Front wheel lock caused by Active Rollover Prevention (ARP)
Swedish magazine Teknikens Värld has conducted a moose test with a Porsche Macan in S Diesel specification.
...
Porsche issued a response saying the left front brake locked as a result of the Active Rollover Protection (ARP) system kicking in (for a maximum of 300 milliseconds) to prevent the Macan from rolling over. Porsche went on to say "the precise, momentary application of brake force to the front wheel at the outside of the bend down to the low slip range minimizes cornering forces to avoid critical or instable driving conditions such as oversteer, rollover or detachment of the tire from the wheel."
