Macan fails to pass the moose test, Porsche says it is only the Active Rollover Prevention [w/video]

As you may know already, the moose test is a hard one for most of carmakers and when the vehicles fail it you know that there is a problem there. The latest vehicle to fail the test is the Porsche Macan, which behave quite strange in the moose test as the left front brake locked up in the middle of the maneuver. This is a disaster, especially from a vehicle built by Porsche.

The moose test was started at 70 km/h (43.5 mph), then the driver swerve the vehicle to the left, then sharply to the right. After the last maneuver the left front brake locks up and the vehicle continued straight ahead for a moment. The test was repeated several times and each time the Macan showed the same behavior.

Meanwhile, BMW X4 and the Range Rover Evoque showed passed the test successfully. According to the Swedish magazine, the tested model was a Macan S Diesel, which is powered by a 3.0-liter V6 turbo diesel engine that generates 254 hp (190 kW). This model is able to accelerate from 0 to 100 km/h (62 mph) in 6.3 seconds, while top speed is 230 km/h.

Porsche also replied the magazine when seeing how their vehicle performed and said that the brake intervention is deliberately applied to prevent the crossover from rolling over. The system, called Active Rollover Prevention (ARP) applies braking force to the front wheel at the outside of the bend down to the low slip range in order to avoid instable driving conditions such as oversteer, rollover or detachment of the tyre from the wheel.

Porsche says that the braking force is applied for a maximum of 300 milliseconds, depending of the driving situations.

We are still eager to find out if the Macan Turbo can pass the moose test as this is a performance-focused version of the German crossover.

For those who don’t know, the Macan Turbo uses a new 3.6-liter V6 petrol engine that generates 394 hp (294 kW) and can accelerate from 0 to 100 km/h (62 mph) in 4.6 seconds when equipped with the Sport Chrono package, while top speed is 266 km/h.

Although there is nothing official, we are sure that Porsche is already working on a solution to fix the steering problem and we expect the Macan to pass the moose test soon.
