![]() ![]() With the base 2.0-liter engine, the six-speed manual gets an EPA-estimated 25 miles per gallon in mixed-driving conditions. Let's take the 2022 Subaru Crosstrek as an example. But as modern automatics gained additional gears and relied less on a torque converter, they have overtaken manuals in terms of fuel economy. In the past, it was pretty much a given that vehicles with manual transmissions would be more fuel-efficient than their automatic counterparts. Manual transmissions always get better fuel economy than cars with automatic gearboxes. Just like how the M DCT works, the switching of gears happens in a matter of milliseconds when the driver needs fast acceleration.Myth 1. This automatic DCT includes two drivetrains, one for the even gears and the other for the odd gears. ![]() The non-M models also have a similar version of transmission to the M DCT – the Sport Automatic Dual Clutch Transmission. How does the M DCT work with other BMW M settings to increase performance? Refer to our Complete Guide to the BMW M Button.ħ-Speed Sport Automatic DCT for Non-M Models This is useful when the driver needs to slowly park the car Low Speed Assistant: The M DCT allows the car to accelerate at a slow, snail speed when the driver taps on the gas pedal.Stability Clutch Control: When the car is understeering, the Stability Clutch Control will open the clutch and transfer weight to bring the car back in line.They are the Stability Clutch Control and the Low Speed Assistant. The dry sump allows the engine to be positioned much lower in the chassis, thus increasing the horsepower and cooler oil.īased on the regulated Launch Control setting, the M DCT provides two additional functions to aid in the safety of the vehicle. It helps to increase the engine reliability from the consistent oil pressure. Basically, the oil is stored off of the engine and not in the oil pan. Dry sump lubrication guarantees reliability and maintenance-free function throughout the life of the car.ĭry sump lubrication is the lubricating motor oil management method that increases oil capacity located in a remote reservoir. The drivetrain clutches are controlled by an integrated hydraulic module. Instead, an additional oil and air cooler are installed to help avoid excessively high temperatures inside the M Double-Clutch Transmission. It is not just cooled via the engine’s cooling water circuit. The engine oil is kept within the optimum temperature range. High thermal heat loads typically develop in the drivetrain in a high-performance sports car. The entire gear changing process happens within a matter of milliseconds where each upshift in gear increases the speed at a steady rate. By overlapping the clutch and declutch, the transmission of power remains uninterrupted. So, when disengaged from the second gear by switching up, the third gear is already next in position. In the BMW drivetrain system, one of the drivetrains is set for the even gears (2,4,6) while the other drivetrain is set for the odd gears (1,3,5,7).įor example, when changing gears from the second to the third gear, the third gear would first be engaged in the inactive drivetrain. It was originally developed in Motorsports where two separate drivetrains, each with its own clutch, continuously transfer engine power to the rear wheels. It allows the vehicle to pull off at maximum speed from a standing stop while adjusting the starting rotary speed when the driver presses on the gasīMW DrivetrainThe drivetrain is a collection of parts including the transmission, the driveshaft, the axels, and the wheels. S6 mode: This is the Launch Control function in the manual transmission under the DriveLogic setting.The dynamic clutch control creates a direct traction with the manual transmission for dynamic driving styles The vehicle only changes to a higher gear just before the engine reaches the maximum numbers of revolution D5 setting: Allows the driver to achieve the highest acceleration.D1 setting: The driver can pull off in second gear, and the clutch becomes very light.Settings can vary depending on the driving and the rev speed when each gear is activated.Įxamples of the M DCT with DriveLogic drive settings: With 11 drive settings available on the M DCT with DriveLogic, you can choose either the Drive Mode or the Sequential Mode. Automatic Mode for dynamic comfort (when you are in Drive (D) mode).It allows the driver to shift manually or automatically: There are three options for gear change with the 7-speed M DCT with DriveLogic.
