New dimensional grilles and wraparound headlamps - HID lamps on Denali and halogen projectors on other models - reinforce the confident, refined appearance, while standard LED signature lighting on all models reflect GMC premium attributes. Complementing C-shape rear lighting graphics add a cohesive detail to the design. Premium cues distinguish the Acadia Denali. Like all Denali models, it features a dimensional chrome grille, along with integrated chrome side trim, chrome-accented door handles, a chrome lower-rear fascia and specific six-spoke wheels.

They flare outward to provide effective folding and crushing performance during small overlap frontal crash situations. The new GMC Acadia retains a front-drive layout with available all-wheel drive. All models feature a new drive mode selector, which allows the driver to alter chassis and powertrain attributes to suit a variety of driving conditions. Front-drive models offer Normal (2x4), Snow, Sport and Trailer/Tow modes, while AWD models offer 2x4 (AWD disconnect), 4x4, Sport, Off Road and Trailer/Tow modes.

The new GMC Acadia offers a greater emphasis on refinement, while remaining instantly recognizable with an evolution of the vehicle signature, professional grade design cues such as a chrome-trimmed grille, squared off and flared wheel arches and wraparound rear side windows with dark D-pillars. "It a confident design influenced by extensive customer input," said Helen Emsley, executive director, Global GMC Design and User Experience. "The original Acadia was very truck-inspired, but the new model has a decidedly SUV influence conveyed in sculptural details, softened corners and a sleeker windshield angle."

The high-performance Coupe combines elegant aesthetics with high everyday usability. The car‘s V6 bi-turbo has been developed from the ground up and provides significantly more performance coupled with higher efficiency," said Stephan Winkelmann, CEO of Audi Sport GmbH, in describing the new model.

Like with all new V6 and V8 engines from Audi, the turbochargers are installed within the 90-degree angle of the cylinder banks, and thus the exhaust side of the cylinder heads is on the inside, while the intake side is on the outside of the engine. This layout enables compact construction and short gas flow paths with minimal flow losses - the 2.9 TFSI responds extremely spontaneously to movement of the accelerator pedal.

In the area around the inlet valve, this makes possible a geometry which, in interaction with the inlet ports, allows for targeted mixing up of the gas charge. The common-rail system injects the fuel into the combustion chamber with 250 bar of pressure - the high injection pressure ensures a homogeneous spray pattern and consequently a uniform propagation of the flame front.

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.

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.
Caitlin Duncan Audi, 2017-10-13 20:03:47. 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.
