Porsche 911 Turbo in model year 1989: five gears and improved chassis

The Porsche 911 Turbo new model year undergoes one of the most significant changes of its life since 1974, when the history started. A five-speed gearbox (authors' note: the G50) replaced the four-speed gearbox used so far (author's note: the 930) and a hydraulic one clutch operation is also part of the Turbo novelties.

With the five-speed gearbox, you will be able to sporty upshift with smaller reves drop than previously possible, so that the turbocharger can build up its pressure more quickly. The acceleration phase thus becomes shorter in total, the fast driving in the border area around bends is more harmonious. Something was also done about the comfort: thanks to the hydrailic clutch controls there significantly less driver operating forces required.

The tuning of the suspension of the Porsche 911 Turbo was also thoroughly revised. Larger diameter torsion bars on the rear axle, a modified stabilizer and fine tuned shock absorbers are the most important changes on the chassis.
