BMW 125i SE Convertible Full Review, Specs, 218 HP

The BMW 125i SE Convertible captures the essence of open-air motoring with its rear-wheel-drive layout, potent straight-six engine, and compact yet elegant design. Priced around £26,200 when new, this model offers a compelling mix of performance, style, and usability that makes it stand out in the premium convertible segment.

Striking Exterior and Clever Roof Mechanism

Measuring 4,360mm in length, the BMW 125i SE Convertible is surprisingly spacious for its class, surpassing the dimensions of earlier 3-Series drop-tops. Its narrower and lower profile compared to competitors like the Audi A3 Cabriolet gives it superior proportions and a more athletic stance. The large headlamps contribute to a distinctive BMW face that appears compact and purposeful.

The soft-top roof is a highlight, folding neatly under a hard cover in 22.7 seconds—operable up to 31mph for on-the-move convenience. While not the quickest (Audi manages it in 9.6 seconds), it maintains a clean silhouette when stowed and includes a raisable compartment for extra boot space. This design appeals to purists who prefer fabric over metal hardtops, echoing the charm of classic cabriolets.

• Boot capacity: 260 litres standard, expandable to 305 litres with roof up
• Roof operation time: Approximately 20-23 seconds
• Full four-seater layout with decent rear access

Premium Cabin Built for Comfort and Control

Inside, the 125i SE Convertible boasts high-quality materials and thoughtful ergonomics typical of BMW’s entry-level luxury. The driving position is exemplary, with supportive seats featuring optional leather that resists heat buildup in sunny conditions—a practical touch for drop-top owners. Instruments are clearly laid out, and standard features like parking sensors, rain-sensing wipers, and heated seats enhance everyday usability.

Build quality feels refined, with continuous improvements over earlier 1-Series models making it competitive against Japanese rivals. Rear space is adequate for adults on shorter trips, though taller passengers might find headroom tight with the roof up. Navigation and other amenities are available, creating an inviting environment for both spirited drives and relaxed cruises.

Engine Performance: Straight-Six Thrills

At the heart is a 3.0-litre inline-six petrol engine producing 218 horsepower, propelling the car from 0-62mph in 6.8 seconds and on to a top speed of 148mph. This unit delivers a glorious exhaust note and instant throttle response, making overtaking effortless without constant gear changes.

Unlike some turbocharged rivals, it favors high-revving excitement, building momentum strongly above 5,000rpm. Torque is ample for relaxed motorway runs, though mid-range pull isn’t as seamless as the Audi A3’s 2.0 TFSI. Paired with a six-speed manual or optional step-auto, it embodies BMW’s ‘ultimate driving machine’ ethos, feeling more engaging than larger siblings.

Handling and Ride: Balanced but Not Razor-Sharp

Rear-wheel drive shines through in the 125i’s agile chassis, offering precise steering and strong grip. It feels more balanced and engaging than the front-driven Audi A3, with power delivery encouraging enthusiastic cornering. However, some reviewers note a degree of body flex inherent to convertibles, softening responses compared to the coupe or hatch.

The suspension strikes a firm yet compliant balance, absorbing bumps without excessive roll. It’s not as razor-edged as pricier M models but delivers the ‘BMW fizz’ in abundance—relaxed for daily duties, lively when pushed.

Fuel Economy and Running Costs

Expect real-world figures around 27-29mpg, with official combined economy at 34.9mpg—thirstier than four-cylinder alternatives but acceptable for a six-cylinder sports car. The tank supports a 417-mile range. Benefit-in-kind tax is higher at 27% versus 19% for smaller engines.

Residual values are strong, retaining 57.7% after three years—better than many peers. Servicing costs £495 for inclusive packages, with BMW’s dealer network ranking well in satisfaction surveys.

Standard Features and Options

The SE trim is generously equipped:

• Parking and rain sensors
• Air conditioning
• Leather steering wheel
• Wind deflector (£220 extra)
• Stability control

Options like navigation and enhanced audio elevate it further, keeping it competitive cost-wise against the A3.
