2014 MINI Cooper D Review: 114Bhp Diesel, 80Mpg, Road Test

The 2014 MINI Cooper D marks a significant step forward for the brand, introducing a new-generation 1.5-liter three-cylinder turbodiesel engine that boosts power to 114bhp while maintaining 270Nm of torque. This model delivers impressive acceleration, with 0-62mph in 9.2 seconds, and exceptional fuel economy around 80mpg, paired with refined ride quality and engaging dynamics.

Engine and Performance Excellence

At the heart of the 2014 Cooper D lies a innovative 1.5-liter three-cylinder diesel unit, replacing the previous 1.6-liter four-cylinder. Despite the downsizing, output rises slightly to 114bhp, with torque holding steady at 270Nm. This engine shines in mid-range pull, providing confident overtaking and effortless hill climbs once past 1,500rpm.

Paired with a precise six-speed manual gearbox, the powertrain feels linear and responsive, free-revving without typical diesel lag. Top speed reaches 127-133mph depending on sources, making it respectable for a supermini. Real-world testing confirms smooth acceleration and quiet operation, avoiding the breathlessness of older diesels.

Drivers note the engine’s tuneful note, with minimal noise intrusion even at idle after warmup. The turbo spools efficiently, ensuring no significant drop-off during shifts.

Dynamic Handling and Ride Comfort

True to MINI heritage, the Cooper D retains its go-kart-like agility. The chassis features high grip levels, minimal body roll, and instant turn-in, thanks to advanced multi-link rear suspension. It handles bumps and camber changes with maturity, yet remains engaging on twisty roads.

Ride quality has improved markedly, softening low-speed stiffness and reducing motorway fidget. Refinement is class-leading, with distant road and wind noise, approaching family hatch levels. Steering is direct and communicative, though some critique its lack of weight at high speeds.

• Cornering prowess: Light on its feet, rewarding with balance and feedback.
• Ride balance: Compliant over rough surfaces without sacrificing sportiness.
• Highway stability: Quiet and composed at speed.

In sport mode (optional), throttle sharpens and steering weights up, enhancing the zippier feel. Overall, it elevates supermini standards with expensive-feeling engineering.

Interior Design and Practicality

Larger dimensions—98mm longer and 44mm wider than its predecessor—provide a more premium cabin infused with BMW-sourced tech. Materials feel upscale, with customizable trims elevating ambience.

Front seating offers ample space and support, but rear is tight, best for children. Boot capacity is 211 liters, improved but limited; folding seats help. Standard kit includes Bluetooth, DAB radio, and air-con, with extensive personalization options.

Tech highlights: Intuitive infotainment, quality switchgear, and quirky details like offset pedals that demand adaptation. It’s a tech lover’s dream, blending fun with functionality.

Fuel Efficiency and Running Costs

Official figures claim 80.7mpg combined and 92g/km CO2, earning high green ratings. Real-world returns around 50-60mpg, better than rivals, aided by stop-start. At £16,450, it’s premium-priced but justified by equipment and dynamics. Low emissions suit urban tax bands.

Safety and Reliability Insights

While specific 2014 Cooper D crash data varies, the platform scores well in Euro NCAP tests for similar MINIs, with strong adult protection. Diesel models benefit from efficient braking and stability systems. Reliability is solid, backed by BMW engineering.
