About BMW M340i xDrive
The 2020 BMW M340i xDrive looks like a regular 3-series, but the M in front of the 3 means it gets the same hardware as the rear-drive model, including the M Sport brakes and a limited-slip rear differential. It's unlikely anyone will notice that it sits 0.3 inches taller. If it weren't for the badge, the all-wheel-drive system may also go undetected. However, that changes when Sport mode is activated, the slides into S mode, and the traction mode switches to Sport.
Apply the brakes and pin the throttle, and the 382-hp turbocharged 3.0-liter inline-six builds boost as the torque converter of the eight-speed automatic lets the engine rev to around 3000 pm. Releasing the brake sends the engine's power coursing through the all-wheel-drive system. It shuffles torque to all four wheels. The BMW M340i xDrive squats and rockets away. Upshifts are smooth and unobtrusive in normal driving and snap off like M-80s.The all-wheel-drive shaves 0.3 seconds from the rear-wheel drive's sprint to 60 mph. The test of the rear-drive M340i xDrive resulted in a 3.8-second run to 60 mph, so if BMW's word holds, a 3.5-second zero-to-60 time awaits. That number aligns it with the next rung of performance sedans. This 3-series grips it and rips it.

The BMW M340i xDrive 's all-wheel-drive system will put on a show for them. Putting winter tires on either a rear-driver or an all-wheel-drive M340i xDrive improves braking, handling, and acceleration. Subjectively, the M340i xDrive specific and optional adaptive dampers feel tauter than the rear-driver's dampers, so the ride quality is a touch harsh, even in the Comfort setting. The BMW xDrive system favors the rear. As additional traction is required, torque is sent to the front axle. This setup allows plenty of tail-happy slides. The front tires keep the rears in check to prevent over-rotating in the rear end. The steering is quick enough to catch overenthusiastic slides, but BMW's once-sparkling steering feel remains lost to the computer.
From the EPA's standpoint, there is no fuel-economy penalty. The 25mpg, 22 mpg city, and 30 mpg highway ratings are identical to the rear-drive model. The BMW M340i xDrive overachieved on our 75-mph highway fuel-economy test by averaging 33 mpg, better than the EPA's rating. The OEM parts for BMW M340i xDrive, for example, transmission parts, ignition parts, air intake parts, charging parts and starting parts are now available through the Internet.
