Libby Wade BMW, 2017-11-04 19:54:21. Another contributory factor in the international success of BMW i cars are the innovative mobility services which make the experience of driving an electric car that much more pleasurable. These services are another example of how the BMW i brand is leading the way in establishing sustainable mobility in urban centres and beyond. For example, with its ChargeNow service, BMW i allows its customers convenient access to more than 65,000 charging stations in 29 countries. And the brand’s Digital Charging Service has been quick to exploit - in intelligent, convenient and money-saving ways - the new possibilities in energy supply when charging from a home-mounted Wallbox.

The chain drive uses a new concept to reduce the drive power required: the crankshaft drives the balancer shaft via gears, with the shaft lying far down in the V of the cylinder banks. From here chains run to the four camshaft sprockets. These are trioval in shape, i.e. they have a slightly triangular shape, in order to compensate for peak forces. The balancer shaft rotates on roller bearings with particularly low levels of friction.
Paige Dodd Audi, 2017-10-13 19:43:45. The fast, spontaneously and sportily shifting eight-speed tiptronic with optimized shift times is standard on the new Audi RS5 Coupe. The layout of its gear sets and shifting elements results in low drag torques and thereby to a high efficiency level. Its large number of gears very frequently makes it possible to operate the engine close to its ideal load point. The lower gears have short, sporty ratios, while the upper gears are long in order to reduce revs and fuel consumption.
Shannon Griffin Audi, 2017-10-13 19:37:33. In the second generation of the Audi RS5 Coupe, Audi Sport is presenting its first model to feature the current RS design idiom. Its all-new 2.9 TFSI bi-turbo engine produces 331 kW (450 hp) and delivers 600 Nm (442.5 lb-ft) of torque. The standard quattro drive distributes the power to all four wheels.
Mollie Slater Audi, 2017-10-13 19:37:14. Both turbochargers of the 2.9 TFSI unit are centrally positioned inside the V of the engine and each of them supplies a single cylinder bank. The B-cycle combustion process with central direct injection represents a new level of efficiency within the RS family. In the NEDC, the V6 bi-turbo consumes just 8.7 liters of fuel per 100 kilometers (27.0 US mpg), which corresponds to 197 grams of CO2 per kilometer (317.0 g/mi). This is an efficiency gain of 17 percent over the previous model. Also beneficial for the new Audi RS5 Coupe is a drastic reduction in weight. The vehicle weighs in at 1,655 kilograms (3,648.7 lb) - 60 kilograms (132.3 lb) less than previously. A carbon roof with visible fiber structure is also available as an option.

The tailgate opens automatically and the two-door Coupe can be ordered from Audi with optional sensor control. With this, a proximity sensor in the rear bumper reacts to a kicking motion. The tailgate unlocks and opens automatically if the optionally available advanced key is detected.
Kiera Shaw Audi, 2017-10-13 19:40:33. A further efficiency component of the 2.9 TFSI is the thermal management system. The crankcase and the cylinder head have separate coolant circuits. After a cold start, the switchable water pump controls the flow of coolant through the engine so that the oil is warmed up as quickly as possible. The exhaust manifolds are integrated in the cylinder head, and coolant circulates around them which helps ensure rapid warming up. When the engine is warm, this technology lowers the exhaust temperatures - consumption drops drastically, especially when driving in a sporty way. The great efficiency of the V6 bi-turbo is also partly to do with low friction. For example, the fully adjustable oil pump only builds up as much pressure as necessary.
