The new Boxster is more flat and rear in the track still more broader than in front. The body is slightly longer, while the front overhang shorter. The windshield starts earlier, is more inclined and the top goes further backwards. So overall more successful proportions.

Interesting how the company Porsche further develops their engines. One remains true to the aspirating engine and reduces the displacement in the basic model by nearly 200 cm. For the increased performance, the engine must work harder thus rotate 300 rpm higher. Above, however, is a surprisingly wide engine speed range from 1100 rpm up to the maximum speed.

Of course, the torque is suffering from such an action, there also the Porsche engineers can not perform miracles. Moreover it incurs at a higher speed. But the fuel savings of at least 1.2 litres/100 km are respectable.

In the double-clutch gearbox PDK it is even higher. Here is added a much longer transformed gear, out of the e.g. when accelerating quickly will be automatically downshifted one, two or even three gears. This gear is missing the manual transmission in contrast to the 911.

Add to this the entire modern achievements such as brake recuperation, engine thermal management according engine characteristic map and start-stop. 'Sailed' will be however only with PDK, what you can easily imitate with the manual transmission by removing the gear. At least the Boxster now also has the higher center console, and thus a shorter distance from the steering wheel to the gearshift lever.

A new keyword you have to savour: upshift prevention. Actually, one had if at all, kept to be necessary only for the two-wheel vehicles. Requirement is a deactivated ESP, called PSM at Porsche. Only then are possible this beautiful and not entirely cheap drifts, where now work together suspension and transmission management.

From certain values for steering angle and yaw angle an upshift is suppressed. Perhaps for this situation is necessary the 1100 rpm above the rated speed lying maximum speed. But what happens when even this limit is exceeded and the car drifts still? Yet upshift, release the accelerator or give the user the option to ruin the engine? With the manual gearshift it would be not different.

Variable bearing of power drive also important for vehicle dynamics


The company Porsche calls it 'dynamic transmission bearing', wherein thus in fact the whole power drive, thus also the engine is partially retained. This can now be stiffened electronically controlled and therefore a better acceleration can be achieved, wherein the world develops in 0.2 seconds not much further. But at times of 5 or still a matter of seconds from zero to 100 km/h are such seemingly small improvements significant. 03/12
