Xpeng P7 packs in a 706km NEDC range

The Xpeng P7 intelligent sports sedan’s driving range was verified at NEDC 706km, in an announcement made by the Ministry of Industry and Information Technology of China (MIIT).

The Xpeng P7 sports sedan was verified to have a NEDC range of 706km. It is the longest range among electric vehicles available in China. The model listed in the MIIT announcement is the RWD version, with 196kW maximum power, 390N·m peak torque and 12.5kWh/100km power consumption.

The Xpeng P7 is equipped with the latest generation of the world's leading prismatic battery pack, with a pack capacity of 80.87kWh and an energy density of 170Wh/kg. It integrates E-motor, transmission and control system in its high-performance 3-in-1 electric drive system. Compared with the traditional distributed electric drive layout, this gives higher efficiency, a more compact structure, lighter weight, more uniform interior layout, and greater reliability.

The volume of the entire electric drive system is only 18.6L, and power density reaches the industry-leading 2kW/kg level. The maximum efficiency of the motor system is >95%, with the NEDC efficiency greater than 85.5%, leading to longer battery life and stronger performance.

Wind resistance coefficient is also critical to cruising range. For the P7, every 0.01 decrease in wind resistance coefficient increases NEDC driving range by about 8km. The P7 has its own streamlined profile unique to its coupe format, with a duck-back extension, a semi-hidden wiper, low-resistance exterior mirrors, and low-resistance wheel rim covers. The air grille and near flat low wind resistance chassis have been refined to reach an ultra-low wind resistance coefficient of Cd0.236, after more than 30 optimisation schemes implemented.

The Xpeng P7 uses a front double wishbone and a rear five-link suspension, with unsprung mass reduced by optimisation of suspension material and layout. The upper and lower control arms, steering knuckles, and damper forks of the P7 are made of aluminium alloy, which significantly reduces weight compared to traditional cast-iron materials. The rear suspension swing arms are made of stamped parts, superior in strength and weight.

The iBooster intelligent braking assist system provides the Xpeng P7 with best pedal feel, more accurate braking force, and longer cruising range - a prerequisite for achieving higher levels of automatic driving assistance in future.

The Xpeng P7 will be officially launched and delivered to the Chinese market in 2Q 2020.
