M340i xDrive

The BMW M340i xDrive represents the high-performance variant of BMW's G20-generation 3 Series sedan, positioned just below the full M3 in the lineup. It features BMW's acclaimed B58 turbocharged 3.0-liter inline-six engine (B58B30O1) producing 382 horsepower in North American specification (374 HP in European markets with particulate filter) and 369 lb-ft of torque available from 1,800 to 5,000 rpm. Newer models incorporate a 48-volt mild-hybrid system adding up to 11 additional horsepower. Power is delivered through an 8-speed automatic transmission to BMW's xDrive intelligent all-wheel-drive system, which can vary torque distribution to optimize traction and handling.

Performance is impressive with 0-60 mph achieved in just 3.7 seconds and quarter-mile times of 12.2 seconds at 112 mph, while top speed is electronically limited to 155 mph. The xDrive system enhances all-weather capability and launches while maintaining BMW's characteristic rear-biased handling dynamics, particularly in sport modes where power is intentionally biased rearward to allow controlled rear slip. The M340i features M Sport suspension with optional Adaptive M Suspension offering electronically controlled dampers, along with an M Sport rear differential capable of full locking. The M340i xDrive offers near-M3 performance levels in a more refined, daily-usable package, making it popular among enthusiasts seeking serious performance without the compromises of a dedicated M car.
