BMW 4 Series 2017 Facelift Review: Refined Premium Coupe

The 2017 BMW 4 Series facelift delivers evolutionary improvements to an already strong lineup of premium coupes, convertibles, and Gran Coupes. With updated engines, subtle exterior revisions, and chassis tweaks, it balances everyday usability with thrilling performance. This update keeps the model competitive against rivals like the Mercedes C-Class Coupe and Audi A5, emphasizing BMW’s signature driving dynamics.

Exterior Design Evolution

BMW’s designers focused on understated refinements for the 2017 model year. The front fascia gains fuller LED headlights as standard, with optional adaptive beams for better nighttime visibility. Revised bumpers adopt a sportier profile, complemented by larger air intakes and new alloy wheel designs ranging from 17 to 19 inches. At the rear, slimmer taillights and quad exhaust tips on higher trims enhance the aggressive stance.

These changes align the 4 Series more closely with the updated 3 Series, yet preserve its distinct coupe silhouette. The low roofline and wide stance contribute to a purposeful look, measuring about 4.64 meters long with a 2.81-meter wheelbase. Paint options expand to include new metallic shades like Snapper Rocks Blue, appealing to style-conscious buyers.

• Key exterior updates: Full-LED headlights, refreshed bumpers, new wheel styles.
• Dimensions: Length 4,641mm, width 1,825mm, height 1,389mm (coupe).
• Weight: From 1,520kg, varying by engine and body style.

Interior Refinements and Comfort

Inside, the cabin remains driver-centric with high-quality materials, though it trails rivals in opulence. New chrome accents surround air vents and console switches, while gloss black trim adds modernity. Optional digital instrument clusters mimic Audi’s virtual cockpit, displaying navigation and driver aids clearly. The iDrive infotainment receives a tile-based interface, improving navigation and connectivity, though it lacks native Android Auto or Apple CarPlay in base form.

Seating offers excellent support with power adjustments and memory on most trims. Rear space accommodates two adults comfortably, better than expected for a coupe. Cargo capacity is practical at 445 liters in the coupe, expanding with seats folded. Packages like Luxury or M Sport introduce premium leathers, wood, or aluminum trims.

Powertrain Options and Efficiency

The 2017 update renames and refines engines from the prior 3 Series lineup. Petrol choices include the 430i (2.0L turbo, 252hp), 440i (3.0L turbo inline-six, 326hp), and M4 Competition variants. Diesel options like the 420d (190hp) and 435d (313hp) prioritize torque and economy. All pair with an 8-speed automatic, with xDrive all-wheel drive available.

The 440i stands out with 0-62mph in 4.8 seconds and a 155mph top speed, yet claims 32.5-41.5mpg combined. The 435d offers similar pace with better efficiency at around 50mpg. These figures beat many rivals, aided by updated EU6-compliant units.

• 430i: 252hp, 7.2s 0-62mph, 44.1mpg.
• 440i: 326hp, 4.8s 0-62mph, 32.5mpg.
• 435d: 313hp, 4.8s 0-62mph, 52.3mpg.

Dynamic Handling and Ride Quality

Chassis enhancements include stiffer suspension tuning for both standard and adaptive M Sport setups. This sharpens steering response and body control without sacrificing comfort. The 440i excels on twisty roads, blending compliance over bumps with precise cornering. Adaptive dampers allow Normal, Sport, and Sport+ modes, optimizing for varied conditions.

Braking is strong, with larger discs on performance packs. The Track Handling package adds variable steering and carbon-ceramic options for enthusiasts. Reviewers praise its balance, though some note reduced steering feel compared to older BMWs.

On motorways, refinement shines: minimal wind/road noise, stable at high speeds. The diesel 420d proves ideal for long hauls with quiet operation and low costs.

Safety and Technology Features

Standard safety includes airbags, stability control, and run-flat tires. Optional Driver Assistance Plus packs forward collision warning, autonomous braking, blind-spot monitoring, lane keep assist, and 360-degree cameras. These elevate crash avoidance, earning top Euro NCAP ratings pre-update.

Connectivity features USB, Bluetooth, and optional Harman Kardon audio. Wireless charging and gesture controls appear in loaded models.

Trim Levels, Pricing, and Rivals

Starting around £33,000 for the 420i, prices climb to £45,000+ for 440i M Sport. SE trim offers value; Sport and M Sport add aesthetics and dynamics. Rivals include Audi A5 (refined but less engaging), Mercedes C-Class Coupe (luxurious interior), and Porsche 718 Cayman (purer sports car).

Ownership Experience and Reliability

BMW’s 3-year warranty covers unlimited mileage. Running costs favor diesels, with 435d under 130g/km CO2. Resale holds strong due to desirability. Maintenance intervals are 2 years/18,000 miles; expect premium servicing costs. Reliability is solid, though electronics can glitch.

Pros and Cons

• Pros: Engaging handling, efficient engines, practical space, strong performance.
• Cons: Interior quality lags rivals, no standard touchscreen mirroring, firm ride on base suspension.
