BYD's Denza Z9 GT Gets a 2027 European Software Boost for City Autonomy

BYD is preparing to hand its flagship electric grand tourer a meaningful capability jump in Europe. The Denza Z9 GT, the luxury marque’s halo model, will receive an over-the-air upgrade in 2027 that unlocks City Navigation on Driving Assistant (CNOA), pushing its driver-assistance suite into the crowded, tricky world of urban point-to-point driving. The announcement builds on the Z9 GT’s July launch in Europe, where it became the first Denza sold there to carry the tri-motor e3 platform, second-generation Blade batteries and BYD’s Flash Charging hardware.

• Hardware Already Onboard: The sensors needed for CNOA — a LiDAR unit, 12 ultrasonic radars, three millimeter-wave radars and 11 cameras — are fitted to the car today, so the upgrade arrives purely as software.
• What CNOA Can Do: According to BYD, the system handles red lights, roundabouts, posted speed limits, left turns and lane changes around double-parked vehicles, while recognizing pedestrians and cyclists in tight city streets.
• Performance Specs: The European EV variant pairs a 122.49 kWh pack with three motors for a combined 1,140 hp (850 kW) and 892 lb-ft (1,210 Nm), with WLTP range rated at up to 599 km (372 miles).
• Charging Claims: BYD’s Flash Charging stations, rated at up to 1,500 kW, are said to take the car from 10% to 70% in five minutes and 10% to 97% in nine minutes; even at -30°C, a 20%-97% top-up reportedly needs only twelve minutes.
• Positioning and Pricing: At 5,195 mm long with a 3,125 mm wheelbase, the GT sits roughly in Porsche Panamera and Taycan territory. European EV pricing starts at €115,000 including VAT, with UK buyers paying from £105,000 for the EV and £95,000 for the plug-in hybrid DM version.

Why It Matters

European buyers can already order the Z9 GT as either a pure EV or a plug-in hybrid, so the 2027 update is less about new metal and more about keeping an expensive, freshly launched model competitive on the software front — an area where Chinese brands have been moving aggressively. BYD executive vice president Stella Li framed the rollout as delivering on a promise to bring the full God’s Eye suite, CNOA included, to Z9GT owners.

The broader signal is strategic: rather than waiting for a mid-cycle refresh, Denza is using OTA delivery to upgrade an existing fleet, a pattern that is becoming standard among EV makers and one that puts pressure on legacy rivals to match feature velocity. With the Z9 GT already positioned as a technology showcase for BYD’s charging and battery work in Europe, the software layer now becomes the next battleground.
