cargo capacity measures a tiny 5.7 cubic feet behind the rear seat, and even though you can fit 7.6 cubes' worth of cargo with the seats folded down, we wouldn't recommend trying to move anything much larger than a shoe box.


Classic and Signature trims of the Cooper Convertible feature a 6.5-inch touchscreen infotainment display. Wireless Apple CarPlay and navigation are available on Signature trims with the 6.5-inch screen or in Iconic models with an 8.8-inch touchscreen. Android Auto is not available. Audiophiles can upgrade the base audio system to an optional 12-speaker Harman Kardon setup.
