Recently, a third-party organization “China Car Consumer Research and Testing” (CCRT) assessed the performance of advanced driver assistant system (ADAS) that is equipped on 6 different cars, including Tesla Model 3, BYD Han and XPeng P7 [1]. This assessment is based on a 1-million kilometers traffic data collected and different driving scenarios is considered.

These manufacturers claimed that their vehicle can achieve Level 2 autonomous driving, which imply that “hands-off” [2] during driving is achievable. However, manufacturers often overstated their performance when it comes to autonomous driving, as it is a major attractive point for buyers. Also, it is hard for consumers to examinate the performance of these system as they only activate under extreme situation. Thus, the assessment conducted by CCRT is aimed to quantify these performance figure into a unify standard.

Among all contester, XPeng P7 outperform others with an average score of 83.7% in ADAS Test, while the mean score for all is 67.2%. For comparison, Tesla Model 3 only obtain a scores of 70% in this assessment. So, what is the technologies that allow XPeng’s ADAS, namely XPILOT 3.0, overtake the famous “Autopilot” developed by Tesla?

First of all, Tesla’s Autopilot equipped on Model 3 & Model Y is only based on imaging technologies, which relies on the image captured by onboard cameras to perform calculations [4]. Although ultrasonic radar is also included in Tesla’s system, but the maximum working distance of this radar is only 8 meters in Tesla claims.

In contrast, XPeng P7 retained mmWave radar in its XPILOT 3.0 system, and the detection range of mmWave radar is far more than ultrasonic ones, reaching a maximum of 200 meters [5].

This can be very helpful when it comes to extreme situations, like heavy rain or dust storm. Autopilot on Model 3 might fail due to the weak visibility of onboard camera, while XPILOT can be assisted by its mmWave radar.

From the selection of sensors, it can be seen that Tesla aims to provide a system that is safer than traditional driver assistance system, while XPeng try to develop a system that provide the highest safety level among its class.

That is why XPeng system outperform Tesla’s in real-world driving scenarios as it is far more reliable in virtually all-weather conditions.
