Porsche 919 Hybrid
Porsche revealed an evolution of the 919 Hybrid on 11 April 2018, as it broke the lap record in Circuit de Spa-Francorchamps with a lap time of 1:41.77, with Neel Jani behind the wheel. The lap time was 0.783 seconds faster than Lewis Hamilton's flying qualification lap in 2017, previously posting a 1:42.553 in his Mercedes AMG F1 W08, a Formula One car. Jani was also over 12 seconds faster than the standard 919 Hybrid's 2017 pole position lap time of 1:54.097. During the lap, Jani's speed trap was at the Kemmel Straight, with an average speed of .
Porsche 911
A Turbocharged version of the 993 was launched in 1995 and became the first standard production Porsche with twin turbochargers and the first 911 Turbo to be equipped with permanent all-wheel-drive (the homologated GT2 version based on the Turbo retained RWD). The similarity in specification and in performance levels inspired several comparison road tests with the Porsche 959. The 3.6 L twin turbo M64/60 engine produced 408 PS (300 kW / 402 BHP). The performance was outstanding, as 0 to 60 mph has been measured at 3.2 seconds, and the braking was even more impressive 60 to 0 in 2.3 seconds. The car's top speed was measured at at 7,000 rpm. The differences were striking - the 959 had a much smaller engine, sequential turbocharging and a computer controlled all wheel drive system. The 993 turbo had parallel turbochargers, 3.6 litres of displacement, and a viscous coupling for the center differential in the AWD drivetrain. There were basically two years of production 1996 model year and 1997 model years. The main difference was that the ECU in the 1996 model year could not be flashed for an upgrade, while the 1997 could. Additionally, the 1996 year had Porsche crested centre caps on the wheels, while the 1997 had turbo inscribed. Another difference is the motion sensor and map lights above the interior rear view mirror on the 1997 while the 1996 had no such devices.
