Porsche slams claimed Macan S Diesel moose test failure

Porsche has responded to claims by Swedish magazine Teknikens Varld that its Macan S Diesel performed strangely during a moose test, saying it did exactly what it should have.

PORSCHE HAS RESPONDED to a test conducted by Swedish magazine Teknikens Varld which saw a Porsche Macan S Diesel “perform strangely,” according to the vehicle tester, Linus Projtz. Teknikens Varld was performing a moose test on the Macan S Diesel when the front left wheel locked up after the driver had swerved to the left and then back to the right… only the vehicle ploughed straight ahead for a split second before unlocking and allowing the vehicle to proceed as it should.

”Porsche Macan S Diesel behave very strange in the moose test, most especially because the left front brake locks up in the middle of the maneuver. This is really strange,” Projtz says.

According to Projtz, the test was conducted a number of times and each time the Porsche performed exactly the same, with the front left wheel locking up.
In response to the test, Porsche issued a statement after it had reviewed the footage, saying : “The brake intervention shown in the video is a deliberately applied intervention to prevent the car from rolling over. This is called Active Rollover Prevention (ARP). The precise, momentary application of brake force to the front wheel at the outside of the bend down to the low slip range minimises cornering forces to avoid critical or instable driving conditions such as oversteer, rollover or detachment of the tyre from the wheel. Situations such as these may not be controllable by the driver…

“The intensity of ARP intervention is dependent on vehicle speed and steering angle speed, among others. This means that ARP brake intervention is diminished accordingly at reduced vehicle speed or steering angle speeds. On the other hand, it means that the driving style adopted by Teknikens Värld was very demanding and resulted in the safety function being triggered…

“Porsche uses a comprehensive dynamics test programme which the Macan completed successfully. The driving manoeuvres performed include double lane change according to ISO, slalom with 10 x 18 metres and 10 x 36 metres, the VDA obstacle avoidance test which is very similar to the Teknikens Värld ”moose test”, and the NHTSA rollover safety test. All Porsche cars are designed for maximum safety based on these and other world-wide tests,” a statement read.
