The BMW top-spec M5 super sedan is shedding weight and also bulking up in the engine room area which is paying dividends for the vehicle.

BMW Weight Wise is Lighter than the Competition

Moreover, it seems car companies are really content with an ounce here and a gram there when they pull weight out of their cars. Thereby, when the carmaker did announce its new M5 C would, in fact, be 230 pounds lighter than the 4243-pound M5 Competition, there was skepticism. Really, the scales don’t lie. In fact, at the weigh-in, this CS registered 4096 pounds, or 147 pounds less than actually the Competition. Though it is not exactly the result that is promised, but regardless it is still a big move in the right direction.

Removal of Sound-Deadening Material and Luxury-Grade Thrones

In an effort to drop those pounds, a carbon-fiber hood does join the standard M5’s carbon-fiber roof. However, the main weight loss does come from removing sound-deadening material. There is also a swap of the luxury-grade thrones for the lightweight racing-style front seats from the M3. However, the BMW did not pull out all the stuffing. The CS does remain placid. It measures at a low 66 decibels at 70 mph. Moreover, it did match a 2018 M5 the carmaker tested on the same surface.

BMW – Extra Horsepower

However, to make the most of the lighter M5, the BMW did wring 10 extra horsepower out of the Competition’s twin-turbo 4.4 V-8. There is 627 horsepower and 553 pound-feet of torque that churns through a ZF eight-speed automatic transmission. Plus an all-wheel drive. The M5 CS does post a 2.6-second time to 60 mph and a quarter-mile speed of 130 mph in 10.6 seconds. Also, the trans does pop off the shift and it does show a commitment in its most race-car-like mode as it slots itself into the right gear under the braking to give you what you need for the corner.
