2018 Porsche 911 GT2 RS:
The fastest and most powerful road-approved 911 is ready for launch: The new Porsche 911 GT2 RS celebrated its world premiere at the 2017 Goodwood Festival of Speed in the UK. At the heart of this high-performance sports car is a 515 kW (700 hp) biturbo flat engine. Weighing in at 1,470 kg with a full fuel tank, the lightweight two-seater accelerates from zero to 100 km/h in 2.8 seconds. The rear-wheel drive Coupé has a top speed of 340 km/h, and with its near-motorsport drive technology, the new Porsche 911 GT2 RS trumps its 3.6-litre predecessor by 59 kW (80 hp) and achieves a torque of 750 Newton metres (an increase of 50 Nm). The engine builds on that 3.8-litre in the 911 Turbo S at 427 kW (580 hp). In order to increase performance, large turbochargers push an increased volume of process air into the combustion chambers. A new additional cooling system delivers optimum cooling at peak loads and, at very high temperatures, sprays the charge-air cooler with water. This causes the gas temperature to fall in the overpressure range and ensures optimum power output, even under extreme conditions. The customised GT seven-speed double-clutch transmission (PDK) in the new GT2 RS enables power to be transferred with uninterrupted traction. What's more, the specially developed exhaust system is made from extra-lightweight titanium, weighs around seven kilograms less than the system used in the 911 Turbo and delivers an emotional sound without precedent.For the first time ever, Porsche Design is celebrating the debut of the high-performance sports car by releasing a special-issue watch. Offering a nod to the world of motorsport, the Porsche 911 GT2 RS watch is exclusively available to owners of the new vehicle and can only be ordered in conjunction with the new GT model at a Porsche Centre from June 30, 2017...

2017 Audi S5 Sportback:
The new Audi S5 Sportback combines emotional design and functionality with the road performance of a sports car. It accomplishes the sprint from 0 to 100 km/h (62.1 mph) in 4.7 seconds. Its newly developed, turbocharged V6 engine produces 260 kW (354 hp) and consumes just 7.3 liters of fuel per 100 km (32.2 US mpg). With an unladen weight of 1,660 kilograms (3,659.7 lb), the five-door sports coupé is 85 kilograms (187.4 lb) lighter than its predecessor. The sharper exterior design and the numerous S-specific details in the interior underscore its dynamic character. The 3.0 TFSI: The pulsating heart of the new Audi S5 Sportback is a fundamentally new 3.0 TFSI engine. The direct gasoline injection engine with turbocharging has an output of 260 kW (354 hp) and produces a hefty torque of 500 Nm (368.8 lb-ft) from 1,370 to 4,500 rpm. In terms of power and torque it surpasses the previous model, while its weight and fuel consumption are considerably lower. The turbo V6 engine accelerates it from 0 to 100 km/h (62.1 mph) in 4.7 seconds, and on up to an electronically governed top speed of 250 km/h (155.3 mph). In the NEDC cycle, the Audi S5 Sportback only consumes 7.3 liters of fuel per 100 km (32.2 US mpg), which equates to 166 grams CO2 per kilometer (267.2 g/mi). Handling: In the new Audi S5, a fast and smoothly shifting eight-speed tiptronic handles power transmission. The lower gears have short, sporty ratios, while the upper gears are long to reduce revs and fuel consumption. When the driver releases the accelerator pedal at a speed between 55 and 160 km/h (34.2 and 99.4 mph) the automatic transmission switches over to an efficient freewheeling mode.
