Stumbled on an electric supercar costing less than a Porsche 911 GTS? Meet Denza Z, wowing at Goodwood Festival of Speed. The base model has 1,580hp, hits 0-62mph in 2.25s, tops 186mph, charges fully in under 10 mins, and seats 4 as a solid grand tourer. Its Racing version cuts 0-62 to 1.96s (217mph) with track tweaks; a Spider convertible exists. This fall, a 1,973hp Nürburgring special will chase lap records, hitting 0-62 in <1.7s with massive downforce. Ditch the 911 GTS for this EV, or stick to gas engine rumble?
