宝马新一代M3细节曝光：全新M3将基于CLAR架构，轴距加长20毫米、车长加长60毫米的同时，车身采用碳纤维，包括碳纤维车顶，实现车重低于现款M3 CS。动力输出或为347千瓦(471马力)，配源自现款M4 GTS的喷水系统。此前传闻、源自M5、偏向后驱设定的智能四驱系统或不会出现在新M3上，以控制车重。此外，宝马或在考虑采用后轮转向技术，以提高新M3的操控性能。
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.
