If the appeal of a thrilling Bavarian compact sports sedan is strong but daily use of a full BMW M3 seems too intense, the milder M340i versions could fit the bill. These upper-level models deliver top comfort, sharp handling, and strong performance while keeping efficiency, practicality, and useful features intact for everyday driving. Power comes from the excellent B58 turbocharged inline-six, an engine also found in vehicles such as the Toyota GR Supra and Ineos Grenadier. This unit produces 382 horsepower and 369 lb-ft of torque, enabling 0-60 mph times of 3.8 seconds in rear-wheel-drive versions according to Car and Driver.

Despite the strong performance, these cars still experience depreciation, though it is not extreme. Original rear-wheel-drive 2021 M340i models started at 55,695 dollars before options, yet used examples now appear from 35,000 dollars based on Kelley Blue Book figures from dealership sales. The xDrive all-wheel-drive version launched at 57,695 dollars and shows a typical fair purchase price of 41,400 dollars. This results in a five-year depreciation of 37.16 percent for rear-wheel-drive cars and 28.24 percent for xDrive models, both better than the 52.6 percent average projected for the 2021 3 Series overall.

How much are 2021 BMW M340i models worth today on the used market?

Many well-used 2021 M340i examples are available, yet prices stay fairly firm for average cars with under 70,000 miles. Current listings indicate a starting point near 29,000 dollars for a clean rear-wheel-drive model, while one-owner low-mileage examples in top condition often reach 40,000 dollars or more. This reflects average value loss between 28 and 47 percent depending on condition. For xDrive versions, prices start around 32,000 dollars for higher-mileage cars but can reach 70,000 dollars for the best low-mileage specimens.

The M340i holds value well, largely because of the B58 engine and its strong reliability record, which attracts buyers seeking a dependable daily driver or family car. Additional draws include solid fuel economy of 26 mpg combined for rear-wheel-drive and 25 mpg for all-wheel-drive models, far better than the M3, plus a 16.9 cubic foot trunk, roomy cabin for most adults, and a quick-shifting ZF eight-speed automatic. These traits make the sedan appealing to performance buyers and help slow its rate of depreciation.
