2021 BMW M440i 4 Series Coupe Test Drive

The new M440i xDrive Coupe is powered by the B58 3.0-liter inline 6-cylinder BMW TwinPower turbocharged engine producing 382 hp @ 5,800 – 6,500 rpm (an increase of 62 hp) and 369 ft-lbs. of torque @ 1,800 – 5,000 rpm (an increase of 39 ft.-lbs.). The M440i xDrive Coupe accelerates from 0 to 60 mph in 4.3 seconds and can reach an electronically limited top speed of 155 mph or 130 mph depending on the selected wheel and tire combination. The optional Adaptive M Suspension combines all of the best traits of the M Sport suspension with electronic shocks to offer a wide range of adjustment from sport to comfort. Continuously adjustable valves allow the damping force to be adjusted for each wheel individually. Switching between the various Driving Experience Control modes delivers clearly different variations in the damping characteristics – from the well-balanced long-distance comfort of COMFORT mode through to the highly dynamic set-up activated in SPORT. The ADAPTIVE setting allows for automatic adjustment of the steering, damping, accelerator pedal responses and the Sport Steptronic transmission’s shift characteristics to suit the driving style. The control system responds to accelerator and steering inputs to switch the powertrain and suspension to a sportier or more comfortable response. Map data supplied by the standard navigation system can also be used to anticipate upcoming turns. The body of the new 2021 4 Series Coupe is made from hot-stamped steels, multi-phase steels and aluminum alloys to help reduce weight while providing for the most rigid platform possible to allow the suspension to work at its fullest potential. Additional bracing has been added, connecting the front shock towers to the bulkhead and to the front end as well as the rear axle area to help the new 4 Series deliver better agility and precision. The front end of the car uses extruded aluminum side member panels and die-cast aluminum shock absorber housings. The hood, front fenders and doors are now made from aluminum. The very rigid passenger cell and specially designed supporting structures impart an excellent structure for the active and passive safety systems to work together to help protect passengers. A new 48-volt mild-hybrid system is standard on the 6-cylinder M440i xDrive Coupe. The 48-volt starter/generator unit is complemented by a separate 48-volt battery which allows for energy recuperation, storage and use during driving. Energy can be recuperated from deceleration, braking and from excess electricity generated while driving in Sport mode. The excess energy is converted to electricity by the 48-volt starter/generator and stored in the 48-volt battery. This energy can be used by the starter/generator unit to boost performance during hard acceleration or by providing power for electronic systems, thus reducing the load on the engine and improving overall efficiency. The 48-volt starter generator also improves efficiency by allowing the stopped engine to be restarted quickly with little vibration. The Auto Start/Stop function can now turn off the engine while the driver is braking for a stop as soon as the speed drops below 9 mph. Get More Great Car Videos - Subscribe: https://goo.gl/BSIaFc
