The BMW 420i Gran Coupe (2014-2020) is a four-door fastback variant of the 4 Series, blending coupe styling with practical rear access. Powered by a 2.0-liter turbocharged four-cylinder producing around 184 horsepower, it prioritizes efficiency over outright performance. Reviewers praise its handsome design, upscale interior, and balanced handling characteristic of BMW's sport sedans. However, the 420i is often criticized for feeling underpowered compared to six-cylinder variants, with some considering it the "entry-level" option that sacrifices the brand's sporting heritage. It's well-suited for buyers prioritizing style, fuel economy, and premium branding over raw performance—ideal for daily commuting and highway cruising. The Gran Coupe's sloping roofline compromises rear headroom slightly but adds visual flair. Best for singles or couples wanting BMW prestige without the fuel costs of more powerful models.
The BMW 420i Gran Coupe (F36) features BMW's reliable N20 2.0L turbo engine, but early models risk timing chain failure ($3,000-5,000 repair). Expect premium fuel, synthetic oil changes every 10,000 miles, and higher insurance costs. Cooling system components and electronic issues are common. Maintenance costs run 50-75% above mainstream brands, though less than M-series models.
