CARS ARENA's video: 2021 BMW 5 Series - Exterior and Interior Details

Heading the portfolio of conventional power units for the new BMW 5-Series is a V8 engine featuring latest-generation BMW TwinPower Turbo technology. The line-up is completed by three more petrol and three diesel engines with either four or six cylinders. The choice of engines for the new BMW 5-Series is spearheaded by a V8 unit boasting the latest BMW TwinPower Turbo technology. Fitted in the BMW M550i xDrive Sedan, the engine's array of high-tech features includes two twin-scroll turbochargers with charge air cooling nestling in the V between the cylinder banks, High Precision Injection operating at a maximum pressure of 350 bar, VALVETRONIC fully variable valve timing and Double-VANOS variable camshaft timing. The V8 generates maximum output of 390 kW/530 hp and peak torque of 750 Nm (553 lb-ft). It delivers its prodigious power to the stirring acoustic accompaniment of the flap-controlled M Sport exhaust system fitted as standard. The range of power units for the new BMW 5-Series Sedan and new BMW 5-Series Touring comprises three other latest-generation petrol engines (two four-cylinder units and a straight-six), which incorporate a twin-scroll turbocharger, High Precision Injection, VALVETRONIC fully variable valve timing and Double-VANOS variable camshaft timing. The High Precision Injection system's injectors are positioned centrally between the valves and operate at a maximum pressure increased from 200 to 350 bar. This allows the fuel to be metered with even greater precision, thereby raising efficiency and also ensuring remarkably clean combustion. The exhaust manifold integrated into the cylinder head - with a water-cooled design that serves to aid thermal management - features on both the 135 kW/184 hp four-cylinder engine fitted in the BMW 520i, BMW 530e and BMW 530e xDrive models and the six-cylinder in-line units producing outputs of 245 kW/333 hp in the BMW 540i and BMW 540i xDrive and 210 kW/286 hp in the new BMW 545e xDrive. The second four-cylinder engine can be found under the bonnet of the BMW 530i and BMW 530i xDrive, where it has a maximum output of 185 kW/252 hp. Two-stage turbocharging and the latest generation of common-rail direct injection provide the technological underpinnings for the three diesel engines (one four-cylinder and two six-cylinder units) in the new BMW 5-Series range. This is the first time that a two-stage system of turbocharging has been used for all the diesel variants in the BMW 5-Series, the quick response of the smaller turbocharger enabling instantaneous power delivery. The 140 kW/190 hp four-cylinder engine fitted in the BMW 520d and BMW 520d xDrive additionally comes with an updated version of the common-rail direct injection system. Solenoid injectors deliver fuel to the combustion chambers at up to 2,500 bar, resulting in incredibly fine atomisation and a remarkably clean combustion process. The six-cylinder in-line engine powering the BMW 530d and BMW 530d xDrive employs two-stage turbocharging for the first time and combines it with a direct injection system whose piezo injectors produce maximum pressure of 2,700 bar. The variable turbine geometry used in the turbocharging system's low-pressure stage lends itself to a continuous build-up of power. There is now 650 Nm (479 lb-ft) of peak torque on tap between 1,500 and 2,500 rpm, an increase of 30 Nm (22 lb-ft) on the previous engine. The maximum output of the new diesel unit stands at 210 kW/286 hp, 15 kW/21 hp more than before. The second straight-six diesel engine for the new BMW 5-Series generates formidable power delivery with an even greater sense of urgency in this latest incarnation. The power unit in the new BMW 540d xDrive boasts maximum output of 250 kW/340 hp - an increase of 15 kW/20 hp - and peak torque of 700 Nm (516 lb-ft) between 1,750 and 2,250 rpm, an improvement of 20 Nm (15 lb-ft). To ensure exceptionally sharp turbocharger response, the system's high-pressure and low-pressure stages both feature variable turbine geometry. Engine response and efficiency also profit from an intake system with optimised air routing, whose redesign enhances acoustic performance too.
