The car experienced a suspension failure when undergoing race testing at the Sydney Motorsport speedway in Eastern Creek prior to WSC. A bolt on the left-hand front suspension had fractured during braking tests, causing the car to drop out and skid for about 30 m. They managed to get their car repaired, but ended up withdrawing somewhere around Tennant Creek or Barrow Creek on Day 3 of WSC 2017 due to safety concerns over their suspension. They did not complete WSC 2017.

Performance
| Top Speed | 140 km/h |
|---|---|
| Average Power Consumption | 18.3 Wh/km @ 60 km/h |
| Range | 800 km (solar + battery) |
Note: Apparently, at 60 km/h, Violet can operate solely on solar output. This means that they consume less than 1100 W / 60 km when travelling at 60 km/h.
