In which year was the Porsche 991.1 produced?

[VanHadley]

In 1963, the 911.1 was the first generation of Porsche. The Porsche 911 was first exhibited at the Frankfurt Motor Show, where it was initially named the Porsche 901. However, Peugeot protested because they had already registered all three-digit numbers with a '0' in the middle as model codes for their vehicles. Porsche renamed it to '911' for the first mass production. Related information: 1. Chassis: The 911.1's chassis and drivetrain largely adopted technology from the Porsche 356, including four-wheel disc brakes and rear suspension, while the front suspension was newly developed. 2. Engine: The 911.1 featured a rear-mounted, air-cooled, horizontally opposed engine with a displacement increased to 2.0L and six cylinders. This engine produced a maximum power of 130 horsepower and peak torque of 161 Nm, paired with a new 5-speed close-ratio manual transmission. It accelerated from 0 to 100 km/h in 9.1 seconds and had a top speed of 210 km/h.
