近日外媒披露了新一代2020款宝马M3更多细节，新车功率将更强劲，同时车身进一步轻量化。预计下一代M3功率将达到465马力，比现行版M3CS还高出了11马力。据外媒报道，新车将采用取自M4GTS的引擎水喷冷却系统，以便能更好的降低气缸温度，提升运行效率。更棒的是，2020款M3还将采用比M3CS更轻的车身。这主要是由于该车与M5和M7共享了CLAR平台，不仅车身更多的使用了碳纤维材质，而且车顶也是碳纤维的。因此，M3车重不会超过M3CS的1585公斤。车重的降低是在车身尺寸增加的基础上实现的，这就很不简单了。预计新车将比老款车轴距增加20毫米，车身长度增加60毫米。不过，为了避免车重增加，该车将不会提供M5的分时四驱系统。宝马还考虑为新一代M3增加主动后轮转向，这也得益于该车采用的是CLAR平台。如果真是这样，将进一步强化M3的灵活性，特别是高速行驶时的灵活性。
New BMW M3 To Add Power, Remove Weight Compared To M3 CS
The M3 CS has already made huge waves with its high performance figures and trimmed-down weight, thanks largely to the extensive use of carbon fiber parts. However, BMW is up to something better for the 2020 M3, with even more powerful engine and lighter body in a regular non-CS package.
In a report by Autocar, the next-generation sports sedan is expected to get 465 horsepower for its standard version. If true, it will be 11-hp higher than the M3 CS. The magazine said that it hasn’t been confirmed yet, but the power boost will be coming from the use of water-injection system used in the M4 GTS, for cooler cylinders therefore more efficient running. Even better, the 2020 M3 will also get a lighter body than the M3 CS. This is due to the use BMW’s CLAR structure that underpins the M5 and M7. It will not only employ extensive use of carbon fibers in the body, but more importantly, will use an all-carbon roof. With that, the M3 won't cross the 1,585-kilogram (3494-pound) mark – the already notable weight of the M3 CS.
The weight loss is quite surprising since it’s predicted that the M3 will grow a bit from its predecessor; 20 millimeters (0.79 inches) increase in wheelbase and 60 millimeters (2.36 inches) increase in overall length. BMW is also expected to rule out offering M5’s part-time, four-wheel-drive system to avoid weight increase.
BMW also considers adding active rear-wheel steering technology to the next-generation M3 since it’ll be built on CLAR structure. If this pushes true, it will enhance the M3’s agility and increase high-speed agility, and will be the only 3 Series model to have such technology up its sleeve.
