Epitome of the water cooled Porsche 4-cylinder series
The Porsche 968 represents the continuation of Porsche's 944 legacy. As you know, the 944 S2 was discontinued after the 1991 model year. Before that time, Porsche had been working on a new model to replace the outgoing 944. At first, it was going to be the 944 S3. As time went on, they realized that the car had too much new stuff to not introduce a totally new model. By late 1991, the 968 was ready. It retained all the good bits of its predecessor, while significantly improving appearance, handling, and performance.
1992 968 Cabriolet
The 968 is an attractive blend of old and new. Its shape hints the 928 and 911 while retaining the clear identity of the 944s. The fully integrated bumper sections are shaped like those of the V8 coupe, the sill extensions are styled in the fashion of the Carrera 2 of 1992. More detailed changes included rearranged air-intakes, 928-style pop-up headlamps, neutral density taillights with red lenses, and the "968" lettering in the center of the rear deck lid.

In coupe form, as shown above, the 968 represents the most balanced GT of any Porsche, and arguably of any in the world. It has the familiar 50/50 weight distribution of the 944, but with more power. The 968's 3.0 liter engine outputs 240 horsepower, making it the world's most powerful normally aspirated 4 cylinder production automobile.
This power, up from 208 in the 944S2, arrived partly from Variocam, which uses a camshaft chain drive with an adjustable tensioner to retard intake valve actuation up to 7.5 degrees. This technique results in lower emissions, more horsepower, and better torque.
The 968, like the Carrera 2, offers
two different transmission types. The standard choice is the new 6-speed
manual. The ratios have been changed a little from the 944S2, but 6th gear
is still no overdrive, and top speed is attained in this drive. However,
only 500 rpms separate 5th and 6th, so they're still close. The other
option is the Tiptronic transmission.
