Breaking with BYD tradition, the Denza Z lineup is prioritising global markets. Accordingly, its global launch on July 9 will be held at the UK’s Goodwood Festival of Speed. Denza boasts that the new Z will share the limelight with worldwide performance legends at “the century-old hall of racing”. What’s different about the Track Edition The largest change is on the outside, with Denza fitting the Z Track Edition with multiple front vents, a longer front splitter, rear diffuser, and a large spoiler at the back.

The complete aero package provides more downforce at speed, improving the Z’s track performance. Performance-wise, MIIT filings list the Z Track Edition’s top speed as 350 km/h, and Denza claims a 0 – 100km/h time of less than 2 seconds. MIIT also provides the top-trim’s wheel and tyre size: 275/35R21 at the front, and 325/30R21 at the rear. The rear of the Denza Z Track Edition. Powertrain & Specs The Denza Z has three confirmed trims: a convertible, a hard-top roadster, and the now-spotted Track Edition. The same MIIT filings show that all trims share the same tri-motor powertrain, with one front motor pushing 500 kW (670 hp), and two rear motors cranking out a combined 680 kW (912 hp). Total power output for all trims reaches 1,180 kW (1,582 hp), and any performance gains with the Track Edition will come solely from tuning, aerodynamics, grip and weight optimisation. It’s likely to feature BYD’s LFP Blade Battery 2.0, but capacity is currently unknown. The Denza Z, in convertible, hard-top, and Track Edition trims.
