2017 BMW 4 Series Convertible: 3 Model Review & Specs

The 2017 BMW 4 Series Convertible redefines luxury drop-tops by blending razor-sharp handling with everyday usability. This model year introduces refined engines and updated styling, making it a compelling choice for enthusiasts seeking performance without sacrificing comfort.

Design and Exterior Highlights

BMW’s signature low-slung profile gives the 4 Series Convertible an aggressive stance that turns heads. New bi-LED headlights and a bolder front apron enhance its presence, while the power-retractable hardtop operates in about 20-22 seconds, offering seamless transitions from coupe-like security to open-air cruising.

The wide body and sleek lines emphasize sportiness, with LED fog lights standard across trims. Available in multiple colors, it pairs well with 18- or 19-inch alloy wheels, depending on the package. Unlike softer rivals, its taut lines scream performance heritage.

Engine Lineup and Performance Breakdown

Powertrain choices cater to varied preferences. The base 420i packs a 2.0-liter four-cylinder with around 184 hp, delivering adequate acceleration but lacking excitement. Stepping up, the 430i boosts to 248 hp and 258 lb-ft of torque, achieving 0-60 mph in about 6.3 seconds—smooth and responsive thanks to ample low-end grunt.

Top-tier 440i employs a 3.0-liter inline-six with 320 hp, slashing 0-60 to under 5 seconds for thrilling pulls. All pair with an eight-speed automatic, offering crisp shifts; a manual is available on lower trims for purists. Fuel economy shines: 430i nets 23-34 mpg city/highway, balancing power and efficiency.

This table summarizes key specs, highlighting the 430i’s sweet spot for most buyers.

Handling and Ride Dynamics

BMW’s chassis tuning delivers benchmark agility. Precise steering and balanced weight distribution make it feel planted in corners, instilling confidence on twisty roads. Adaptive suspension (standard on many trims) adjusts for comfort or sport mode, smoothing imperfections without excessive firmness.

• Sharp turn-in reduces body roll effectively.
• Track Handling package enhances stability at speed.
• Rear-wheel drive provides playful dynamics, with optional xDrive for all-weather grip.

Convertible body exhibits minor wobble at high speeds with the top down, but it’s less intrusive than predecessors. Roof-up refinement rivals sedans, with excellent noise insulation.

Interior Quality and Comfort

Step inside to an upscale cabin with supportive sport seats featuring power bolsters—rare in this class. Materials like wood trim and leather exude premium feel, though some note it trails Audi A5 or Mercedes C-Class in warmth.

Front space is generous, with a lower seating position fostering a sporty posture. Rear seats accommodate average adults but suffer from limited headroom due to the roofline. Dual-zone climate control and intuitive iDrive system (with rotary knob and 6.5-10.25-inch screen) stand out for usability, outperforming rivals sans touchscreen.

Convertible perks include a wind blocker to minimize buffeting and folding rear seats for versatility. Higher trims add Harman Kardon audio, keyless entry, and lumbar support.

Practicality and Storage Considerations

Boot space measures 370 liters roof-up, competitive but drops to 220 liters top-down—lagging Audi’s 380 liters. Folding seats help, but it’s no family hauler. Fuel tank supports long trips, and efficiency aids range.

Tech suite impresses: navigation, Bluetooth, and optional heads-up display. Lacking Android Auto in 2017, it relies on robust native systems. Safety includes stability control, multiple airbags, and optional adaptive cruise.

Pricing, Trims, and Value Assessment

Starting around $50,000 for 430i Convertible, prices climb with options. M Sport adds sportier aesthetics and suspension for ~$3,000. Compared to Audi A5 Cabriolet or Mercedes C-Class, BMW offers superior dynamics but pricier packages.

• Base 420i: Better value for casual drivers.
• 430i M Sport: Ideal balance of performance and cost (~$43,000 in some markets).
• 440i: Worth the premium for power enthusiasts.

Used values hold strong, with low-mileage examples under $22,000 available today.

Pros and Cons at a Glance
