Porsche Cayenne Turbo vs Audi RS Q8
The starting line-up is comprised of three models. With its 404 kW (550 hp) biturbo eight-cylinder engine and the driving dynamics of a sports car, the #Cayenne #Turbo is heading up the new #Porsche Cayenne generation. In figures: The car accelerates from zero to 100 km/h in 4.1 seconds (or 3.9 seconds with the Sport Chrono Package), and achieves a top speed of 286 km/h. The Cayenne S is powered by a 2.9-litre, 324 kW (440 hp) biturbo-charged V6 engine. From a standing start, the Cayenne S reaches 100 km/h in 5.2 seconds. With the optional Sport Chrono Package, this is reduced to 4.9 seconds. The maximum speed is 265 km/h. The Cayenne with six-cylinder turbo engine and a displacement of three litres delivers 250 kW (340 hp) of power, That means that even the standard model achieves outstanding driving performance. The Porsche Cayenne accelerates to 100 km/h in just 6.2 seconds, or just 5.9 seconds with the Sport Chrono Package, and achieves a top speed of 245 km/h.
The new Cayenne features a brand-new range of engines. The six and eight-cylinder turbo engines originally made their début in the Panamera. Porsche has developed these engines in pursuit of its downsizing concept. All engines have a smaller displacement but deliver more power and torque than their respective predecessor models. The basic engine, combustion processes, gas cycles and charge technologies in the new generation of engines are all optimised for improved performance and even greater fuel efficiency. Take the Cayenne S as an example: In spite of the additional 15 kW (20 hp) of engine power, the new six-cylinder engine boasts an NEDC combined fuel consumption of 9.2 to 9.4 litres of Super Plus fuel per 100 km.
High-performance, variability, everyday usability - the Audi RS Q8 is at the top of its class in the Q product line. The high-performance SUV coupé by #Audi Sport stands for outstanding driving performance, enormous variance with regard to design and driver experience, and unrestricted everyday usability.
As a unique selling point, the #RS #Q8 is 5,012 mm (197.3 in) in length and carries a visually encircling RS sill edge in Manhattan gray as standard. RS-specific strips in the body color give the large #SUV coupé a greater width - 10 mm (0.4 in) at the front and 5 mm (0.2 in) at the rear. It therefore has the space necessary for a more generous track width.
441 kW (600 PS), 800 Nm (590.05 lb-ft) torque between 2,200 and 4,500; 1 rpm; from 0 to 100 km/h (62.1 mph) in 3.8 seconds - the 4.0 TFSI in the new Audi RS Q8 delivers a superior RS performance. With the optional dynamic package plus, top speed has been raised to 305 km/h (189.5 mph).
The turbocharged gasoline engine with direct injection produces a full-bodied and sporty V8 sound, which can be adjusted using the Audi drive select dynamic handling system. Thanks to its mild-hybrid system (MHEV) with a 48-volt main on-board electrical system, the V8 power unit combines maximum performance with high efficiency. The cylinder on demand (COD) system is also onboard as another efficiency component.
The standard all-wheel steering moves the rear wheels of the new RS Q8 via a high-torque electric spindle drive and two track rods. The steering is perceptibly and directly balanced. Even in the central position, it has a sporty ratio of 13.3:1.
The Audi RS Q8 drives on 22-inch aluminum wheels in a 10-spoke star design with 295/40-series tires as standard - the largest ever to be factory-installed on an Audi production model. As an option, 23-inch wheels with an exclusive RS design are available for the RS Q8. The calipers of the RS brake system are painted black as standard but are available in red as an option.
441 kW (600 PS) at an engine speed of 6,000 rpm, 800 Nm (590.0 lb-ft) of torque between 2,200 and 4,500 rpm - the 4.0 l (1.06 US gal) V8 in the new Audi RS Q8 delivers impressive RS performance. The turbocharged gasoline engine with direct injection allows the large SUV coupé from Audi Sport to sprint from 0 to 100 km/h (62.0 mph) in just 3.8 seconds or to 200 km/h (124.3 mph) in 13.7 seconds. At 250 km/h (155.3 mph), it is electronically curtailed; with the dynamic package plus, the Audi RS Q8 can drive at up to 305 km/h (189.5 mph). In the WLTP cycle, the power unit certified to Euro 6d-TEMP consumes an average 12.1 liters of fuel per 100 kilometers (19.4 US mpg), equivalent to 276 grams of CO2 per kilometer (444.2 g/mi).
The V8 has a conventional 90-degree bank angle and a displacement of 3,996 cc (bore x stroke: 86.0 x 86.0 millimeters (3.4 in x 3.4 in)). Its crankcase is made of cast aluminum and weighs just 39.1 kilograms (86.2 lb). A 150-micrometer-thick iron coating is applied via plasma spraying to the cylinder working surfaces, which minimizes friction and wear. An electronic valve arranged centrally in the inside V also regulates the map-controlled piston spray nozzles as required for piston cooling.
