Some info on Hill descent Control
Hill Descent Control (HDC) holds the vehicle steadily at a pre-determined speed, helping with the job of brake control so that the driver can concentrate completely on steering. This makes the potentially difficult task of driving down a steep hill or over rough ground easy.
Hill Descent Control (HDC), a driver assistant system in four-wheel drive vehicles, can be activated with the press of a button. When travelling at less than 35 km/h, HDC assists you by reducing you to a constant speed of approx. 7 km/h, or 6.5 km/h when reversing. The brake lights come on automatically to warn any drivers situated behind your BMW. The accelerator and tempomat can be used to vary speed between crawling speed and 25 km/h, but if you want, you can of course move faster or slower: HDC then goes into standby mode. It is deactivated once your speed goes above 60 km/h.
HDC is particularly helpful when driving on changeable, loose or slippery downhill surfaces, such as gravel, snow or grass. Together with ABS, it ensures excellent stability while still preventing the wheels from locking if you apply the brakes on a slope. This prevents the vehicle from skidding and permits you to retain control over the steering.
When HDC deactivates, it goes into fade-out mode, gradually reducing braking force and giving you enough time to again take full control of your speed.

Welldone bud you know your engines!! but engine no 2 is incorrect
Engine no 1
BMW 4.4L V8
The performance of the BMW V8 engines is also unusual. Depending on the model, this is achieved through the employment of the most modern TwinPower Turbo technology or by the complex high-speed concept. In vehicles with TwinPower Turbo two equally-large turbochargers work at the same time and supply the engine with compressed air. The central arrangement of the turbos between the cylinder banks of the V8 engines allows a particularly compact design. Combined with the direct fuel injection (High Precision Injection) system, a water-cooled intercooling system and use of the most modern lightweight construction components – like the magnesium aluminium compound crank case – BMW V8 engines reach impressive levels of performance with high efficiency. Thus the 4.4-litre TwinPower Turbo V8 petrol engine in the BMW 550i delivers a full 300 kW (407 hp) and a maximum torque of 600 Nm. And all this with a consumption of 10.4 l/100 km. The V8 engine in the BMW X6M provides even more power. Here a pair of Twin Scroll turbochargers supplies the engine with air. The result is an outstanding 408 kW (555 hp), 680 Nm torque and a litre achievement of 126 hp per litre cubic capacity. The patented cylinder bank-overlapping exhaust manifold provides a particularly even exhaust supply. Thus differences in pressure, which lead to delays in the response mode, are effectively avoided. This means a high level of spontaneous power delivery.
Engine no 3
BMW 6.0L V12
The use of pioneering technology is the reason behind the phenomenal potential of the BMW twelve-cylinder V engine – the unique BMW TwinPower Turbo technology with High Precision Injection, the direct petrol injection system, enables a high compression ratio and thus peak values of 400 kW (544 hp) and 750 Nm maximum torque. In this special technique, petrol is injected directly into each cylinder and mixed with compressed air from two turbochargers before being ignited. Optimal flux and the ideal current in the exhaust system ensure a direct response from the turbochargers. Working together with the variable camshaft control system, double-Vanos, the valve timing is precisely tuned to the engine's requirements. This enables the 6.0-litre engine to fully develop its enormous potential for performance and torque while still delivering excellent fuel efficiency and low emission levels.

Engine no 2
BMW 6 cylinder Diesel twin power turbo engine ( I would call it Tri power because it has a three stage turbo charging process)
The newly developed M Performance TwinPower Turbo six-cylinder in-line diesel engine furnishes the vehicle with remarkable thrust from the word go. This is due in no small part to the three-stage turbocharging process with variable turbine geometry. With its characteristic immediate response, high torque straight from idle, and a wide usable rev range, the BMW M550d xDrive unleashes unadulterated dynamics.
The M genes are borne out by performance figures: 740 Nm catapult the BMW M550d xDrive from 0 to 100 km/h in just 4.9 seconds. This impressive acceleration is accompanied by equally impressive efficiency: average fuel consumption is a mere 6.4 l/100 km, with CO2 emissions of 169 g/km. This combination of dynamic ability and fuel efficiency is unique in the BMW 5 Series vehicle class.
