Kiera Shaw BMW, 2017-11-04 19:54:23. The new BMW i3 and new BMW i3s have a remarkably dynamic character by premium compact electric car standards, and a number of design tweaks have been included to express this to particularly striking effect in their visual appearance too. The unmistakable, avant-garde exterior styling has already picked up the iF gold award for product design and the World Car Design of the Year award along with other accolades, and it has now been enhanced by a number of deft design touches that clearly convey the sporty and stirring driving experience on offer.

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.
Kiera Shaw Audi, 2017-10-13 19:53:03. In the classic Miller cycle, the reduced cylinder charge is detrimental to torque and power output. These aspects have been neutralized by Audi thanks to the implementation of turbocharging and the two-stage Audi valvelift system (AVS). The four camshafts of the 2.9 TFSI can each be adjusted by 50 degrees crank angle. At higher load and engine speed ranges, AVS closes the inlet valve later. The opening time increases from 130 to 200 degrees crankshaft angle, while at the same time the valve lift increases from 6.0 to 10.0 millimeters (0.2 to 0.4 in). Cylinder charging also increases considerably - the 2.9 TFSI revs up powerfully and delivers an impressive output.
Libby Wade Audi, 2017-10-13 19:50:59. The high-output V6 doesn’t just impress with its strong performance, but also with its high level of efficiency. In the NEDC, it consumes just 8.7 liters of fuel per 100 kilometers (27.0 US mpg), which corresponds to 197 grams CO2 per kilometer (317.0 g/mi). This means a 17 percent consumption saving compared with the previous model. A decisive factor in this is the new TFSI combustion process from Audi, which is known as the B-cycle. It has been specifically designed for the partial-load range, which is the predominant operating mode during normal use.
Millie Lowe Audi, 2017-10-13 20:01:47. 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.

This very short opening time keeps the fresh gas flow comparatively small. When the piston moves back up again after reaching bottom dead center, the compression phase starts later than usual. This allows a high geometric compression ratio of 10.0:1 - the combustion then takes place in a relatively small volume. In comparison to the short compression phase, the expansion phase is extended, which results in a high level of efficiency.
Paige Dodd Audi, 2017-10-13 19:47:59. The 2.9 TFSI V6 bi-turbo engine, which Audi developed from the ground up, offers sharp increases in power and efficiency as well as an incomparably full-bodied RS sound. It delivers 331 kW (450 hp). And it‘s peak torque of 600 Nm (442.5 lb-ft) - 170 Nm (125.4 lb-ft) more than the previous model - is available across a broad engine speed range from 1,900 to 5,000 rpm. The top model in the A5 family sprints from 0 to 100 km/h (62.1 mph) in 3.9 seconds, and reaches a top speed of 250 km/h (155.3 mph) - with the optional RS dynamic package it can even reach 280 km/h (174.0 mph).

The increased dimensions of the gran turismo, the 15-millimeter (0.6 in) longer wheelbase and more compact seats increase the space for the driver and passengers. The shoulder room in the front row of seats has been increased by 26 millimeters (1.0 in) and the knee room in the rear by 23 millimeters (0.9 in). The central armrest in the front with storage compartment, the big door pockets, two cup holders and a new, closed stowage compartment beneath the rotary light switch further increase the car‘s everyday usability. One standard feature offering additional convenience to the driver and front passenger is the seat belt height adjustment featuring extending and retracting power belt feeds. The rear bench seat provides space for two passengers and integrates a practical stowage tray between the two seats, as well as a folding armrest. The backrests can be folded forward in the ratio 40:20:40 using the remote unlocking feature in the trunk.
