XPeng is claiming a record for a P7 fleet which drove over 3,600km from Guangzhou to Beijing with 2,930 km highway driving under the control of the NGP (Navigation Guided Pilot) and achieved an average of 0.71 human driver interventions per 100km (62 miles), setting a new benchmark for long distance autonomous driving by mass production passenger vehicles. 

"The results demonstrate that it is not only the strongest, but also the easiest to use autonomous driving function for production vehicles available in the market," said He Xiaopeng, chairman and CEO of XPeng.

Under the control of the NGP, the average success rate for lane changing and overtaking was 94.41% during the eight-day 'expedition', started from Guangzhou on 19 March and ending in Beijing on 26 March. The average highway ramp entering and exiting success rate was 92.76% and average tunnel pass-through success rate was 94.95% during the same period.

The route was chosen to cover some of the most complex yet representative road conditions and driving scenarios in China, to fully test the NGP's responses and effectiveness.

The NGP highway system provides navigation assisted autonomous driving from point A to B, based on the navigation route set by the driver, and is available on highways covered by high-precision maps in China. Its full-scenario high-definition positioning capability solves HD-map positioning challenges for China's highly complex road conditions, including areas with no GPS signals.

The NGP is enabled by 14 cameras, five millimetre-wave radars, 12 ultrasonic sensors, centimetre-level high-definition positioning, decimetre-level high-definition mapping, NVIDIA Xavier system-on-the-chip computing platform, and a Bosch iBooster brake system.

Currently, the P7 is China's only mass production car with a 360-degree dual camera and radar fusion perception system for added safety, its maker claims.
