{"slug":"bmw-3-series-vs-mercedes-c-class","title":"BMW 3 Series vs Mercedes-Benz C-Class","url":"https://www.aversusb.net/compare/bmw-3-series-vs-mercedes-c-class","faqCount":5,"faqs":[{"question":"Which car has better fuel economy overall?","answer":"The BMW 3 Series is more efficient overall with 28 city/35 highway MPG versus the Mercedes C-Class at 25 city/35 highway MPG. Both match on highway, but the 3 Series delivers 3 MPG better city performance. Over 120,000 miles, this translates to approximately 1,286 fewer gallons consumed and $4,000+ in fuel savings (at $3.10/gallon)."},{"question":"Which is faster in acceleration?","answer":"The BMW 330i accelerates 0-60 in 5.6 seconds, compared to the Mercedes C300 at 6.1 seconds—a 0.5-second advantage. Both use turbocharged 2.0L engines with 255 hp, but BMW's sport-tuned suspension and transmission calibration deliver quicker launches. The BMW M340i xDrive offers even more performance with 386 hp."},{"question":"Which offers a more comfortable ride?","answer":"The Mercedes-Benz C-Class prioritizes ride comfort and cabin isolation, making it quieter and more refined for passengers. The BMW 3 Series uses a sport-tuned suspension that emphasizes driver engagement and handling feedback, which results in a firmer, more connected feel. Choose the C-Class for maximum comfort, the 3 Series for driving involvement."},{"question":"Are both engines the same size?","answer":"Yes, both the 2026 BMW 3 Series and Mercedes-Benz C-Class use 2.0L turbocharged inline-4 engines producing 255 hp in base configuration. However, the BMW uses an 8-speed transmission while the C-Class uses a 9-speed, contributing to their different driving characteristics and efficiency profiles."},{"question":"Which is better for used car buyers under $20,000?","answer":"For used luxury cars under $20,000, both the 3 Series and C-Class offer strong value as 3-5 year old models. The 3 Series may have lower fuel costs (3 MPG city advantage), while the C-Class may show better long-term reliability records depending on maintenance history. Inspect service records carefully; both have solid durability when properly maintained, though the 3 Series typically commands slightly lower prices on the used market."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/bmw-3-series-vs-mercedes-c-class#faq","url":"https://www.aversusb.net/compare/bmw-3-series-vs-mercedes-c-class","inLanguage":"en-US","name":"BMW 3 Series vs Mercedes-Benz C-Class — FAQ","description":"Frequently asked questions about BMW 3 Series vs Mercedes-Benz C-Class","dateModified":"2026-05-03T05:05:18.063Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/bmw-3-series-vs-mercedes-c-class#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"Which car has better fuel economy overall?","acceptedAnswer":{"@type":"Answer","text":"The BMW 3 Series is more efficient overall with 28 city/35 highway MPG versus the Mercedes C-Class at 25 city/35 highway MPG.
