1994 Porsche 911 Carrera
In many ways the 993 Porsche was the last 911. That’s true because it was the last air-cooled 911 and it was produced as Porsche’s mainstay without the help of SUVs, 4-door and other smaller cars within the model range.
The new 993 was clearly an evolution of the 964. Both cars shared the exact same roof panel but the 993 was considerably updated below the beltline. It had smoother lines, less prominent fenders, kicked-back headlights and flared-out rear fenders.
Inside there was more room in the 993 thanks to positioning all the glass further out. Porsche management kept the 964 interior intact so the designers could only slightly revise the design by including a 4-spoke steering wheel and new center console.
The M64 Flat-6 was developed from the 964 unit with a completely new bottom end and hydraulic valve adjustment. The 3.6 used the twin-spark ignition from the 964, but with heat-resistant RR350 aluminum-alloy in the cylinder heads. Attached to this was a new dual-flow exhaust that employed twin catalytic converters.
The rear suspension was completely revised with a new aluminum sub frame that employed a wishbone-type suspension in an aluminum subframe. The system increased the rear track substantially and also allowed more freedom for motorsports development.
A new feature of the 993 was its automatic rear wing which raised above 50 mph to reduce rear-end lift and add more cooling to the engine.
Main options included a limited slip differential with automatic brake differential (ABD) which applied the brake to a spinning wheel; a sport package with larger roll bars, stiffer springs and shock absorbers; a trip computer; a 6-disc cd changer with 10-speaker hi-fi system; sports seats, full power seats with optional leather and heating system and a Tiptronic S 4-speed automatic.
