Porsche 912
In 1965, just after the end of Porsche 356 production, they released the new 912 model. It was a 911, but with a 2.0-liter, flat four-cylinder engine And although it delivered just 90 HP, it had modest performance numbers. The car was also significantly less expensive than the 911 and was more fuel-efficient with 36 mpg.
Despite the slow performance, the Porsche 912 turned out to be a major hit for the factory. Between 1969 and 1969, they built more than 32,000 of them. In fact, the 912 proved to be a savior for the whole 911 series. That was because it secured the financial stability of the factory until buyers accepted the 911.
