Denza Z9 GT e³ Tri-Motor Platform Tested in Tight Car Parks: Rear-Wheel Steering (4.62m Turning Radius) & Crab-Walk Mode

[grace_t_syd]

With BYD bringing the Denza Z9 GT to Europe, the UK, and Australia as its flagship luxury shooting brake, here is how the e³ tri-motor independent rear-wheel steering behaves in tight multi-storey car parks:

Real-World Highlights:

• Turning Radius: Despite being 5,180 mm long and 1,990 mm wide, the independent dual rear motors + rear-wheel steering (±10° rear steering angle) shrink the turning radius to just 4.62 metres—tighter than a BYD Dolphin or Mini Cooper!
• 15° Crab-Walk Mode: Both front and rear wheels steer in the same direction to slide diagonally out of tight parallel parking spots without kerbing the 21-inch rims.
• 140 km/h High-Speed Blowout Stability: Tested on track—if a tyre blows at motorway speed, the tri-motor torque vectoring corrects yaw in 10 milliseconds keeping the car dead straight.

A 5.18-metre shooting brake turning tighter than a Mini Cooper (4.62m radius!) is witchcraft. Having independent left/right rear steering actuators + torque vectoring solves the biggest headache of driving a big GT car in old European and British multi-storey car parks.

@HighlandWatt Saw the Denza Z9 GT in person at the Goodwood display—the interior build quality with the dual refrigerators, Devialet lift speakers, and Nappa leather puts the Porsche Taycan Sport Turismo on notice at half the price.

Interesting point about the charging curve. I found that plugging in around 15–18% SOC gives the fastest sustained peak kW before the BMS gently tapers above 80%.

Good catch on those specifications. I checked the service manual torque specs and fuse layout over the weekend and everything matches what you outlined here.

Great write-up! If anyone is on the fence, definitely take a 45-minute test drive on coarse-chip highway tarmac first — the acoustic glass makes a bigger difference than the spec sheet suggests.

Can confirm from my own ownership log — keeping tyre pressures at 2.5 bar cold instead of the dealer-delivered 2.2 bar immediately shaved about 0.8 kWh/100km off my highway average.

Followed this guide step-by-step in the garage this afternoon—took less than 20 minutes and worked first time without any warning lights.
