With its intelligent all wheel drive technology, convincing performance standards, superb road behavior and an abundance of technical ideas, the Porsche 911 Carrera rewrote the new performance-car concept yet again when it was launched in the autumn of 1988, and received rave reviews from the international motor press. Shortly after production started in the spring of 1989, this all wheel drive Carrera was already sold out for more than a year in advance. Since the 1990 model year, Porsche has also been supplying the 911 Carrera 2, a direct derivative of the Carrera 4 with the same 250 bhp engine, suspension, ABS and power steering and the same outstanding aerodynamic features and freedom from lift even at high speeds as exhibited by the Carrera 4 body, but with conventional rear wheel drive. The Porsche 911 Carrera 2 and Carrera 4 enter 1991 model year largely unchanged. There is a firmer sports suspension option, with revised shock absorbers, springs and frontstabilizer. All 911 models have acquired an electronic delay switch for the interior lighting. The new central locking control unit makes it possible to release the trunk, lock the doors and then remove luggage without triggering off the alarm. When the trunk is closed again, the alarm is reset to include it as well. Available since early the 911 Porsche's "Tiptronic" automatic transmission ushered in a new era in gear shift technology. It is a power shift transmission than can operate fully automatically or be overridden by a manual shift action. In other words, this Porsche concept combines full manual control with the advantages of automatic transmission. The Tiptronic lever gate has two shift paths side by side, one for automatic transmission selection and the other for the manual shift. In both sections of the gate, gear shifts take place with no interruption to the power flow. Porsche customers and the public in general have shown immense interest in this revolutionary technological step forward, and accepted it whole heartedly.
