The China Electric Touring Car Challenge, a single-make series featuring race-ready versions of the NIO ES8 SUV, successfully completed its first round last month.
CETC was initially announced early last year but was delayed, with its debut coming on May 18-19 at the new Tianjin V1 Auto World Circuit outside Beijing.
In April, series organizer Zhuhai Formula Racing Development Co. Ltd. (FRD) revealed the NIO ES8 SUV race car which the series uses.
It marks another foray into motorsports for Chinese electric car manufacturer NIO, which already has a team in the ABB FIA Formula E Championship.
Twelve ES8 SUVs were prepared by FRD for the opening event, which featured two races of 20 minutes each.
The four-door SUV produces 480 kW of power and can reach a top speed of over 200 km/h (124 mph) with acceleration from 0-100 km/h (0-62 mph) in 4.4 seconds.
The field included KCMG team owner Paul Ip and FRD founder Kenneth Ma.
Paul Poon claimed the first victory in Race 1 after starting from second, behind pole sitter Thomas Leung who set the only sub-1:20 lap of the circuit.
Leung could only managed to finish the race third, with Oliver Lee making his way up the field from the fourth row of the grid to finish second, just 0.845 seconds behind Poon.
Lee went one better in Race 2 to take the victory by 2.4 seconds over Kenny Chun. A close battle unfolded for third, between Thomas Leung, Stephen Lee and Kenneth Ma.
Following the success of the inaugural standalone event in Tianjin, Kenneth Ma has revealed that a full season calendar will be released in the coming weeks.
